Your Shop Drawings Are Payroll With No Pay App
You spent five weeks on drafting, submittals, and veneer samples, none of it reached a pay application, and the architect decided when that window closed.
A trade that mobilizes the week it wins starts producing installed, billable work immediately. A millwork shop has to design the product before the product exists, because it doesn't exist until your drafter draws it and an architect signs it. That makes engineering a production department with its own payroll sitting entirely on the wrong side of the first pay application.
The size of it
Weeks of drafter and PM wages come out of your own cash on every job, and they double when the drawings come back for a second review. The money leaves in month one and turns into revenue in month four, so the job reads like a loser right up until install week.
No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. It reports inside NAICS 238350 Finish Carpentry, so there's no millwork and casework margin figure to put in this box. The 48 trades that do publish average 7% net profit at $1M–$5M before taxes, which is the nearest reference point worth anything here.
Millwork gets engineered in full before a single sheet gets cut. Shop drawings, finish samples, veneer submittals, and hardware cut sheets all go up for review, and the design team holds the clock on every one of them. Remmert is blunt that there's no correct number of days for an architect's approval, and the lead time on your panel and hardware buy starts at approved, not at awarded. Every drafting and PM hour inside that window is real payroll charged against a job showing zero percent complete on the GC's schedule of values. Then the drawings come back marked up and you fund a second round out of the same pocket.

What millwork and casework owners ask
How to cost shop drawing and submittal hours before the job is billable?
You spent five weeks on drafting, submittals, and veneer samples, none of it reached a pay application, and the architect decided when that window closed.
What does it cost?
Weeks of drafter and PM wages come out of your own cash on every job, and they double when the drawings come back for a second review. The money leaves in month one and turns into revenue in month four, so the job reads like a loser right up until install week.
What do I do first?
Give engineering its own cost code and its own phase in the job cost structure, so drafting and submittal hours hit the job instead of overhead, where they vanish.
Are there published benchmarks for millwork and casework?
No, and this site won't print one. No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. In the surveys it rolls into NAICS 238350 Finish Carpentry, so the closest honest reference is the 48-trade table, where net profit at $1M–$5M averages 7% before taxes. Read that as the neighbourhood, and read your own job costing as the answer.
Which part of the system fixes it?
The step is number 01, job cost structure. Seven cost categories and three levels of granularity, built so the estimate and the ledger use the same words. It comes from chapter 1 of CONTROL: The Construction Financial Operating System.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
