To participate in a procurement, a prospective Vendor must complete Vendor Registration and view the solicitation through the Vendor’s Seller account. If you do not want to acknowledge this solicitation at this time, click Proceed, and its details will be displayed. A guide for the vendor registration process can be found under Important Links on the login page. Email bidpurchasing@ntta.org if you have any questions. IMPORTANT NOTE: If a Vendor does not register, the Vendor cannot submit clarification questions, receive notifications specific to a solicitation of interest, or be announced as being awarded a contract.
