I paid off the wrong customers bill how do I fix it

Hello @jeff118,

I would be happy to help you fix the applied payment. Thanks for reaching out! 

If the payment was not applied to the correct invoice, you'll need to unlink or delete the payment transaction for the invoice to be tagged as Open. Then, create a receive payment and link to the correct invoice.

Here's how to delete the payment:

1. Select Sales from the lefthand menu.
2. Select All Sales. 
3. Find and select the payment transaction that is incorrect.
4. You'll be routed to the Received Payment page.
5. Select More at the bottom and choose Delete.
6. You'll be prompted with Are you sure you want to delete this? Select Yes.

Once done, you can now create a payment and apply it to the correct invoice. If you would like a reference, this article contains the steps: Record invoice payments in QuickBooks Online.

That should do it! Let us know how it goes and, as always, we are here to answer any questions. Enjoy your day.
