Forum Post: Credit amount on customer account in AR to be paid by AP check

Hello. Hope somebody can help us out with this. My employer owes a customer a certain amount due to returns, etc. The customer has found a new supplier and will not order any more items from us. We would like to refund the customer, since there will be no future AR invoices, by issuing a check from AP. How do we apply the AP check to the credit balance in AR and at the same time get the credit memos in the aging cleared out? We are using Microsoft Dynamics SL 7. Thanks and regards, Camilla
