WHY IRRIGATION CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Irrigation margin is lost to three specific things: the orphaned install, the freeze race, and the package seam. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Irrigation contractors at $1M to $5M net 5.5 percent on the SPM 48-trade dataset, rising to 8 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 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. Every system installed without a service agreement attached donates a 30-to-40-percent-gross-margin annuity to whoever answers next spring's call. The agreement signs at install, not at startup.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Orphaned Install

Every system installed without a service agreement attached donates a 30-to-40-percent-gross-margin annuity to whoever answers next spring's call. The agreement signs at install, not at startup.

LEAK 02

The Freeze Race

Startups and winterizations compress the year's service revenue into two windows capped by crews and compressors, and a missed blowout becomes a spring repair claim. Window capacity is the business plan.

LEAK 03

The Package Seam

Install rides inside landscape and sitework packages where sleeving, routing, and controller scope blur. Boundaries in writing before the trencher moves; the seam always leaks toward whoever documented least. (cfos-job-profitability-system) ---

Industry figures are Irrigation 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. The gross margin and overhead figures for this trade are derived from the nearest comparable trade in the same dataset, and were not measured directly.

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.

Irrigation contractors at $1M to $5M net about 5.5 percent on the SPM 48-trade benchmark dataset, rising to 8 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The gap between the benchmark and the trade's 30-to-40-percent-gross service work is usually orphaned installs and unpriced windows. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Because every installed system generates a recurring calendar (startup, checks, backflow testing, winterization) at service margins of 30 to 40 percent gross, and the valuation market rates recurring irrigation books above core landscape work. Attach the agreement at install; an orphaned system is an annuity donated to a competitor.
Most jurisdictions mandate annual testing of backflow preventers by certified testers, filed with the water purveyor: state-created recurring demand. Price it as a compliance product carrying the certification, calibration, and filing overhead, and route it with the rest of the service calendar.
Plan the two windows like harvests: startups and winterizations are capped by crew count and compressor capacity, so route density inside the windows sets the year's service revenue. Carry a shoulder-season reserve, presell the windows on the agreement calendar, and never let the freeze race find you unscheduled.
Whatever the paper says: sleeving under hardscape, mainline reroutes, and controller/electrical boundaries are the classic seams. Define them in writing before trenching, document field changes the day they happen, and price crossings and reroutes as change orders.
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 irrigation 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 irrigation 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.
