Corporate Purchasing specializes in the procurement of products and services that are utilized by the corporation itself, as opposed to the procurement of materials used in the manufacturing process. SGI uses state-of-the-art electronic commerce software to process purchase requisitions and send purchase orders to suppliers. Corporate Purchasing Buyers (who are located both in California and in the Midwest) receive purchase requisitions from employee requestors who may be located anywhere in the United States, including any of SGI's numerous field offices.

Corporate Purchasing's primary responsibility is to prepare Requests for Proposal, Requests for Information, and Requests for Quotation (RFPs, RFIs, and RFQs) when the complexity or dollar value warrants. Corporate Purchasing also is directly involved in supplier selection, supplier management, supplier problem resolution, make vs. buy analysis, and the processing of routine requisitions.
