A plurality of orderers with their own code systems procures materials from companies (supply companies) with which the orderers have business relations. In this material procurement system, a name register master is provided for making correspondence between goods name codes provided by each of the supply companies and material codes of the orderers. When necessary materials are procured from the supply company, the orderer goods name codes are used for specifying the materials. Further, an order processor is provided. The order processor refers to the name register master, and combines orders of the materials with a same orderer goods name, if the same goods name of the supply company is in the name register master. The order processor also divides the orders and orders to another company by referring to the name register master, if the materials in a quantity beyond a predetermined number must be ordered.
