Owners and management nowadays face a dynamic environment, where everything is prone to sudden changes, and controlling is necessary for a successful survival of the company. Controlling provides professional support to management. Today's companies face problems where demand is much lower than the supply of products and services, and the environment is extremely dynamic. The task of controlling is to focus on the future and to choose quality strategies for successful business. Controlling in Croatia was accepted very late, but it tends to grow and be more present. Tokić d.o.o. is a leading regional distributor of auto parts and accessories with over 300,000 items from the world's 300 most famous manufacturers for all types of passenger cars and light trucks. It employs about 600 workers, and the controlling department influences the business success of the company. On a monthly basis, it reports to the management on what has been achieved and planned. The paper will present the concept of controlling and its significant impact on the company. Controlling works closely with various departments within the company to contribute to more efficient and effective management work. The purpose is to show what role controling plays in the Tokić company and what good modern practices can serve as an example to controllers in other companies.
