Although control appears as the last managerial functions, after planning, organizing, framing and managing them all, it connects them all because it ensures supervision of the actions of the enterprise on the way to achieving the set goals. Control is a dynamic activity, and the manager must possess decision-making skills in order to react appropriately in a particular situation. Control is carried out through four steps: standards, performance measurements, standards and performance comparisons, and performance evaluation and corrective action, if necessary. Control in manufacturing enterprises is most often carried out through the control of operations and financial control. Financial statements and analyses provide the necessary information to management of the company, to make better business decisions. One of the important activities in the Republic of Croatia is the metal processing industry, which has been growing steadily over the last few years. Primary research was conducted on the company Bravarija Mirt d.o.o. with the aim of finding proposals for improving the control system. The paper outlines the benefits for the observed company from the use of financial control mechanisms in order to improve the decision-making system and consequently increase the performance of the business.
