FRACTIONAL CFO FOR COMMERCIAL SUBCONTRACTORS · $1M TO $12M

THE JOBS ARE PROFITABLE. SO WHERE IS THE MONEY?

QUICK ANSWER

SPM The Construction CFO is the fractional CFO and construction accounting practice of Sulphur Prairie Management, LLC, serving commercial subcontractors and self-performing general contractors doing $1M to $12M in revenue across the United States and Canada. It runs CFOS, a 6 module financial operating system covering job costing built against your own estimate, WIP reporting, the cash flow cycle, working capital, and trade benchmarking, and it is delivered as one engagement with the bookkeeping and controllership included so nothing falls through the cracks. Rates start at $1,900 per month and every band is published on this page. Founded and run by Josh Luebker, who managed more than 150 commercial projects worth over $2.1B combined as a project manager and master electrician before he did this.

Most contractors who call aren't in trouble. They're busy, their crews are good, and their general contractors want to keep using them. What they can't get is a straight answer about where the margin went, and by the time anyone looks, the job has closed and the crew is two jobs down the road. That is a structural problem, and it has a fix.

DOES THIS SOUND FAMILIAR

THREE THINGS OWNERS SAY IN THE FIRST TEN MINUTES.

If one of these is close to something you've said out loud, the rest of this site is worth your time. If none of them is, it probably isn't, and that's a useful thing to learn in thirty seconds rather than on a call.

“The jobs are profitable and I still can't make payroll without watching the bank every Friday.”

Profit and cash don't move on the same clock. You fund payroll, material, equipment, and lower tier subs on day one, then bill at month end, then wait on an approval, then wait on retainage. The P&L is describing a month that's over. What you need is the next 13 weeks, dated.

Profitable but no cash

“I find out a job lost money at closeout, and by then the crew is two jobs down the road.”

Cost codes built off a generic template produce blended totals, so a code running hot is averaged against one running under and the whole job reads normal until it closes. Cost codes built against your own estimating assemblies make the same posted hours readable in week two, against the rate you bid.

Job costing that mirrors the estimate

“My bookkeeper is fine and my CPA is fine and nobody can tell me what my overhead really is.”

Because neither of them is looking at the job. Equipment, shop, and supervision usually sit in the wrong place on the P&L, which is why most contractors bid 10 percent overhead and run 18 to 28. Those dollars are spent on jobs and never charged to one, so every bid under-recovers until the rate carries them.

What your overhead really runs

WHAT MAKES THIS DIFFERENT

WE RAN THE WORK BEFORE WE RAN THE BOOKS.

Most fractional CFOs learned construction from a textbook. Both people here came off job sites, and that changes what gets built rather than just how it gets described. Job costing is aligned to how you estimate, so actuals compare to the number you bid. The forecast is built on your real pay application cycles and how each general contractor really pays. The overhead rate includes the equipment and the shop. And every monthly meeting ends in a short list of decisions rather than a report emailed over for you to interpret.

One engagement covering bookkeeping, controllership, and the CFO work together, so there are no scope gaps between three vendors blaming each other.
Benchmarks on 48 construction trades by revenue band, so your margin is measured against your own trade and size and not against construction in general.
60 days to fully operational, with books migrated back to the start of your last taxable year so the current year is complete and comparable.
About five hours a month of your time once it's running. You aren't going to be asked to learn accounting.
A two person firm on purpose. Josh Luebker takes every first call and runs every onboarding, and the VP of Operations runs the month after that. Nobody junior touches your file, because there's nobody junior to pass it to.
THE SYSTEM

CFOS, IN 6 MODULES.

CFOS is the Construction Financial Operating System, and it's the thing SPM installs. Each module answers one question an owner can't currently answer, and they're built in an order, because a cash forecast on top of bad job costing just gives you a confident wrong answer.

WHAT IT COSTS

THE RATE IS ON THE PAGE.

Nobody else in this category publishes one, and there's no good reason for that. A contractor comparing three firms shouldn't have to sit through three discovery calls to find out who is in his range. If the number below is wrong for your business you've saved a week, and if it is right the call is about the work instead of the price.

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.

What each tier includes

START WITH YOUR OWN TRADE

48 TRADES, EACH WITH ITS OWN NUMBERS.

Gross margin, net profit before taxes, and overhead rate for every trade by revenue band, with the CFOS target beside each industry average and the sources cited under every table. It is published in full, it needs no email address, and the whole dataset is published as JSON and CSV under CC BY 4.0 because a benchmark nobody can check isn't a benchmark.

COMMON QUESTIONS

FREQUENTLY ASKED.

CFOS is a 6 module financial operating system covering cash control, job profitability, the cash flow cycle, working capital, trade benchmarking, and the operating model itself. It is delivered as one engagement including bookkeeping, controllership, and CFO advisory, so there are no scope gaps between the layers. Job costing is built against the client's own estimating assemblies. ControlQore, a job costing and WIP platform, is set up and managed as part of the engagement and is not billed as a line item.
Commercial subcontractors and self-performing general contractors doing $1M to $12M in annual revenue, in the United States and Canada. It's not built for residential contractors, and it's not a bookkeeping-only service. Not payroll, not tax preparation, not audit or review engagements, and not a bookkeeping-only service. Clients keep their CPA for tax and compliance work.
$1,900 to $13,500 per month, priced on your last twelve months of revenue across 7 published bands, with the full table on this page and on the pricing page. The range inside each band is the three tiers, which differ by how much of the finance function comes off your desk. No payroll, and the job costing platform is never a separate line item.
60 days to fully operational, with books migrated back to the start of your last taxable year so the year you're in is complete and comparable. Job variance is readable in week two of live job costing. Your own time in the system runs about five hours a month after that.
No. Your CPA files the return and handles compliance, and they do it faster and cheaper against books that are already right. SPM is the layer between the field and that return: job costing, WIP, cash forecasting, overhead, and the monthly decisions that come out of them.
