Since the Markup % are haven't set up, you'll need to delete and recreate the billable invoices. This way, you get the new total of your invoices. 

Before doing so, make sure to take note of the details before you delete the transaction. Let me show you how.

If you haven't created a billable expense, here's how:

1. Click the +New icon. 
2. Choose Expense.
3. Add the Payee's name.
4. Select a category and enter the amount.
5. Check the Billable box and add the customer's name.
6. Enter the needed details.
7. Click Save and close.
