Let's talk credit memos, CLC6.

When you create a credit memo it will create a negative amount in your Accounts Receivable register. You can choose what happens from here. There are a few options:

• Retain as an available credit. QuickBooks enters a negative amount in your Accounts Receivable (A/R) register for the credit memo. You can use this credit as payment for another transaction. If you chose to retain as available credit, you'll see the available credits in the customer payment window.
• Give a refund. You can issue the refund in cash or a check. If your customer used a credit card, learn how to refund a credit card payment.
• Apply to an invoice. QuickBooks opens the Apply Credit to Invoices window. Select an invoice you want to apply this credit to.

You can read more information on this by checking out this article: Give your customer a credit or refund in QuickBooks Desktop for Windows.
