Issuing a Customer Credit Memo and applying to an invoice

Hi, @KelleyO.

Currently, we don’t have any issues reported about applying a credit memo to an invoice that shows the credits open.

As a workaround, you can delete and recreate the credit memo and reapply it again to an invoice.

Here's how:

1. Click the Customers menu and select Customer Center from the drop-down list.
2. Select the Customers & Jobs tab.
3. Choose the customer with the available credit from the customer list.
4. Open the customer's Invoice.
5. On the Customer Recent Transaction section, click the Credit Memo link.

6. In the Credit Memo window, click the Delete button above.

7. If you receive a warning that voiding the memo changes any attached invoices, select OK.
8. Then recreate the credit memo and apply it to an invoice.
