Strange issue with unbilled time appearing that has already been billed

Thank you for being a valued QuickBooks Online (QBO) user for such an extended period, @bcluxton. Let me assist you by providing some steps to help you understand why previously billed time is reappearing as unbilled.

Once a billable time is invoiced, it will automatically be closed since it has been billed. One possible reason it reappeared could be that someone accidentally modified or deleted the invoice transaction.

To check this, let's run the audit log report in QuickBooks. This report will provide a comprehensive view of all account activity, allowing you to easily monitor sign-ins, modifications, and updates to customer, vendor, employee, and list elements. Please follow the steps below to proceed:

1. Go to the Gear icon and select Audit Log.
2. Use the fields on the Filter panel to trim down the information in the report and focus it more on the changes made to the accounts.
3. Select Deleted/Voided transactions or All transactions in the drop-down list for Events.
4. Click View in the History column to drill down the activity.
   
   

If there are no unusual activities in your QBO account, I recommend reaching out to our technical support team. I understand that you have already contacted them. However, it would be best to reach out again, as they have the necessary tools to conduct a screen-sharing session for a more thorough investigation into this issue.
