FRACTIONAL CFO FOR TANK / VESSEL CONTRACTORS.

QUICK ANSWER

We run the finance function for tank / vessel 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.

Tank and vessel work splits along its own standards, so we split the books the same way. API 650 governs new welded tank construction and runs project economics, while API 653 mandates in-service inspection intervals and creates a condition-triggered repair market that recurs, and one blended P&L misprices both. We bill documentation-complete and plan the hydrotest as a logistics event, because sourcing, holding, and disposing of a structure's volume of test water stands between substantial completion and the check. Then we price turnaround work as its own class, since repair and alteration inside an owner outage runs premium-time labor by design and a late unit release is the trap that eats the window.

WHERE TANK / VESSEL LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Two-Code Book

API 650 new-build runs project economics; API 653 inspection-repair runs condition-triggered recurring demand. One blended P&L misprices both, and the recurring side is the stability the project side borrows against.

LEAK 02

The Hydro Gate

Qualifications, weld maps, NDE, and a structure full of test water stand between substantial completion and the check. Documentation-complete billing, with the hydro planned as a logistics event, is the trade's collection discipline.

LEAK 03

The Window Premium

Turnaround work compresses into owner outages where premium shifts are the plan and late unit release is the trap. Price the window explicitly and document the standby; the outage clock bills somebody. (cfos-job-profitability-system) ---

WHAT WE CHANGE.

Two codes, two businesses (650 new-build vs 653 inspection-repair)
The qualification and dossier economics (process piping's grammar, plate-sized)
The shutdown window (compressed-schedule premiums)
Plate, alloy, and the fab/field split
Confined space, coatings, and the entry-permit day

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.

Tank/vessel contractors at $1M to $5M net about 7 percent on the SPM 48-trade benchmark dataset, rising to 10 percent by $25M to $50M; the CFOS target at $1M to $5M is 10.5 percent. The curve runs strong for the tail because code work prices its qualifications, and the leaks are blended 650/653 books and windows priced at straight time. 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.
