How do I remove PAID from an invoice that has not been paid?

Hi there, langfordwelding.

I'm here to show you on how to delete payment to reopen your invoice.

Here's how:

1. Go to Sales in the left navigation menu.
2. Go to Invoices tab, then open the invoice.
3. Click the 1 payment made link at the upper right hand above the PAID payment status.
4. Click on the link for the date.
5. On the Receive Payment window, click on More button at the bottom.
6. Click on Delete, then choose Yes.

That's it! You're now able to change your invoice back to unpaid status.

To know more how to receive payments, take a look at this resource: Record invoice payments in QuickBooks Online.
