It's nice to see you here, @bill12.

I’m here to share a few details about voiding and un-voiding an invoice transaction in QuickBooks Online (QBO).

Currently, there isn’t an option to un-void a transaction in QBO. Once an invoice is voided, it can only be recorded back by recreating it.

You can use the Audit Log Report to figure out the exact information that was on the invoice. Here’s how:

1.    Go to Reports.
2.    Enter Audit Log in the search box.
3.    In the report, locate the voided invoice.
4.    Click the View hyperlink.
5.    Hit Show all.

I’ve attached screenshots below for your reference.

After performing the steps above, you’re now ready to manually re-create the invoice. You can check out this article for further information: How to create an invoice.

That’s it. Please let me know if you have questions or clarifications. I’ll be here to help. Take care and enjoy the rest of your day!
