Three things, done well. That’s the whole pitch.
We catch the leaks in your subs’ invoices.
We review supplier and subcontractor invoices line by line and catch overcharges, scope creep, and bad math before they hit your margin. Recent finds: $96K and $4,831 in overcharges caught — both flagged before payment.
We produce your bids.
White-label, on your letterhead. Plumbing-led, with steel and earthwork in active rotation — Division 22, fixtures, rough-in, gas, medical gas, storm & sanitary; structural steel takeoffs; cut/fill earthwork.
48-hour turnaround on standard scopes.
Faster than your in-house estimator. Cheaper than hiring one. No PTO, no benefits, no bad weeks.
Start with one bid. No retainer required.
Per-bid is how new clients land. Capped retainers come later, once real volume justifies one — never as the first commitment.
Single-trade, standard bid form. Quantities cited to plan sheets; gaps logged as written RFIs.
Multi-trade or complex single-trade. Validator gate on every quantity. 48-hour turnaround on standard scopes.
Full proposal with audit-grade documentation: takeoffs, citations, RFI log, confidence tiers. Built for GC review.
Capped monthly retainer starting at $5,000/mo for up to ~4 standard bids. Volume cap protects both sides — additional bids billed at per-bid tier. Convert from per-bid once steady volume justifies it.
Line-by-line review of every supplier and sub invoice you receive. Flagged-discrepancy report before you cut the check. $4,831 hard overcharges + $96K flagged for one client in the first audit window.
