If your vendor issues you a check for a credit or overpayment that you made you will need to do the following two steps in the program. Go into the Edit Payables and clear the transaction and then enter the funds into the Deposits form. Below is a list that describes how to handle both of the above steps.
Open the Edit Payables form and select the vendor you want to receive a credit or overpayment for. Select a Cash Account in the Bank Account field instead of your usual checking account. You will need to enter a dummy check number in the check no field. Leave the A/P field defaulting to the Accounts Payable ID. Select the line item that displays the credit or overpayment and enter the credited amount in the amount paid field and the payment field. Then Post the Payable.
Next go into the Deposits form and select the bank or checking account you want to deposit the funds into. Enter the amount of the refund and in the Line Item Detail of the Deposits you will select the Cash Account you selected in the Edit Payables form.
By following these steps, you are removing the Edit Payables entry and receiving the credit or overpayment into your bank account.
