CIVIL & EARTHWORK CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY SWPPP / EROSION CONTROL CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

SWPPP / Erosion Control margin is lost to three specific things: the $56,460 clock, the quarter-inch trigger, and the route ledger. All three are measurable, and all three are invisible without job costing that reads against the estimate.

A verified $5.2M erosion control contractor went from $24K to $1,105,000 in net profit at a 30 percent margin by installing per-site job costing and cash control. The distance between the trade average and the CFOS target isn't a pricing problem in this trade. It sits in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. Stormwater penalties run to five figures per day per violation, stop-work orders ride along, and the paper trail is the only defense. The SWPPP contractor sells that protection, which means the contractor's own documentation system is the product.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The $56,460 Clock

Stormwater penalties run to five figures per day per violation, stop-work orders ride along, and the paper trail is the only defense. The SWPPP contractor sells that protection, which means the contractor's own documentation system is the product.

LEAK 02

The Quarter-Inch Trigger

A 0.25-inch storm obligates 24-hour inspections across every site at once. Surge capacity priced at routine rates is a donation; the rain-event rate class is how the sky's schedule gets paid for.

LEAK 03

The Route Ledger

Dozens of small sites live or die on cost per site: drive time, BMP burn, inspection minutes. A verified $5.2M erosion contractor went from $24K to $1,105,000 net at a 30 percent margin on exactly that ledger. (cfos-job-profitability-system) ---

Industry figures are SWPPP / Erosion Control contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher, and the gross margin target is set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. Gross minus overhead equals net on every column, so the rows tie out.

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.

The CFOS target at $1M to $5M is 11 percent net, and the ceiling is higher than most trades believe: one verified $5.2M erosion control contractor runs a 30 percent margin after rebuilding from $24K of net to $1,105,000. In a per-site recurring business, margin comes down to route density and cost per site.
The permit holder wears the fine, and at up to $56,460 per day per violation plus stop-work exposure, the fight afterward is about whose documentation failed. A SWPPP contractor with complete inspection logs, corrective-action records, and photo trails is the client's defense; one without them is the defendant's co-star. Documentation is the product.
As their own rate class, above routine inspection pricing. A quarter-inch storm triggers 24-hour inspections across every site simultaneously; that's emergency surge work, and pricing it at route rates donates the hardest hours in the business. Put the trigger, the window, and the rate in the contract.
Run a per-site P&L: inspection minutes, drive time, BMP materials, and rework against the site's contract price, rolled up by route. The $24K-to-$1,105,000 turnaround on this site's flagship case was that ledger installed and acted on; sites and routes that lose get repriced or released.
Split the book into divisions: installation (construction-season), inspection contracts (recurring), and maintenance (recurring). The recurring lines carry the winter, the seasonal reserve carries the gap, and the divisional P&L shows whether growth should buy more crews or more contracts.
A bookkeeper records history. Per-site P&Ls, rain-event rate classes, compliance documentation systems, and seasonal reserves are a control system, which is CFO work. SPM operates that financial control function for SWPPP and erosion control contractors, and the flagship case study shows what it looks like installed. ---
CFOS serves commercial swppp / erosion control subcontractors doing $1M to $12M. Pricing starts at $1,900 per month for companies under $1M and runs to $13,500 per month at the top published band. Onboarding takes 60 days.
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.
Sixty days. We migrate your books back to the start of your last taxable year, set up ControlQore, and build your job costing structure from scratch. Fully operational in two months.
