Hello there, @tvgirl7. I appreciate the effort you’ve put into addressing this issue, and I completely understand how challenging it can be.
In QuickBooks Self-Employed (QBSE), once you mark an invoice as paid, it gets recorded as paid on that specific date. Currently, the option to backdate the payment to reflect a past date is unavailable.
As a workaround, you can add a note to the invoice indicating that the payment has been made. Here’s how:
- Navigate to the left navigation panel and select Invoices.
- Locate the specific invoice and click Edit.
- In the Note to Customer field, add a note stating the invoice has been paid.
- Select the drop-down arrow next to Email, then click Save.

I’ll add this article to help you manage your invoices and set up your preferences: Create invoices in QBSE.
