THE OPERATING MODEL

WHAT CFOS REPLACES IN CONSTRUCTION.

QUICK ANSWER

Most construction subcontractors already have a bookkeeper, a CPA, and a spreadsheet, and they still can't say whether they made money on an individual job. CFOS replaces that setup rather than adding a layer on top of it. Each of those three pieces does something useful, none of them talk to each other, and the owner ends up doing the interpreting that none of them are positioned to do.

Before CFOS, the financial setup for a $3M to $8M subcontractor is three vendors and one tired owner. The bookkeeper records what happened, the CPA files taxes in March, the spreadsheet holds numbers nobody fully trusts, and the owner decides off the bank balance. CFOS replaces the structure that produces those outcomes. A controller closes the books and produces the WIP, a CFO works the numbers with you every month, and ControlQore holds the job cost and WIP so it reconciles to the books. The owner gets about 5 hours a month and an action list.

THE DEFINITION

WHAT IT MEANS.

CFOS is a financial operating system for construction subcontractors that replaces the bookkeeper, CPA, and spreadsheet setup with one structure covering bookkeeping, controllership, and CFO advisory.

Each piece of the old setup does something. None of them talk to each other. The owner ends up as the integration layer between three vendors who have never spoken, which is the most expensive job in the company and the one nobody was hired for.

THE SETUP BEFORE CFOS

FOUR BLIND SPOTS.

01

The bookkeeper can't read the numbers forward

A bookkeeper codes transactions and reconciles accounts accurately. They can't produce WIP, build a cash forecast, or tell you whether Job 14 is losing money. That describes the role rather than the person, and it leaves the interpreting to whoever is left holding the file.

02

The CPA looks at the business once a year

A tax firm reviews the business in March and files the return. Nobody is reviewing job margins in July or flagging the overhead rate problem in October. Nobody is in the room when you decide whether to take a $2M job that will break cash flow.

03

The spreadsheets don't reconcile

Numbers stitched together manually are numbers nobody fully trusts. The WIP is three months old by the time a decision gets made off it. Job cost doesn't tie to the bookkeeping because the two live in different systems, so every meeting starts by arguing about which file is right.

04

The owner is doing the interpreting alone

You get bookkeeping output, a tax return, and a spreadsheet, then work out what it all means by yourself. Cash flow decisions get made off the bank balance because that's the one figure you trust. The business operates on instinct, because the setup doesn't produce anything you can act on.

THE MATH

WHAT IT LOOKS LIKE IN DOLLARS.

The concrete sub doing $4.9M

A concrete sub had a bookkeeper, filed taxes on time, and tracked jobs in a spreadsheet. The business netted $161K on $4.9M of revenue, or 3.3 percent, and nobody could say where the rest went. Overhead was 28 percent against the 10 percent used in the estimates, so every job was priced 18 points below what it cost to execute. After the bid structure was rebuilt, net profit went to $1.1M on $5.2M of revenue the following year.

The job nobody caught in time

One job closed $80K worse than estimated and nobody saw it coming. Under CFOS that job gets flagged in month two, when cost is 12 points above estimate and the PM is in the room. The problem gets worked while there's still job left to fix it.

The 48 percent MCA

An owner took an MCA loan at 48 percent APR to cover payroll, working the math out alone at 11pm. A 13 week cash forecast reports that payroll shortfall eight weeks ahead of it. The line of credit draw gets planned, the MCA never happens, and nobody is doing math at 11pm.

WHAT CFOS PUTS IN ITS PLACE

THE FOUR REPLACEMENTS.

A controller instead of a bookkeeper

A controller closes the books, reconciles the accounts, produces the WIP, reviews cost to complete on every job, and reports to the CFO monthly. You keep the same transaction accuracy and get the interpreting layer that turns records into decisions. It's one team, so nothing gets tossed between vendors.

A monthly CFO meeting instead of a March review

Monthly strategic meetings on cash position, job margins, and the overhead rate. Not tax advice, operating advice, covering the decisions you make between January and December. CFOS works alongside your CPA rather than instead of them.

ControlQore instead of spreadsheets

A job costing and WIP platform connected to the books, so the numbers reconcile because they come out of the same system. WIP is produced monthly from closed books. The cash forecast gets built from the AR aging and the billing schedule instead of somebody's memory of what's coming.

About 5 hours a month instead of the owner doing it alone

One monthly meeting with the CFO and an action list that comes out of it. You manage the business and CFOS operates the financial operating system. Same team, no scope gaps.

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. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

COMMON QUESTIONS

FREQUENTLY ASKED.

CFOS replaces four things most subcontractors already have that aren't working together: a bookkeeper who records transactions but can't interpret them, a CPA who files taxes but isn't advising between filings, spreadsheets that produce numbers nobody fully trusts, and the owner doing the interpreting alone. CFOS pulls all four into one operating system with no scope gaps between what the books say and what the CFO advises.

CFOS includes bookkeeping, because the controller handles the monthly close, the bank reconciliations, and record accuracy. But CFOS is an operating system, and bookkeeping is one layer inside it. The controller who closes the books is the same person who produces the WIP, reviews job cost, and reports to the CFO, so nothing gets tossed between separate vendors.

Most fractional CFO services give strategic advice without touching the books. CFOS is a complete financial operating system covering bookkeeping, controllership, and CFO advisory in one structure, built for construction subcontractors. The CFO and the controller are on the same team looking at the same system, so there's no daylight between what the books say and what the CFO advises.

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, set up ControlQore, and build your job costing structure from scratch. Fully operational in two months.
