The main goal of this Bechelor thesis was to develop a business plan for a corporate body- a limited liability company in the field of production and selling of chocolate and chocolate products. The work is divided into three chapters. The first one defines the basic concepts and a business plan. The second chapter analyzes the individual parts of the business plan into details focusing on PEST analysis, competittive analysis, SWOT analysis, financial analysis and other methods. The third part is devoted to the practical implementation of the business plan for a specific company. In the end I summarise all the theoretical and practical knowledge with reference to their strengths and weaknesses derived from the analysis described in the work.
