An Enterprise Resource Planning (ERP) System is one of the most advanced business applications used by large organizations to manage finance, HR, inventory, sales, procurement, customer relationships, and business operations from a single platform.
Companies such as manufacturing firms, retail businesses, hospitals, educational institutions, and multinational corporations use ERP systems to automate business processes and improve efficiency.
