The aim and purpose of this paper is to point out to the quality of financial performance and efficiency of food retailers in Serbia, as well as measures for improvement in the future, based on theoretical knowledge and empirical analysis using AHP-TOPSIS methods. The problem of analyzing the financial performance of all companies, which includes trading companies, is very topical, significant and complex. Consequently, mathematical methods and models have lately been increasingly used. With this insight in mind, this paper investigates the financial performance and efficiency of food retailers in Serbia using AHP and TOPSIS methods. Of all the observed optimization criteria (cost of goods sold, operating costs, gross margin and net profit), the most significant was the cost of goods sold. The most efficient food retailer in Serbia is Aman. The Mercator-S Company is inefficient. In order to improve the efficiency of food retailers in Serbia, it is necessary to apply the Western business models (private brand, multichannel sales, organic food sales and others), the concepts of strategic management accounting and to strengthen the digitalization of business.

Under the influence of different factors, the dynamics of the size of the operating profit margin of food trading companies in Serbia varies from comparable global food retailers in various countries. Based on the obtained results of empirical research, we can also conclude that the operating profit margin of the leading food trading companies in Serbia is lower than the in analyzed comparable food retail trade companies from the developed market economies. It points to the conclusion that it is necessary to efficiently manage revenues, costs, profit, assets, and financial structure in order to improve the performance of food trading companies in Serbia in the future. In order to increase the operating profit margin, as a measure of long-term performance, it is necessary to manage the financial structure of the food trading companies in Serbia as effectively as possible.

U cilju ostvarenja određenih ciljeva (ekonomskih, socijalnih i okruženskih) neophodno je što efikasnije upravljati kapitalom u trgovini. Za te svrhe vrlo je značajno poznavati ključne determinante prinosa od kapitala u trgovini. U ovom radu se primenom određenih teorijsko-metodoloških saznanja istražuje uticaj ključnih (dvanaest) faktora na prinos od kapitala u trgovini Srbije za 2015. i 2016. Njihovo poznavanje je vrlo značajno primenom adekvatnih mera za poboljšanje efikasnosti upravljanja kapitalom (prinosa od kapitala) trgovine u Srbiji u budućnosti. (JEL klasifikacija: F65 L81 M40)
