Enable real time tracking of your deliveries to site. Adding addition functionality to your existing DataScope Delivery System, Haulier app allows drivers to sign onto deliveries and then for you to track them on a map view. The app allows easily adding GPS co-ordinates to your site and gates, which allows an ETA to be calculated and viewed on site and in the app before starting. This application uses background location services in order to track the movement of deliveries to site.
