thank you for your reply. A PSP means: Payment Service Provider. 🙂 This is the firm that provides the gateways indeed for all different kinds of online payments. The one I mentioned ‘Mollie’ is a smaller firm that mainly operates in Holland. It is important that PSP firms know the names and services of the firms that provide shopping carts, so the service can be provided.
I once had to apply for a shopping cart of Ecwid. but the PSP didn’t know Ecwid. So they had to turn the house upside down before the gateway was provided. PSP’s are allways very demanding because of legal issues and stuff.
I would like to work with Mollie because they’ve already accepted me.:-)
