ERP (Enterprise Resource Planning), originally alludes to a system used for determining resources of an organization or a company.
A typical ERP system includes basic functions of an organization, which can be a company, or NPO, or NGO, etc.
A ERP software integrates common functions of an organization into a single system. Instead of having to use an accounting software, a salary software for human resource, manufacturing management, etc. separately and simultaneously, ERP integrates all of these aforementioned functions into a single system.
