Thanks for getting back here in the thread, @bdrickards.
You can change your invoice by clicking the Edit work info and it's located in the invoice toolbar at the bottom part.
Let me walk you through the steps on how:
- Go to the Invoices tab.
- Click the Mark as paid drop-down in the invoice section you want to edit.

3. Select the Edit option.

4. At the bottom part of your invoice, choose the Edit work info.

5. Edit your invoice.
6. Once done, save the modified invoice.
If you weren't able to see the Edit work info button, you can contact our QuickBooks Support. This way, they can check your account and investigate why the edit button is not showing on your invoice page.
If you have additional questions, please don't hesitate to leave a message in the comment section.
