Great to see you in this thread, milesconstruction. Thanks for sharing the troubleshooting steps you’ve taken. I'm here to help make sure your billable expenses are sorted out correctly.

Yes, you're correct. When you go to the reports page and click on the Billed label you will be redirected to the payroll check/expense transactions associated with the deleted invoice.

On the transactions page, you can find the billable expenses and mark them as billable again before applying them to the invoice. Make sure the invoice includes the correct markup to prevent any issues down the line.

I've added screenshots for your reference.
