Harambee (Pty) Ltd (Harambee) was formed by two shareholders in 2004 and manufactures construction equipment in Windhoek. Due to the decline in the construction industry, Harambee,s sales have been declining and they have had to offer more favourable terms to its clients in order to attract sales. The following are some transactions that have occurred with some of the customers:

Sales to UNAM Ltd
UNAM Ltd was building a new lecture hall and so bought 8 cranes from Harambee at a cash selling price per machine of $ I 0 500. The normal selling price is $ I I 200 (based on cost plus a 40o/o mark-up), but because LrNAM is a regular customer, it received a trade discount of $700 per machine.

The sale agreement was signed on 0l June 2016, and, the machines were delivered to UNAM on the same date. UNAM will pay for the machines in instalments as follows: Date Amount  N$

01 June 2016    15 000
31Mav 2017    32 000
3l Mav 2018     44 158

Finance charges at 7% per annum were incurred on the amounts outstanding. Harambee's financial year ends on 3l December of each year, and the entity uses a perpetual inventory system.

Sales to POLY Ltd
Poly Ltd bought small construction tools from Harambee on I July 2018 for $500000. Poly Ltd immediately paid the amount and the goods were delivered on the same day. Poly Ltd was allowed to return the goods within 30 days if they did not like them in which case they would receive a full refund.
Harambee Ltd has vast experience with the sale of these goods and expects thatg0o/o of the goods will not be returned. The cost of recovering the goods is insignificant and the recovered goods can be resold at a profit.
