Thanks for taking the time to post this here in the Community, @Johnvcd. I'll share some information about your invoice concern in QuickBooks Online (QBO).
If an invoice is voided, you'll need to recreate it so you can proceed to record it back. You can utilize the Audit Log feature to get the exact information that was on the invoice. Here's how:
- Go to the Settings
menu.
- Choose Audit Log.
- Click the Filter button.
- Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
- Click Apply.
You can refer on the screenshot that I've added below for visual reference.

After performing the steps above, you’re now ready to manually re-enter the invoice. For further details, please see this resource: How to create an invoice.
