Where checkout changed
Stripe Tax can calculate and collect tax across markets, but buyers still need to know when tax appears, who handles it, how invoices work, and what happens after refunds.
AI SaaS pricing pages should explain tax-exclusive versus tax-inclusive pricing, VAT/GST or sales tax, invoices, and refund tax handling in public FAQ copy.
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
- Add tax, invoice, refund, and covered-market questions to the AI SaaS payment page
- Keep the test narrow: one service scenario with clear inputs, deliverables, acceptance rules, and human review
What still needs proof
If tax appears only at the last checkout step, high-intent buyers pause or ask support instead of paying. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
