- 05migration from an existing provider and risk around active customers
What we clarify first

- 02Do you need one-time checkout, subscriptions, trials, invoices, paid access, or refunds?
- 03Which systems must receive payment status updates after each event?
- 04Do you already have provider accounts, products/prices, tax settings, and legal checkout copy?
