Wildcard Advantage Program

Procurement Environment

Northwestern supports a procurement environment based on the understanding that departments and schools are in the best position to determine what they need to run their programs. Learn more about Northwestern's procurement environment and strategic sourcing.

Preferred Vendors

  • Preferred Vendors are those that have been awarded a contract by Procurement and Payment Services for use by all departments and schools. We strongly encourage departments and schools to use Preferred Vendors.
  • Centrally Billed Preferred Vendors are Preferred Vendors who through a special relationship provide services that are available for central billing. Once enrolled in the program, you can charge the service to your Northwestern chart string. See the list of central bill services available for more details.

Bid Process

If there is no Preferred Vendor for a product or service needed or if a Preferred Vendor does not meet the needs of a department or school, competitive bids may need to be solicited. See an overview of the Bid Process for more details.

Procurement Methods

See the following pages for information on Northwestern's Procurement Methods.

Requisitions (REQ) are budget-checked and require approval in NUFinancials prior to being sourced into a Purchase Order (PUR) and sent to the vendor. See Approvals/Workflow for information.
