Modern economic development trends such as globalization of markets, increasing competition, changing consumer demand, shortening life cycle of goods and technologies, increasing demands on their quality, and rising costs of used resources require executives and managers to find effective methods for managing the enterprise activity. Ensuring the competitiveness of enterprises under such conditions is impossible without the introduction of the latest management concepts, which necessitates changes and development of functional management, one of which is cost management based on the definition of new criteria for their classification. Classification of costs for management purposes should meet the main requirement – be based on signs that allow differentiating costs to manage them in various aspects. It creates preconditions for determining the level of costs by the volume of management, organization of planning, accounting, control, and analysis. The purpose of the article is to consider accounting and analytical, and managerial tasks of the classification of costs of industrial enterprises and their improvement. Methodology. The methodological basis of the paper is a set of methods and principles of scientific knowledge, general and special methods and techniques used in the study.
