If you paid a supplier too much, record the whole payment in MYOB
If you paid a supplier twice, create a supplier return for the second payment
When an overpayment is recorded, a supplier debit is created for the overpaid amount
Debits can be refunded or applied to other open purchases
To process an overpayment
From the Purchases menu, choose Create bill payment.
Select the supplier in the Supplier field and choose the Bank account.
Enter the total amount of the payment (including the overpayment) in the Amount paid field. If there are multiple bills for the supplier, select the one against which you want to record the overpayment.
Ensure all other details of the payment are entered. See Supplier payments for more information.
Click Save when you're finished.
If the overpayment came through in a bank feed, match the overpayment amount in the bank feed to the payment you created above.
Process the supplier return (Purchases menu > Supplier returns) and choose whether you want to apply the overpaid amount to a bill or receive a refund. You can also hold onto the debit to apply to a future bill.
