FAQ

Is this only about adding a payment button?

No. The focus is the full order lifecycle: checkout, callback handling, state sync, notifications and admin operations.

Can this connect to an existing system?

Yes. Existing order, membership or admin systems can be integrated through defined business rules.

How do you reduce payment-flow risk?

By defining states, duplicate callbacks, failure handling and end-to-end test scenarios before launch.

Best input to send first

What you sell, how users pay, what happens after payment and whether an existing order system is already in place.
