Section B: Supplies or Services and Price/Costs

An official change an agency issues to a solicitation after release, correcting an error, answering a Q&A, revising requirements, or shifting the proposal due date. Solicitations typically require offerors to acknowledge each amendment for their proposal to remain responsive, so missing one can put an otherwise compliant submission at risk.

The final proposal revision an offeror submits after the government closes discussions in a negotiated procurement, incorporating any last changes to price, terms, or technical approach. Once BAFOs are in, the contracting officer evaluates them against the stated criteria and makes the award decision; no further revisions are typically allowed.

A DoD competitive acquisition method, authorized under 10 U.S.C. 3458, that solicits innovative commercial products or services through a general solicitation instead of a traditional RFP. Submissions go through a streamlined, merit-based review rather than full FAR Part 15 negotiation, and any resulting award must use a fixed-price contract type.

A preview version of a solicitation that an agency releases before the official RFP, giving industry a chance to review draft requirements, terms, and evaluation criteria and submit comments or questions. Agencies typically use it to surface ambiguities, gauge competitive interest, and refine the final RFP before formally issuing it.

The contracting officer's formal written notification to a selected offeror that its proposal has been chosen for award, typically identifying the contract number, value, and scope. It signals selection but isn't itself the binding contract: that's created once the award document is executed by both parties.
