We have 8 inspectors onsite who need mobile apps, and 5 office staff who need full licenses. How many of which D365 licenses we need?

Good day Divyani Garg,
Currently Dynamics 365 License Pricing is separated for different business area while not for web app or mobile application.
In other words, you still need to buy full application license for above mentioned 8 inspectors to enable Dynamics 365 Mobile Client Application.

Pls no hesitate to follow up if you have any other questions. Have a nice day.
