I know it's quite annoying to manually uncheck the billable option in every transaction, @LisaMichelle689.

On the Company Preferences, you can uncheck all time entries and expenses as billable for future transactions. However, when entering items on a bill, it will still automatically check your billable column once you select a Customer:Job on the drop-down arrow. In addition, for existing billable expenses, you need to uncheck them individually.

Here's how to unmark the billable on the Preferences:

1. Proceed to the Edit menu and choose Preferences.
2. Select Time & Expenses on the left-side panel.
3. Click the Company Preferences folder.
4. Make sure to uncheck the Mark all time entries as billable and Mark all expenses as billable box.
5. Once done, choose OK.
   
   

This will disable the automatic billable check mark once you entered expenses on your bill.
