The role of enterprise resource planning (ERP) software in business is to integrate and manage core business processes in real-time. ERP systems combine various functions such as finance, human resources, supply chain management, and customer relationship management into a single platform, fostering seamless data sharing and collaboration across departments. This centralized approach enhances operational efficiency, provides actionable insights through data analytics, and improves decision-making. By automating routine tasks and streamlining workflows, ERP systems help businesses reduce costs and improve productivity.
