Where checkout changed
Search suggestions around agentic commerce already include protocol, Visa, Mastercard, Shopify, and examples, showing that the market is asking how responsibility works.
AI product discovery is only the front half. Payment authorization, taxes, refunds, fulfillment, and dispute records decide whether commerce can operate.
Do not trust one conversion number
The useful question is no longer whether a purchase happened; it is which step created the hesitation, missing fact, or measurement gap.
Check the event model
- Build an agentic-commerce responsibility table covering recommendation, cart, authorization, payment, refund, and support
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
The more automated the payment path becomes, the clearer the responsibility boundary must be. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
