This paper aims to analyze the impact of the types of innovations in increasing the sales of Kosovo's enterprises. The findings of this paper confirm the hypotheses that organizational innovations, product/process innovations and marketing innovations have a positive impact on increasing the level of sales. This empirical research was conducted with enterprises in Kosovo, so the main limitation of this research is the non-inclusion of enterprises of Albania, Montenegro, North Macedonia, Bosnia and Herzegovina, etc. The involvement of enterprises from these countries would provide a broader picture of the research issues for transition countries. This empirical research is of particular importance because it studies the impact of types of innovation on increasing the sales level of enterprises in transition countries. Kosovo suffer from weak enterprises sector and underdeveloped entrepreneurship sector. Without the development of an innovative system of the private sector and the entrepreneurial sector, Kosovo cannot overcome the transition process. Therefore, this paper could be a reference point for the government policies of Kosovo, which should support all enterprises in the development of all types of innovations.
