Hey there, @clinic-uk5.
Any activities done in your account can be found in the Audit log. You'll want to utilize it to get the information of the deleted invoice and recreate it. You can customize it by using the Filter tool to narrow down the data.
Here's how:
- Go to the Gear icon and select Audit Log.
- Pick the user, the date it's changed, and choose Deleted/Voided transactions under the Events filter.

- Click Apply.
- Locate the deleted transaction.
- Use the browser search.
- Press Ctrl + F on your keyboard.
- Enter a keyword about the deleted invoice.
- Under the History column, click View.
- Under the EVENT column, you can find all the information needed for the transaction.
