Need help regarding service business

Hello Community
I have been using frontaccounting since 2014 it is working well for small businesses and managing my accounts for small trading company but for now i recently started service business where i just provide different services and have added all items as a service.
example :
service 1 :  1000
service 2 :  2000
service 3 :  3000
service 4 :  2000
service 5 :  3000
service charges : 2000
total       :   13000

it is working fine but my question is all mentioned items are expenses except my gross profit is service charges item 2000.
but having issue in PL and Sales account all these items are showing me my profit instead of just 2000
I don't now how to set all these items as an expense where it directly post in expenses.

Thanks in advance.
