摘要

A transaction processing apparatus comprises a memory having a sales information storing region defined for each of a plurality of commodity departments, a cost multiplier rate information storing region for storing in advance the cost multiplier rate, and a deduction amount information storing region. When the price of a commodity sold is entered from a keyboard, the price data is stored in the sales information storing region corresponding to the commodity department thereof. When a deduction amount is entered from the keyboard, the deduction amount is subtracted from the stored price data and the deduction amount data is stored in the deduction amount information storing region. Upon receipt of a command for preparing a report, the cost and the profit are evaluated based on the price data and the cost multiplier rate. A profit report is prepared based on the evaluated cost and profit and the stored sales information and deduction amount information.
