Accounting management systems (AMS) are information systems that collect and process financial data to provide reliable information to support decision making. They have several key components, including people, procedures, data, software, infrastructure, and controls. AMS collect transactional data, process it into useful reports, and provide controls to safeguard assets. They produce financial statements, managerial reports, and other documents. Information is organized into subsystems that correspond to key business cycles like revenue, expenditures, production, and financing. AMS provide benefits like increased efficiency, accuracy, forecasting ability, and compliance with financial reporting standards. Popular AMS software options include products from Oracle, Microsoft, Intuit, Sage, and SAP.
