Built by an estimator
for estimators
BidShield is the pre-submission review platform that catches what The EDGE, STACK, and Excel can't — built after 12 years of commercial roofing estimation.
Why BidShield exists
Estimating software tells you what's in your bid. Nobody tells you what's missing from it.
A missed mechanical curb section on a $3M job costs $47,000. A missed addendum costs $31,000. Wrong submittal requirements: $22,000. These aren't edge cases — they happen every week, on bids that looked complete before submission.
BidShield is the last line of defense before you submit. It runs every bid through 18 phases and 100+ check items — the same review a veteran estimator runs in their head, systematized so nothing gets missed when you're busy.
What BidShield does
Works alongside your existing estimating software — not instead of it.
18-Phase Pre-Submission Review
Every bid runs through 18 phases covering scope verification, mechanical systems, addenda, submittal requirements, takeoff reconciliation, and bid form completeness. Each phase has 5–8 specific check items.
Bid Readiness Score
Each bid gets a 0–100 readiness score that updates as you complete phases. Know exactly where you stand before you submit — not after you win and discover what was missing.
Takeoff Reconciliation
Cross-reference your SF quantities against drawings automatically. Flags area discrepancies before your bid goes out — not during a GC back-charge conversation.
40-Item Scope Gap Checker
Runs 40 common scope gap items against your bid — mechanical curbs, edge metal systems, drain compatibility, expansion joints, warranty scope, liquidated damages clauses.
The EDGE tells you what's in your bid.
BidShield tells you what's missing from it.
No replacement required. Use it on any bid, with any estimating software you already use today.
