Let me share with you why this happen to your invoices, thesign.
In the new invoice layout, there is no option to turn off the custom transaction number. This is because QuickBooks Online aims to prevent duplicate transactions that may cause issues in the future.
As a workaround, if you still have the option to switch back to the old layout, you can turn off the custom transaction number to create an invoice using a similar invoice number.
To resolve the error, you can run the Invoice List report to avoid using the same number that has already been assigned to another invoice transaction. Here's how:
- At the left navigation panel, select Reports.
- Enter Invoice List on the search bar.
- Click the report to open and then select Run report.
