Help! I have marked an invoice paid in QBSE that has not been paid. How do I fix this?

Thanks for dropping by the Community, lesleykimllc-gma.

Let’s duplicate the invoice so you’ll no longer have to recreate it. Then, delete the paid one in your company to keep your records in order.

To duplicate:

1. Go to the Invoices menu on the left panel to view all sales transactions.
2. Choose the invoice you’re working on.
3. Hit the View drop-down under the Action column to select Duplicate.
4. On the Invoice page, press the Save button.

To remove the paid entry:

1. Tap the Invoices menu on the left panel.
2. From the list, locate the paid invoice you wish to remove
3. Click the drop-down menu under the Action column and select Delete.
4. Press Yes to confirm.
