Cash flow management is a key aspect of an enterprise's activity, as it is used to regulate all spheres of activity of a business entity, therefore issues related to the effectiveness of this process are of great relevance. The article substantiates the theoretical basis, develops a methodical approach and practical proposals for improving the cash flow management system. The object of the study was the company's cash flow management processes. The subject of scientific research was the theoretical, methodical and applied aspects of cash flow management of the enterprise, as well as modern methods of its optimization. An economic-mathematical model of multi-game optimization of the company's cash flows has been developed, which allows you to accumulate the necessary stock of cash assets in periods of high business activity and direct them in such a way that planned and necessary payments are made during the period of shortage of funds. The main criterion of the proposed model of cash flow optimization is the maximization of net cash flow from operating activities, which should ensure the development and expansion of the enterprise's activities on the basis of self-financing due to the growth of the areas of activity. According to the proposed model, the optimal balance of cash assets, insurance, compensation and current stock of cash assets for a specific enterprise is determined. The proposed model makes it possible to accumulate the necessary stock of monetary assets in periods of high business activity and to direct them in such a way that in the period of shortage of funds, planned and necessary payments are made, as a result of the implementation of the model, it becomes possible to avoid attracting credit resources and related expenses, while receiving additional profit from investing temporarily free funds.
