The systems have revolutionized practically all aspects of business processes in enterprises. They improve the processes by ensuring their integration. Data are entered into an ERP system only once and immediately afterwards they can be accessed through any of its modules, which makes them a valuable source of information on the enterprise. Integrating the financial and non-financial data, an ERP package gives new quality to the management of enterprise value. These features make ERPs particularly useful for management accounting processes and for specialists providing management information. This article seeks to answer whether following the implementation of an ERP package the enterprise’s management accounting system becomes more innovative and whether new, modern management accounting tools and methods are introduced. The ERP impacts on management accounting and its practices will be evaluated using six case studies involving enterprises owned by multinational corporations.
