Quote Comparator
Compare contractor quotes in one normalized table against local market rates, showing true totals, terms, scope gaps, hidden fees and questions to ask each vendor.
Built for buyers comparing contractor quotes, supplier bids or agency proposals before signing.
Why this work is hard
Buyers comparing contractor, supplier or agency quotes before signing spend hours on this by hand: finding the right sources, reading them, checking them against each other and writing up what matters. The work is repetitive, it is easy to miss something, and nobody can show where a claim came from.
Quote Comparator does that work as a GREP AI agent. It runs when you ask, and you can put it on a daily, weekly or monthly schedule. Every run delivers a spreadsheet, with every claim linked to its source.
