When using the App a field agent can log when they are on route to a job, by selecting the On Route option in the Job, and then they can also log when they arrive so there is a record of the time it took to travel to the destination.
When they have arrived at a property, then they can start the job and then also log when it has been completed.
This will show in the history of that job through the Web Portal by going to Jobs > View Jobs > select the Edit arrow for the job that you would like to view (if the Job has been completed, then make sure to filter the list for Completed jobs) > Job History.
The history will highlight the times when the Job was Started and Completed.
It can also be logged when offline if they are in a no service zone.
