Change an incorrect "mark as paid" on an invoice that has not been paid

Hello there, vivatherapy.

It's very easy to manage the invoices in QuickBooks Self-Employed.

We can mark it back to unpaid if you incorrectly mark it paid. You can follow these steps:

1. Go to the Invoices tab.
2. Find the invoice you want to change and click the drop-down arrow beside View.
3. Click Mark as unpaid.

I've added some links for more details about invoicing:

I'll be here if you need anything else. Wishing you all the best and take care!
