This paper deals with the topic of corporate communication using the case study of the company Elektrocentar Petek d.o.o.. Corporate communication refers to the managed communication activities of profit organizations with the aim of building identity and maintaining a positive reputation of the company. An overview of theoretical approaches and definitions of the term corporate communication is given, and the most important areas of a corporate corporation are highlighted. Since it is responsible for all communication activities, it is necessary for the corporation to have a uniform appearance and for all levels to speak the same language. The basis for such action is the development of a communication strategy that follows the business strategy of the organization. The company Elektrocentar Petek d.o.o. is a medium-sized company and combines various activities in energy, construction and trade. The organization does not have an established corporate communications department that would be responsible for all communication towards interested publics and stakeholders. Therefore, it does not communicate business successes and projects in a clear way, nor is there organized internal communication that would disseminate important information timely and accurately throughout all organizational structures, which can lead to communication noise and unclear instructions from top to bottom. In this sense, it would be useful to establish a corporate communication department that would create a communication strategy and carry out communication activities.
