An important feature of globalization and integrated development of the economy is the use of information technology and accumulated information in other forms of production to improve their efficiency. On the other hand, one of the problems of modern information and analytical support is duplication of accounting operations, incomparability of information, the need to obtain information online. The article is dedicated to study of modern advances in information technology and the rationale for their use in management activities for more in-depth analysis, modeling and forecasting on the basis of timely and complete information about the controlled processes. Information technologies used in accounting have gone through several stages of development: use of Microsoft Excel spreadsheets, introduction of specialized software products, use of integrated ERP enterprise management systems and cloud technologies. If there are a number of advantages, they also have disadvantages associated with the risks of loss and distortion of information; fragmentation and low quality of data; lack of automated generation of accounting and analytical information, taking into account the time value of money; focus on the needs of existing accounting methods; lack of integration into the international accounting system. New stages in development of information technologies have been identified: blockchain technology, machine learning, artificial intelligence, which allow minimizing these problems. It is shown that the prospects for development of accounting are associated with increasingly complicated accounting models based on modern digital technologies. This leads to an increase in the volume and complexity of information flows, an increase in the risk of loss and distortion of information. Research and comparative analysis of modern information technologies allowed to substantiate a model of informational and analytical business support, including three subsystems: accounting and analytical support, participants in business processes, and a single information space where, under the conditions of the blockchain technology, it is possible to monitor and manage business online anywhere in the world.
