CASE STUDY — MARINE CONTRACTOR

$2.3M TO $5.5M VALUATION.

QUICK ANSWER

A $13.5M marine general contractor had strong revenue but no job costing, so a buyer couldn't see real profit. After building job costing and clean reporting, net profit doubled from 7% to 14% and valuation rose from $2.3M to $5.5M in 9 months — $3.2M more value on the same revenue, crews, and work.

This marine general contractor wasn't in trouble — crews were experienced, GC relationships were strong, and work kept coming. But when the owner considered selling, the number wasn't there. Four accounting staff and still no job costing, no per-project reporting. A buyer doesn't pay for revenue; they pay for provable, sustainable profit, and there was no way to prove it. Building real job costing and tightening unreviewed spending doubled net profit and unlocked $3.2M in business value the owner didn't know he already had.

THE SITUATION

A $13.5M MARINE GC. NOT IN CRISIS.

A $13.5M marine general contracting company came to SPM not in crisis. Crews were experienced, GC relationships were strong, and work kept coming. The owner wanted to sell — and when he looked at what the business was actually worth, the number wasn't there.

THE PROBLEM

FOUR ACCOUNTING STAFF. STILL NO ANSWER.

Four accounting staff and still no job costing, no per-project reporting. Revenue looked strong on paper. But a buyer doesn't pay for revenue — they pay for provable, sustainable profit, and there was no way to prove it.

Every job felt profitable in the moment. Nobody could say by how much, or which jobs were actually carrying the business.

THE DIAGNOSIS

MARGIN WAS THERE. NOBODY COULD SEE IT.

The diagnosis came down to a missing Job Profitability system: with no per-project cost tracking, real margin was invisible even to the owner. Spending that had never been scrutinized — subscriptions, vendor relationships, material purchasing — was quietly compressing net profit well below what the business's actual performance supported. The fix required both job costing structure and a disciplined operating rhythm around it, which is where the Working Capital System came in — sizing and protecting the capital the business needed as clean numbers surfaced.

THE INTERVENTION

WHAT CHANGED, PROJECT BY PROJECT.

Month 1: Built the job costing structure from the ground up, tracking cost at the individual project level for the first time.
Month 1–2: Tightened spending across subscriptions, vendor relationships, and material purchasing that had never been reviewed.
Month 2–3: Put a clean, twice-monthly reporting system in place for every active job.
Months 4–9: Documented nine consecutive months of clean, provable profitability ahead of the sale conversation.
THE OUTCOME

THE NUMBERS, NOT THE FEELING.

7→14%
Net Profit on Same Revenue
$917K
Margin Recovered Per Year
$2.3M→$5.5M
Business Valuation
$3.2M
More Value, Same Revenue & Crews

Net profit went from 7% to 14% on the same revenue, recovering $917,000 a year that was already inside the business. At 7% net with disorganized books, the business was valued at $2.3M on a 2.5x multiple. At 14% net with 9 months of clean, documented profitability, valuation rose to $5.5M on a 3x multiple — $3.2M more in business value on the same revenue, same crews, same work.

Total time from first call to the $5.5M valuation: 9 months. That's 9 consecutive months of clean, documented profitability — the specific asset a buyer was willing to pay a higher multiple for.

WHAT THIS MEANS FOR OTHER CONTRACTORS

DOES THIS SOUND FAMILIAR?

Contractors who recognize this pattern usually share these traits: strong revenue and steady work, but margin that's never been rigorously tracked per project; multiple accounting staff without a real job costing system underneath them; vendor and material spend that hasn't been reviewed in years; and a business worth more than its books currently prove — especially relevant if a sale or exit is on the horizon.

If that describes your business, the value you're missing isn't hypothetical — it's sitting in spend and margin no one's measured yet. See how CFOS applies this specifically to marine contractors on the Marine Operating System page, or book a free diagnostic call.

COMMON QUESTIONS

FREQUENTLY ASKED.

The $13.5M marine GC had strong revenue and steady work but no job costing or per-project reporting despite four accounting staff. When the owner considered selling, the business's provable profit didn't support the valuation he expected.
The diagnosis centered on missing per-project job costing. Unscrutinized spending on subscriptions, vendors, and materials was compressing net profit well below what the business's real performance supported.
Net profit rose from 7% to 14% on the same revenue, recovering $917,000 a year. Business valuation rose from $2.3M to $5.5M in 9 months — $3.2M more value on the same revenue, crews, and work.
Yes, particularly for marine contractors preparing for a sale or exit where documented, provable margin drives valuation. Job costing and clean per-project reporting are core to the CFOS Marine Operating System.
