PURPOSE: A purchase/sale management terminal and a purchase/sale data management method are provided to accurate sale unit price used for a sale product and to calculate accurate inventory by giving an identification index to an individual unit purchase product.

A purchase/sale DB module(120) stores the purchase/sale data inputted from the interface module. A control module(130) calculates product costs according to cost of purchased product using the predetermined purchased product identification index when registering a sale of a sold product. The control module calculates a profit using the cost of sold product corresponding to the sold product identification index and the unit cost of sold product corresponding to the purchased product, and calculates inventory using cost of purchased product of the corresponding purchased product with the finished product identification index.
