Sealed Bidding vs Negotiated Procurement

Sealed bidding was the historical default and still applies to a narrow set of construction and simple requirements, while negotiated procurement under FAR Part 15 now governs the vast majority of competitive federal awards.

Option A: Sealed bidding (FAR Part 14)
Option B: Negotiated procurement (FAR Part 15)
Bottom line: Sealed bidding is price-only and rare; negotiated procurement dominates modern federal buying
Best for: Federal bidders choosing where to spend limited capture budget

Key takeaways

Compare on outcomes — awards won — not on feature counts.
Factor total effort, not just price: proposal labor is usually the larger cost.
Most firms end up using both at different stages of maturity.
Decide based on your pipeline volume and how repeatable your content is.

Where they actually differ

Sealed bidding requires a firm-fixed-price award to the lowest responsive, responsible bidder with no discussions or negotiation after bid opening. Negotiated procurement allows discussions, technical and past performance evaluation alongside price, and award to the offer representing best value rather than lowest price.

When Sealed bidding (FAR Part 14) is the right choice

Expect sealed bidding mainly on construction contracts and simple, clearly specified commodity buys where price is genuinely the only meaningful discriminator.

When Negotiated procurement (FAR Part 15) is the right choice

Expect negotiated procurement for services, IT, and complex requirements, and build your proposal strategy around Section L instructions and Section M evaluation factors rather than price alone.
