Hi peterandrasmark
We don't have any payment processor available at this time that supports bank transfers but our team has been discussing it this morning and decided to add support for this kind of payments through Sofort.
We are going to prepare our site and we'll add this payment method the next month. If you can't pay through PayPal or a credit card (Stripe), you should wait for this to be ready.
But, please note that this kind of bank transfer payment isn't compatible with recurring subscriptions, so if you use it, it won't be renewed automatically and you'll have to pay manually each time the subscription expires.
Best Regards,
Salva.
