Finished in March, Retention Releases Next Winter
Two to six weeks of your work sits inside an eighteen to twenty four month build, and the retention doesn't move until the whole project closes out.
Retention is a slice of your contract held against a completion date you can't influence. Because clearing is the first scope on the ground, the stretch between your last day and the project's last day is the widest on the job, and it repeats on every project you take. A routine contract term turns into a permanent block of your cash sitting inside other people's buildings.
The size of it
A meaningful piece of every contract sits as a receivable for a year or more, funded out of your own cash while the machines that earned it are already worn down on the next tract. Most owners in this trade can't state their total retention balance, so it's missing from the forecast and missing from the conversation with the bank.
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 238910 Site Preparation, so there's no land clearing 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.
Retention releases at substantial completion or project closeout, which has nothing to do with the day you finished. Your first day on site is day one of the entire project, ahead of mass grading, utilities, and the slab. So two to six weeks of physical work gets held across an eighteen to twenty four month build. No trade on that job waits longer relative to the time it spent on the ground. You cleared the tract in March and the money comes in when the building opens.

What land clearing owners ask
When do i get retention released if i only cleared the site?
Two to six weeks of your work sits inside an eighteen to twenty four month build, and the retention doesn't move until the whole project closes out.
What does it cost?
A meaningful piece of every contract sits as a receivable for a year or more, funded out of your own cash while the machines that earned it are already worn down on the next tract. Most owners in this trade can't state their total retention balance, so it's missing from the forecast and missing from the conversation with the bank.
What do I do first?
Build a retention schedule listing every job, the amount held, the date you finished, and the project's expected closeout, and update it monthly.
Are there published benchmarks for land clearing?
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 238910 Site Preparation, 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 05, software and bookkeeping alignment. Live job costs inside thirty seconds, with the bookkeeping cadence that keeps them true. It comes from chapter 5 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.
