There are a number of different kinds of taxi dispatch system, all with different prices – ranging from cheap, smart phone-enabled software apps to expensive high-end installations. Generally speaking, it's possible to either rent software from cab tracking companies, or buy it outright. Renting means avoiding expensive upfront costs while still getting full software and hardware support, with renting on a per-car basis giving you a lot of control over what you pay for. If you opt to buy your software upfront, you can expect to pay anything from £200 to £1,000, for more high tech systems.
