I have invoices that were deleted by mistake, can I recover them

Hi there, @dadavis. Once you've deleted the Invoice in QuickBooks Online(QBO), there's no option to restore it. However, you can use your Audit log to recover some details, then recreate your invoice.

To access the audit log report, click on the Gear icon and select Audit Log. You can filter by date, user, and transactions (invoices) you wish to view, or use the search menu to find them. Click on View to see the invoice details. You can copy and create a new invoice.

After that, click the + New button and select Invoice. Then, enter all the details and click Save.
