Google has switched on AI Mode checkout by default for eligible Shopify stores, according to enrollment emails merchants reported receiving this week. Shopify’s own help documentation says Google Analytics and custom pixels won’t fire in that checkout. It fires only server-to-server pixels, for two events: started and completed.
A Form Google’s Own Page Still Asks For
Google’s Merchant Center help page for the feature, built on the Universal Commerce Protocol (UCP), an open standard, still describes an early-access program. Merchants who want in are told to “express interest” by filling out a form, and Google says only product listings carrying the native_commerce(checkout_eligibility) attribute show a “Buy” button for the checkout. Fetched this week, that same page states the checkout “is available for select merchants at this time.” Shopify’s own help page describes something already switched on: “Purchasing in direct checkouts is activated by default for eligible stores, but you can deactivate direct checkout and have customers complete their purchase on your online store instead.”
The two pages disagree on geography, too. Google lists the United States, Canada and Australia as eligible countries. Shopify limits both the merchant’s store and its customers to the US. Neither page resolves the gap between a form-gated early-access program and a default that is already live.
What Is Native Checkout in Google AI Mode?
Native checkout, built on the Universal Commerce Protocol, an open standard, lets a shopper pay for a product inside AI Mode in Google Search or in Gemini, without opening the merchant’s own site. Shopify says it lets “customers complete their purchases in a Shopify-powered direct checkout without having to leave their chat conversation.” Shopify’s page says customers pay by “clicking a Pay now button and paying with a credit card or debit card,” while Google’s page describes paying with Google Pay, using payment methods and shipping information already saved in Google Wallet. Google says the merchant remains the seller of record.
How the Switch Gets Flipped
According to Search Engine Roundtable, Google is emailing merchants whose Shopify stores match their Merchant Center feed to say enrollment already happened. One email, posted to X by Menachem Ani, read in part: “Your Shopify store was matched to your Merchant Center, enabling native checkout on Google AI Mode and Gemini. Customers can now buy your products in AI Mode on Google Search, Gemini, and more.” Another line from the same email: “Eligible products are automatically included. There’s nothing for you to set up.” Search Engine Roundtable, reporting on September 22, says the checkout launched for limited merchants in February and that Google pushed it to more retailers the previous Friday, September 18.
We looked at Shopify’s side of the protocol in May, in Shopify’s Universal Commerce Protocol bet, and product data has been driving AI shopping answers elsewhere too, as when ChatGPT shopping answers shifted to product feeds earlier this month. Merchants who want out go to Shopify admin, Sales channels, then Agentic, deactivate “Allow Shopify to manage for me,” open Google AI Mode and Gemini, and toggle direct checkout off.
Where Analytics Stops Seeing the Sale
Shopify’s help page states the gap plainly: “Google Analytics and custom pixels won’t fire in Google AI Mode and Gemini’s direct checkout. The checkout fires only server-to-server pixels (started, completed), so none of the standard or custom client side pixels fire.” The same page lists checkout blocks that might not load in that flow: ones that collect customer consent for data use and communication preferences, loyalty or rewards experiences, upsells and add-ons, chat or messaging, and informational-only blocks such as trust badges or terms and disclaimer text.
None of that needs a bug to explain it. It needs a sale that never opens the merchant’s own checkout page.
Reconciling the Gap
Google’s enrollment email tells merchants they “manage and retain full ownership” of their customer relationships, data, and sales. What that looks like inside a GA4 report is a separate question neither company’s help page answers, and no source has said how these orders get labeled once they land in a store’s own admin. The practical move for a Shopify merchant right now is to open Sales channels, Agentic, confirm whether direct checkout is on or off, and make that call on purpose instead of by default. Reconciling revenue after that means checking order data in Shopify rather than GA4 alone, because the client-side Google Analytics tag does not fire in that checkout.
