As per Wikipedia's definition, “Enterprise resource planning (ERP) is the integrated management of main business processes, often in real-time and mediated by software and technology.”

We’d define ERP as a fully-integrated platform that helps handle various aspects of a business, including accounting, procurement, manufacturing, project management, contract management, risk management, and warehouse management.

ERP systems enable a seamless data flow across the organization by tying all your business processes. This eliminates data duplication and provides a single source of truth.
