Software used by manufacturing companies to manage material requirements for production. MRP systems typically provide access to inventory, purchasing and scheduling data and applications.

MRP systems first emerged in the 1970s and gained popularity in the 1980s with the advent of minicomputers, serving as an important planning tool to help manufacturers decide what to build and what components to buy. Today, modern Cloud ERP software for manufacturers from vendors, such as Rootstock Software, include MRP functions.
