If you've spent more than five minutes at an ecommerce conference or scrolled through LinkedIn lately, you’ve likely seen the heated debate. On one side, you have the "1P is the only way to scale" crowd, and on the other, the "3P or death" evangelists. It’s a bit like watching people argue over whether a Subway is a sandwich. It’s passionate, slightly confusing, and usually misses the bigger picture.

The reality of the Amazon 1P vs 3P debate is that there isn't a single "right" answer that fits every business like a glove. If a guru tells you otherwise, they’re probably trying to sell you a course, or their services. The best model for your brand depends entirely on your specific circumstances, your internal capabilities, and your long-term goals. In this guide, we’re going to look at the landscape for 2026, help you weigh the pros and cons, and ensure you aren’t just following the crowd into a strategic dead end.

Before we dive into the strategy, let’s get our definitions straight. It’s easy to get lost in the jargon, but your choice of model dictates who owns the inventory, who sets the price, and who ultimately gets the blame when things go sideways.

This is the Vendor Central model. You act as a wholesaler, selling your products directly to Amazon. They become the "Merchant of Record," meaning they own the inventory, set the retail prices, and handle the shipping. It feels like a traditional retail relationship, but with way more algorithms and fewer human buyers to talk to.

This is the Seller Central model. You sell directly to the customer through Amazon’s marketplace. You own the inventory until the moment it’s sold. You set the prices, manage the listings, and decide whether to use Fulfillment by Amazon (FBA) or handle the shipping yourself. This offers the most control but requires the most "heavy lifting" in terms of daily management.

You might hear people talking about "2P" or "Accelerators." This is essentially a middle-ground approach where you sell your goods to a third party (not Amazon) who then lists them on the marketplace, via their own Vendor Central or Seller Central account. These partners often handle the marketing, listing optimisation, and inventory management for a slice of the pie. Often these partners seek exclusivity over your brand on the channel to ensure their success. It’s a great option for brands that want to manage their presence on the channel but don’t have the internal team to manage it.

This isn't really a strategy, but it’s where many brands find themselves. You don't sell to Amazon, and you don't sell on the marketplace yourself. Instead, you let distributors or random resellers own the channel. It’s the easiest path to losing control of your brand identity and your pricing.

You can’t make this decision based on "vibes" alone. You need to involve your finance partner early and often. The financial profile of a 1P business looks very different from a 3P business, and your P&L needs to reflect that.

When comparing Amazon Vendor vs Seller profitability, many brands find that while the 1P model offers higher volume with less "daily" work, the 3P model often yields higher net margins. Interestingly, as we head into 2026, the 3P model is actually becoming more cost-effective - Amazon recently announced some of its largest-ever fee reductions for 2026 across its European stores.

While they're pushing vendors toward the 3P model, they're also making that model significantly more attractive. We're talking about an average reduction of £0.15 or €0.17 per unit sold. In categories like clothing, pet supplies, and home products, the referral fee cuts are even more dramatic.

If you’re currently using a 2P solution, now is the time to renegotiate your terms. Ensure you’re both benefiting from the shifting fee structures and that your partner isn’t just pocketing the extra margin.

Deciding between models isn't just about what you want to do; it’s about what you can do. The Amazon hybrid model benefits are tempting—selling some items via 1P for volume and others via 3P for margin—but it requires a high level of operational maturity.

Giving away margin to third parties (like 2P partners or agencies as I wrote about here) needs to be weighed against the cost of hiring a full-time in-house team. Sometimes, paying a "success fee" to an expert is cheaper than the trial-and-error costs of doing it yourself.

Whether you choose 1P, 3P, or a hybrid approach, there is one thing you cannot outsource or ignore: your brand protection strategy. Moving from 1P to 3P doesn't magically fix a messy distribution network. If your products are leaking out from authorised distributors and showing up on the marketplace at a discount, your 3P sales will tank because you can't win the Buy Box. Meanwhile, if you're on 1P, Amazon will simply price match the lowest "grey market" seller, eroding your brand value and your margins simultaneously.

However, how you protect your brand depends heavily on where you are selling. You can't just copy-paste a US strategy into Europe and expect it to work without a visit from a very expensive lawyer.

If you try to enforce a MAP policy in the UK or EU, you're likely committing a "hardcore restriction" known as Resale Price Maintenance (RPM). European regulators are famously protective of price competition, and trying to fix a minimum price is a quick way to get a massive fine.

Instead of controlling the price, European brands must control the distribution. This is where a Selective Distribution Agreement (SDA) comes in.

Wherever you’re based, taking decisive control over your channel means cleaning up your distribution agreements to prevent leakage and using technology to track your inventory. Switching models won't save you if your "authorised" partners are the ones stabbing you in the back.

Without these basics, you’re just rearranging deck chairs on the Titanic. According to Amazon’s Brand Protection Report, the platform is getting better at removing counterfeits, but the burden of protecting your pricing and distribution still sits squarely on your shoulders.

As I shared in my very first article the word on the street is that plans are afoot to purge a large volume of European 1P Vendor Central accounts in 2026. We’ve seen the writing on the wall for a while now, following the European purges in 2023, where thousands of smaller vendors (primarily distributors) were told to move to Seller Central.

Amazon is increasingly focusing its 1P efforts on "must-have" brands and massive household names. For smaller or mid-market brands, Amazon is taking the decision out of your hands. They’d rather you take the inventory risk and management overhead of the 3P model. If your 1P purchase orders have been shrinking or your lead Vendor Manager hasn't answered an email since the last eclipse, you should start planning your move now. Waiting for the "we’re breaking up" email from Amazon is a recipe for a Q4 disaster.

If the vendor purge has you spooked, or if you’ve realised that 3P is the better play for your margins, you can't just flip a switch. Switching from 1P to 3P Amazon is a delicate dance. If you do it poorly, you'll end up with "out of stock" badges, lost search rankings, and a very grumpy finance department.

Success on Amazon isn't about top-line revenue; it's about what you keep. You need a deep understanding of Amazon unit economics for brands. This means knowing your landed cost, your FBA fees, your referral fees, and your advertising cost per unit (CPA).

If you’re outsourcing to a 2P or an agency, don't let them just report on "ROAS" (Return on Ad Spend). ROAS is a vanity metric if your per-unit profit is negative after all the hidden Amazon fees. You need to know that for every widget sold, you’re actually putting money in the bank. This is where the basics matter. No amount of "AI-powered bidding" can save a product with bad unit economics.

At the end of the day, none of these models; 1P, 3P, or 2P is a magic wand that guarantees success. The only true path to winning on Amazon is having a clear strategy and executing the basics flawlessly.

You need to:

Whether you’re a massive brand owner or a scrappy D2C startup, your Amazon presence should be a reflection of your overall business goals, not just a reaction to whatever the latest "guru" says on a podcast. Go in with your eyes open, run the numbers, and don't be afraid to pivot if the model you chose three years ago isn't serving you today.

What’s your current stance on the 1P vs 3P debate? Are you sticking with Vendor Central, or are you preparing for the 2026 shift? We’d love to hear about your experience and the challenges you’re facing in the current marketplace environment.
