How can I edit an incorrect entry for invoice paid when it has not yet been paid?

Yes, you can correct the transaction that was matched to the wrong customer invoice in QuickBooks Online (QBO), stevegrigg6.

We can delete the incorrect payment to open the invoice again. Then, we can reapply the payment to the correct invoice once it's paid. Here's how you can delete the misapplied payment:

1. Go to the Sales menu and select Invoices.
2. Locate the invoice that was incorrectly mark as paid.
3. Click on View/Edit open it.
4. Look for the Payment made link which usually shows the amount and date of the payment.
   
5. This will open the Receive payment screen.
6. Click More and then select Delete.
   
   
    

If you want to unapply the payment from the wrong invoice and keep the payment record itself, you can often go into the Receive Payment screen, uncheck the box next to the incorrectly applied invoice, and save it. It will make the payment an unapplied payment or credit on the customer's account, which you can then apply correctly.

If you initially matched a downloaded bank transaction to the wrong invoice, you might need to Undo the match from the Banking section.
