In almost all business area purchasing information system has been indispensable. The operation of this system has over decade been practiced manually in most business organization.

Consequently, the thesis was prepared in view of showing how computerized purchasing information system can enhance the processing of records, storage of record and retrieval of files and updating of purchasing files. It also establishes the advantage of computerized purchasing information system over the manual system in shop and save supermarket, Uyo.

Purchasing information system is the activity of acquiring good or services to accomplish the goals of an organization. The major objectives of purchasing are to maintain the quality and value of a company’s products, minimize cash ties-up in inventory, maintain the flow of inputs to maintain the flow of outputs, and strengthen the organization competitive position.

Professional competence therefore, is important in managing the purchasing involves the activity directed towards securing the materials, supplies, requirement and services required in the operation of an enterprise.

These activities have to be performed with optimum efficiently, economy and effectiveness. These three factors are the key factors in obtaining excellence in managerial performance. since materials constitute the largest chuck of the creation of value (for which alone to customer is willing to pay a price), it is necessary for the purchase to exercise at most prudence in ensuring for the purchaser that the ultimate values is obtained for every ripe spent on material VFM (value of money) has to be the slogan of the purchase department.

Today purchasing is not the dame as buying of yester years. Buying is money the act of procuring at item of material at a price. On the other hand purchasing functions is the improvement of profit and actively searching out and in planning new ideas for improvement of the company’s product achieve this objective by cost of material.

·        To examine the present mode of purchasing information.

·        To find out the problem associated with present method of purchasing.
