I know why this happened, dcox1.
You'll see a zero amount on your credit memo because the invoice payment and the credit have the same amount. You can create a credit memo to credit a customer's balance. Here are a couple of ways you can use a credit memo for:
- Customer's payment is higher compared to was is owed on the invoice
- Customer returned a product
- Requests a credit for a service
- Rewarding a customer with store credits
You can refer to this article to learn more about credit memos.
Please let me know if there's anything else I can help you with.
