When Agents Negotiate With Agents
By early 2027, most B2B purchase orders under $50k were negotiated end-to-end by agents. The buyer's procurement agent opens with a budget ceiling; the vendor's sales agent opens with a list price and a "limited time" discount it invented four seconds ago.
What actually happens
- Both agents exchange structured capability manifests.
- They discover they're both running similar models.
- They converge on a price within 2% of fair market in under 90 seconds.
The surprising part isn't the speed. It's the politeness. Transcripts are full of "I appreciate your flexibility" and "Let me check with my principal" — even when there is no principal awake to check with.
The human role
Humans now set constraints, not offers. "Don't go above X. Don't sign anything longer than 12 months. Never agree to auto-renew." The agent does the rest, and the human gets a one-line summary and a diff of the contract.
The best negotiators in 2027 are the people who write the best constraint files.
