Communication is an important part of a private, social and corporate life of people and of a group (organisation). We recognise two types of communication: verbal communication, which can be oral and written, and the non-verbal one. In this paper we will elaborate business communication in non-profit organisations based on a case of non-profit organisation Ozana. The main difference between profit and non-profit organisations can be seen not only in the mission of the organisation, along with the means of financing and organisational structure, but also in the ways of communicating with the employees and other stakeholders. The main goal of non-profit organisations is providing aid and supporting individuals, groups and ideas. With these goals in mind, the Ozana organisation was founded in 1991, in order to help with the socialization and overall improvement of people's lives with permanent intellectual, physical and tactile disorders. Individuals who have certain physical and mental deformities are more challenged in the communication process than others considering that they find the process of ''reading'' non-verbal messages considerably harder. Internal communication in the organisation affects the work with the beneficiaries. The case study of non-profit organisation Ozana shows that its employees communicate organisational and agenda issues on daily basis. The quality of communication and maintainance of teamwork is strenghtened in creative workshops, which are organized every three months. Internal business communication of high quality also affects on the positive image of non-proftit organisation Ozana with the general public. The media have a crucial role in the building of Ozana's public image because they follow the work and activities of the organisation, as well as they help in promotion and collecting funds. The analysis of the non-profit organization Ozana shows the need for the improvement of relations with the media since the organisation's web and Facebook pages are not adequate for strenghtening its visibility in public.
