The demand aggregation system includes buyer sponsored DealRooms, seller sponsored DealRooms, and multiple buyer and multiple seller sponsored DealRooms. Moreover, the demand aggregation system includes a customer relations management (CRM) package. In the CRM package, information on buyer and prospective buyers are loaded into a database that can include information such as: individual name; company name and address; email address; phone number; cell number; products purchased; volumes; time of purchase. Further the CRM package can be integrated with the demand aggregation system as well as a customer resource planning system (e.g., MRP, ERP).
