The run is done? Give me the short version — what should I look at before I sign?
Worked for 1h 47m ›
Done — $618,829.39, everything traced. Three things worth your eyes:
• Classroom run lengths: ±4 LF per room × 48 rooms ≈ ±$14K swing
• Reception desk: may be 1 desk not 2 — if duplicate, remove $900
• WD-01 wall base: if confirmed millwork scope, add ~$1.52M

TAKEOFF-AUDIT.HTMLINTERNAL
Millwork estimating — Takeoff audit
Every measurement sourced and flagged. Shows scale, calibration, variance, and rate sources.
Review recommended — provisional lines or coverage gaps
Firm = proven on the drawings. Provisional = a defensible default, flagged until proof arrives.
32 FIRM LINES
Every firm quantity links to its evidence and its recompute proof — a printed dimension or a measured run at verified scale.

The shift

Your bid volume is one
person's calendar.

Today
One estimator, one pile of tools.
Forty to eighty hours a bid, estimators tell us.
Three bids out in a good week. The rest declined, unpriced.
With MillOS
The estimate comes back in hours, with proof on every line.
Your estimator verifies, corrects, signs.
The next package runs while they review this one.
The goal: your bid volume set by how fast your estimator can review, not by how fast they can measure.

What you get

An estimate a client can receive.

The priced estimate.
Your format. Totals that add up to the dollar.
The marked-up drawings.
Every item pinned on the sheet it came from.
The proposal, on request.
Client-ready page and PDF.
The honest list.
Assumptions, open questions, and any price we had to ask you for.
Control

It shows its work.
Then it waits for you.

Nothing leaves without a signature from someone whose name means something on a bid.
✓The estimate stops at review. Your reply is the sign-off.
✓"Line 12 is 8 feet, not 6" fixes that line and nothing else.
✓A correction never erases an approval.
?No price in your book? It asks. It does not guess.

Proven where estimating is hardest.

01We started in commercial millwork, one of the most judgment-heavy trades there is.
02Working estimators grade every estimate against their own, line by line, on live bids.
03On a recent one: every item in the estimator's own workbook found, nothing invented.

Built for shops that price from drawings.

Who it's for
Subcontractors who bid from a GC's package — commercial millwork today, more trades next. Five to a hundred people, one or two estimators, more invitations than you can price.
The math
Estimator time per bid today~$2,400
With MillOS, review only~$400
Bids through the same desk4–6×
Pricing
Flat monthly, per company — no per-bid meter running while you decide what to price. Final pricing is being set with early partners; your first package is free either way.
🔒
Your data stays yours.
Your drawings, your price book, your wins and losses are isolated to your company. They are never shown to, or used to price, anyone else's work — including ours.

The next bid package does not have to cost a week.
