• Cost accounting is one of the main sources of information for the management in the company. A correctly designed cost accounting system may address the most important issues in order to support effective and successful decision-making, which among others include price building, efficiency measurement and profit evaluation. In order to enable the full functioning of the system the company should ensure that the system is designed according to the company’s size, operations and processes, as well as information needs. For Testo Sensor GmbH the optimization of cost accounting system became essential, as the information it provides at the moment is not sufficient and reliable for decision-making. Obviously, the reason for this is that the system was not correctly and thoroughly designed at the times of the company foundation. Therefore, the goal of current paper is to develop and adjust the cost accounting system to the company’s operations in order to fulfill the information needs. In order to reach this goal the following objectives were defined:  to analyze the current state of cost accounting system of Testo Sensor  to reveal its weaknesses and incompatibilities  to address these incompatibilities by developing the improvements and possible optimization potentials In order to fulfill these objectives, the review of the German and English literature on the current topic was made in order to identify possible approaches and methods and provide a theoretical background for solutions of the existent problem. In addition to this, a number of interviews was held with the employees of Testo Sensor, as well as the parent company. Finally, the exact data for 2011 – 2015 for cost analysis was taken from the company’s database systems and other documentation. The result of the current paper represents a number of the optimization potentials, which relate to all elements of the cost accounting system. In addition to this, a proposal for implementation of cost center planning and control, which currently is not implemented in the company, was designed. The optimization proposals were developed with the consideration of the theoretical methods applied in German companies, as well as the company’s particular needs and possibilities.
