You set temp power first and wait two years for retention
You set temp power before the slab and you're still there at closeout. Retention is held against all of it, the whole way.
On a two-year build you're the first trade on and one of the last off, so your retention is withheld across the longest span of any trade on the job. The money held back on work you performed in month two sits there until final acceptance in month twenty-four. At ten percent retention against single-digit net margins, the retainage receivable on a long job routinely exceeds the profit the job will ever produce. The owner holds that cash while you carry the crews.
Three moves, in order
Step 07: Monthly cadence
Weekly bookkeeping, cost to complete, and one CEO report, on the same days every month.

What owners ask
Electrical contractor retention held for entire length of long project?
You set temp power before the slab and you're still there at closeout. Retention is held against all of it, the whole way. On a two-year build you're the first trade on and one of the last off, so your retention is withheld across the longest span of any trade on the job.

At ten percent retention against single-digit net margins, the retainage receivable on a long job routinely exceeds the profit the job will ever produce. The owner holds that cash while you carry the crews.
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.
Does this only happen in electrical?
Effectively yes, and that's why it has its own page. Electrical sits in electrical and technology and runs 9% net profit at $1M–$5M. The mechanism behind this problem has no real analog in the other 47 trades, so the general advice doesn't fit it.
Where do I start?
Age retainage by the date the work was performed, not by the job, so you can see how long each dollar has been held.
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.

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.

Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
