Our drivers are paid for work orders on Field Service for the miles driven to the location and also for the hours spent driving to the location and the hours spent on the location.

In the price list there is only one unit which is time unit (per hr etc)

How can we add per mile unit in the pricelist?

Next quest question about the quantity calculation for the miles and the time. 

Miles are calculated by the schedule board after the work order is completed by the resource. This should be used to charged in the invoice for the work order.

Time taken is calculated by the schedule board when the resource updates the time to complete from the resco mobile app. This should be used to charge in the invoice for the work order.
