For years the deal was simple: Amazon owned the storefront, and if you wanted its 200 million-plus Prime members, you rented shelf space inside Amazon’s world on Amazon’s terms. That deal is quietly being rewritten. Amazon is now pushing to place Prime shipping, delivery, and returns inside your website, under your brand, on your checkout. The badge sits on the merchant’s product page. The order confirmation carries the merchant’s name. The customer feels like they never left the brand. Behind the glass, Amazon’s fulfillment network moves the box.
This is Buy with Prime, and the strategic direction behind it is the real story. Amazon does not only want to be the store you shop at. It increasingly wants to be the plumbing every store runs on, whether or not shoppers ever notice. For multichannel brands whose direct-to-consumer site already outperforms their Amazon listings, that offer is tempting and loaded at the same time. The question every operator should be asking is not “does this lift conversion.” It is “whose infrastructure is my brand running on, and what leverage do I keep if I plug in.”
What Buy with Prime actually is right now
Strip away the framing and the mechanics are concrete. A merchant adds a Buy with Prime widget to its own e-commerce site. A Prime member sees the familiar Prime badge and delivery promise on the brand’s product page. When they buy, according to Amazon’s own description, “you’ll move on to the brand’s checkout page, which will be automatically populated with your preferred delivery address and default payment method from your Amazon account.” Amazon then, in its words, “handles the delivery and returns for Buy with Prime orders” through the same fulfillment network that powers Amazon.com, described by Amazon as “the world’s largest fulfillment network.”
The split is the point. The front end (the storefront, the checkout page, the brand experience) stays with the merchant. The back end (warehousing, pick and pack, delivery, returns) belongs to Amazon, running on Multi-Channel Fulfillment, the same Amazon logistics service brands already use to ship non-Amazon orders. Amazon lists Multi-Channel Fulfillment as the fulfillment layer merchants “rely on” to “streamline your order fulfillment and inventory management.” So the merchant keeps the face of the transaction. Amazon keeps the muscle underneath it.
Data sits in the middle, and this is where operators need to read carefully. Amazon does share transaction data back to the merchant. Per Amazon’s own explainer, “Amazon shares your name, email, delivery address, phone number, and the last four digits of your payment method used during checkout with the merchant.” That is meaningfully better than a marketplace sale, where the brand often gets almost nothing usable. But it is data Amazon passes through, not data the brand captured on its own rails. The distinction matters when we talk about leverage.
One correction on the popular version of this story. Some accounts describe Buy with Prime as working with no Amazon account at all, with membership checked silently in the background. We could not confirm that in Amazon’s current documentation, and we are not going to state it as fact. As the product is documented today, the flow uses the shopper’s Amazon account to populate checkout, and Amazon’s help center states there is no separate guest option inside the Buy with Prime path: a non-Prime shopper is either prompted to join or sent back to the brand’s own standard checkout. We flag it here because the honest read of the direction, invisible infrastructure, is strong enough on its own without overclaiming the mechanics.
Before you hand a channel to someone else’s infrastructure, know how it actually performs

Why Amazon wants to be invisible
For most of its history Amazon fought to be the destination. The homepage, the search bar, the buy box: that is where margin and control live. So why would Amazon volunteer to disappear behind another brand’s logo? Because the destination game has a ceiling, and the infrastructure game does not.
Amazon Web Services taught the company this lesson at planetary scale. AWS does not need you to visit Amazon. It just needs a cut of everything that runs. Buy with Prime and Multi-Channel Fulfillment are the retail version of the same idea. Amazon monetizes the shopping economy even when the shopping happens somewhere else, on a merchant’s own domain, under a merchant’s own brand. Every Buy with Prime order still runs through Amazon’s warehouses, Amazon’s delivery, Amazon’s returns, and Amazon’s fees.
The commercial case to merchants is conversion, and the figures are real but worth stating precisely so nobody rounds them up in a pitch deck. Amazon’s own consumer explainer states Buy with Prime “has been shown to increase shopper conversion by 20% on average.” Amazon’s Buy with Prime site separately reports that in A/B testing from July 2023 through June 2024, “brands experienced, on average, a 16% increase in revenue per visitor using Buy with Prime.” Trade coverage from Retail Dive, reporting the US expansion, cited a figure of roughly 25%. Three different metrics, three different numbers, all pointing the same way: the Prime badge and Prime delivery promise move the needle on someone else’s checkout. That is exactly why it is attractive, and exactly why it is worth reading the fine print.
The direction of travel got clearer in 2026. TechCrunch reported in March 2026 that Amazon was expanding a program letting customers shop from other retailers’ sites, and that “the program was being offered to a range of brands and wasn’t limited to partners using Buy with Prime.” Those orders, TechCrunch noted, land in the same “Your Orders” tab where shoppers track their Amazon purchases. The seed of that effort, per the same reporting, was a feature Amazon “began beta testing” in February 2025 that pointed shoppers to outside retailers when Amazon’s own results came up short. Read together, the pattern is unmistakable: Amazon is extending its reach past its own storefront and into the open web, keeping the Prime relationship and the fulfillment even as the storefront belongs to someone else.
What multichannel brands should weigh
This offer is aimed squarely at a specific operator: the multichannel brand whose direct site converts and retains better than its Amazon store, but who still wants Prime-grade delivery to stop bleeding conversions at checkout. If that is you, the upside is genuine. You keep your storefront, your branding, and a direct order relationship. You bolt on the one thing your DTC site usually cannot match: two-day, Prime-badged, trusted delivery that shoppers already believe in.
Keep your leverage: measure the channels you actually control
The whole lesson here is knowing whose infrastructure you depend on. On social commerce, the tools that show you competitor pricing, top products, and creator performance are FastMoss and Kalodata.

Now the leverage question, which is the part a conversion chart will never show you. When Amazon runs your fulfillment, your delivery, and your returns, Amazon controls the cost structure and the switching cost of the most operationally painful part of your business. The data you receive is real but it is passed to you, not captured by you. The delivery promise your customers now expect is Amazon’s promise, not yours. If fees change, if terms change, if the program’s priorities change, the brand that leaned all the way in has the least room to move. We have watched this movie in the marketplace, where sellers who built their entire demand engine on Amazon woke up to new fees and new rules with nowhere to go.
None of that makes Buy with Prime a trap. It makes it a decision with a hinge. The healthy posture is to treat Amazon’s fulfillment as one channel among several, not the spine of the whole operation. Keep a real, direct relationship with your customer: your own email list, your own retention flows, your own first-party data captured on your own checkout where you can. Keep at least one fulfillment path you own or can switch to. Use Prime-grade delivery to win the conversions you are losing today, while being clear-eyed that the delivery experience your customer falls in love with belongs to your infrastructure partner, not to you.
The framing to carry out of this is simple. Amazon is done insisting it be the front door. It is happy to be the pipes, the wiring, and the delivery vans behind a thousand brands that think they are independent. That can be a great deal, and for many multichannel sellers it will be. Just make the trade with your eyes open. Every capability you rent is a capability you no longer control. Before you plug Prime into your storefront, decide which parts of your business must stay yours, and hold that line.
