I mistakenly issued a credit memo in February 2018. I used this credit memo to make a full payment on an invoice. How do I correct this error?

Hi there, @jdowns321.

Thanks for posting in the Community. I'd be happy to help and provide some insights about a credit memo that was mistakenly issued in QuickBooks Online.

If you haven't closed your books for 2018, then you still have the option to delete and recreate the credit memo. Deleting the credit memo removes the credit available to the customer. Voiding the credit memo reduces the available credit while still leaving a record in your transaction history for reference purposes.

To do that:

1. Open the credit memo you want to delete.
2. Click the Edit menu.
3. Select the Void Credit Memo or Delete Credit Memo option from the drop-down list, depending on your preference.

Once done you can start recreating the correct credit memo.

If your books are closed already, I'd suggest reaching out to your accountant for further assistance. This is to ensure that your books will be recorded accurately.

Please know that I'm just a reply away if you have any other questions about this concern. Have a great weekend!

1. Un-apply the credit memo to the invoice (Receive Payment transaction where it was applied)

2. Void the Credit Memo (Select "More" and Void, always better to Void than Delete)

3. You may have to fix how additional invoice payments were applied for this customer

4. You may have to re-reconcile the bank account due to changes to invoice payments

5. You will have to redo your financials for the impacted periods
