You can set up price per mile / kilometre similar to taxi meter but using the distance calculated by Google Maps API.
Price per mile / kilometre can be set in two different ways: Generally for all cars or separately for each car.

To set up Price per mile / kilometre for all cars (same price for all cars) please go to the back end > Dashboard > Settings > General price settings > Price per mile / kilometre: XX (this setting will show either Kilometre or Mile based on your set up in Settings, please just use Numbers and "." in the input box).

To set up Price per mile / kilometre for each car individually please go to the back end > Cars > Edit/New Car > Use as taxi: Yes > Price per mile / kilometre override: Yes > Use tariff: No > Price per passenger: No > Price per mile / kilometre: XX  (this setting will show either Kilometre or Mile based on your set up in Settings, please just use Numbers and "." in the input box).

Alternatively when you set Price per mile / kilometre: Yes and Use tariff: Yes you can select one or multiple tariffs to assign to this car.
Tariffs can be set for different times of the Day with different prices. Tariffs have to be assigned to cars so pricing is calculated based on the Tariff. More about Tariffs here (opens in new window).

Notes: 
  • If you have set Use tariff: Yes but you did not select any of the available tariffs then this car may not show in the search results or show with price 0 (depending on set up). 
  • If Use as Taxi: No, then this car will not show for any search result for price calculated for distance travelled.
  • You can check pricing with Price debugging feature (link opens in new window) at the front end when logged in as Admin.
Don't forget to Save the Car screen so changes take effect.
