TRADE SERVICE · MARINE & SPECIALTY CLUSTER

FRACTIONAL CFO FOR MARINE CONTRACTORS.

QUICK ANSWER

We run the finance function for marine subcontractors doing $1M to $12M: 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.

Marine runs a floating spread that bills by the day whether the weather cooperates or not, so spread-day rates and a weather-standby cost code are the first two things we build. A barge, crane, and tug sitting through a blow costs the same as one working, which is equipment utilization at ten times the stakes of a dirt job. We put mobilization and demobilization on their own schedule-of-values lines, because getting a spread to site through tug transit, tow permits, crane rigging, and spud setup is a six-figure event on real jobs. Then we run the permit calendar as the cash calendar, since USACE Section 404, state Section 401, and environmental work windows decide when the spread can work at all.

WHERE MARINE LOSES MONEY

THE THREE THINGS THAT DRAIN THE 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 runs 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 runs on systems because at marine scale, paperwork discipline is cash discipline. (cfos-cash-control-system) ---

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.

Marine contractors at $1M to $5M net 6.5 percent on average, rising to 9.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 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 before taxes, the same basis CFMA reports on, so the two are directly comparable.
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.
