In one office block there are twelve businesses which use Scrubber to provide cleaning services. At 1 April 20X5 four businesses had paid one month in advance and two customers were in one month in arrears. With effect from 31 August 20X5, one customer terminated their agreement with Scrubber, whilst two additional contracts were signed to take effect from 1 December 20X5. At 31 March 20X6, the same four businesses had paid one month in advance and two customers were in arrears by one month. Each annual service contract is regarded as a contract which gives rise to obligations which are satisfied over a period of time.
