An ERP system, it is also known as an ERP suite, is a collection of enterprise resource planning software that communicates with one another and shares a database. Typically, each ERP module focuses on a single business sector. You can mix and match modules to fulfill your requirements. Popular beginning places include finance, sales, human resources, and logistics. Modules dedicated to certain industries, such as manufacturing and retail, are also available. Each module is often licensed independently, allowing businesses to pick and choose the features they want, as well as add on and grow as needed.
