Steps to use if Customer has Overpaid an Invoice

1. Apply the full payment to the Customer Order.

 2.  Customer's Invoice will have a credit balance.

3.  Post another payment to the order.  Place this payment in the discount field for the amount of the overpayment.  Make note of the Discount Account code.  You will need this when posting the Accounts Payable.

 4.  Create an Accounts Payable record for the customer.  Use the same code used to discount off the credit balance.  Create a remittance note for the payable.
