From within a selected project dashboard visit the Project Settings page
Next go to Fees
You'll be able to adjust your project type and how your fees are calculated, as well as add, remove, or adjust fees
To add a new fee click on ADD FEE. If you've set the fee display method to Separate you'll have to choose a cost code to act as your fee. If you've chosen Blended you'll only need a custom fee name
