[Gondal]

Hi  my company has contract with one taxi company where i get rides 

i dont understand how to book this invoice 

i attach in image 

1. They charge service fee monthly for their partnership 

4. its airport fee for every ride they charge us 

2.  Its total work like orders money what we get -11815,96

3. Its a service fee for the rides 1878.75 

 and below there are moms

plus minus please help me how to book this 

i chat with them i was confuesd about taxi moms 

they reply me this for taxi earning only

17740+moms(1064) = 18804

15984 total after fee in your app

fee is 2820

18804-2820 = 15984

Note: i will get back 8804 from them in my accöunt
