This paper explores the key factors of an entrepreneurial project, with a special emphasis on the theoretical and practical aspects of investment and industry analysis. The theoretical part includes sources of financing, which is a key factor for the realization of any entrepreneurial venture. In the practical part, a bank loan was chosen as the source of financing for the project, which enables a detailed analysis of the project's effectiveness. The importance of an entrepreneurial project stems from the ability to identify and exploit business opportunities that can lead to the creation of new jobs, innovation and economic growth. Investment is necessary for starting and developing a business, and a well-conducted analysis of the industry helps in understanding the market, competition and potential risks. In this paper, an entrepreneurial project for the gluten-free pastry shop Kolačić was created, and the offer includes baked and unbaked cakes and cookies, coffee and squeezed juices from seasonal fruits. The project contains information about the entrepreneur, type of service, industry analysis, management and marketing. Financial data and efficiency evaluation are also presented. The target of the final paper is to determine the profitability of the project, i.e. whether it is worth investing money and whether there is a return on the invested funds. In the theoretical part, emphasis was placed on financing sources, and in the practical part, it was decided to use a bank loan as part of the capital source. In order to reduce the risk and predict the negative impacts, an analysis of the project's effectiveness was made. In the projection of the profit and loss account, it is evident that the company has been making a profit since the first year, which increases every year compared to the previous one. Using the payback period method, it was determined that the project pays 4 off, therefore, if this project is realized, the return of the invested funds can be expected in the second year.
