The finance department uses IT systems and software tools to automate accounting functions, organize data flows, and generate reports for managers. Even small businesses use accounting software, while mid-sized and large companies use more sophisticated enterprise resource planning (ERP) systems. ERP systems help plan resource use and integrate all company departments, allowing real-time information sharing to improve analysis and decision-making. Customizable reporting capabilities in these IT systems automate routine report generation to meet management's time-sensitive needs. Centralized databases also facilitate collaboration across departments globally to access and share necessary data. Access to comprehensive company information from IT systems supports the finance department in creating more accurate forecasts.
