Good day, tony93.
For the time being, we're unable to restore a deleted transaction. However, you can retrieve the information in the Audit Log report.
Here's how:
- Go to the Gear > Audit Log.
- Click the Filter drop-down and select the User, Date, and put a check mark on the Transactions box under Events.
- Choose Deleted/Voided Transactions from the Show drop-down.
- Hit Apply.
- Search for the deleted invoice and click the View link to see the history.
Please see this sample screenshot for a visual guide:
Once you have the details, you can proceed in creating the invoice. Feel free to check out this article that includes a video tutorial: QuickBooks Online - Invoicing and quoting tutorials.
I'm here if you have more questions about invoices or other concerns with QuickBooks Online. Take care and stay safe.
