Today, business entities need to adapt to market conditions, which have practically exhausted opportunities for the development of the trade sphere. Because of the high level of competition, organisations have to develop individual schemes, come up with promotional and bonus programmes to attract the attention of customers to the goods they sell. In the harsh market reality the only true solution will be the introduction of innovative IT-technologies, thanks to which it will be possible to increase the competitiveness of the trading company. With their help it will be possible to integrate information systems of the buyer and the seller, to qualitatively serve the systems of automated ordering of products, to provide prompt information about the operations that have taken place.
