Maidogo Limited sells NIXAQ, a product manufactured by it, from several retail outlets. In previous years, the company has undertaken responsibility for fitting the product in customers’ premises. Customers pay for the product at the time they are ordered. The average length of time it takes from ordering to its fitting is 14 days. In previous years, Maidogo Limited had not recognised a sale in its books until the product had been successfully fitted because the rectification costs of any fitting error would be expensive.
With effect from 1 April, 2013, Maidogo Limited changed its method of trading by sub-contracting the fitting to approved contractors. Under this policy, the sub-contractors are paid by Maidogo Limited, and they (the sub-contractors) are liable for any errors made in the fitting. Consequently, Maidogo Limited is proposing to recognise sales when customers order and pay for the goods rather than when they have been fitted. Details of the relevant sales figures are:
