Throughout this paper, general information on the concept of the sale of services will be presented. More recently, there has been an increasing emphasis on services and how difficult it is to describe and fully measure their value. The big problem that arises when defining this term is that it is a ratio between the great role and importance, and on the other hand it is intangible and therefore it is not possible to fully evaluate its benefit or cost. Services often vary in nature as their sales are influenced by a number of factors that this paper presents. Apart from the fact that the services are charged, the interesting thing about them is that in each sale of service material things do not have to be used. In addition to defining the term services, the paper also illustrates the impact of the marketing mix on services. In order to define the sale of services, the paper analyzes the business of the company whose primary activity is the sale of services.
