What is ERP?
ERP (Enterprise resource planning) is the management information systems that integrate and manage many of the businesses associated with the production operations and distribution aspects of a company's production of goods or services.

ERP systems are occasionally called back office, as they indicate that the customer and the general public do not have access to them; likewise, it is a system that deals directly with suppliers, not just establishing relationship management with them (CRM). However, progressively the ERP software tends to occupy all the spaces in the organization, absorbing the CRM functions. In fact, the largest CRM producing companies in the world have been absorbed by ERP software companies in the last ten years.
