minicabit’s system is designed to maximise your chances of getting work going between your office base and anywhere (according to your account settings). Your settings include your Farthest Location which governs how far you are willing to travel for bookings and your Nearest Location which will be the immediate radius around your office.
The ‘free pickup and dropoff postcodes’ that you enter relate to jobs charged on a per mile basis, where the distance from your office to these postcodes are excluded from any distance calculated used to price a job on a mileage basis. This does not mean you will only receive jobs going to or from these postcodes. You will be compensated for this, as the fare will take into account the mileage from your base to the pick up and then to the drop off and vice versa.
