Every Offer, Counter & Term —
One Living Thread.
OfferStack turns scattered negotiation emails into a structured deal timeline. Version history, concession tracking, term diffs, and AI-powered recaps — so you never lose context mid-deal.
Negotiations happen across 50+ emails. Context is lost by email 10.
Brokers juggle multiple counterparties, shifting terms, and verbal agreements buried in email threads. By the time a deal is close to fixing, nobody remembers who conceded what, when, or why. Mistakes happen. Deals fall apart.
Scroll through 50 emails to find the last rate. Copy terms into a spreadsheet. Hope nothing changed since your last read. Miss a counter-offer because it was buried in a reply chain.
Every offer, counter-offer, and term change is auto-captured into a structured timeline. Concessions are tracked. Diffs are highlighted. AI recaps the full negotiation state in one click.
