Is there a way to retrieve invoices that were in anaccount that was accidentally unactvated ... I did reactivate but my invoices are "gone" ... help

Hi there, @tammystouchups-o. Let me share some information about restoring deleted invoices in QuickBooks Online (QBO).

Currently,  there's no option to restore a deleted transaction in QBO automatically.

Once you delete a transaction, it will be erased from your books. It will no longer appear on your reports or in your accounts. 

You can use your Audit Log to recover some details, and then recreate the invoice.

To  pull up the audit log report:

1. Go to the Gear icon and then choose Audit log.
2. Click on Filter and select Show only these events, Transactions, and Deleted/Voided transactions.
3. Look for the deleted invoice and click View under the History column to get all the necessary details.

After that, click the + New button and select Invoice. Then, enter all the details and click Save. Please check out this link for more information: Use the audit log to re-enter deleted transactions.
