I'm seeking what online shop system to use. How easy it is to customize e-commerce module with different payment systems like some national e-payment systems? Like the systems to make it possible for the customer pay by e-payment, where customer is directed from the online store to e-bank and when logged in to his/her e-bank, the system gives the payment information and customer can pay the order straight away and will be returned to the online store. I have the codes and information from the bank to put in forms etc. what are needed in the payment system, just asking if it is possible to to add this kind of payment system with other payment methods in SS e-commerce?
I need two paying methods, this e-payment system I wrote, and paying by bank transfer, when after ordering customer gets the paying information and after money transfer the shop owner sends the order. I read some other topic where it said the cheque option can be used because it is like bank transfer (bill payment). I'm not so familiar with these terms, cheque and others. When talking about paying by "bill" means here usually that the customer gets the bill with the order, so pays after receiving the order. And it is common to speak about "pre payment" when after ordering the customer pays by bank transfer and after receiving the payment shop owner sends the order. And that "e-payment" system, when the customer pays when ordering and the shop owner sees the payment straight after order has been made and can send the order.
