Overview

Amazon’s marketplace is evolving, and so are the strategies of savvy brands and agencies. In late 2024, Amazon sent shockwaves through its vendor network by announcing the termination of many Vendor Central (1P) accounts by November – effectively nudging those brands to become third-party sellers. For Amazon agency professionals and brand owners, this seismic shift raises a key question: How can you successfully transition from being a 1P Amazon vendor to a 3P seller?

Shifting from Vendor Central to Seller Central isn’t a simple flip of a switch – it’s a comprehensive business transformation. Done right, it can unlock greater control over pricing and branding, improved profit margins, and more direct customer engagement. Done haphazardly, it risks supply chain snags, profit erosion, and organisational overwhelm. This guide distills core insights and practical strategies shared by Amazon expert Zack Rubin (Founder of Red-Tail Consulting) in a MerchantSpring webinar, reframing them into a step-by-step roadmap for a successful 1P-to-3P transition. We’ll explore why many brands are making the switch, how to navigate the operational challenges, and what it takes to come out on top as a third-party seller on Amazon’s marketplace.

1P vs 3P on Amazon: Why Brands Are Switching

First, what do we mean by 1P and 3P? In Amazon parlance, 1P (first-party) refers to vendors who sell their products wholesale to Amazon Retail. Amazon acts as the retailer – buying stock from the brand, setting retail prices, and selling to end customers (your product pages show “Ships from and sold by Amazon”). In contrast, 3P (third-party) refers to brands or independent sellers who sell directly to consumers on Amazon via the Seller Central platform – you become the retailer of record, managing your own pricing, listings, and fulfillment (offers appear as “Sold by Your Brand, Fulfilled by Amazon” if you use FBA).

Why the recent surge in 1P-to-3P transitions? Simply put, the balance of power has been shifting. Third-party sellers now account for the majority of Amazon’s sales volume, and Amazon is increasingly prioritising the marketplace model for its efficiency and profitability. Recent reports confirm that Amazon is actively encouraging smaller vendors to move to 3P as part of a strategic realignment(amplifyy.com). For brands, the motivation to switch often boils down to two big factors: control and margin.

On Vendor Central, Amazon might have offered convenience and scale – you ship bulk inventory to Amazon, and they handle the rest – but it came at the cost of control. Amazon sets your product prices (often discounting them to match other retailers), controls the customer experience, and owns all the shopper data. Many vendors have watched Amazon undercut their MSRP, struggle to support new product launches, or dilute their branding on the product detail pages. Meanwhile, profit margins can suffer due to Amazon’s terms and deductions (co-op fees, chargebacks, marketing accruals, freight allowances, etc.). In short, you’re trading autonomy for Amazon’s retail muscle.

In a 3P model, you regain control. You set your own prices and discounts, decide how to present your brand, and get direct visibility into performance metrics and customer interactions. It’s no wonder that regaining pricing and brand control is the number-one reason brands cite for moving to 3P. “Lack of pricing control is the biggest motivator… In a 3P model, you’re in the driver’s seat on pricing,” notes e-commerce advisor Ruben Alikhanyan. You won’t wake up to find Amazon unexpectedly selling your product at a 20% markdown – you decide if and when to adjust prices.

Brands are also finding that a 3P approach can supercharge marketing agility and new product launches. Under 1P, launching a new SKU can be painfully slow – you have to persuade Amazon to stock it, and their orders depend on conservative demand forecasts for unproven products. As a 3P seller, you can list new products immediately, set up Prime-eligible stock via Fulfilled by Amazon (FBA), run Amazon Ads and promotions from day one, enroll in programs like Subscribe & Save or Vine for reviews, and essentially execute a go-to-market strategy on your own terms. Many larger brands will even use a hybrid approach – launching new products as 3P to build up demand and reviews, then later transitioning those products to 1P once they’ve proven themselves. This illustrates how much easier it is to gain momentum for new products as a seller, compared to waiting on Amazon Retail’s support.

Finally, there’s the allure of better margins. Instead of selling to Amazon at a 50-60% wholesale discount, as a 3P seller, you capture the full retail price and simply pay Amazon a referral fee (roughly 15%) plus fulfillment fees if using FBA. Yes, you’ll take on fulfillment costs and handle returns, but many brands find they can still come out ahead – especially if they optimize operations. Plus, you avoid those frustrating vendor deductions and chargebacks that used to quietly chip away at your net revenue. As Amazon itself recognises, the 3P marketplace offers the company higher margins and lower risk than the vendor model – and if managed carefully, some of those efficiency gains can translate to higher profitability for you as well.

In summary, brands are switching to 3P for greater control, agility, and potentially higher profitability. Amazon’s own policies are catalysing this trend, but it’s also fueled by success stories of sellers building thriving businesses with full control over their destiny. That said, moving to Seller Central is not without challenges – and it certainly isn’t right for every product or every brand. In the next sections, we’ll explore the key benefits of the 3P model, the potential downsides to plan for, and a blueprint for executing the transition smoothly.

Benefits of the 3P Model: Control, Margins, and Growth Potential

Switching to a third-party seller model on Amazon can feel like trading a cushy desk job for the life of an entrepreneur – more freedom, but more responsibility. Here are the core benefits of the 3P model that attract brands and justify the extra work:

🚀 Full Control Over Pricing and Promotions: As a 3P seller, you set your own retail prices. No more surprise price cuts due to Amazon’s price-matching algorithms. You can maintain consistent pricing to protect your brand’s premium image or enforce MAP (Minimum Advertised Price) policies. If market conditions change, you decide whether to run a strategic discount or coupon. This pricing autonomy often leads to healthier margins. You’re no longer constrained by Amazon’s wholesale cost or retail markup; instead, you can price based on real-time marketplace dynamics and your profitability goals. During peak seasons or when costs fluctuate, the flexibility to adjust pricing on the fly is invaluable. In short, you regain the steering wheel for your product pricing strategy – a huge win for brands tired of margin erosion under Vendor Central’s control.

💡 Brand Presentation and Content Control: Third-party sellers have full control over their product listings – titles, bullet points, descriptions, images, A+ Content – whereas 1P vendors often had to go through Amazon’s processes or support teams for content changes. On Seller Central, you can optimise your content freely and quickly. Want to test a new title format with better keywords? Go for it – changes go live in minutes or hours, not weeks. You can build out a branded Amazon Storefront, use Brand Registry tools to enhance content (like Brand Story and Posts), and ensure your Amazon presence aligns with your broader brand messaging.

This is especially crucial in categories like premium beauty or luxury goods, where storytelling and brand image matter. Zack Rubin pointed out that in categories with higher price points and customer expectations (like prestige beauty), being 3P allows you to “really wow [customers] with a service experience” if something goes wrong – potentially turning a one-star review situation into a five-star review by providing above-and-beyond support. That level of personalised customer care and curation is only possible when you, not Amazon Retail, are managing the listing and the buyer relationship.

📊 Direct Access to Data and Customer Insights: Seller Central provides a wealth of real-time data that vendors simply couldn’t access. You gain visibility into your daily sales (often updated multiple times per day), inventory levels, and detailed traffic and conversion metrics for each ASIN (sessions, page views, conversion rate, Buy Box percentage, etc.). This data empowers you to make faster, smarter decisions. For example, if a listing’s conversion rate suddenly drops, you can investigate and react immediately – perhaps by adjusting the content, price, or inventory – rather than finding out days later via a lagging Vendor Central report. You also have more insight into who your customers are and how they interact: while Amazon still keeps most customer information private, 3P sellers can at least see buyer addresses for fulfillment, receive buyer messages, and glean patterns from reviews and the Q&A section.

Programs like Subscribe & Save give you a base of loyal repeat customers to nurture. All these touchpoints mean you can start to build a more direct relationship with your end consumers. It’s not the same as owning all the data, but it’s worlds better than Vendor Central’s opacity (where Amazon treated the customer as their customer and shared very little with you). Many brands find that having this data allows for better demand forecasting, more effective advertising optimisations, and faster product development feedback loops.

📈 Agility in Launches and Inventory Management: When you control your own seller account, you’re free to introduce new products and manage your catalogue on your own schedule. As mentioned earlier, a new product launch can be executed much more aggressively on 3P: you control the stock you send in, you don’t have to wait for a purchase order, and you can even fulfill via FBM (Fulfilled by Merchant) initially if needed to test the waters. This means faster time-to-market for innovation. Additionally, if a product isn’t performing or is seasonal, you can scale back or liquidate inventory on your own terms (using Outlet deals, clearance pricing, or removal orders), rather than pleading with Amazon Retail to not overstock or to mark down your items.

In essence, you gain supply chain agility – shipping inventory in and out at will – which is a double-edged sword (more on the operational burden shortly) but certainly enables a more responsive and lean inventory strategy. Some brands leverage this by testing far more SKUs on Amazon than they ever could as a vendor, since they can list items, see if they gain traction, and then decide whether to invest more or drop them, all within their own control.

💰 Potential for Higher Margins: Every brand’s numbers differ, but moving to 3P can significantly improve unit economics in many cases. As a vendor, you might have been selling at roughly 50-60% of the retail price (wholesale), and then seeing Amazon chip away at that with various fees and allowances. As a seller, you keep roughly 85% of the retail price (after the typical ~15% referral fee), and then you pay fulfillment costs – which vary by item size/weight and chosen fulfillment method. For many products, the math works out in favour of 3P, especially if you optimise your packaging and logistics. You also avoid Amazon’s incremental vendor fees (co-op marketing funds, damage allowances, accruals, etc.), replacing them with more predictable costs (FBA fees, monthly storage fees by volume, etc.).

One big advantage is transparency: no more surprise deductions months later. Your Amazon payouts as a seller are straightforward and trackable. Some brands transitioning to 3P discover that by either adjusting their pricing strategy or improving efficiency, they can net higher profit per unit than they did as a vendor – all while keeping retail prices to consumers the same or only slightly higher. Of course, it’s critical to validate this on a SKU-by-SKU basis (we’ll discuss that in the next section). Not every product will be more profitable on 3P, but many will – and you have the ability to shed or rework the unprofitable ones when you’re in control.

In short, the 3P model offers an entrepreneurial freedom on Amazon that can translate into superior brand-building and profitability. You get to be the boss of your Amazon presence, with all the upside and responsibility that entails. But as Zack Rubin cautions, “it’s not a one-size-fits-all” solution – and indeed, recent fee changes (like higher FBA inbound shipping fees) mean staying 1P might still make sense for some heavy, bulky, or thin-margin products. In the next section, we’ll look at those challenges and how to overcome them.

Challenges and Pitfalls in a Vendor-to-Seller Transition

Despite its advantages, transitioning from Vendor Central to Seller Central comes with a fair share of challenges. It’s a bit like moving from a catered, all-inclusive cruise to captaining your own ship. Here are some common pitfalls and how to mitigate them:

🔍 Financial Feasibility (Do the Math First!): The first obstacle is profitability. A product that was profitable as a 1P item might not be profitable as a 3P item once you factor in Amazon’s referral fee and FBA fulfillment fees (which are largely based on item size and weight). Zack Rubin emphasises that one of the first steps in any transition is to do a detailed SKU-level financial analysis. The same product that “worked” on your vendor account may not work on your seller account at the same consumer price point because the fulfillment costs are so much higher if a product is heavy or bulky.

In Vendor Central, Amazon’s purchase price to you might have included various allowances (e.g. 10% marketing co-op), but Amazon handled the picking, packing, and shipping costs. In Seller Central, you are paying to ship that item to the customer (if FBA, the fee might be several dollars per unit) plus the cost to send inventory into Amazon’s warehouses in the first place. For large, low-priced items (imagine a $10 bulky household item), the economics may fall apart on 3P once those fees are added.

Solution: Do the math before you leap. Model out the FBA fees for each ASIN (Amazon provides a fee calculator tool) and see what retail price you’d need to charge to remain profitable after fees. You might find you need to raise prices as a seller – which only works if the market will bear it. Identify which SKUs just won’t pencil out under 3P economics; you may choose to keep those with Amazon Retail (if Amazon allows) or simply drop them from your Amazon catalogue if they can’t profitably be sold without 1P support. Many brands discover that their long-tail items that are heavy or oversized might be better off not being offered on Amazon at all if 1P is not an option. On the flip side, you will likely identify some products where the 3P margin structure is significantly better – those will be the stars of your new strategy. The bottom line: do a SKU-by-SKU profit analysis and go in with eyes open on what will improve, what might suffer, and what might need adjustments in a 3P model.

🚫 Amazon ASIN Restrictions (Gating Issues): A tricky hurdle some transitioning vendors encounter is ASIN or brand gating. Amazon sometimes prevents a brand from listing certain products on Seller Central if those ASINs are actively supplied via Vendor Central. In practice, when you try to list your existing 1P ASINs on a new seller account, you might get an error that you’re not authorised to sell that product – essentially, Amazon’s way of saying “we prefer this item remain in the retail (1P) channel.” This tends to happen especially for high-volume or strategic products that Amazon doesn’t want to lose from its retail assortment, but it’s not consistent – some brands move all their products over with no gating issues, while others hit a wall on key items. It can be an unpleasant surprise to set up your seller account only to find Amazon itself is blocking you from listing your best-selling ASINs.

Solution: Test early and plan accordingly. Before you fully commit to the transition, create your Seller Central account (if you haven’t already) and attempt to list a few of your current 1P ASINs. Do this quietly on a small scale to probe for any restrictions. If you encounter blocking, you have a few options: (a) Discuss with your Vendor Manager. If you have an Amazon vendor manager or vendor support contact, be transparent about your plans and see if they can assist in removing any brand/ASIN gating. In some cases, Amazon can manually ungate your brand or specific SKUs if a vendor manager acknowledges your transition (especially if Amazon itself initiated your move). (b) Request approval through Seller Central.

Sometimes Amazon might ask for documentation to allow you to sell a product (like proof of authenticity or a brand authorisation letter). As the brand owner, providing these can clear certain restrictions. (c) Use alternative strategies if needed. In extreme cases, some brands have created new listings (new UPCs or slightly different product bundles) to get around a legacy gating issue – essentially treating it as a new product in 3P. Others have partnered with a trusted third-party seller temporarily to list the product and then transferred the listing to their own account later. These workarounds can be complex, so it’s better to avoid the issue if possible by clearing the gating with Amazon directly. The key takeaway is not to get caught with all your inventory tied up in Vendor Central only to find you can’t sell it on 3P. Do small-scale trial runs if possible, and avoid selling the exact same ASIN on 1P and 3P simultaneously – that scenario can confuse Amazon’s catalogue and create Buy Box conflicts (and Amazon might suppress one of the offers). It’s usually best to fully transition an ASIN from 1P to 3P in a controlled manner, or at least segment by SKU (some SKUs 1P, different SKUs 3P) during any interim hybrid period.

⚙️ Operational Load and Learning Curve: On Vendor Central, you got to offload a ton of operational tasks to Amazon – picking, packing, and shipping individual orders, handling customer service inquiries and refunds, managing returns, etc. As a 3P seller, all those responsibilities shift to you or your partners. This is arguably the biggest change in going 3P, and it requires a shift in mindset and resources. Forecasting and inventory management become your responsibility: you must decide how much stock to send to FBA, when to replenish it, and you need to keep a close eye so you don’t stock out (losing sales and rank) or overstock (incurring hefty storage fees). You’ll need proficiency in Amazon’s shipment creation workflow, or use integrator software to help plan and send inventory. If you choose to fulfill some or all orders yourself (FBM), you’ll need a reliable process and team for that too, including handling customer orders promptly and meeting Amazon’s strict shipping performance metrics.

Moreover, Seller Central’s interface and processes differ from Vendor Central’s. There’s a learning curve for your team. You’ll encounter flat-file templates for bulk listing updates, error codes that need deciphering when listings have issues, and a new set of performance metrics to monitor (Order Defect Rate, Valid Tracking Rate, Late Shipment Rate, etc.). Zack Rubin notes that historically,

“Seller [Central] has been more difficult [than Vendor] because you have to get more familiar with flat-file uploads… there’s just a lot more that goes on,”

highlighting that day-to-day account management on 3P is hands-on. In short, there’s a whole new world of Amazon operations and best practices to master.

Solution: Invest in training or talent. If you’re an agency guiding a client, ensure your team has Seller Central specialists who know the ropes. If you’re a brand going it alone, consider hiring experienced Amazon marketplace managers or engaging an agency/consultant to help navigate the initial transition. Also, document new standard operating procedures (SOPs) for the tasks that Amazon used to handle. For example, determine how you will process returned products (will they come back to your warehouse or be disposed/donated by Amazon?), and who on your team will be responsible for monitoring account health and customer messages daily.

The operational workload can be managed, but only with preparation and the right expertise. This transition is a chance to build new capabilities in-house, but it can be intense. One industry observer noted that shifting to 3P “requires new expertise, operational changes, and strategic adjustments” for brands used to 1P(amplifyy.com) – it truly is a new business model. Give yourself and your team time to learn, and don’t hesitate to get expert help for the first few months if needed. Remember, protecting your Amazon account health during this learning phase is crucial, so you want knowledgeable people involved from the start.

🏷️ Pricing and Distribution Challenges: When you leave Vendor Central, one safety net disappears: Amazon is no longer there to automatically price-match and chase away other sellers on your ASIN. In the 1P model, if some grey-market seller undercut your price, Amazon Retail would often just drop its own price to win the Buy Box (hurting your margins, but keeping the customer price low and consistent). In a 3P scenario, you are the one competing for the Buy Box. If other sellers have obtained your product (through unauthorised distribution, old inventory, liquidation, etc.) and they offer it for less, they can win the sale over you. This means any existing distribution leaks in your channel will become painfully visible once you’re a seller. Many vendors are surprised to discover there were a dozen other sellers lurking on their listings once Amazon Retail isn’t suppressing them.

Additionally, you now have to take charge of price parity and brand protection in the marketplace. If you want to maintain a premium price on Amazon, you’ll need to enforce that across your other channels; otherwise, third-party resellers might undercut you online. If you have a MAP (Minimum Advertised Price) policy, now is the time to double down on enforcing it. If you don’t have one, consider implementing one before the transition.

Solution: Tighten up your distribution and MAP enforcement well in advance of moving to 3P. Communicate with any distributors or wholesale partners about your Amazon strategy – ideally, restrict them from selling your products on Amazon at all (so you remain the only authorised seller). If that’s not feasible, ensure they adhere to your pricing policies strictly. Implement a formal MAP policy if you haven’t already, and make sure all reselling partners acknowledge it. Leverage Brand Registry on Amazon to monitor your listings. You may also choose to differentiate your Amazon offerings to make life harder for would-be resellers – for example, selling unique bundles, multi-packs, or Amazon-exclusive SKUs that others don’t have access to.

In one transition, Zack managed for a pet products brand, they introduced a strict MAP policy and began cleaning up unauthorised sellers on Amazon months in advance of the switch to 3P. By the time the brand itself was the sole seller of record, there were far fewer rogue sellers undercutting prices. It’s an ongoing effort – even with strong policies, you might still have to battle resellers who pop up – but having Brand Registry tools (for IP enforcement) and a legal strategy for unauthorised sellers will help tremendously. The goal is that when you launch as a 3P seller, you own the Buy Box for your listings nearly 100% of the time. That way, your marketing investments and pricing strategy won’t be undermined by others.

⌛ Timeline and Coordination: A common pitfall is underestimating how long a full 1P-to-3P transition takes and how carefully it must be choreographed. This isn’t a decision you execute in a week or even a month. From initial planning to the final switch-over, expect a 6–12 month project in most cases (depending on the number of SKUs and complexity of your business). Challenges include selling through existing Vendor Central inventory, timing the ramp-down of 1P purchase orders while ramping up 3P inventory, and aligning internal systems (like accounting and ERP) from a wholesale model to a direct-to-consumer model. If you simply stop fulfilling vendor POs one day and start listing on 3P without a plan, you could end up with stockouts or overstocks, confused customers, and a strained relationship with Amazon.

Solution: Project-manage the transition with cross-functional coordination. Treat this like a major product launch or system implementation. It often helps to create a transition task force or committee that includes stakeholders from supply chain/operations, finance, IT, sales, and marketing. Develop a detailed playbook or checklist – Zack recommends building a comprehensive task list – to track all the moving pieces. For example, you’ll need tasks for setting up the new seller account, tasks for operational changes (like new shipping processes, warehouse prep for FBA), tasks for financial changes (updating invoicing and revenue recognition), and so on. Set target dates for each phase of the transition and monitor progress.

Also, plan the inventory cutover carefully. One strategy is to phase the transition by groups of SKUs. You might start by intentionally not replenishing a specific product line on Vendor Central, allowing Amazon’s stock for those items to dwindle while you simultaneously build up inventory in FBA under your seller account. Communicate internally (and possibly to key partners or even customers, if necessary) about the planned change in how orders will be fulfilled to avoid surprises. During a transition period, it’s possible to run a hybrid model – some SKUs still 1P, others now 3P – but avoid having the same SKU being sold by both you and Amazon at the same time. That can confuse Amazon’s systems (and customers) and lead to pricing conflicts or listing suppression.

Some brands manage to negotiate a formal “wind-down” with their Amazon vendor manager – for instance, Amazon agrees to stop sending POs for certain SKUs after a given date. If you have that relationship, it’s worth a conversation. If not, you may have to handle it unilaterally: for example, by consistently declining POs for a specific SKU for several weeks so that Amazon’s system stops trying to reorder it. (Amazon’s automated ordering might make a few attempts on a popular item out of habit, but after a few rejections, it typically gets the message.) Patience and persistence are key here; you might feel like you’re playing whack-a-mole until every last SKU is transitioned, but it will end.

Despite these challenges, remember that thousands of brands have successfully made the switch to 3P. The process can actually strengthen your organisation in the long run.

“You’ll never be more connected with your operations team than during a transition,”

Zack shared, reflecting on past projects. Indeed, the journey forces different departments (finance, ops, marketing, IT) to work together closely on a common goal – ultimately making your company more agile and data-driven. In the next section, we’ll lay out a step-by-step game plan to execute the move effectively, pulling together the solutions we’ve discussed.

How to Execute a Successful 1P-to-3P Transition: A Step-by-Step Plan

So you’ve weighed the pros and cons and decided to take the plunge (or perhaps Amazon’s policy changes in late 2024 have forced your hand). How do you actually execute a vendor-to-seller transition with minimal disruption? Here’s a structured approach:

Plan and Analyse Upfront (3–6 Months Before Transition)

• Perform a Full SKU Audit: Begin with a thorough analysis of every product in your catalogue. As discussed, run a SKU-level profit-and-loss calculation for the 3P scenario. Calculate the expected FBA fees and Amazon commission for each product, then compare the net revenue per unit to what you were getting via 1P. Identify which SKUs would gain margin, which might lose margin, and which might need adjustments (like a higher price or different pack size) to be viable on 3P. This will effectively categorise your products into green light, yellow light, or red light for the transition. Decide if you will drop or modify any borderline products. 
  
  For example, if a particular item is not profitable on 3P at its current price, could you bundle two of them together and sell at a higher price point to make the fees more palatable? Or would it be better to exclude it from Amazon entirely? This audit guides your strategy. Zack quips that “you need to have enough green boxes in favour of the seller [3P] before making that change.” In other words, ensure that a substantial portion of your catalogue stands to benefit from the switch. If only a small handful of items look good for 3P, and the rest would suffer, you might reconsider or plan a more limited transition. Often, however, you’ll find many SKUs that look promising for 3P, and just a few that require special handling or should remain 1P.
  
  
• Secure Executive Buy-In & Build Your Team: A successful transition requires support and resources from the top. Make sure all stakeholders and executives understand the scale and significance of this project. Get explicit buy-in, since there may be short-term revenue recognition changes or costs (like investing in new hires or tools) that leadership needs to approve. Establish who will lead the project (identify a transition project manager or core team). Also, plan out who will manage the Seller Central account once you’re live. Do you have knowledgeable e-commerce staff who can take it on, or do you need to hire an Amazon specialist? 
  
  Perhaps you’ll partner with an agency or consultant for the first 6-12 months to guide you. If there are skill gaps on your team – say, nobody has experience creating FBA shipments or dealing with Amazon flat-file templates – decide how you will bridge those gaps (training existing team members, bringing in new talent, etc.). Early in the planning, line up any external partners you might use: for example, a 3PL (third-party logistics) provider if you plan to handle some orders via FBM, or an Amazon consulting firm to assist with account setup and troubleshooting. The goal is to have the right people and partners in place before you start flipping switches.
  
  
• Engage Amazon (if possible): If you have an assigned Vendor Manager or any Amazon contacts, consider looping them in once your plan is taking shape. Approach this carefully – if the relationship is good, explaining your strategy might lead to their support or at least cooperation. (For example, they might help ensure your brand isn’t gated on the 3P side, or give you advice on timing the transition to avoid penalties or stock issues.) Be sure to clarify any contractual questions: most standard vendor agreements don’t forbid selling via other channels, but if you’re in any exclusive programs, verify that you’re not breaching terms by going 3P. 
  
  In some cases, Amazon may even be relieved if you transition (for instance, if your vendor account wasn’t very profitable for them). Regardless, it’s valuable to know where you stand. If Amazon is receptive, you might coordinate on a plan to wind down 1P: e.g. Amazon agrees to stop ordering certain SKUs at a certain time. If they’re not receptive (or you don’t have a personal contact), don’t worry – you can still proceed, just more unilaterally. The key is to avoid surprises: you don’t want to suddenly stop fulfilling POs and have Amazon wonder what’s going on. Either communicate your plan or execute it in a way that naturally tapers off the 1P relationship.

Set Up Your Seller Central Account and Infrastructure

• Create the Seller Account and Enroll in Brand Registry: If you haven’t already, create a Professional Seller account on Amazon Seller Central well ahead of your target transition date. The registration and verification process can take days or even weeks (Amazon might require documents, interviews, etc., especially for a brand owner account). Use a unique email (separate from your Vendor Central login) for this account to avoid any internal conflicts. Once your Seller Central account is active, enroll your brand in Amazon Brand Registry. This step is crucial – Brand Registry verifies you as the brand owner (you’ll need a registered trademark) and gives you access to enhanced content, brand protections, and marketing tools. It also designates you as the authoritative voice for your listings, which will help in controlling content and fending off listing hijackers or incorrect contributions.
  
  
• Recreate Product Listings on Seller Central: Start building out your product listings in the new Seller Central account as early as possible. You don’t have to make them live for customers right away – you can create the listings in “draft” or inactive status. If your products already exist on Amazon (from your 1P days), you’ll be linking your seller offer to those existing ASINs. However, by enrolling in Brand Registry and listing the products yourself, you’ll ideally become the content owner, meaning you can update titles, bullets, images, etc., and have those changes stick. Use this opportunity to optimise your listings like never before. 
  
  Update your titles with strong keywords, rewrite bullet points to be more compelling, ensure your images are high-resolution and informative, and add A+ Content (Enhanced Brand Content) if you haven’t already. Think of it as relaunching your products with the best foot forward. The beauty of Seller Central is that changes can often be seen within minutes or hours, so you can iterate if needed. Many vendors find this freedom refreshing – for example, you can quickly add a new product variation or correct a typo without opening a case and waiting weeks. Before going live, double-check that each listing is complete (all relevant info filled out) and that it matches the Amazon catalogue data correctly (so you don’t accidentally create duplicate ASINs).
  
  
• Test for Gating or Listing Errors: As mentioned in the challenges section, you want to catch any Amazon-imposed restrictions early. Once your listings are created in Seller Central, do a small trial: pick one or two products and set their status to active (for sale) very briefly. You don’t need to actually have inventory available yet – this is just to see if Amazon throws any immediate errors or warnings. If you see messages like “This product is restricted” or “You need approval to list this brand/product,” then you know there’s gating in place. 
  
  To resolve it, you might contact Seller Support or the Catalogue team with proof that you are the brand owner (often an invoice or a letter of authorisation on your letterhead can do the trick via Brand Registry support). If the issue is that Amazon still has the ASIN tied up in Vendor-only status, you may need to coordinate timing (i.e. Amazon might only release it once they run out, etc.). In the worst-case scenario, you could decide to create a new ASIN – for example, if Amazon won’t let you list widget ABC, you might launch widget ABC as a 2-pack with a new barcode, thereby creating a fresh listing only you sell. This isn’t ideal, but it’s an option if gating proves stubborn for certain products. The main point is to identify these hurdles in advance so you’re not scrambling during the transition.
  
  
• Prepare Backend Systems: Reconfigure your internal systems and processes for a direct-selling model. This step is often overlooked, but it’s critical for a smooth transition. Work with your finance team to determine how revenue recognition will change – instead of invoicing Amazon for bulk POs, you’ll be recording individual customer sales (and Amazon will deposit funds into your account after fees). Ensure your accounting software or ERP can import Amazon settlement reports, or set up a process to do monthly reconciliations of Amazon payouts. Adjust your inventory management systems: inventory in Amazon FBA is still your inventory (consignment) until it sells, so track it as such. You’ll receive reports from Amazon on inbound shipments received, stock on hand, and so forth – make sure someone is tasked with reconciling those with your own records. 
  
  If you use any integrations or middleware (like EDI systems for 1P, or inventory/order management software for 3P), get those connections in place now. For example, you might implement an order management system that pools orders from Amazon and any other channels you sell on, to streamline fulfillment and customer service. Another consideration is tax and compliance: as a 3P seller, you might need to handle sales tax collection depending on the marketplace facilitator laws (Amazon collects in many states, but you should confirm your responsibilities) and possibly product compliance documentation that Amazon might have handled as a vendor. Essentially, walk through the entire flow of an order (from when a customer clicks “Buy” on Amazon to how it gets fulfilled and recorded in your books) and ensure every step is accounted for in your systems and team responsibilities. Zack has noted in webinars that finance teams need to understand how FBA inventory and payments work, because it’s a different paradigm from getting a PO and booking revenue upon shipment. Getting your backend ready will prevent chaos once orders start flowing.

Gradually Shift Inventory and Manage the Cutover

• Ramp Down 1P Purchase Orders: As you approach the transition, you’ll need to strategically reduce and stop sending inventory via Vendor Central. There are a couple of approaches here. One approach is to set a firm date after which you will no longer accept any new POs from Amazon; you’d communicate (or signal) that and stick to it. Another approach is to do it by product segments in waves. For example, you might first transition one category or brand line at a time. Identify a subset of SKUs that you plan to move in the first wave – perhaps your smaller items, or conversely, your best-sellers to get them under your control first. 
  
  Allow Amazon to sell through the inventory it has on those SKUs. You can stop replenishing by either not responding to POs (hard reject them in the vendor system) or marking those items as “temporarily unavailable” or “discontinued” on your Vendor Central side so Amazon doesn’t expect more. Amazon’s systems might still generate POs for a week or two, but if you consistently reject them, Amazon will eventually stop reordering those items. (Based on anecdotal reports, after 2–3 cycles of unfulfilled POs, Amazon’s algorithms flag the item and reduce or cease ordering.) 
  
  During this wind-down period for a SKU, monitor Amazon’s stock levels – you might coordinate so that you don’t leave them with stockouts that upset customers. Some brands choose to fulfill any residual customer orders via the Dropship (Direct Fulfillment) program if they were enrolled, which allows you to fulfill Amazon’s orders directly to the customer without Amazon holding inventory. This can be a softer way to not send bulk inventory, but also not cancel customer orders that Amazon might take. In any case, the idea is to gracefully exit 1P for that SKU: stop feeding it new stock and let whatever’s there sell out.
  
  
• Send Stock to FBA and Go Live on 3P: As Amazon’s inventory for a given SKU runs down to zero (or your cutoff date arrives), you should have already prepared FBA stock for your Seller Central account to take over. Time the inbound shipment of your inventory such that your units arrive and are checked in at Amazon fulfillment centres around when Amazon Retail is running out. This timing is crucial to avoid any gap where the product is completely unavailable to customers. As soon as your FBA inventory is ready and the Vendor offer is gone or suppressed, you can activate your 3P listing for that SKU. This might simply mean toggling it from inactive to live, or updating the price/quantity to show stock. 
  
  Keep a close eye on the listing once you go live. In the ideal scenario, customers won’t notice much difference except the seller name – your offer will win the Buy Box, and orders will start coming to you. If there are other third-party sellers on the listing, you might initially have to price competitively to ensure you win the Buy Box (since Amazon Retail is no longer there to dominate it). Typically, as the brand owner with FBA, you will have a buy box advantage, but price and seller performance still factor in. Once everything looks good, you’ve officially taken over that product’s sales on Amazon. Now, repeat this process in batches for your remaining SKUs, in whatever order you planned (by category, region, priority, etc.), until you’ve transitioned all intended products to 3P. During this period, you may be running a mix of vendor and seller – that’s fine as long as each SKU is clearly either in one model or the other.
  
  
• Monitor Performance and Adjust: The first few weeks of selling on 3P are a critical time to monitor and fine-tune. Your Seller Central account will start accumulating performance stats – keep them healthy. Watch metrics like Order Defect Rate (ODR), which includes any negative feedback, A-to-Z claims, or credit card chargebacks. An ODR above 1% can put your account in jeopardy, so address any issues immediately (e.g., if a customer complains about an item, work to resolve it and request feedback removal if appropriate). If you fulfill via FBA, a lot of these metrics are taken care of by Amazon’s logistics, but if you have any FBM orders, make sure you ship on time and upload tracking. 
  
  Also, track your inventory levels and sell-through rates. You might discover that some products sell faster than expected once you’re in control of pricing – be ready to send additional stock to FBA to avoid stockouts. Conversely, if something isn’t moving as quickly as you thought (maybe Amazon Retail was discounting it more than you are), you might need to adjust your pricing or advertising to boost demand, or remove some inventory to save on storage fees. Keep an eye on pricing across channels too – ensure no other seller is undercutting you significantly. Another crucial aspect is cash flow: as a vendor, you were used to getting paid by Amazon on terms (say Net 30 or Net 60 after invoice). 
  
  Now Amazon will pay you every 2 weeks (or you can request disbursements more frequently, but essentially it’s a continuous flow). While this is generally positive for cash flow (you get money faster after a sale), the change in payment schedule and the fact that Amazon holds a rolling reserve in some cases mean you should confirm your finance team has adjusted projections accordingly. Finally, solicit customer feedback – early reviews on your listings (now that you own them) are invaluable. You might use the Request a Review button or automate feedback requests to generate fresh reviews, especially if the listing was previously under Amazon and not getting many.

Post-Transition Optimisation and Growth

• Leverage 3P-Only Tools: Now that you are fully operating as a 3P seller, take full advantage of the tools and programs available to brand owners on Amazon. Many of these were off-limits or less accessible in Vendor Central. For instance, set up Amazon Coupons for some of your products – these provide a visible coupon badge on your listings and can entice customers to try your brand. Run Lightning Deals or 7-day Deals during high-traffic periods to spike sales (a tactic that also can improve your organic ranking through increased sales velocity). Consider enrolling eligible products in Subscribe & Save to encourage repeat purchases if you sell a consumable or regularly re-purchased item; as the seller, you can manage the discount and see metrics on subscription behaviour. 
  
  With Brand Registry, you also have access to Brand Analytics data – use the Search Terms report to discover what keywords shoppers use to find your products, and use those insights to refine your advertising and content (this data was not available to vendors by default). You can create an Amazon Storefront for your brand if you haven’t already – a multi-page branded experience that you can drive traffic to from Sponsored Brands ads or external marketing. Another unique set of tools for 3P brand owners are the Customer Engagement features: Amazon now allows brands to post content (similar to social media posts) that followers can see, and even send direct emails (within Amazon’s system) to customers who follow your brand with announcements of new products or promotions. 
  
  This is a nascent feature, but it’s worth building up a follower count: mention your Amazon Store URL on your website or social media and encourage fans to follow you on Amazon for exclusive updates. Over time, you’ll have a marketing channel you can tap into for product launches or holiday pushes. All in all, immerse yourself in Seller Central’s brand-centric tools – they can significantly amplify your presence now that you’re the one in the driver’s seat executing marketing strategies.
  
  
• Maintain Strong Customer Service: One hallmark of a successful 3P brand on Amazon is excellent customer service and responsiveness. Now that you’re interfacing with buyers directly (Amazon will forward customer messages to you, and you’ll see and manage returns/refunds), make customer support a priority. Monitor your buyer messages inbox daily and respond quickly (Amazon expects a response within 24 hours, even on weekends, to all customer inquiries). A prompt, helpful reply can prevent negative feedback or an A-to-Z claim. 
  
  Likewise, keep an eye on your product reviews and the Q&A section on your listings. Although you can’t directly remove negative reviews (unless they violate guidelines), you can comment on reviews as the brand, addressing any issues. For example, if someone leaves a 2-star review due to receiving a damaged item, you can reply to apologise and offer to make it right. In some cases, Amazon’s policies allow you to reach out to customers who left a negative review (through the “Contact Customer” feature in Brand Dashboard for certain review situations) to offer assistance or a replacement. 
  
  Use these capabilities judiciously – the goal is to turn unhappy customers into satisfied ones. This level of hands-on service was impossible as a 1P vendor (Amazon owned the customer relationship, and you never knew of issues until reading reviews after the fact). Now it’s on you, and done well, it’s a competitive advantage. Zack’s earlier example of turning a one-star situation into a five-star review through proactive service is a perfect illustration: if you sell a premium product and something goes wrong, a personalised apology, a quick replacement shipment, or even a bonus freebie can leave a lasting positive impression. Not only might that customer update or retract their negative review, but they’re more likely to buy from you again. Amazon rewards good customer experience indirectly, too – better reviews and account health metrics will improve your performance in the long run.
  
  
• Reevaluate and Refine Pricing/Margins: After a full sales cycle or two on 3P (say, a few months of data), take time to re-run your numbers and see how reality compares to your initial projections. You now have actual FBA fee costs, storage fee charges, return rates, advertising spend, etc., to incorporate. It may be worthwhile to create a fresh SKU-level P&L with the real data. You might find, for example, that some products incurred higher storage fees than expected because they sold slower – armed with that info, you can make a plan to either speed up sales (through promotions/ads) or reduce on-hand inventory for those items. 
  
  Or perhaps you discover that by slightly reducing the dimensions of a product’s packaging, you could drop it into a cheaper FBA fee tier – that kind of change can significantly improve margins at scale. Maybe your initial pricing was too conservative, and you’re consistently selling out – that could be a sign you can raise prices a bit and still maintain volume, thereby increasing profit. Conversely, if sales are slow, you might experiment with lower prices or greater advertising investment to kickstart the flywheel of sales and reviews. The key in this post-transition phase is continuous improvement. The 3P model gives you the flexibility to test and iterate on all these variables (pricing, packaging, advertising, and inventory levels) quickly. 
  
  Set aside time each month or quarter to review both top-line and bottom-line performance by SKU. Retire or fix any 3P listings that aren’t working out – just because you moved everything to 3P doesn’t mean you must keep every single item active if it’s unprofitable or causing headaches. You could choose to keep a problematic item off Amazon, or wait and see if Amazon invites it back to Vendor in the future for a limited arrangement. On the flip side, double down on the winners: if certain products are thriving with higher margins, think about expanding your catalogue with similar items or pushing those even more with ads. Your business is now very much like running your own direct-to-consumer operation, with a need to stay agile and financially disciplined.
  
  

Case Study Example: To illustrate how these steps come together, Zack Rubin shared a story of a pet products brand that executed a successful 1P-to-3P transition. They spent about six months in meticulous planning, mapping out every process internally (a complete end-to-end review of how orders, fulfillment, and finances flow). They proactively tightened up their distribution: months before the switch, they implemented a strict MAP policy and aggressively cut off unauthorised sellers, so that the playing field on Amazon would be clean when they went 3P.

They even re-engineered some of their product packaging ahead of time to better fit Amazon’s FBA sizing and weight tiers (avoiding higher fees). The transition itself was done in phases: they first moved one brand line over to 3P while maintaining others on 1P, then gradually expanded the 3P scope. During this period, their operations team and Amazon specialists worked hand-in-hand – it was “all hands on deck” to ensure inventory was in the right place at the right time and listings were perfectly tuned. There were challenges, of course: the team had to get used to Amazon’s listing flat files and the faster pace of customer interactions, and the warehouse had to adjust to sending many smaller shipments to FBA instead of big bulk pallets to Amazon.

But overall, the switch went smoothly with no major stockouts or account health issues. Post-transition, the brand found that on many of their products, they were achieving higher margins per sale than before, and they loved having direct access to their Amazon customers’ feedback. Additionally, the process of transition had a side benefit: it forged much closer collaboration between their departments. Zack noted it was

“painful at times, but great for connectivity across the org.”

This case underscores that thorough preparation and strong cross-team communication are the secret sauce in a successful 1P-to-3P conversion. The company emerged more profitable and more resilient, which made the growing pains worthwhile.

By following a structured plan like the one above, you can set your brand up to reap the benefits of the 3P model while minimising disruption along the way. It’s worth reiterating: take your time and do it right. Rushing a transition can result in avoidable stockouts, lost sales momentum, or account suspensions due to rookie mistakes. Many brands intentionally use a phased or hybrid approach over several quarters to make the change more manageable. In fact, you might choose to remain hybrid (some 1P, some 3P) indefinitely if that suits your strategy – there’s no rule that it must be all or nothing. The key is, after going through this process, you’ll have the flexibility to choose the model that best fits each product and situation. Now that we’ve covered the operational game plan, let’s talk about how to thrive in your new status as a 3P seller, particularly when it comes to marketing and growth.

Marketing and Advertising in Your New 3P World

A big part of reframing your Amazon strategy as a 3P seller is taking full ownership of marketing and advertising. Without Amazon Retail automatically promoting your products or running programs like Vine on your behalf, it’s now up to you to drive traffic and conversion. The good news is, Seller Central gives you an expansive suite of tools to do so – often more robust and flexible than what Vendor Central provided. Here are some key strategies to accelerate your growth in the 3P world:

Optimise Listings for SEO

Ensure that your product listings are fully optimised for Amazon’s search algorithm (A9/A10). This involves doing thorough keyword research and continuously refining your content. Start by identifying the primary keywords customers use to find products like yours – you can use Amazon’s Search Query Performance report (available in Brand Analytics) or third-party tools to gather these insights. Incorporate these keywords naturally into your product titles, bullet points, and backend search term fields.

For example, if you were selling an organic dog shampoo and you know “natural dog shampoo for sensitive skin” is a popular search, make sure phrases like that appear in your content. Beyond keywords, focus on conversion optimisation too: make your titles clear and compelling, ensure the main image is high quality, and highlight unique value propositions in the bullets (e.g. “Sulphate-free, vet recommended formula”). As a seller, you can update and test changes rapidly – take advantage of that agility. If you suspect a different title format could improve click-through rate, try it and monitor the impact on traffic. If you want to test a new main image, you can even use the Manage Your Experiments tool (if eligible) to A/B test it.

Regularly review your listings for opportunities: could you add a coupon badge to make the offer look more attractive? Is your description utilising all the space to tell your brand story (especially now that many shoppers will see the A+ Content on your listing)? The combination of SEO and conversion optimisation will drive your success in organic rankings. Small tweaks – like adjusting phrasing or adding an infrequent but relevant keyword – can yield significant gains in discoverability. Make it a practice to revisit your keyword strategy every couple of months, as trends and customer search behaviour can change, and your listings should evolve accordingly.

Master Amazon Advertising

To truly succeed as a 3P seller, you’ll want to become proficient with Amazon’s advertising platform. Sponsored ads are one of the most powerful levers you now control directly (whereas, as a vendor, you might have relied on Amazon’s AMS or had limited access through agencies). Start with Sponsored Products, which are the ads that appear in search results and on product pages, looking like regular listings. These operate on a pay-per-click auction system. A good initial strategy is to run campaigns targeting your own brand keywords (to defend your turf against competitors’ ads) and category keywords where your product is relevant. Because you now earn the full retail margin, you may find you can invest more aggressively in PPC while still remaining profitable.

Also explore Sponsored Brands (formerly Headline Search Ads) – these can showcase a custom headline and multiple products or a video, and they link to your Storefront or a curated landing page. Sponsored Brands are great for building brand awareness and cross-selling your lineup. If you have video assets, the Sponsored Brands Video ad format tends to have high engagement and can set you apart. Sponsored Display ads can retarget shoppers who viewed your product or similar items and show ads on Amazon’s home page, product detail pages, or even off Amazon – these are useful once you have decent traffic and want to re-engage those audiences. Over time, you might even consider the Amazon DSP (Demand-Side Platform) for more advanced audience targeting off Amazon, but that usually comes later and requires a larger budget or working with Amazon Ads reps.

As you ramp up ads, continually measure and optimise. Track your Advertising Cost of Sales (ACoS) or the newer metric, ROAS (Return on Ad Spend), to ensure your campaigns are delivering within acceptable ranges. Keep in mind your 3P margins when setting these targets – for instance, if your margin per sale is 30%, you might aim for an ACoS of 20% to stay well in the black, whereas as a vendor, you might have looked at it differently due to the wholesale pricing. Use the reports Amazon provides: Search term reports will show which user search queries led to clicks and sales, which is gold for refining your keyword lists.

You might discover new long-tail keywords converting that you hadn’t included in your content – add them to your listing or target them in campaigns. Similarly, see which ASINs appear in your Sponsored Display or Product Targeting campaigns as converters – maybe there are competitor products whose customers love yours when they see it; this could inform future product development or targeting strategy.

The key advice is: treat advertising as an ongoing process, not a set-and-forget. Amazon’s ad ecosystem is dynamic, and competitors will be adjusting their bids and tactics too. Regularly optimise your bids (raise on high performers, lower or pause on poor performers), try new ad types (e.g. if you haven’t done Sponsored Brands Video, give it a shot), and adjust budgets around seasonality or special events (like Prime Day, holiday season, etc., when traffic spikes). As a 3P seller, you have complete control and a direct incentive to make ads drive your growth, so dive in wholeheartedly.

Leverage Promotions and Build Loyalty

Beyond paid advertising, Amazon’s Seller Central offers a variety of promotional tools that you can use to drive sales and encourage customer loyalty. Experiment with these to see what resonates with your target audience. For example, setting up a ** percentage-off promotion** (like “Buy 2, get 10% off”) can be a great way to increase basket size if you have complementary products or variants. These promotions show up on your listings and can entice customers to purchase more than one item. Likewise, Coupons (the little green badge coupons on Amazon) are very popular with deal-seekers; even a small discount can increase click-through and conversion rates because customers perceive they’re getting a special deal. Watch the redemption rates and performance of coupons – you can set them up for a limited time and budget, and see how they impact your sales velocity.

For products that lend themselves to repeat purchases (consumables, supplements, beauty products, pet supplies, etc.), Subscribe & Save is a powerful program. As a 3P seller, you can enroll in Subscribe & Save and set a base discount (usually 5% for the customer, or more if they have many subscriptions). Amazon handles the subscription management and gives subscribers a convenient schedule for reorders. The benefit for you is a higher lifetime value per customer and more predictable recurring sales. Plus, Subscribe & Save subscriptions often lead to a higher placement in search for those products (Amazon knows subscribers are more valuable). Just be sure you can keep subscribed items in stock, since those customers expect their deliveries on a set schedule.

Don’t forget about Amazon’s newer features to foster brand loyalty. One of these is the Follow button on your Amazon Store and listings (visible to shoppers as “Follow [Brand]”). Encourage people to follow your brand on Amazon by creating compelling Storefront content and even mentioning in your product inserts or social media that they can follow you for updates. Why? Because with enough followers, you can utilise the Customer Engagement tool in Seller Central to send out emails (crafted by you, but sent by Amazon) to your follower base, announcing new product launches or promotions.

This is essentially Amazon giving brands a mini-CRM capability within certain limits. It’s a free way to re-market to customers who have shown interest. Similarly, use Amazon Posts (if available in your market/category) – these are like shoppable social media posts that appear on the Amazon mobile app, on your Store, and on product detail pages. It’s another way to get eyeballs on your brand and build a lifestyle around your products. All these promotional and loyalty-building tactics can help drive repeat sales and word-of-mouth, which improve your brand’s stability in the marketplace.

Use Analytics for Continuous Improvement

With great power (over your business) comes great responsibility to analyse your results. Now that you have far more data at your fingertips, make it a habit to dive into it and extract insights. Your everyday dashboard is the Business Reports in Seller Central (found under Reports > Business Reports). Here you can see sales and traffic by ASIN, which is incredibly useful. Monitor metrics like Unit Session Percentage (conversion rate) and Sessions (visitors) for each product. If you notice the conversion rate dropping on a product, investigate why – maybe a recent review or rating dip is scaring customers, or a competitor lowered their price.

If traffic is low, perhaps your ads need tweaking or your SEO could be improved. Another useful set of reports is under Brand Analytics (for brand-registered sellers): you can see things like the top search terms that led to your product and how you rank for them, demographic info about your customers, and even which other products are most commonly bought alongside yours. These data can guide strategic decisions – for instance, if Brand Analytics shows that customers who buy your product often also buy another complementary item, maybe you should consider bundling them or creating a variation.

Also, pay attention to the economics: Amazon provides a Fee Preview report and periodic inventory reports, which help ensure you know the fee tier for each product (so there are no surprises). Check your advertising reports to understand ACoS and true advertising cost as a percentage of sales; ensure your campaigns are yielding a good return relative to your now-higher margins. Over time, you might shift from thinking about ACoS to thinking about total TACoS (Total Advertising Cost of Sales, i.e., ad spend as a percentage of total sales) to see if your organic sales are growing as a result of ad investments.

Don’t ignore qualitative data too. Read your reviews carefully – they can reveal product issues or new use cases. If multiple customers mention a feature request or a complaint, bring that feedback to your product development or sourcing team. Maybe there’s an easy fix or improvement that could be made, which you can then tout in your marketing. On Seller Central, you also have the Voice of the Customer dashboard, which aggregates returns and customer comments (for instance, reasons customers returned an item). Keep an eye on it; if you see a spike in returns or a common return reason, act fast to address it, either by clarifying something on your listing or improving quality control. After making improvements, you can even leverage your listing content to highlight them (e.g., “New and improved packaging as of 2025 to prevent leakage during transit!”).

In essence, adopt an iterative, data-driven mindset. One of the advantages of being a seller is you’re much closer to the action and feedback loop. The marketplace rewards those who stay active and fine-tune their approach. By continuously analysing your performance metrics and customer feedback, you’ll be able to react to market changes faster than ever and keep optimising for growth.

Stay Vigilant on Unauthorised Sellers

Even after a successful transition, the battle for control can continue if other sellers try to piggyback on your products. Despite your best efforts to clean up distribution, you might find down the road that a new seller has appeared on one of your listings. Perhaps a retailer had old inventory and decided to list it on Amazon, or someone in another country is importing your product and selling it. It could even be counterfeit if your brand is popular. As a brand owner 3P seller, you need to stay vigilant and police your listings regularly. Make it a routine to check the “Available from other sellers” section on your key ASINs. There are also third-party monitoring tools that can alert you when new sellers join your listings or if the Buy Box percentage for your offer drops below 100%.

If you do spot an unauthorised seller, investigate who they are and how they might be sourcing the product. If it’s clear that the product is counterfeit or not as described, you should immediately file a complaint through Amazon’s Brand Registry (e.g., a Trademark infringement or Counterfeit claim). Amazon takes IP complaints seriously, especially from brand owners, and this can result in the offending offers being removed. If the seller appears to be selling a genuine product (say, they have decent feedback and are moving units), then it becomes a business issue: how did they get the product? This might require an offline solution – contacting your distributors or checking if any partner is diverting goods. You may need to send a cease-and-desist letter to the seller if they are violating your policies or agreements. In some cases, simply the presence of the brand as an active Amazon seller deters others (they realise you’re watching the store). But in other cases, you might have to resort to legal enforcement of MAP or distribution agreements.

Another approach is to outmaneuver resellers through product strategy. For instance, if you find unauthorised sellers are a recurring issue, you could introduce Amazon-specific bundles or kits that only you sell. A random reseller might have access to your single units, but they likely won’t have the custom 3-pack that you created exclusively for Amazon. By directing customers to these unique offerings (via ads or your Storefront), you can make the competition irrelevant. Also, utilise expansion of your catalogue to keep resellers guessing – if you frequently launch new variations or limited editions, you’ll always have some ASINs that are yours alone for a good period of time.

The reality is, controlling distribution is an ongoing battle in any channel, not just Amazon. But now that you’re 3P, you have more tools at your disposal to combat it. Keep your Brand Registry status in good standing (respond to any Amazon requests for proof promptly, such as if they need verification that you own the brand), and don’t hesitate to escalate repeat offenders to Amazon’s Marketplace Abuse teams if needed. Your aim should be to maintain as close to 100% Buy Box ownership on your branded products as possible. When you achieve that, you fully control the customer experience and pricing – which were the main reasons for switching to 3P in the first place.

Conclusion: Embrace the 3P Opportunity – and Plan for the Long Term

Transitioning from Amazon’s 1P vendor model to the 3P seller model is undoubtedly a challenging journey – but for many brands, it has become a pivotal step toward sustainable success on the platform. By taking on the role of a third-party seller, you gain the keys to your brand’s destiny on Amazon: control over pricing, the ability to directly shape your brand presence, richer data and insights, and the agility to adapt quickly to market changes. At the same time, we’ve seen that Amazon itself is moving in this direction, focusing its retail partnerships on only the largest brands and pushing everyone else toward the marketplace(amplifyy.com). In that context, making the switch isn’t just about your brand’s strategy – it’s aligning with Amazon’s evolving strategy as well.

None of this is to say the transition is easy. It requires careful planning, cross-functional coordination, and a willingness to learn a whole new ecosystem. There will be bumps along the way, but with a solid roadmap (like the one we’ve outlined), those bumps become manageable hurdles rather than roadblocks. The long-term payoff can be substantial: healthier margins, more control over your brand image and customer experience, and a direct relationship with your Amazon customers that simply wasn’t possible as a vendor.

To recap a few key takeaways: start with thorough analysis and preparation, get your leadership and team fully on board, and don’t rush the process – execute it methodically. Once you’ve made the move, lean into all the advantages of being a 3P seller: optimise your listings relentlessly, leverage every marketing tool available, and stay responsive to your customers and data. The first six months to a year will be a learning curve, but it will get easier as you build expertise and see the results.

Remember, you’re not alone in this shift. Hundreds of brands are undergoing the same evolution, especially in light of Amazon’s late-2024 Vendor Central shake-up. The silver lining is that Amazon’s third-party ecosystem in 2025 is more mature and supportive than ever. There’s a vast community of service providers, agencies, and fellow sellers who share knowledge on how to succeed. Amazon itself is providing better tools for brand owners (from Brand Analytics to streamlined seller support). In many ways, there’s never been a better time to be a brand selling on Amazon’s marketplace.

If you’re reading this and feeling both excited and a bit overwhelmed, that’s natural. Take it one step at a time. You might start by watching the full MerchantSpring webinar with Zack Rubin (if you haven’t already) to hear these insights straight from an expert who’s been through it – sometimes hearing real Q&A can spark ideas specific to your situation. Additionally, consider leveraging tools and expertise to ease the transition. For instance, MerchantSpring offers analytics solutions like a Vendor Profitability Tracker (to compare your 1P vs 3P performance) and a Retail Analytics Dashboard that can help you monitor sales and share across multiple channels as you change your model. Whether it’s these or others, the right technology can provide clarity and confidence as you make big changes.

Finally, as you embrace the 3P model, keep an eye on the road ahead. The e-commerce landscape will continue to evolve, and you now have the agility to evolve with it. Some brands may find a hybrid 1P/3P strategy is the best long-term solution – for example, remaining a 1P vendor for certain high-volume, low-margin items where Amazon’s logistics give an edge, while running 3P for the rest. Others might go all-in on 3P in their home market but use 1P for entering new international markets where Amazon offers vendor programs. The beauty of having gone through this transition is that you’ll have the experience and flexibility to choose what’s right for your business at each juncture. You’ve essentially added a powerful capability to your organisation by mastering 3P selling.

In closing, the 1P-to-3P switch is a bold move that can unlock tremendous opportunities if done thoughtfully. Embrace the challenge, equip yourself with knowledge and data, and go into it with a long-term perspective. Amazon’s marketplace rewards those who stay adaptive and customer-focused – and now, that’s completely in your hands. Here’s to your successful transition and the growth that comes with being in control of your Amazon destiny!
