Recently I got an idea to develop a mobile software which aims to enablecompanies run more efficient and organized with field employees as well as profitable businesses. Right now, I just have these features for this mobile app.

1 Mobile signing of the attendance, Daily work report and scheduling/dispatch
2 Customer database
3 Job tracking 
4 Field data capturing and sharing
5 Invoicing and payment processing 


But I am not sure whether this kind of software sounds interesting and useful for business performers, so I wonder are you willing to give me any suggestion about this? 

And if possible, would you please give me some insights by doing a quick survey?
