MARINE & SPECIALTY CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY MARINE CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Marine margin is lost to three specific things: the spread that never sleeps, the window, and the sub-tier maze. Marine subcontractors at $1M to $5M have 24 percent gross and 7 percent net, against CFOS targets at $1M to $5M of 24.5 percent gross and 10.5 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Marine contractors at $1M to $5M net 7 percent, rising to 14 percent by $25M to $50M; the CFOS target at $1M to $5M is 10.5 percent. The distance between the trade average and the CFOS target comes out of operations in this trade, never out of pricing. It lives in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. Barges, cranes, and tugs bill by the day whether the weather cooperates or not, which is why marine overhead is 16 percent at the small end. Spread-day rates and weather-standby cost codes are the trade's version of equipment utilization, at ten times the stakes.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Spread That Never Sleeps

Barges, cranes, and tugs bill by the day whether the weather cooperates or not, which is why marine overhead is 16 percent at the small end. Spread-day rates and weather-standby cost codes are the trade's version of equipment utilization, at ten times the stakes.

LEAK 02

The Window

USACE permits, environmental windows, and tide tables decide when the work happens; the contractor decides only whether the cash plan matches. Peak-window competition alone can shift bids 10 to 25 percent.

LEAK 03

The Sub-Tier Maze

Under a prime on federal or port work, lien rights become Miller Act bond rights, deadlines change, and flow-downs govern. A $25M marine GC operates on systems because at marine scale, paperwork discipline is cash discipline. (cfos-cash-control-system) ---

HOW CFOS FIXES IT

WHAT CHANGES IN THE FIRST 60 DAYS.

Floating overhead (the barge bills whether it works or not)
The permit gauntlet (USACE and everyone else)
Sub-tier position on federal work (the query that found the site)
Mobilization at marine scale
The proof pages already exist (bonding and profit infrastructure)

Industry figures are Marine contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent after taxes or 3.5 points better than your trade's industry 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 margin and overhead are before tax figures and net profit is an average after taxes, so the three are separate published values. The three CFOS targets tie out: gross margin target minus overhead target equals the net profit target.

HOW THE NET PROFIT FIGURES ARE BUILT

Gross margin and overhead come from figures CFMA, Jones Maresca and other sources publish by trade and size, and they are before tax figures. Net profit starts from gross margin less overhead and is then adjusted for taxes and a few other expenses, so it is stated after taxes. It is published as its own average and is not calculated from the other two on the page.

CFMA reports net income before taxes, so a CFMA figure is higher than an after tax figure on the same business. CFMA's 2025 medians are 7.1 percent before interest and taxes and 6.7 percent net income before taxes. Read a net profit figure here against CFMA's with that difference in mind. The bands above the $10M to $25M band are published at runoncfos.com as a modeled extension of the same curves. They have not been reconciled against the licensed CFMA Benchmarker, so read them as a model and not as a survey result.

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. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

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. The onboarding fee is right here in the table.

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 and never in a report.

Your bookkeeper still does the books.

Executive

You stop touching the books.

Everything in Core, and we do the bookkeeping and the controllership as well. Your office stops answering coding questions and stops fixing a reconciliation that will not balance on the last day of the month.

We do the books. No payroll.

Strategic

Every job shows its margin while it is still open.

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 books, the job costing, and the software. No payroll.

What's included
COMMON QUESTIONS

FREQUENTLY ASKED.

Marine contractors at $1M to $5M net 7 percent on average, rising to 14 percent by $25M to $50M; the CFOS target at $1M to $5M is 10.5 percent. Marine earns the strongest gross margins in the earthwork-adjacent group and gives much of it back through 16 percent overhead, which makes spread-cost allocation the trade's defining discipline. Every net profit figure here is stated after taxes. CFMA reports net income before taxes, so a CFMA figure is higher than an after tax figure on the same business.

Because the equipment floats. Barges, cranes, tugs, spuds, and workboats have daily ownership cost whether the weather allows work or not, and the maintenance regime is saltwater-grade. Spread-day cost rates recovered through every bid are how the 16 percent gets paid for on purpose instead of by surprise.

They own the calendar. Environmental windows, tides, and sea states decide when the spread works, permits decide when the job can start, and peak-window competition can move bids 10 to 25 percent. The cash plan has to fund the spread through the standby days the window forces.

On federal projects there are no lien rights against the government; the Miller Act payment bond replaces them, with its own notice and suit deadlines that differ from state lien law. Calendar the bond deadlines at contract signing, review every flow-down clause, and keep certified payroll clean; the paperwork regime is the payment regime.

As its own front-loaded schedule-of-values line, with demobilization as a separate line at the end. Towing a spread to site is a six-figure event on real work; folded into unit prices it finances the job for the owner, and on canceled or suspended work it becomes an unrecoverable donation.

Spread-day costs by vessel, weather standby separately from productive time, mob and demob as their own codes, and permit-gated milestones on the cash forecast. A verified $25M marine GC operates on exactly that structure; at marine day-rates, untracked time is the most expensive kind.

A bookkeeper records history. Spread-day rates, weather-standby codes, Miller Act deadlines, and permit-gated cash planning are a control system, which is CFO work. SPM operates that financial control function for marine contractors. ---

CFOS serves commercial marine subcontractors doing $1M to $12M. Pricing starts at $1,900 per month for companies under $1M and goes up 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 do the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still open, 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.
