Which assistants send shoppers to your own checkout

Shopify documents ChatGPT shoppers completing on the merchant’s own checkout in an in-app browser, and Google AI Mode, Gemini and Microsoft Copilot completing in the AI channel’s Shopify-powered direct checkout. The split determines where your risk sits, and it has moved once already, so it is worth rechecking rather than memorising.

There is one documented split worth knowing, and it decides where your risk sits.

The documented positions

Shopify’s help centre says ChatGPT users "complete their purchase on your online store checkout in a ChatGPT in-app browser, or in a new tab when customers use ChatGPT web".

The same documentation says shoppers using Google AI Mode, Gemini or Microsoft Copilot complete their purchase "in the AI channel’s Shopify-powered direct checkout without having to leave their chat conversation".

What each side demands

The overlap is large: both require correct price, variant level availability, identifiers and stated terms. The difference is whether a checkout defect can cost you an order.

Do not memorise this

The assignment has already changed once. Retail Dive reported on 25 March 2026 that OpenAI was retiring the first version of Instant Checkout, moving purchases that had been completing inside ChatGPT back to merchant sites.

Anything written confidently about this in early 2026 was wrong by spring. Treat the split as a thing to recheck on a cadence, not a fact to learn once. See what changed when Instant Checkout was retired.

The practical position

Build for both. That sounds like twice the work and is not: the data work is shared, and the additional cost of the checkout half is one test run cold on a narrow viewport, tied to checkout and theme changes.

Questions

Can I just optimise for one pattern?

Not safely. Both are live simultaneously, and the assignment has already changed once during 2026. A store optimised only for in-channel selling is exposed the moment an assistant starts sending traffic to its checkout.

Which pattern is better for merchants?

Checkout on your own store keeps the customer and the order data, at the cost of owning the failure. In-channel checkout removes your checkout as a risk and leaves your data carrying the sale alone. Neither is strictly better.

How do I keep this current?

Read your platform’s documentation on a cadence rather than relying on any article. This is the single most changeable fact in the whole subject.
