To apply a prepayment to a customer’s account, you must use the Cash Receipts Data Entry screen on the Cash Receipts Menu. This would be used if an advance payment is received on an order that has not been invoiced. Following are the step by step instructions:

Enter deposit date -> Select type of deposit code (cash, check, credit card)
Enter the amount of the prepayment for deposit amount
Type the customer code or ? to insert a customer from the display window
Use PREPAY for check number
ABA number can be left blank -> Enter the amount of the payment

Type the invoice number, if known, or use a number of your choice
‘Is This a PrePayment? (CR-N)’ message will display -> Press the Enter key
Bypass the discount field -> Enter the amount of the payment
