Thanks for joining this thread, Choreo.

To verify my understanding, are you trying to include a PAID stamp on printed and emailed invoices, or are you trying to remove it? You can follow the steps in GlinetteC's post to enable your stamp. This will also enable it to be viewed when viewing the invoice on-screen in QuickBooks.

Any invoices which have been paid should be showing up in QuickBooks as paid. If they aren't, please try to include a screenshot showing what you're seeing when viewing paid invoices. This will help me to better understand what you're encountering.

If you'd like to remove stamp on printed/emailed invoices, you can clear stamps from your invoice template. For detailed steps on doing so, you can refer to our Customize form templates article.

I've also included a detailed resource about working with your Past Due stamp which may come in handy moving forward: Show Past Due stamp on invoices

I'll be here to help if there's any additional questions or information you'd like to provide. Have a wonderful Tuesday!
