For Our Suppliers
Purchasing Services provides value added customer service to our campus community by acquiring goods and services at the best overall cost and value. Procurements funded by federal agencies that exceed the Simplified Acquisition Threshold (SAT), as defined in 2 C.F.R. §200.88, are required to have solicitations advertised on our website. The following link allows all suppliers and contractors easy online access to solicitations, including Invitation for Bids (IFB's) Request for Proposals (RFP's), Request for Quotes (RFQ's), and Addenda. All interested suppliers and contractors must follow the instructions in the solicitation to be considered for award. If you need assistance or have any questions, please contact the Purchasing Agent or Contracting Officer responsible for the solicitation.
