By Impran M N

When a customer is owed a credit, applying it correctly to an open invoice keeps your accounts receivable accurate. This guide walks through how to link a credit note to an invoice in QuickBooks so the balance reflects the adjustment properly.

01Create or locate the credit note

Find the existing credit note or create a new one for the customer whose invoice needs adjusting.

02Open the customer's invoice

Go to the invoice you want to apply the credit against, making sure it belongs to the same customer as the credit note.

03Apply the credit

Use the receive payment or apply credit option to link the credit note amount to the invoice balance.

04Verify the updated balance

Check that the invoice now reflects the reduced amount owed after the credit has been applied.

FAQ

Frequently asked questions

Can a credit note be applied to multiple invoices?

Yes, if the credit amount is larger than one invoice, you can split it across multiple open invoices for the same customer.

What happens if I don't apply the credit note?

An unapplied credit note will sit as an open credit on the customer's account and won't reduce any invoice balance until applied.

Can I undo an applied credit note?

Yes, you can unlink or edit the applied credit if you made a mistake, though it's best to double-check before saving.

Does applying a credit note affect sales tax?

It can, depending on how the original invoice and credit note were set up, so review the tax lines after applying it.
