A 30-day quote can't hold a nine-month buyout
You bid the equipment off a quote good for 30 days, then bought it out eight months later at the new price sheet, with no second vendor to shop it to.
Any other trade with commodity exposure can at least re-bid the buyout against a second supplier and claw some of it back. You can't, because the devices are keyed to the panel and the panel comes from one authorized distributor at one price. On a two-year school or hospital, that same exposure repeats on every release you take.
The size of it
A 6% to 12% move on 40% of contract value is 3 to 5 points of gross margin gone on a scope that was bid at 22.
Two things move underneath the bid while you wait for approvals. Plenum-rated cable, the FPLP 18/2, 16/2 and 14/2 shielded you pull by the thousand feet, is copper wrapped in an FEP fluoropolymer jacket, and FEP runs its own supply cycle, so plenum cable can jump in a year copper sits still. The other is the manufacturer's price sheet, which resets annually and isn't negotiable at the counter. On hard bid public work the escalation language gets struck before you ever see the contract, and the longer the gap between bid date and buyout, the more of that move you're holding by yourself.

What fire alarm owners ask
Fire alarm equipment price went up between bid and buyout?
You bid the equipment off a quote good for 30 days, then bought it out eight months later at the new price sheet, with no second vendor to shop it to.
What does it cost?
A 6% to 12% move on 40% of contract value is 3 to 5 points of gross margin gone on a scope that was bid at 22.
What do I do first?
Print the distributor quote's expiration date on the bid form and state plainly that the equipment price holds for that window and reprices after it.
What are fire alarm contractors supposed to be making?
Fire alarm runs 24% gross margin, 16% overhead and 8% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points above it. The CFOS target is 11%.
Which part of the system fixes it?
The step is number 04, estimating system. The estimate maps one to one onto the job cost codes, so variance means something the day it appears. It comes from chapter 4 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.

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