Entrepreneurship and its importance come from economic activities and specific business functions that are capable of developing an idea and making use of available resources to create a new product or service and successfully placing it to the market. The entrepreneur is responsible, and he is thus credited with transforming the original idea into an thought out product or service, knowingly taking over all the risk and investing capital. The skill of this venture and the elaborated business plan depends on how the product will be accepted, how much the end user will be satisfied and how much the entrepreneur will have financial benefits from the idea itself and its realization. The business plan is the first and very important step in realizing that idea. It is a written document that contains elaborate analysis of investment in business, systematic presentation of planned goals and activities in a specific, mostly multi-year period. It is designed to anticipate future events in a business environment and to reduce the degree of risk, time spent, resources and other factors that may adversely affect the business. In this final paper, an entrepreneurial project is presented on the example of music store, primarily focusing on vinyl records. The main objective is to determine whether the project is financially viable or acceptable. The reason for choosing this theme lies in the fact that today, given the development of technology and market trends, the increasingly represented purchase of music content through digital download from the Internet, subscribtions to various "streaming" music services is slowly affecting the option of owning physical music content, either in the form of author's music albums, compilations of selected songs or professionally recorded performances from individual concerts or events. At the same time, given the above reasons, there is a growing need for content possession, but in physical form as originally intended. Despite this, it is hard to resist the impression that in Croatia, especially in Karlovac, there is a lack of stores that will satisfy demand for this type of content and is the main motive for launching this entrepreneurial idea.
