I incorrectly marked an invoice as paid. Can this be undone

In QuickBooks Self-Employed (QBSE), once an invoice is marked as paid, it can't be changed back to unpaid. As a workaround, we can duplicate the invoice and then delete the paid one.

Here's how:

1. Find the Action column and click the drop-down arrow.
2. Choose Duplicate from the list.
3. Next, click the drop-down arrow in the Action column for the paid invoice, and select Delete.

Please respond to this post if you have any additional concerns.
