RUN ON CFOS, THE CONSTRUCTION FINANCIAL OPERATING SYSTEM.

QUICK ANSWER

CFOS is the financial operating system SPM installs and operates for commercial subcontractors doing $1M–$12M. Not a dashboard. Not bookkeeping software. A six-module operating architecture that identifies the upstream operational failures causing financial instability (underpriced work, labor overruns, billing lag, WIP distortion, stalled change orders, weak collections, PM accountability gaps) and corrects them through the same monthly cadence, every engagement, every trade.

Most subcontractor financial problems have a clear operational cause. The bank account does not reflect what the business earned because a pay app went out late. The job that looked profitable closed at a loss because labor ran over on a phase nobody tracked. The LOC is maxed because three projects mobilized simultaneously and working capital was sized for last year's revenue. CFOS is the system that catches those failures before they compound. We do not wait for data. We know what is broken before we see the first number. The first 60 days are fixing it.

THE SIX MODULES

What CFOS Actually Is

Six modules. Each one fixes a specific layer of the financial structure. SPM runs all six on every engagement, not as separate services, but as one integrated system.

01

Cash Control System

Payroll timing, AR aging, LOC management, cash position. The layer that keeps Friday from becoming a crisis.

CASH CONTROL →
02

Job Profitability System

Per-project job costing aligned to estimates. Cost-to-complete. Labor variance. See which jobs make money while they are open.

JOB PROFITABILITY →
03

Cash Flow Cycle System

Billing velocity, pay app timing, AR follow-up rhythm, and 13-week cash forecasting. Stop the feast-or-famine pattern.

CASH FLOW CYCLE →
04

Working Capital System

Bonding capacity, surety relationships, LOC management, and capital requirements forecasted against your backlog.

WORKING CAPITAL →
05

Trade Benchmarking System

Gross margin, net margin, and overhead rate benchmarks by trade. Know where you should be, and what is holding you back.

TRADE BENCHMARKING →

WHAT CFOS IS NOT

Not a Dashboard. Not a Bookkeeper.

Generic bookkeeping records what happened. A dashboard shows you a number. Neither one tells you why the number is wrong or what to do about it.

CFOS is an embedded financial control function. SPM runs it. You attend one monthly meeting and handle 5–10 hours of financial work a month. Everything else is handled: job costing, bookkeeping, bank reconciliations, AR follow-up, cash forecasting, WIP reporting, and monthly reporting.

The first 60 days are migration and installation. Day 60 is proof. Clean books, job costs aligned to estimates, and a 13-week cash forecast showing what is coming. Not the start of trying. Proof that it is working.

The engagement promise: We do not wait for data. We know what is broken before we see a number. A $4.9M concrete contractor was doing $161K net on $4.9M revenue. In the first week we collected $203K in overdue AR. By year end: $1.1M net profit. First year. Same business. See the case study →

COMMON QUESTIONS

FREQUENTLY ASKED.

CFOS, the Construction Financial Operating System, is the six-module financial control architecture that SPM installs and operates for commercial subcontractors doing $1M to $12M. The six modules are: Cash Control, Job Profitability, Cash Flow Cycle, Working Capital, Trade Benchmarking, and Operating Model. SPM runs all six on every engagement as one integrated system, not as separate services.
Bookkeeping records what happened. A generic CFO reads the report and advises. CFOS identifies the operational breakdown causing the financial problem, billing lag, underpriced overhead, labor variance, stalled change orders, and fixes it. SPM does not advise. We run the function. See the operating model →
CFOS serves commercial subcontractors and GCs in 24 trades: civil, sitework, underground utility, grading, excavation, concrete, masonry, framing, structural steel, waterproofing, EIFS/stucco, concrete flatwork, electrical, SWPPP/erosion control, drywall, insulation, demolition, paving, marine, fiber, telecom, flooring, security systems, and interior. Each trade has its own OS page explaining the specific cash failure patterns for that trade and how CFOS addresses them.
60 days. Books migrated to the start of your last taxable year. ControlQore set up and job costing structure built. Fully operational by day 60, not still figuring things out, actually working.
One monthly meeting. 5 to 10 hours of financial work a month. SPM handles the rest: bookkeeping, job costing, bank recs, AR follow-up, cash forecasting, WIP reporting, and the monthly CEO report. The goal is for you to stop being the financial function and start running the business.
Core Financial starts at $1,900/month for revenue under $1M. Executive Financial starts at $2,900/month. Pricing scales with revenue. No hourly billing. No add-ons. No scope gaps. Full pricing breakdown →
