I'll make sure your invoices are recorded and received their payments accordingly in QuickBooks Desktop (QBDT) for Mac, @neverstoplearning.
You'll have to delete the invoice and then recreate it to appropriately apply a credit memo. This way, you're able to pay the invoice and record its payment.
First, find and open the invoice, then select the Delete option. Next, recreate it through the Customers menu and select Invoices.
Then, go ahead and create a credit memo. Here's how:
- Go to the Customers menu and select Create Credit Memos/Refunds.
- To create a credit memo, click Create a Credit Memo on the left panel or click the + at the
bottom of the list. - Enter the information for the credit memo/refund, and click Save.
Once you're done, apply the credit memo to your invoice.
