FAR and DFARS › FAR Part 17: Special Contracting Methods › Subpart 17.8
FAR 17.804 Procedures.
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
This section sets out procedures a contracting officer must follow when using a reverse auction service provider or conducting a reverse auction. It matters to contractors because it governs how auctions are run, including that offerors may keep lowering prices and may withdraw before the auction closes, and that offeror identities are generally not disclosed. It also addresses what happens if only one offeror participates.
Applies to: Contracting officers using reverse auction service providers or conducting reverse auctions
What it requires
- Conduct market research for available sources of reverse auction services
- Evaluate the fee structure for each reverse auction service provider
- Document the contract file that use of a reverse auction service provider is cost effective
- Not disclose the identity of the offeror(s), except the awardee's identity after an award resulting from the auction
