Through the work, and all with transparent and collected facts, analyzes, definitions, examples and knowledge, the main goal is to get to know, remind and present the immanent topic of today - customer relationship management. The basics, new information as well as all-time definitions of basic concepts and segments in this set of relationships and business situations were explored. The idea is to present sales today with all the characteristics, starting from the basics, nature, through the way and in sequence to the description of the sales profile and on the other hand, the key customer. Equally, the motive is to break down the center of the topic and the title of the work into parts of the content on the connection between process, management, finding, business intelligence and relationships, both with the buyer and the seller and primarily primarily sales as such. Closely related would be the planned research, conducted directly by surveys, according to a certain ranking, types of customers and complex characteristics of this type of business.
