With Kickserv being the most proven field service software on the market of course we have a method to track just about any data common to field service businesses and mileage is one of them.
We have two direct methods to track mileage
Time Tracking notes
Custom work fields
Time Tracking method
Create a job and assign it to your technician
Scroll down to Time Tracker
Create a new time entry
Choose the tech and date
In the notes is where your tech will document the mileage of their vehicle.
And then the number of hours on the job
Finally to report on the miles run the Time Card report from the reports page
Custom Fields method
If your plan supports custom fields you will click on settings > custom fields
Choose [Work fields]
Create a text field using a pick list and add your employees to the list box
Next, create a number field and ensure that its position in the list will make it immediately after its named text field above.
You can make more then one set of these text and number fields if you need to.
You will add your mileage to the job by editing your job and updating your custom mileage fields
To report on the mileage you can create a custom mileage report (see creating custom reports)
We can assist with creating your custom report if you need our help just ask.
