It is important to define the financing of an enterprise and understand its issues, differences and the importance of each enterprise. Funding in the widest sense can be understood as one of the basic functions of all businesses. The process of financing is a dynamic process of obtaining, investing and earning profit. Financing decisions are made by the management or financial manager. Efficient business operations and asset management can lead to cost savings, timely collection, late payment deadlines, increased liquidity and solvency, increases in profits, etc. Otherwise, there could be financial damage that results in an increase in loss, fall in stock prices, fall in liquidity and solvency, bankruptcy, liquidation of company, etc. By financing the company, it becomes a financial system in which the money is continously converted into other goods and vice versa. This paper represents how much financing is needed for maintaining business. Managers have a major role in securing sufficient funds for financing, as well as great responsibility towards shareholders to increase their wealth and improve the company and all its aspects, taking into account profitability, liquidity, solvency, etc. They have to manage between long-term, medium-term and short-term financing, both their own and others, both internally and externally, as shown in this paper.
