You don't have a WIP schedule
If someone asked today which open jobs are over and by how much, the honest answer would take a week to produce.
The WIP schedule is the only report that tells you whether the work in progress is earning what you sold it for. Without one, you find out at closeout, which is the one point in a job where you can no longer do anything about the number. Every month you run without it, you're managing off the bank balance and a feel for how the jobs are going. Neither of those tells you a job is eating its margin while it's still open.
Three moves, in order
Step 07: Monthly cadence
Weekly bookkeeping, cost to complete, and one CEO report, on the same days every month.

If someone asked today which open jobs are over and by how much, the honest answer would take a week to produce. The WIP schedule is the only report that tells you whether the work in progress is earning what you sold it for. Without one, you find out at closeout, which is the one point in a job where you can no longer do anything about the number. Every month you run without it, you're managing off the bank balance and a feel for how the jobs are going. Neither of those tells you a job is eating its margin while it's still open.
Which part of the system fixes this?
The step is number 07, monthly cadence. Weekly bookkeeping, cost to complete, and one CEO report, on the same days every month. It's drawn from chapter 7 of CONTROL: The Construction Financial Operating System.
Is this normal for my trade?
Across the 48 trades in the benchmark reference, net profit at $1M–$5M averages 7% before taxes. If you're well under that and this page describes your month, the two are usually the same story. The published average tells you where the pack sits, and your own job costing tells you where you sit, which is the number that pays payroll.
Where do I start?
Build the schedule from cost to complete, gathered from the people running the jobs.
Can I fix this without touching anything else?
You can try, and it doesn't hold. Step 07 depends on step 03, overhead calculation and step 04, estimating system and step 05, software and bookkeeping alignment and step 06, project management. Install it ahead of those and it produces numbers nobody trusts, which is worse than the problem you started with.
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.
