Hi Bradley,
Thanks for taking the time to suggest this idea.

Our Stripe module currently supports Apple Pay, Google Pay and Microsoft pay: https://docs.whmcs.com/Stripe#Payment_Request_Button

We have separate modules for bank transfer payments via ACH and SEPA:
- https://docs.whmcs.com/Stripe_ACH
- https://docs.whmcs.com/Stripe_SEPA

Which payment method would you like to see implemented in addition to these in future?
