The NASA Solutions for Enterprise-Wide Procurement (SEWP) contract gives federal agencies and their approved contractors access to the latest Information Technology, Communication, and Audio-Visual (ITC/AV) solutions and services.

SEWP funds itself through usage fees and supports more than 50,000 orders a year.
SEWP VI is a multiple-award GWAC. Learn more at www.sewp.nasa.gov.

No documentation for the order selection is required to be submitted with the order. All such documentation is to be maintained by the issuing procurement office.
The Contractor shall not market, quote or otherwise offer for sale, any IT Solutions not listed under this contract, until the said solutions are included in the SEWP database of record, and available to all Government end-users.
If the Government issues a Request for Information (RFI) as part of market research, the Contractor may provide items not yet listed on their SEWP contract as part of a market research quote if:
If the Government issues a Request for Quote (RFQ) or a Market Research Request (MRR), the Contractor may only respond with items available on their Contract and the price of each item shall be the no greater than the price in Attachment F SEWP database of record at the time the quote is issued. If the Contractor has insufficient items on their contract to fully respond to the Formal RFQ, the Contractor must respond with a No Bid.
Unless the RFQ specifically allows for partial quotes, the Contractor must respond fully to all requirements specified in the RFQ.
When submitting a quote to a government end-user, the contractor must clearly state the length of time the quote is valid. The contractor shall honor any order submitted within the stated time period of a quote.
When responding to an RFI or RFQ issued from the NASA SEWP RFQ on-line quoting system, the Contractor must respond as outlined in Attachment C: Contract Holder User Manual (CHUM). Contract Holders are prohibited from using Government information posted on the NASA SEWP Contract Holder Only Page, such as RFQs, RFIs, etc., for purposes other than proposing on SEWP requirements. This includes Contract Holders providing third parties with SEWP information and requirements for the purpose of assisting companies, that are not SEWP Contract Holders, with providing unsolicited proposals to meet agency requirements already posted to the NASA SEWP RFQ on-line quoting system.
Federal customers may request a quote for services through the NASA SEWP Quote Request Tool (QRT) or by contacting Windsor Group LLC’s SEWP Program Support team directly. Customers should provide a description of their requirements, anticipated scope of work, and any relevant supporting documentation. Windsor Group LLC’s designated representatives are available to assist with quote requests and questions regarding services offered under its SEWP VI contract.
