Amazon Is Adding Walmart, Shopify, eBay and TikTok Shop to Seller Central

On September 24, 2026, Amazon started opening Seller Central to Walmart, eBay, Shopify and TikTok Shop. For a US brand already selling on two or three of those channels, it is a real change: one order screen for Amazon and the channels you connect, and fulfillment through Amazon in a few clicks. The tools are free; the fulfillment is not. Below: what works at launch, what is announced for later, what the announcement leaves out, and where your multichannel data ends up. Every Amazon fact carries its status and was checked on September 25, 2026.

What did Amazon announce on September 24, 2026?

Amazon announced multichannel selling tools in Seller Central (checked September 25, 2026) in a post by Mary Beth Westmoreland, its vice president of worldwide selling partner experience. Sellers can connect eBay, Shopify, TikTok and Walmart accounts to Seller Central, and Amazon promises more channels without naming them. Amazon's case is that more than 95% of independent sellers in its store already sell on several channels, each with its own dashboard, login and workflow. Marketplace Pulse reported the same day that the news came at Accelerate, Amazon's annual seller conference.

Status: rolling out (US). Amazon says the experience reaches sellers in the US store gradually over the coming months, at no additional cost, and that more capabilities and channels will follow. Amazon does not call it a beta, and it has not published an order or eligibility rules for the rollout.

The move builds on Amazon services for off-Amazon sales: Multi-Channel Fulfillment, Amazon Warehousing and Distribution, and Buy with Prime. Marketplace Pulse notes that Amazon announced MCF integrations with Walmart and Shein at last year's Accelerate. As it puts it, each of those steps handled goods or payments, and Amazon dropped out of the seller's workflow once an order shipped. The new tools put Amazon in front of the other channels instead of behind them.

The day before, on September 23, Amazon also announced Seller Assistant workflows and a selling partner plugin for Amazon Quick and Anthropic's Claude (checked September 25, 2026), which Amazon labels beta for sellers in its US stores. We cover it in Amazon's Seller Assistant plugin for Claude. The two moves run in opposite directions: the plugin carries your Amazon data out to other AI tools, while the multichannel tools pull your other channels' data into Amazon.

What can you see and do from Seller Central now?

Amazon describes the launch experience in one sentence: connect eBay, Shopify, TikTok and Walmart accounts, import and link off-Amazon listings, view multichannel sales and orders, and fulfill across channels in a few clicks. You start from the multichannel settings page in the Settings menu at the top right of Seller Central. Amazon's announcement says TikTok; Marketplace Pulse names the channel as TikTok Shop, where TikTok sales and orders happen.

Amazon's example is a seller of phone cases on Amazon, Shopify and Walmart. They open the Manage Orders page and see unshipped orders from every channel on one screen, with order details, customer information and fulfillment options. They select a Shopify order, click to fulfill it through Amazon, and tracking flows back to Shopify once the shipment is created. That is why the listing links matter: MCF ships from your FBA stock, so an outside order has to be tied to an Amazon SKU with stock before Amazon can fulfill it.

Amazon says the screen covers every order from every connected channel, whether or not Amazon ships it, so an order you ship from your own warehouse or a 3PL still shows up there. So the launch is more than a dashboard. It links listings, creates fulfillment orders and, in Amazon's Shopify example, writes tracking back to the channel the order came from.

Fulfilling through Amazon means Multi-Channel Fulfillment from your FBA inventory, and each channel keeps its own rules. For Walmart, Amazon's own guide to MCF for Walmart orders (checked September 25, 2026) says orders must ship in unbranded boxes with Amazon Logistics blocked, and that the standard 5% surcharge for blocking it is waived until January 14, 2027. eBay and TikTok Shop set their own shipping and tracking rules too, and our guide to multi-marketplace order routing compares how Walmart, eBay and Amazon measure late shipments.

What does it not cover yet?

Several features in the announcement are written in the future tense. Amazon says sellers "will be able to" edit a description once on the Manage Products page and have it reformatted for each channel, and generate channel-ready listing content with its AI tools. It says the tools "will give" sellers a profitability view that pulls in ad spend, traffic and sales from every connected channel, although the post quotes one seller who already compares channels in a profitability dashboard. None of the three is in Amazon's list of what is available today, and Amazon gives no date beyond saying more channels and capabilities are rolling out soon.

Other gaps are simply absent from Amazon's announcement. That does not mean they will never come; it means you should not plan around them yet.

• Other channels. Etsy, Target Plus, Temu, Wayfair and websites not built on Shopify are not in the first four. Amazon has not named the next ones.
• Stock quantities on other channels. Nothing in the announcement pushes available quantities from your warehouse or 3PL to Walmart, eBay, Shopify or TikTok Shop listings. Amazon's separate MCF and Buy with Prime app for Shopify (checked September 25, 2026) pushes FBA inventory levels to Shopify once SKUs are mapped; stock held anywhere else still needs its own sync. The same guide says Amazon will deactivate the older MCF: US Fulfillment app on September 30, 2026.
• Your own warehouse and 3PLs. Orders you ship yourself do appear on the screen, but the announcement describes fulfilling through Amazon, not choosing between your warehouse, several 3PLs and MCF by cost and ship-by date.
• ERP, accounting and pricing. There is no mention of ERP or accounting sync, per-channel price rules, returns, or customer messages on other channels.
• Outside the US. The rollout covers sellers in the US store.

What does Seller Central cover, and what does your own layer cover?

The table puts Amazon's tools, as announced on September 24, 2026, next to what a brand's own operations layer covers. "Rolling out (US)" means Amazon lists it as available today, reaching US accounts gradually. "Announced" means Amazon describes it as coming. "Not in the announcement" means Amazon did not mention it, which is not the same as saying it will never exist.

Is it free, and who gets it first?

Amazon says the tools come at no additional cost to sellers. What still costs money is the fulfillment. When you click to fulfill an order through Amazon, it becomes an MCF order: Amazon's Multi-Channel Fulfillment page (checked September 25, 2026) describes fulfillment costs that include picking, packing and shipping, and Amazon's Walmart guide says Amazon charges no referral fee on MCF orders. The other channels keep charging their own fees. Walmart's pricing page (checked September 25, 2026) says its referral fees vary by category and are deducted once you complete a sale, whoever ships the order.

Access is gradual. Amazon has not said which accounts get the tools first, and it gives no date for sellers outside the US store. The quickest way to check is to open the Settings menu in Seller Central and look for the multichannel settings page. If it is not there, the rollout has not reached your account yet, so plan the quarter around the tools you run today. For MCF surcharges and holiday peak fees, see the order routing guide.

Where does your multichannel data live?

In your Amazon seller account. Amazon's announcement says a seller decides which channels to connect and what data to share, can disconnect at any time, and that strict access controls keep a seller's data from other sellers and out of Amazon's retail business decisions. It adds that off-Amazon data stays accessible to the seller for managing their business. Marketplace Pulse points out that Amazon has long tracked what its sellers charge elsewhere and can now also see how much they sell there, while repeating Amazon's statement that the data won't inform its retail business.

Two practical questions stay open. The announcement does not say whether the combined multichannel data can be exported or reached through the SP-API, so plan to keep your own copy of each channel's orders and profit data. And if your team runs Walmart and Shopify work from inside Seller Central, the daily workflow for those channels now depends on access to your Amazon account. Neither point is a reason to avoid the tools. Both are reasons to connect deliberately, one channel at a time, knowing what you share.

Concentration is the larger issue. Marketplace Pulse, citing its 2026 Seller Index (a survey-driven study of 181 marketplace businesses), reports that 71% of Amazon-primary sellers active on at least one other marketplace still earn three-quarters or more of their marketplace revenue from Amazon. Its reading is that the risk for sellers is deeper dependence on a channel many of them are working to rely on less. A Seller Central hub makes Walmart and TikTok Shop easier to run; it does not make you less dependent on Amazon.

When is Amazon's view enough, and when do you need your own system?

For many sellers Amazon's tools will be enough, and trying them costs nothing extra. They are likely enough when these hold:

• You sell on Amazon plus one or more of the four connected channels, and nowhere else.
• Most orders ship from FBA through MCF, or from one warehouse you manage by hand.
• You want one order screen and, once it arrives, a channel-level profit view, not custom rules.
• A small team runs operations and can work at the pace of Amazon's rollout.

You need a system of your own when stock sits in your own warehouse or several 3PLs and orders need routing by cost and ship-by date; when you sell on channels outside the four, or outside the US; when your ERP, accounting or purchasing needs the same order and stock data; when you want per-channel price rules, stock buffers and replenishment across channels; or when you want your order and profit history in systems you control, whatever happens to one account. That layer does not replace Seller Central. Seller Central stays your Amazon cockpit, and the rules and data live on your side.

Ecomsellertool builds that layer. We deploy Growth OS on your own accounts, where it keeps prices, stock and content consistent across Amazon, Walmart, Shopify, eBay, TikTok Shop and 15+ other marketplaces. Then we add the connectors, rules and AI agents you need, within limits your team approves. You keep your accounts, your data and the custom code we build; the Growth OS base is licensed to you.

A custom layer is not always the answer. For a brand on two channels that ships everything from FBA, Amazon's free tools are usually the better fit. If you already pay for several seller tools, see how an owned system compares with a SaaS stack, and what a multichannel operations agent does on your own accounts. We have built on Amazon's seller APIs since 2017, and we would rather you start with the free option than buy a system you do not need.

What should a US brand do this quarter?

Treat the launch as a free upgrade to test, not a reason to change your stack on the way into Q4 peak.
