A human resource information system (HRIS) uses software to electronically handle human resource activities like accounting, management, and payroll. An HRIS allows companies to more effectively plan, manage, and control HR costs without dedicating many resources to it. The main functions of an HRIS include benefits administration, payroll handling, employee records, recruitment, training, performance reviews, and attendance tracking. Maintaining an HRIS system helps gather, organize, and disseminate the information needed for efficient HR management. Key advantages are reduced data storage costs, faster data retrieval and processing, lower duplication efforts to reduce costs, timely access to accurate HR data, and improved analysis for better decision making.
