Hello
I need to add new payment for some customer but not all customer.
For exemple I can select on backend the type of payment for some customer ex) payment in 30 days or payment in 45days.
I have create new payment but it concern a group of shopper and not a customer that I want.
Assign customer to a group yourself (manually) or try those custom VM extensions in 3rd party forum section.
Ok thank I ve create new group shopper and assign to the customer.
