CONSTRUCTION CONTROLLERSHIP FOR SUBCONTRACTORS.

Controller-level financial oversight for commercial subcontractors doing $1M to $12M. The layer between the bookkeeper and the CFO. Month-end close, WIP schedule, financial statement review, and job cost variance — done monthly, not just at year-end. Part of CFOS — the Construction Financial Operating System.

Construction controllership services for commercial subcontractors doing $1M to $12M. SPM (Sulphur Prairie Management), operating as The Construction CFO, provides controller-level financial oversight including month-end close oversight, WIP schedule preparation and review, financial statement review, job cost variance review, and internal controls. Construction controllership requires trade-specific knowledge of WIP overbilling and underbilling mechanics, percentage-of-completion revenue recognition, and retainage accounting — not general controller skills. Powered by CFOS — the Construction Financial Operating System. Included in Executive Financial tier starting at $2,900/month. 60-day onboarding. No payroll. No tax preparation.

THE FINANCIAL STACK

WHERE CONTROLLERSHIP FITS.

Most subcontractors have a bookkeeper. Some have a CFO or advisor. Almost none have the layer in between — and that missing layer is usually where the numbers fall apart.

LAYER 1
Bookkeeper
Records transactions. Categorizes expenses. Reconciles bank accounts. Does not own the meaning of the numbers.
LAYER 2 — THIS SERVICE
Controller
Owns the close. Builds the WIP schedule. Reviews job cost variances. Ensures financial statements are accurate and construction-specific.
LAYER 3
CFO
Uses the clean numbers to make decisions — cash flow forecasting, working capital management, strategic oversight.

A CFO without a controller is building strategy on unverified numbers. A bookkeeper without a controller means nobody owns whether those numbers are right. Construction controllership is the function that makes the other two work.

When a concrete contractor's overhead rate was wrong by 11 percentage points for two years, it wasn't a bookkeeping problem — the transactions were categorized correctly. It was a controllership problem. Nobody was reviewing the cost structure against benchmarks or running the job cost variance that would have caught it.

WHAT CONSTRUCTION CONTROLLERSHIP IS

GENERAL CONTROLLERSHIP VS CONSTRUCTION.

Construction controllership is not general controllership applied to a contractor. The mechanics are different. A general controller who has never managed a WIP schedule will get it wrong — and getting WIP wrong has direct consequences for bonding capacity, bank covenants, and the accuracy of every financial statement the business produces.

GENERAL CONTROLLER
Closes the books and produces a P&L
No WIP schedule — doesn't know what one is
Revenue recognized when invoiced, not by percentage of completion
Retainage treated as a simple receivable
No job cost variance review — just overall margins
Cannot explain overbilling vs underbilling to a banker
Financial statements accurate but not construction-meaningful
SPM CONSTRUCTION CONTROLLER
Owns the month-end close and WIP schedule preparation
WIP schedule built monthly — overbilling and underbilling tracked
Revenue recognized on percentage-of-completion basis
Retainage tracked separately, aged, and tied to completion milestones
Job cost variance reviewed against estimate — by phase, by job
Explains WIP to bankers, bonding agents, and CPAs in their language
Financial statements construction-accurate and audit-ready
WHY WIP MATTERS

WIP IS WHERE SUBCONTRACTORS GET MISREAD.

The WIP schedule is the most important financial document a subcontractor produces — and the most commonly wrong. Banks require it. Bonding companies require it. CPAs need it for accurate financial statements. When it's wrong, every number downstream is wrong.

OVERBILLING
You've billed more than you've earned based on percentage of completion. Looks like cash. Is actually a liability. If overbilling isn't tracked, your balance sheet overstates revenue and your bonding capacity is inflated by a number that doesn't exist.
UNDERBILLING
You've earned more than you've billed. Work is done, money isn't collected, and the asset isn't showing on your balance sheet. Underbilling is common on percentage-complete jobs with slow billing cadence — and it compounds the cash problem that Cash Control is designed to fix.
% OF COMPLETION
Revenue recognized proportional to how far along a job is — not when you invoice. Required for accurate WIP reporting. A general bookkeeper recognizes revenue when invoiced. A construction controller recognizes it when earned. The difference can be hundreds of thousands of dollars on a single job.
RETAINAGE
The percentage held back by the GC until substantial completion. Tracked separately from regular AR. Has its own aging profile. Retainage that isn't being actively managed — collected after completion, escalated when withheld past contract terms — sits on the balance sheet and quietly drains working capital.
WHAT'S INCLUDED

WHAT SPM CONTROLLERSHIP DELIVERS.

Month-end close oversight — books closed, reviewed, and finalized monthly
WIP schedule preparation — built monthly from job cost data, overbilling and underbilling tracked
WIP schedule review — variances flagged, overbilling and underbilling explained to owner
Financial statement review — P&L, balance sheet, and cash flow statement reviewed for construction accuracy
Job cost variance review — actual vs estimate by job and by phase, monthly
Retainage tracking — aged separately, completion milestones monitored
Internal controls — process checks to prevent misclassification and catch errors before they compound
Liaison to CPA and banker — speaks construction accounting in their language on your behalf

Not included:

Payroll processing
Tax preparation or filing
Audit services
Day-to-day bookkeeping (included in Core Financial — see Construction Bookkeeping Services)

Controllership is included in the Executive Financial tier. It runs on top of the bookkeeping foundation — you don't need to manage both separately. SPM owns the full stack.

WHEN YOU NEED IT

THREE SIGNS YOU NEED A CONTROLLER.

01

Your Bank or Bonding Company Asked for a WIP Schedule

And you didn't have one — or the one you produced wasn't trusted. Bankers and bonding agents who work with contractors know what a correct WIP looks like. A wrong one signals that the financial oversight of the business is thin. A missing one stops a line of credit review or bonding application cold.

02

Your CPA Has to Clean Up the Books Every Year at Tax Time

If your accountant spends significant time reconstructing the year before they can file — reclassifying transactions, correcting revenue recognition, building the WIP from scratch — controllership is the function that should have been running all year. Tax prep should be a formality, not a reconstruction project.

03

You Don't Know If Your Financial Statements Are Right

If you look at your P&L and genuinely aren't sure whether the numbers are accurate — because nobody has been reviewing them against job cost reality — that's a controllership gap. The Job Profitability module can't run on unreviewed numbers. Controllership is what makes the numbers trustworthy.

POWERED BY CFOS

THE SYSTEM BEHIND THE SERVICE.

Construction controllership at SPM runs on CFOS — the Construction Financial Operating System. CFOS is a six-module financial control architecture built specifically for commercial subcontractors.

Controllership is one entry point into that system. It connects directly to two CFOS modules: Job Profitability — which requires clean, reviewed job cost data to produce per-job variance reports — and Benchmarking — which requires accurate financial statements to compare overhead rates and margins against trade norms.

When a $4.9M concrete contractor discovered their overhead rate was wrong by 11 points, it was a controllership failure. The bookkeeping was accurate. Nobody had reviewed the cost structure. Read the concrete case study to see what the fix looked like →

WHO IT'S FOR

FIT. AND NOT FIT.

PERFECT FIT

Commercial subcontractors doing $3M to $8M in civil, concrete, electrical, SWPPP, sitework, underground utility, grading, masonry, and adjacent trades. Bonding capacity is a priority. Bank covenants require reviewed financials. CPA is doing too much cleanup at year-end. Nobody is producing a WIP schedule. Job cost variances aren't reviewed until the job is over.

GOOD FIT

$2M–$3M preparing for their first bonding program or LOC. $8M–$12M scaling fast and financial controls haven't kept up with the volume. Any subcontractor whose bank or bonding agent has questioned the accuracy or completeness of their financial statements.

NOT A FIT

Residential contractors. Under $1M revenue. Mechanical, plumbing, HVAC, glazing, roofing, or solar. If you have no bookkeeping at all — start with Construction Bookkeeping Services first. Controllership requires a working bookkeeping foundation to run on.

COMMON QUESTIONS

FREQUENTLY ASKED.

A bookkeeper records and categorizes transactions. A controller owns what those transactions mean — producing the WIP schedule, reviewing job cost variances against estimates, ensuring revenue is recognized correctly on a percentage-of-completion basis, and making sure the financial statements actually reflect the construction reality of the business. The bookkeeper tells you what happened. The controller tells you whether the numbers are right.
WIP — Work in Progress — is the financial schedule that tracks the relationship between what you've billed and what you've earned on every active job. When you've billed more than earned, that's overbilling — a liability, not revenue. When you've earned more than billed, that's underbilling — an asset sitting off your balance sheet. Banks and bonding companies require WIP to evaluate your financial health because the P&L alone doesn't tell them the construction story. A wrong WIP overstates or understates your position. SPM builds and reviews the WIP schedule monthly.
Controllership is included in the Executive Financial tier and runs alongside the bookkeeping foundation. It is not offered as a standalone service without bookkeeping — controllership requires clean, job-costed books to review. If you have existing bookkeeping that is already structured correctly for construction job costing, that can be discussed on an engagement call. See the full service comparison →
Construction controllership requires specific knowledge of WIP schedule mechanics, percentage-of-completion revenue recognition, retainage accounting, job cost code structure, and the way bonding companies and banks read contractor financials. A general controller who has managed retail or professional services businesses will not have these skills — and learning them on your engagement costs you time and accuracy. SPM controllers come with this knowledge built in because every engagement is construction-only.
60 days. SPM migrates your books to the start of your last taxable year, builds the job cost structure in ControlQore, and produces the first WIP schedule within the onboarding window. By day 60 the monthly close process is running, the WIP is live, and job cost variance reports are producing actionable numbers. Not a 6-month ramp-up — a 60-day operational launch.
