VERTICAL TRANSPORTATION CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY ELEVATOR CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Elevator margin is lost to three specific things: the annuity underneath, the proprietary wall, and the flat-priced portfolio. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Elevator contractors at $1M to $5M net 8.5 percent on the SPM 48-trade dataset, the highest floor of all 48 trades, rising to 10.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 12 percent. The distance between the trade average and the CFOS target isn't a pricing problem in this trade. It sits in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. Maintenance contracts at $500 to $1,200 per unit per month recur, compound, and explain the best net-profit floor in the 48-trade dataset. The operator who tracks per-unit contract P&L owns an asset; the one who doesn't owns a route.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Annuity Underneath

Maintenance contracts at $500 to $1,200 per unit per month recur, compound, and explain the best net-profit floor in the 48-trade dataset. The operator who tracks per-unit contract P&L owns an asset; the one who doesn't owns a route.

LEAK 02

The Proprietary Wall

OEM controllers, $10,000 diagnostic tools, and obsolescence declarations define the independent's serviceable universe, and every proprietary install shrinks it. Strategy in this trade starts with a map of what you can actually maintain.

LEAK 03

The Flat-Priced Portfolio

Full-maintenance pricing is an actuarial bet, and a portfolio priced flat across unit ages subsidizes the worst cars with the best. Callback rates per unit, repriced at renewal, are the trade's underwriting discipline. (cfos-job-profitability-system) ---

HOW CFOS FIXES IT

WHAT CHANGES IN THE FIRST 60 DAYS.

The maintenance annuity (why the floor is the highest in the 48)
The proprietary wall (independents vs the OEM ecosystem)
Callback economics (the contract inside the contract)
Install and modernization (the project wing on construction paper)
The inspection calendar (state-mandated recurring demand)

Industry figures are Elevator contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher, and the gross margin target is set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. Gross minus overhead equals net on every column, so the rows tie out.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Elevator contractors at $1M to $5M net about 8.5 percent on the SPM 48-trade benchmark dataset, the strongest floor of the 48 trades, rising to 10.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 12 percent. The floor is the maintenance annuity showing through the average; operators without a contract book ride well below it. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
They recur at $500 to $1,200 per traction unit per month, compound as the portfolio grows, and structure like insurance: the contractor assumes responsibility and controls the service cadence. Recurring books price at premium multiples across the adjacent trades, and elevator's version is the strongest annuity in construction.
It defines the serviceable universe: proprietary controllers and diagnostic tools (reported as high as $10,000) lock independents out of much equipment newer than about 15 years, and OEM obsolescence declarations steer buildings toward OEM parts and modernization. Independent strategy starts with mapping the open-architecture installed base and pricing within it.
Per unit, from actuals: callback rate, visit cost, and parts exposure by unit age and equipment type, repriced at renewal. Flat pricing across a mixed-age portfolio means the best cars subsidize the worst; age-banded pricing is the trade's underwriting.
Construction paper: long equipment leads with deposits, hoistway-readiness dependencies that idle crews, pay applications, and retainage. Bill deposits and stored equipment on the SOV, document readiness failures the day they happen, and treat the project wing's cash curve separately from the maintenance book's.
Sulphur Prairie Management, operating as The Construction CFO, publishes the 48-trade benchmark dataset these numbers come from. SPM's deepest specialization is 24 core commercial trades, and SPM works with elevator contractors who want the same financial system: onboarding, clean books, a maintained 13-week cash flow forecast, and monthly health reviews, with job costing simplified to what the business runs on. The full 48-trade benchmark reference exists so owners in every trade can measure against real numbers. ---
CFOS serves commercial elevator subcontractors doing $1M to $12M. Pricing starts at $1,900 per month for companies under $1M and runs to $13,500 per month at the top published band. Onboarding takes 60 days.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
Sixty days. We migrate your books back to the start of your last taxable year, set up ControlQore, and build your job costing structure from scratch. Fully operational in two months.
