We are looking for a way to create a gateway that would allow the end customer to pay his bills,   We have the IFS credit card interface installed and operational.   But it appears that module is kind of limited in functionality,   It authorizes at the time an order is released,  collects payment at time of delivery.    We need a mechanism to accept end user payments for their Accounts Receivables via ACH, Wire, Credit Card methods and any other industry proven techniques.  Perfect world it would accept the payment and make an appropriate entry in IFS for the receivables or merely put a payment on account. Has anyone done this?   If so how are you doing it and with what software?
