Hello, @etwelding.
I hope you're doing well. You can edit invoice numbers in QuickBooks Simple Start by opening the invoice and editing it. The steps below will show you how:
- Navigate to the Invoicing tab and select Invoices.
2. Find the invoice you need to edit.
3. On the right-hand side of the screen, click the drop-down arrow, and choose View/Edit.
4. Enter the correct invoice number, then press Save and close.
Now you have the correct number on your invoice. You can find more information in this article: Customize invoices, estimates, and sales receipts.
