Applying Credit to an Invoice

1 min

You will need the QuickBooks Credit Note and Invoice IDs to link the two together.

Need to create the Credit Memo? See here.

Need to create the Invoice? See here.

To achieve this, you need to create a zero-dollar payment, which is the link between the Credit Memo and the Invoice. The Credit Memo is linked to the zero-dollar payment, which is then linked to the Invoice.
