One account, every app
A first-time customer can pay by card or bank transfer before setting up a Stack account. Their balance and saved cards are already there.
Stack Docs
Let customers pay first, then set up a reusable Stack identity for faster checkout next time.
Three lines in your app
Your server creates a payment. Your app opens the Stack sheet with presentPaymentSheet.
Your webhook fulfils the order.
Card, bank and transfer
First-time customers pay by card, bank or bank transfer, and that payment creates their Stack account. Nobody is turned away for having no balance.
Your money, on request
Every payment lands in your Stack balance, net of fees. Pay it out to your bank whenever you like.
