Where checkout changed
Payment, tax, and market eligibility remain high-intent questions; readers should not need to re-check applicability from scratch.
List supported regions, payment methods, tax timing, invoices, and refund paths as a reusable decision sheet.
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
- Keep `ai-saas-payment` as the qualification page and link it from this issue
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
Unclear payment eligibility keeps high-intent readers in comparison mode. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
