Refund customer with check

Welcome to the Community, @dntoto.

Processing a refund for a customer in QuickBooks Online (QBO) is pretty easy! However, it won't make the invoice open again. You will need to recreate it again after the refund.

Here's how:

1. In QBO, go to the + New button at the top left to get to the Refund receipt. 
2. Enter the customer's name and pick the bank you deposited the payment in the Refund From drop-down.
3. Add all items in the Product or service column and the other necessary information.
4. Hit Save and close.

For further guidance about the process, consider checking out this article: Record a customer refund. Once done, you can now recreate the invoice. Refer to this article for the detailed steps on how: Create invoices in QuickBooks Online.

That is what I thought.  Thank you so much!
