Greetings, @marcia5.

@qbteachmt is correct! Allow me to share additional information on how to mark an expense as billable.

Let's make sure that your QuickBooks preferences is set to mark expenses as billable. Here's how:

1. Go to Edit.
2. Choose Preferences.
3. Select Time and Expenses.
4. Under Company Preferences, put a check mark on Mark all expenses as billable.
5. Click Ok. 

That should do it! This should allow you to create bills and mark your expenses as billable.

Let me know how it works on your end. I'm always here to help you manage your Account Payables in QuickBooks Desktop.
