The Additional Costs Module is used to manage any expense or cost on a trip, aircraft, or crewmember in order to quote, or bill a client or passenger. They can be set up to pull Cost Items automatically in quotes, pull actual costs from flight logs expenses, or remind you to add a cost you don’t always use. The cost items can also be entered manually on a one by one basis for quotes. 

You Can also Access the Additional Costs module from within a quote. 

You can have the Cost Group be tied to an Aircraft Rate Type (the rate chosen from within the quote), Customer, or set it up to be the Default for all new quotes. In the below screenshot, you will see an example of the Additional Cost Module. The ARINCDirect Flight Services Costs could be used to create a Default Cost Group for all quotes.
