North Carolina General Statutes Chapter 143. State Departments, Institutions, and Commissions § 143-129.9. Alternative competitive bidding methods

(1) Reverse auction.--For purposes of this section, “reverse auction” means a real-time purchasing process in which bidders compete to provide goods at the lowest selling price in an open and interactive environment. The bidders' prices may be revealed during the reverse auction. A reverse auction may be conducted by the political subdivision or by a third party under contract with the political subdivision. A political subdivision may also conduct a reverse auction through the State electronic procurement system, and compliance with the procedures and requirements of the State's reverse auction process satisfies the political subdivision's obligations under this Article.

(2) Electronic bidding.--A political subdivision may receive bids electronically in addition to or instead of paper bids. Procedures for receipt of electronic bids for contracts that are subject to the requirements of G.S. 143-129 shall be designed to ensure the security, authenticity, and confidentiality of the bids to at least the same extent as is provided for with sealed paper bids.
