Rob Otics Ltd, a small business that specialises in manufacturing electronic-control equipment, has just received an inquiry from a potential customer for eight identical robotic units. These would be made using Rob Otics’s own labour force and factory capacity. The product specification prepared by the estimating department shows the following:
Material and labour requirements for each robotic unit:
Component X ...................2 per unit
Component Y ...................1 per unit
Component Z ...................4 per unit
Assembly labour 25 hours per unit (but see below) Inspection labour 6 hours per unit
As part of the costing exercise, the business has collected the following information:
● Component X. This item is normally held by the business as it is in constant demand. There are 10 units currently held which were bought for £150 a unit. The sole supplier of Component X has announced a price rise of 20 per cent, effective immediately, for any further supplies. Rob Otics has not yet paid for the items currently held.
● Component Y. 25 units are currently held. This component is not normally used by Rob Otics but the units currently held are because of a cancelled order following the bankruptcy of a customer. The units originally cost the business £4,000 in total, although Rob Otics has recouped £1,500 from the liquidator of the bankrupt business. As Rob Otics can see no use for these units (apart from the possible use of some of them in the order now being considered), the finance director proposes to scrap all 25 units (zero proceeds).
● Component Z. This is in regular use by Rob Otics. There is none in inventories but an order is about to be sent to a supplier for 75 units, irrespective of this new proposal. The supplier charges £25 a unit on small orders but will reduce the price to £20 a unit for all units on any order over 100 units.
● Other items. These are expected to cost £250 in total.
Assembly labour is currently in short supply in the area and is paid at £10 an hour. If the order is accepted, all necessary labour will have to be transferred from existing work. As a result, other orders will be lost. It is estimated that for each hour transferred to this contract £38 will be lost (calculated as lost sales revenue £60, less materials £12 and labour £10). The production director suggests that, owing to a learning process, the time taken to make each unit will reduce, from 25 hours to make the first one, by one hour a unit made. (That is 25 hours to make the first one, 24 hours to make the second, 23 hours to make the third one and so on.) Inspection labour can be provided by paying existing employees overtime which is at a premium of 50 per cent over the standard rate of £12 an hour. When the business is working out its contract prices, it normally adds an amount equal to £20 for each assembly labour hour to cover its general costs (such as rent and electricity). To the resulting total, 40 per cent is normally added as a profit mark-up.

Required:
(a) Prepare an estimate of the minimum price that you would recommend Rob Otics Ltd to charge for the proposed contract such that it would be neither better nor worse off as a result. Provide explanations for any items included.
(b) Identify any other factors that you would consider before fixing the final price.
