Good day, checkpnt.
We can apply the payment to the correct invoice.
The first one I can suggest to edit the payment transaction you recorded. Go to the customer's profile, then find and open the payment transaction. From there, unlink it to the incorrect invoice by removing the checkmark. Then, link it to the correct one by checking it. Once done, let's click on Save and close.
Another way is to create a journal entry. You can follow the steps in this article for your reference: How to fix a payment applied to the wrong invoice.
