Billable Expenses option is only available in QuickBooks Online Plus and Advanced version, Erica.

You'll want to upgrade to help you record and easily track your company's billable expense from Bill or Expense window every time you enter a transaction.

If you haven't already, you can try logging in using a private browser to check if the billable expense appear. If it works, go back to your main browser and clear its cache. As an alternative, try to use other browsers like Google Chrome, Mozilla Firefox, or Internet Explorer.

Let me know how these steps work. I'll be right here if you need more help.
