FRACTIONAL CFO FOR IRRIGATION CONTRACTORS.

QUICK ANSWER

We manage the finance side for irrigation subcontractors doing $1M to $12M. You get job costing aligned to the way you estimate, a 13 week cash flow forecast, monthly WIP, and a CFO in the room every month. Pricing starts at $1,900 per month.

Irrigation installs a system and then decides, usually by accident, whether it owns the service book that follows. Service work has 30 to 40 percent gross margins on recurring contracts. Every install that goes out without an agreement gives that recurring work to whoever answers next spring's call, so the agreement has to be signed at install. We plan the year around two windows, spring startup and fall winterization, and size crew and compressor capacity against them. A missed blowout turns a $75 service call into a spring repair claim. Then we get scope boundaries in writing before the trencher moves. Inside a landscape package, sleeving, mainline routing and controller wiring always end up on whoever documented least.

WHERE IRRIGATION LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Orphaned Install

Install a system without a service agreement and you give away 30-to-40-percent-gross-margin recurring work to whoever answers next spring's call. Get the agreement signed at install.

LEAK 02

The Freeze Race

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

LEAK 03

The Package Seam

Install is part of landscape and sitework packages, where sleeving, routing and controller scope blur together. Put the boundaries in writing before the trencher moves. Whoever documented least ends up paying for the seam.

THE MATH

FROM 7% TO 10.5% NET.

At $1M to $5M, the average irrigation sub earns 22% gross margin and spends 15% of revenue on overhead. What's left is 7% net profit before taxes (Run On CFOS Trade Benchmark Reference). The CFOS target is 10.5% before taxes. That is the irrigation average plus 3.5 points, and never below 10%. The book CONTROL's 12% is the rule of thumb across trades. It is not the industry average.

Two changes get you to the target. Overhead comes down 1 point to 14%, and gross margin comes up 2.5 points to 24.5%, so 24.5 minus 14 leaves 10.5. The gross margin points come from the three problems above, once you price them and bill for them. On a $3M year, every point is $30,000.

HOW SPM FIXES IT

WHAT WE CHANGE.

These are the irrigation problems we put a number on first. Each one gets its own cost code, its own line on the schedule of values or its own line in the 13 week cash forecast, so you can read it in the monthly meeting while the job is still open.

GAP CALCULATOR

THE IRRIGATION GAP CALCULATOR. AVERAGE AGAINST TARGET, IN DOLLARS.

Put in your annual revenue. You get gross margin, overhead and net profit for irrigation contractors your size: the industry average and the CFOS target, in dollars a year. Nothing you type leaves this page.

Why aim for the target. An average is the middle of the pack: about half of companies do worse. And about 6 in 10 construction businesses close within 10 years (U.S. Bureau of Labor Statistics: about 40 percent of construction businesses opened in 2013 were still open in 2023). So the business in the middle is one of the ones that close. On those numbers, average is a business that closes within 10 years. That is why the CFOS target is a requirement.

The onboarding fee covers migrating your books back to the start of your last taxable year and getting you fully operational in 60 days. It's billed once, with your first invoice. It's the same for all three tiers, and it moves with your revenue band. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

Just want the setup? Onboarding only is the same onboarding work with no monthly service after it, one time, at the onboarding fee plus $2,000. Start a monthly engagement later and $2,000 counts toward it. It starts at $4,500, and the price for every band is on the pricing page.

The three tier columns are the whole price. Which one fits depends on how much of the work you want off your desk. No payroll. No hidden line items. The onboarding fee is right here in the table.

  • Online software only: QuickBooks, Sage, Viewpoint and similar. No VPN or hosted desktop.
  • Not in any tier: payroll, pay applications, collections on receivables.
  • Pricing valid through 2027.

COMMON QUESTIONS

FREQUENTLY ASKED.

Irrigation contractors at $1M to $5M net about 7 percent on the SPM 48-trade benchmark dataset, rising to 13 percent by $25M to $50M; the CFOS net profit target is 10.5 percent before taxes at $1M to $5M, the trade average plus 3.5 points. The service work earns 30-to-40-percent gross. The difference between that and the benchmark usually comes from orphaned installs and unpriced windows. Every net profit figure here is gross margin minus overhead, stated before taxes, the same basis CFMA reports net income on.

See the full benchmarks for every revenue band on Run On CFOS.

Usually it needs the CFO work, and a full time CFO is more than it needs. At $5M to $10M, irrigation subs average 9% net profit before taxes (Run On CFOS Trade Benchmark Reference), and the CFOS target is 12.5%. On $5M of revenue every point is $50,000, so that difference is worth $175,000 a year. A full time CFO costs $150,000 or more in salary alone. SPM's published price for $3.5M to $6.5M is $3,800 a month for Core to $8,300 for Platinum.

Because every installed system comes with a recurring calendar (startup, checks, backflow testing, winterization) at service margins of 30 to 40 percent gross. Buyers also value recurring irrigation books above core landscape work. Attach the agreement at install. A system without one is recurring work you gave to a competitor.

Most jurisdictions require annual testing of backflow preventers by certified testers, filed with the water purveyor. The state creates the recurring demand. Price it as a compliance product that covers the certification, calibration and filing overhead, and route it with the rest of your service calendar.

Plan the two windows ahead. Crew count and compressor capacity cap your startups and winterizations, so how tightly you route inside the windows sets the year's service revenue. Fund a shoulder-season reserve, presell the windows on the agreement calendar, and have every system scheduled before the freeze.

Whatever the paperwork 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 SPM 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 uses. The full 48-trade benchmark reference exists so owners in every trade can measure against real numbers.

Three tiers, and which one you are in depends on how much of the work you want off your desk. On Core we build your plan every month and your team does the work: 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. On Strategic we build the plan, track it and adjust it every month: our team does the bookkeeping and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. On Platinum we manage the money side for you every week: our team handles your bills and receivables the way an in-house controller would, and you approve every payment. We don't do payroll.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. You're fully up and working in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.

ControlQore is the job costing and WIP platform we use on the Strategic and Platinum tiers. It's built for contractors, costs less than the older tools, and has AI built in. We set it up and manage it, so you do not have to learn it. Core is the CFO work only, so it does not include the software.

A bookkeeper records what happened. We tell you what it means and what to do about it. We align job costing to your estimates, track WIP monthly, and hold a monthly meeting where you decide what to fix and who fixes it.

THE CHEAPER OPTION WORKS AND TAKES LONGER.

If price comes first, plenty of CFOs and bookkeepers can get your construction company results. It often takes the better part of a year.

If you're a trade contractor, a sub or a GC who wins work, keeps the crews busy and still can't figure out where the money goes, we get in the weeds with you. We change the processes that cost you money on every job, build the ones you're missing and give you the formula, so you see results in 60 to 90 days.

Our guarantee holds when you come to every meeting, do the process and keep a strong pipeline of work. We can fix how your work pays. We can't fix having no work.
