Computers are extensively used in accounting to process large volumes of data and provide accurate financial information to decision makers. Sophisticated accounting systems can handle general ledger, inventory, payroll, billing, and more. They update sales, purchases, stock levels, and determine reorder amounts. Computers also aid in costing, budgeting, production scheduling, accounts receivable/payable, and financial statement preparation and analysis to evaluate performance and predict future outcomes. Management accounting uses computerized financial data to assist planning and decision making.
