This final paper “From an idea to the realization of a business venture; a start-up example of an integrated childcare service” is the result of looking forward to solve a personal problem - finding a quality care for children and a personal desire to harmonize private and business life. The final paper consists of a theoretical part explaining the entrepreneurial process from the idea and the decision of an entrepreneurial career through the observed opportunity, industry and market analysis, the business plan to the entrepreneurial venture, and the empirical part showing the business plan of the integrated childcare service in Osijek for children up to 10 years of age. The risk analysis, created with the help of the SWOT analysis, showed that the biggest weaknesses and threats of the venture are a major initial investment for equipment and higher service prices, as well as administrative barriers and the prolongation of the economic crisis with the emigration of young families. A marketing plan, based on the SAVE model, has demonstrated that this venture can build its competitive advantage on the following characteristics and values: individual adaptation to each client, high flexibility of working time, educated and professional staff, high quality equipment and toys, safety in children's care, as well as the openness to co-operation and business transparency. Due to the specific nature of the business activity it is about, related laws are accompanied in this final paper as well: the Law on Nannies and the trade law, as well as relevant rulebooks. „Being an entrepreneur and creating a new business venture is just as child raising - it takes longer, it takes more effort than you ever could imagine, and it's terribly difficult and painful to get out of that situation. Thank God that you can not easily disassemble either of these situations.“ (Hisrich, Peters, Stephard ,2011:5)
