SUMMARY In order to provide the effectiveness of manufacturing industry on the development of our country, to avoid the cuaste of sources, to be keen on the choices made among the investments and to preserve the power of competition both at home and abroad, there must be cost data which are concrete, objective and provided when needed. In this sense, it is the cost accounting system that provides the cost data of firms. Every businessman would like to know how much his goods cost, whether it is possible to reduce these costs, and the validity of the cost techniques he used. In order to provide revenue, firms are to make expenditures (cost). The profit of the firms results from the comperison of the yield with its cost The determination of the price of goods and services produced in the firm is made directly in relation with the cost of related goods and services.

For this reason factor costs should be estimated individually and put in to accounting procedures. It is essential for the firms to buy the raw material and equipment needed during production in the desired amount, quality and time and with the possible least cost. Firms take measures that increase the efficiency of the firm by means of choosing wage systems improved in order to get the employees work effectively.
