The characteristic of the generally accepted methodological approaches to assessing the value of enterprises, namely the profitable, costly, comparative approaches by highlighting the advantages and disadvantages of each of them, disclosed the diversity of methods within each approach. It is the presence of the limitations of each approach that sets the vector for the further development of the methodological foundations for assessing the value of enterprises in modern economic market environment. Based on the analysis of recent research by domestic and foreign scientists there is expediency of using the integrated approach as a comprehensive methodological support for the process of assessing the value of enterprises is substantiated; it is a branched system of assessment methods.

This sequence of actions serves as a basic "link" between the stage of choosing methodological tools for assessing the value of enterprises and the stage of its implementation. The growing role of the integrated approach, which is reflected in the number of its application in economic research, this is clearly a positive trend in the development of the methodological foundations of the process of assessing the value of enterprises in modern economic conditions, because it implies obtaining more accurate results when carrying out calculations, and thus allows making the assessment procedure targeted, which corresponds to modern trends in the development of methodological tools for assessing the value of enterprises.
