Horizon accounting system

The Horizon accounting system is an accounting software and electronic point of sale (EPOS) system developed by Fujitsu for the Post Office in the UK. The problems with the Horizon system have been a central part in of a group litigation in what is known as the British Post Office scandal.

The Post Office introduced Horizon around 1999/2000 as a new computerised system for the accounting function both in the Post Office branches, and between the branches and itself. This was (and still is) called Horizon.
