September was a busy month for agentic commerce, and a revealing one. Anthropic, WooCommerce and Amazon each shipped AI agents for shopping or selling within three weeks of each other, and none of them lets the agent finish the job alone. The shopper-facing agents stop at the cart. The merchant-facing agents stop at a proposal a person has to approve.
We think that is the right design, and that the industry should stop describing it as a temporary limitation on the way to fully autonomous buying.
What shipped this month
On 2 September, Anthropic released Claude Commerce Agents, an Apache 2.0 reference blueprint containing two agents. The shopping agent searches, compares and builds a cart, then hands off to the store's own checkout. The merchant agent analyses sales and drafts listings, prices and campaigns for staff to approve. The repository states that nothing in it places an order, charges a card or changes a live listing.
On 16 September, WooCommerce published its adaptation of that code in its Agentic Tools repository. Its developer blog states the boundary plainly: the assistant never places an order or takes payment, and checkout stays on the store's own page. Changes on the merchant side are staged until a person approves them.
On 23 September, Amazon expanded Seller Assistant, its AI tool for marketplace sellers. The update adds persistent memory, always-on workflows that monitor inventory, pricing and account health, and a plugin that brings the assistant into Amazon Quick and, in beta, Claude. Sellers choose whether each workflow only surfaces recommendations or takes actions, and Amazon says actions are reviewed and approved by the seller before they are carried out. Amazon says sellers accept the assistant's recommendations more than 90% of the time. That figure is Amazon's own and has not been independently measured.
The releases cover different sides of the transaction. They draw the same line.
The evidence for keeping a person at checkout
The clearest evidence comes from the one large experiment that removed the person. OpenAI launched Instant Checkout in ChatGPT in September 2025, letting shoppers pay without leaving the chat, and Walmart listed products through it. In March 2026, Walmart EVP Daniel Danker said that purchases completed inside ChatGPT converted at one-third the rate of shoppers who clicked through to Walmart's site. OpenAI pulled back from native checkout in favour of purchases handled by merchants.
Consumer research points the same way. Speaking at the Goldman Sachs Communacopia + Technology Conference on 8 September, Visa CEO Ryan McInerney said Visa is seeing adoption of AI for shopping but not yet for autonomous payments, and named trust as the barrier. The next day Visa published its Trust Index: in a Harris Poll survey of 2,065 US consumers fielded 26 to 28 May 2026, 23% said they trust generative AI to handle payment transactions on their behalf. Visa commissioned the study and sells agentic payment infrastructure, so it is not a neutral party. The same survey found 61% would trust Visa itself to handle agentic transactions, a result that flatters the sponsor.
Forrester's mid-2026 assessment reaches the same conclusion from the analyst side. Most agentic experiences are still conversational, humans drive decisions and checkout in most cases, and true autonomous purchasing is rare.
Why the split makes sense
Read together, these sources describe a clear division of labour. Agents are being adopted for the work around the purchase: discovery, comparison, cart building, listing drafts, pricing alerts. The payment, and any change to a live store, stays with a person.
That is not a failure of ambition. Checkout is where a retailer holds the customer relationship: the account login, the loyalty balance, the saved card, the returns terms, the fraud screening. When Instant Checkout underperformed, Walmart did not abandon ChatGPT. It put its own Sparky assistant inside it, routing shoppers from discovery in ChatGPT into a Walmart environment with account linking, loyalty and payment. The retailer kept checkout and moved the agent.
The approval step on the merchant side works the same way. A pricing agent that drafts a change for a person to accept is a productivity tool. One that changes live prices unsupervised raises questions about liability and error handling that a draft-and-approve design avoids. If Amazon's acceptance figure holds up, sellers are comfortable delegating the analysis while keeping the final click.
What to watch
The holiday quarter is the first real test of the handoff model at scale. The number that matters is conversion for agent-assisted sessions compared with ordinary ones, and none of this month's launches has published it. WooCommerce's own documentation notes that core WooCommerce records no session or conversion data for its agent. Retailers running cart-building agents through November and December will have that data early next year. If they share it, the industry will learn whether handing off to checkout does more than add a chat window to the storefront.
Until consumer trust in delegated payment moves well beyond the level Visa measured in May, we expect the checkout button to stay where it is: on the retailer's own page, with a person pressing it.
