The purpose of this final paper was to get to know the company and the cash flow of the company. The enterprise constitutes the fundamental economic object of the study of the economy. Without companies and entrepreneurs, not only would the conditions for the existence of the economy exist, but it would not be possible to live in the society we have created. The importance of companies for the functioning and development of society, economy, business, intellectual and technological knowledge is becoming more and more noticeable. In order for a company to exist at all, it must have money. The money available to the company can be obtained through its own sources of financing or through other sources of financing. Own sources are a cheaper variant of financing, but unfortunately only own sources are often not enough for the company to achieve the set goals. When internal resources are not enough, the company resorts to external sources of financing, which the company itself comes to more expensive, but it is enough to meet the needs of the company and enable it to achieve its goals. The goal of every company should be to create such a business where it is possible to maintain a constant rhythm and gradually expand to other markets and be self-sustainable, in the company must be strong and developed enough to finance its own operating costs, while investing generally have to find other ways of financing. Securing money for investment is the main task of a financial unit in a company. The financial managers of which the financial unit consists must be able to secure money for investments in a timely manner. In addition to financial managers having to provide money to finance projects and expand businesses, they still need to monitor the flow of money for investments, be responsible for any additional costs created during business and must know how to choose good investments from bad ones. Business and investment alone are not possible without costs, and operating costs are a necessary part of a company's business. Without costs, the company would not be able to function. In addition to costs and raising money, the company must pay attention to the political, social, cultural and competitive environment in which it operates. Although companies are currently the best in the market, they are forced to invest in their development and technology and monitor competition at all times, otherwise weaker competing companies may overtake it with new innovations or technology and occupy its market share. The most important decisions made regarding the financing of projects and other needs of the company are made by the financial function, this function has the task of providing the company with the necessary financial resources, which requires great knowledge and experience of financial managers.
