Mechanical Aids

Abstract

The purchase and sale of goods involves, among many operations such as record-keeping and stock-control, the making of calculations. Depending on the nature and size of the business a range of aids will be used. The exact nature of these aids will depend on such factors as the number of transactions involved, the complexity of the business, the cost of the aids and the purpose to which the aids can be put other than for one specific purpose — and the cost of training staff to use them.
