I have received a refund from a supplier (bank deposit). How do i apply that refund to the credit note?

Good day, idoj31,

Since the refund is received through a bank deposit, follow these steps below to make sure your vendor expenses accurate:

1. Click + New on the left pane.
2. Select Pay Bills.
3. Select the bank deposit. You’ll see the amount of the vendor credit in the Credit Applied field. The Total payment should be $0.00.
4. Select Save and close.

Stay in touch with me if you need further assistance.
