Thank you for your message.

The payments feature supports 3 payment methods:

Stripe: connect your Stripe account to WIIN.io to collect payment for your products.
Paypal: connect your PayPal account to WIIN.io to collect payment for your products.
Proof of payment: set up a procedure to confirm payments made outside the WIIN.io platform (invoice, check, wire transfer, etc.).
