Best and final offer

A best and final offer (BAFO) is a final round in a competitive negotiation: the buyer shortlists the leading bidders, invites each to submit its last and best terms — typically price, sometimes schedule or scope concessions — and awards from those submissions. By rule the BAFO is final: submitted terms are held, and attempts to improve them afterwards are refused or disqualify.

Strategically, a BAFO invitation is information. Being shortlisted means the buyer is seriously considering you; the invitation timing, questions asked, and concessions requested telegraph what the competition actually turns on. The common failure is panicking the number down: a BAFO round does not mean you are losing on price, and a discount the buyer would never have demanded is margin donated for nothing. The disciplined response prices the round as its own decision — walk-away, target, and opening already computed before the invitation arrives. Preparation tools that model pricing against the evaluation grid, like pubsec.pro's free generator, help most exactly here, where the last number is the one that counts.
