Hi there, @Lisa237. I'm here to help you make the billable time and expense unbilled. 

To make the billable time and expense show as Unbilled, you'll have to delete the invoice that links to them. Once done, you can open reports that will verify that the time and expense are Unbilled. Before doing so, I recommend creating a backup copy of your company file so you'll always have the original information you can restore at any time in case of data loss or damage.

Once done, let's proceed in deleting the invoice. Here's how:

1. Open your QuickBooks Desktop (QBDT) program.
2. Then, go to the Customers menu and select Customer Center.
3. Look for the customer the invoice with billable expense and time is allocated.
4. Double-click to open the invoice.
5. Next, click the Delete icon and then, select OK twice. 

Then, to check the billing status, you'll have to open the Time by Job Detail report and Unbilled Costs by Job report. Let me guide you how:

1. Navigate to the Reports menu 
2. Then, go to the Time, Jobs, & Mileage section and select the Time by Job Detail report.
3. Look for the specific customer and find the time.
4. In the Billing Status column, it must show as Unbilled.
5. Next, go back to the Reports menu and choose Customers & Receivables.
6. From there, locate the customer and you can see that the expense transaction's Billing status is Unbilled. 

Also, you can easily customize your template in QBDT if you want to modify your invoice form to include and exclude information you need and don't need.
