Frequently asked questions
How much does it cost to start?
The Developer plan is free and includes a full sandbox. Live payments need a paid plan; processing fees are charged separately by your payment provider.
How fast can we go live?
You can build and test immediately. Going live depends on your payment provider verifying your business, which is their decision and timeline.
