I have a big number of wrong invoices from 2021 and I need to delete them at once, to re-upload the correct ones. is there a way to do so?

Hi manager26,

Deleting multiple invoices at once is not available in QBO. I understand how much such an option can help you. I suggest finding a third-party app that's capable of doing that process in QBO.

1. Go to the Apps menu on the left navigation bar.
2. User a keyword related to deleting invoices to find an app.

I'm including this article for your additional reference: Void or delete transactions in QuickBooks Online.

Let me know if you have other concerns with your invoices. Have a good one.
