For successful business, it is very important to have different financing options for entrepreneurial ventures, as well as for small and medium-sized entrepreneurs to be as familiar as possible with them. Due to the limited possibilities of traditional sources of financing, entrepreneurs are increasingly looking for new, modern ways of financing. However, entrepreneurs are not sufficiently informed about them and do not take advantage of them to a sufficient extent. Accordingly, a study was conducted whose goals were to investigate the available modern sources of financing for small and medium-sized enterprises in the Republic of Croatia, to investigate the knowledge of entrepreneurs about them, to find out the frequency of using modern sources of financing, and to create recommendations for entrepreneurs in the Republic of Croatia on how to access these sources. A survey was conducted with 154 entrepreneurs and persons involved in company management. It was found out that entrepreneurs are familiar with traditional sources of financing much more than with modern ones. Furthermore, it was confirmed that a very small proportion of entrepreneurs use modern sources of financing. It was also shown that the state should participate more in supporting the sector of small and medium enterprises. It was also concluded that a great deal of support is needed for entrepreneurs through mentoring, education and better access to information. s
