Field Service Features

I run Operations for a small installation/service company in the US. I am interested in features such as scheduling, field employee dispatch, GPS location tracking, and client signature/payment in the field via an app. Are these features that ERPNext is looking to add in the future? Are there any other companies like mine out there using ERPNext and a separate software solution to add these features? If so, what are you using?

Thank you in advance!

ERPNext does not support these features out of the box. If you want to get them built, you can get them built and contribute them.

I think FafadiaTech has experience supplying FSM functinalities
