When I tried to use them, they required me to mail in a bunch of paperwork. Stripe doesn't.
But the Problem is not Paymill, it are the acceptance company and many restrictions. I am not sure if stripe has an another way todo it in germany.
But on the other side this means, that stripe is less secure?
The sign-up process is part of the product, and we treat it that way. Onerous paperwork is not an inevitability.
