With the expression, “Business Intelligence” we refer to intelligent technologies that may help companies improve their performances and have better possibilities to survive and develop. Anyway, in this regard, we sometimes have a double negative impression, namely that on one side there is a certain lack of practical indications on how to apply this in everyday companies’ life and, secondly, that it is often not taken into due consideration the extremely reduced size of companies, the limited entrepreneurial competences and the scarce availability of technologies. In this paper, apart from highlighting the role of Business Intelligence in practice, we try to find a way to apply it also in small size companies focusing on two critical aspects, namely customer’s profitability and their satisfaction level that, especially if considered in their reciprocal interaction, may have a great impact on companies’ outcomes though using simple technologies.
