Can't I void a invoice which had been duplicated after BAS Submission

We're unable to directly void a duplicate invoice after BAS submission, as doing so could cause inconsistencies between QuickBooks Online records and the BAS you previously filed with the Australian Taxation Office (ATO), Auscar200.

We recommend contacting our Live Support team for assistance with the appropriate actions. They can review your BAS submission and the duplicate invoice to ensure compliance with reporting regulations.

Here's how:

1. Sign in to your QuickBooks Online account.
2. Go to Help and choose the Search tab.
3. In the search field, enter the contact support.
4. Click the Contact Us button.
5. Choose the Have us call you in the Callback section.
6. Follow the on-screen steps.
