One of important instruments for formation of partner relationships is the system of category customer relationship management (CRM) that is poorly used both among trade enterprises and their integration groupings. It provides for the possibilities to strengthen and build permanent relationships of an integrated trade network with its customers, relationships based on trust and loyalty. Introduction of this system to the practice of integrated networks management requires transformation of the hitherto networks' information resources in systemised sets of data related, first of all, to customers' purchasing behaviours and preferences, formation of income-generating customer portfolio, adjustment of the network's offer to the programme of mass individualisation and use of the IT tools assisting these relationships management.
