Before an AI agent can buy from your Shopify store, your checkout needs to work for a program, not just a person. Here are the seven things to fix, from the one that breaks agents most often to the one most stores forget.
1. Guest checkout that doesn't force an account
Forced account creation stops most agents cold. A buyer, human or machine, should be able to complete a purchase without signing up first.
2. A critical path free of blocking popups
Email and discount popups that cover the page break the flow. Agents follow a defined path. A modal in the way ends the transaction.
3. Machine-readable product data at the point of sale
An agent confirms what it's buying from Product and Offer schema. If price and availability aren't readable, it can't verify the purchase.
4. Live, accurate inventory
If stock status lags reality, an agent may try to buy something that's gone. Keep availability current so the purchase doesn't fail at the last step.
5. A payment flow that supports programmatic checkout
Shopify's accelerated and programmatic checkout paths, documented in its developer API, are built for this. A payment step that assumes human taps is a wall.
6. Clear shipping and return terms in structured form
Agents weigh total cost and risk. Shipping cost, delivery window, and return policy in readable form help an agent decide to complete the buy.
7. Consistent product identifiers
GTINs and SKUs that match across your feed and store let an agent confirm it's buying the exact item a shopper asked for. Google's identifier guidance applies here too.
How we chose this list
These seven come from walking live Shopify checkouts the way a program would and marking every point where a human-only assumption stopped the purchase.
