FRACTIONAL CFO FOR EXCAVATION CONTRACTORS.

QUICK ANSWER

We manage the finance function for excavation 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.

Excavation sells cubic yards per hour, so we build the cost system around production rate rather than job totals. Rates get tracked per operator, per machine, and per soil class, because without that split a losing job reads identically to a winning one until the money is gone. Ownership cost goes into the bid at a real rate, roughly $200 a day for a CAT 330 parked against industry idle rates near 30 percent, and hired haul gets watched hard since idle trucking subs bill $85 to $125 an hour each while a site isn't ready for them. Then unit-price discipline and daily documentation cover the changed-conditions dispute, which one $630,000 excavation subcontract took all the way to the Fifth Circuit.

WHERE EXCAVATION LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

Production Blindness

Excavation sells cubic yards per hour. When production rates aren't tracked per operator, per machine, per soil class, the estimate and the field never reconcile, and losing jobs look identical to winning ones until the money is gone.

LEAK 02

The Ground Lies

Soil class changes, rock is found, groundwater rises, and quantities move; the cost is spent before the change order is signed. A $630K excavation subcontract at the Fifth Circuit proves the dispute is real. Documentation and unit-price discipline are the difference between a claim and a donation.

LEAK 03

One Bucket, One Margin

A single utility strike can erase a job's profit through repair bills, fines up to $10,000 for repeats, and GL sublimits that cap below the damage. The locate, the tolerance zone, and the hand-dig are financial controls, not just safety rules.

THE MATH

FROM 7% TO 10.5% NET.

At $1M to $5M, the average excavation sub earns 21% gross margin and spends 14% of revenue on overhead, which leaves 7% net profit before taxes (Run On CFOS Trade Benchmark Reference). The CFOS target is 10.5% before taxes, the excavation average plus 3.5 points and never below 10%, where the book CONTROL's 12% is the rule of thumb across trades. It is not the industry average.

The target takes two moves. Overhead comes down 1 point to 13%, and gross margin comes up 2.5 points to 23.5%, so 23.5 minus 13 leaves 10.5. The gross margin points come from the three leaks above, priced and billed, not absorbed. On a $3M year, every point is $30,000.

HOW SPM FIXES IT

WHAT WE CHANGE.

These are the excavation problems we put a number on first. Each one gets its own cost code, its own line on the schedule of values or its own line in the 13 week cash forecast, so you can read it in the monthly meeting while the job is still open.

Why aim for the target. An average is the middle of the pack: about half of companies do worse. And about 6 in 10 construction businesses close within 10 years (U.S. Bureau of Labor Statistics: about 40 percent of construction businesses opened in 2013 were still open in 2023). So the business in the middle is one of the ones that close. On those numbers, average is a business that closes within 10 years. That is why the CFOS target is a requirement.

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, and it moves with your revenue band. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

Just want the setup? Onboarding only is the same onboarding work with no monthly service after it, one time, at the onboarding fee plus $2,000. Start a monthly engagement later and $2,000 counts toward it. It starts at $4,500, and the price for every band is on the pricing page.

The three tier columns are the whole price. Which one fits 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.

  • Online software only: QuickBooks, Sage, Viewpoint and similar. No VPN or hosted desktop.
  • Not in any tier: payroll, pay applications, collections on receivables.
  • Pricing valid through 2027.

What Core, Strategic and Platinum each include is on the pricing page.

Prevailing wage note: Excavation work often comes from public bids, which means certified payroll and wage classifications have to line up with the job cost record. ControlQore holds the classification against the cost code, so the certified report and the job cost report come from the same data, and your office stops keying the same numbers twice every week.

COMMON QUESTIONS

FREQUENTLY ASKED.

Excavation contractors at $1M to $5M in revenue net 7 percent on average, rising to 10 percent at $5M to $10M. The CFOS net profit target is 10.5 percent before taxes at $1M to $5M, the trade average plus 3.5 points, and it rises with the average at each larger band. The gap is usually in untracked production rates, haul-off cost changes, and iron that bills nothing. Every net profit figure here is gross margin minus overhead, stated before taxes, the same basis CFMA reports net income on.

Usually it needs the CFO work, not a full time CFO. At $5M to $10M, excavation subs average 10% net profit before taxes (Run On CFOS Trade Benchmark Reference), and the CFOS target is 13.5%. On $5M of revenue every point is $50,000, so that distance is worth $175,000 a year. A full time CFO costs $150,000 or more in salary alone. SPM's published price for $3.5M to $6.5M is $3,800 a month for Core to $8,300 for Platinum.

Because the trade pays you last and charges you first. Equipment payments and fuel are due daily, trucking subs bill weekly, and the receivable is paid 60 to 90 days later, minus retainage. Add one rock surprise or one failed compaction test and the quarter's cash is spoken for.

It turns on the 811 locate and the digging discipline. Skip the locate or dig through the marks and the excavator owns the damage; mismarked lines can shift fault to the utility or locator. Fines start around $2,500 and repeat violations reach $10,000, and many GL policies sublimit underground facility damage below the real repair cost.

Classify soils in the bid, include unit prices for rock and unsuitable material, and tie both to a written changed-conditions clause. The cost of extra spoil gets spent before any dispute resolves; the paper trail is what turns a surprise into a paid change order instead of a donation.

A CAT 330 class machine costs $150 to $200 per hour fully loaded and roughly $200 per day in ownership cost even parked. Every bid needs an ownership-and-operating rate per machine; fuel-and-grease-only rates leave the ownership cost with the owner.

About 13 percent of revenue at that size, trending toward 11 percent as revenue grows. For construction as a whole, Jones Maresca and Company's 2025 Performance Benchmarks put total indirect cost at 8 to 15 percent of revenue and CFMA's 2024 Construction Financial Benchmarker reports SG&A at 11.8 percent across all respondents, and both of those are averages rather than an excavation figure. /construction-overhead-rates-by-trade has the excavation rate for your revenue band. Excavation overhead goes unseen in the yard: lowboys, service trucks, mechanics, and the shop all have to be recovered by the working iron.

It depends on machine class, soil, and haul pattern, which is the point: track it per job, per operator, per soil class, and compare against the estimate weekly. Production tracking is the single highest-leverage number in the trade, because everything else prices off it.

A bookkeeper records history. Production-rate pricing, equipment ownership rates, changed-conditions claims, and utility-strike reserves are a control-system problem, which is CFO work. SPM operates that financial control function for excavation contractors.

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. Strategic is where every job shows its margin while it is still open: a bookkeeper we choose does the books and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. Platinum is where you approve and the money side gets handled: a controller we choose handles your bills and receivables the way an in-house controller would, and you approve every payment. No payroll. No scope gaps.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. Fully operational in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.

ControlQore is the job costing and WIP platform we use on the Strategic and Platinum tiers. Purpose-built for contractors, more affordable than legacy tools, and AI-infused. We set it up and manage it, so you do not have to learn it. Core is the CFO work only, so it does not include the software.

A bookkeeper records what happened. We tell you what it means and what to do about it. We align job costing to your estimates, track WIP monthly, and hold strategic accountability meetings so problems get fixed and not merely documented.

WHAT ELSE BREAKS IN EXCAVATION

MORE PROBLEMS WE PUT A NUMBER ON.

Compaction failures and rework

Backfill compaction cost tracking

A failed proctor or density test means re-excavate, re-place, re-test, on the contractor's dime, while the schedule loses days. Backfill rework is unpaid production.

Dewatering and groundwater surprises

Groundwater dewatering costs

Groundwater shows and the job stops until pumps, wellpoints, or trenching changes get priced. The cost is real, immediate, and rarely in the bid.

Rock, spoil, and the changed-conditions dispute

Soil classification cost codes

The ground never matches the report. D2 Excavating v. Thompson Thrift started as a $630K excavation subcontract, produced far more spoil than planned, and ended at the Fifth Circuit with a judgment for the sub above half a million dollars. The cost is spent before the dispute starts.

THE CHEAPER OPTION WORKS. IT TAKES LONGER.

If price comes first, plenty of CFOs and bookkeepers can get your construction company results. It often takes the better part of a year.

If you're a trade contractor, a sub or a GC who wins work, keeps the crews busy and still can't figure out where the money goes, we get in the weeds with you. We change the processes that cost you money on every job, build the ones you're missing and give you the formula, so you see results in 60 to 90 days.

Our guarantee holds when you come to every meeting, do the process and keep a strong pipeline of work. We can fix how your work pays. We can't fix having no work.
