Business operations today largely depend on the changes taking place on the market and on the process of globalization itself. In addition, it is crucial that companies have their own goals that they want to achieve in the near and distant future. In order to achieve goals, it is crucial to follow the services that lead to the successful operation of a company. The services of a company are combined into one structure, which is called an organizational structure, which today almost every company has. The organizational structure is also called the skeleton of the organization, i.e. the company. The topic of the work is the role and significance of the financial service implemented in the financial function of the company. The company's financial service monitors the use and placement of financial resources that are essential for the business and success of a company. Also, it takes place in dependence and with accounting jobs. Accounting and finance complement each other, and without the implementation of one in the other, there is no successful management and the key to the survival of any company. Without a well-organized business in financial resources, which form the backbone of the business itself, there will be no profit, which is crucial for the very beginning of the business. The activities carried out by the financial department include a wide range of tasks that include the record of decision-making activities that are crucial to the completion of financial statements and that help in making strategies and further business development in a company. Data related to finances should be collected on a daily basis by the bookkeeping department, or in some companies by the department. The financial service cooperates in the preparation of the budget for each year as well as in the preparation of the organization of further spending of the budget.
