Stop wasting estimating hours on bids you were never going to win.
BidSignal is bid/no-bid software for Division 27 and 28 contractors. It reviews every invitation to bid against your trade, territory, capacity, and GC history. Then it shows Bid, Review, or Decline with the reasons.
14-day free trial. No credit card, no automatic charge when it ends.
Works on the bid invitations you already receive. Forward an ITB, get a decision. BidSignal does not find or sell new bids.
Built for low-voltage. Not every trade at once.
Catches Div 26 vs 27/28 scope splits
Generic bid tools treat every division the same. BidSignal reads your ITB like a low-voltage estimator would — flagging when cabling, fire alarm, security, or AV scope is buried in Division 26 or split between trades, before it costs you on the number.
Know which GCs actually award you work
Log your bid outcomes and BidSignal tracks your win rate and bid value by GC over time. Stop pricing jobs for GCs who use you for numbers and never award.
Works on the ITBs you already get from ConstructConnect, BuildingConnected, PlanHub, or straight from GCs.
