What does CFOS replace for a construction subcontractor?

CFOS replaces four things most subcontractors already have but 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 interpretation work alone. CFOS integrates all four into one operating system with no gaps between what the books say and what the CFO advises.

Is CFOS a replacement for a bookkeeper?

CFOS includes bookkeeping — the controller handles the monthly close, bank reconciliations, and record accuracy. But CFOS is an operating system that includes bookkeeping as one layer, not a bookkeeping service. The controller who closes the books is the same person who runs the WIP, reviews job cost, and reports to the CFO. There is no handoff between separate vendors.

Does CFOS replace a CPA?

No. CFOS does not replace tax preparation or compliance work. SPM works alongside your existing CPA. The difference is that you arrive at tax time with 12 months of clean, verified, job-cost-backed financials instead of a shoebox. The CPA's work gets easier and the outcome improves because the books are accurate all year, not reconstructed in March.

What is the difference between CFOS and a fractional CFO service?

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

How long does it take to get CFOS set up?

60 days. Books migrated back to the start of the last taxable year, chart of accounts rebuilt for job costing, ControlQore configured, first monthly cadence running. The 60-day target is a hard commitment, not an estimate.

THE CFOS OPERATING SYSTEM

WHAT CFOS REPLACES IN CONSTRUCTION.

QUICK ANSWER

Most construction subcontractors already have a bookkeeper, a CPA, and a spreadsheet. They still don't know if they're making money on individual jobs. CFOS replaces that setup entirely — not by adding a layer on top of it, but by replacing the structure that produces those blind spots.

Most construction subcontractors already have a bookkeeper, a CPA, and a spreadsheet. They still get surprised at the end of the year. They still make decisions based on bank balance instead of actual financial position. CFOS replaces the setup that produces those outcomes, not by adding a new layer on top of it, but by replacing the structure entirely.

THE EXISTING SETUP AND ITS GAPS

WHAT MOST SUBCONTRACTORS CURRENTLY HAVE.

Before CFOS, the typical financial setup for a $3M–$8M subcontractor looks like this. Each piece does something. None of them talk to each other. And the owner ends up doing the interpretation work that none of them are positioned to do.

WHO

BOOKKEEPER

Records transactions. Reconciles the bank. Produces a P&L at month-end.

THE GAP

Can't interpret what the numbers mean. Can't run WIP. Can't build a cash forecast. Can't tell you if Job 14 is losing money. Not trained to connect bookkeeping output to operational decisions.

CFOS REPLACES WITH

A controller who closes the books, reconciles, runs the WIP, reviews every job's cost-to-complete, and reports to the CFO monthly. Same transaction accuracy, plus the interpretation layer that turns records into decisions.

WHO

CPA / TAX FIRM

Files the tax return. Handles compliance. Answers questions during tax season.

THE GAP

Looks at the business once a year in March. Not reviewing job margins in July. Not flagging the overhead rate problem in October. Not in the room when the owner decides whether to take on a $2M job that will break cash flow.

CFOS REPLACES WITH

Monthly strategic meetings with the CFO. Not tax advice, operating advice. Cash position. Job margins. Overhead rate. The decisions that happen between January and December, not just the ones reviewed in March. CFOS works alongside your CPA, not instead of them.

WHO

SPREADSHEETS

Job cost tracking in Excel. Cash flow projection in a different tab. WIP calculated manually once a quarter.

THE GAP

Numbers nobody fully trusts because they're assembled by hand. WIP that's three months old when decisions are made. Job cost that doesn't match the bookkeeping because they're in different systems.

CFOS REPLACES WITH

ControlQore, a job costing and WIP platform connected to the books. Numbers that reconcile because they come from the same system. WIP run monthly from closed books. Cash forecast built from actual AR aging and billing schedule.

WHO

THE OWNER

Doing the financial interpretation work nobody else is doing.

THE GAP

Getting bookkeeping output, a tax return, and a spreadsheet, then figuring out what it all means alone. Making cash flow decisions based on bank balance. Running the business on intuition because the system doesn't produce actionable output.

CFOS REPLACES WITH

About 5 hours a month. One monthly meeting with the CFO. An action list that comes out of it. The owner runs the business. CFOS runs the financial operating system. Same team, no gaps.

BEFORE AND AFTER

WHAT CHANGES WHEN CFOS IS IN PLACE.

BEFORE

P&L shows profitable. Bank account is empty. Owner doesn't know why.

CFOS

CEO Report shows cash flow, job margins, AR aging, and working capital in one view. The gap between P&L profit and bank balance has an explanation every month.

BEFORE

Job 14 closes $80K worse than estimated. Nobody saw it coming.

CFOS

Job 14 was flagged in month two when cost burn was trending 12 points above estimate. The PM was in the room. The problem was addressed while there was still time to act.

BEFORE

Made $4.9M last year. Netted $161K. Nobody knows where the rest went.

CFOS

Overhead rate was 28% instead of the 10% in the estimate. Every job was priced 18 points below what it cost to execute. The problem was in the bid structure, not the field. Fixed in the next bid cycle.

BEFORE

MCA loan at 48% APR taken out to cover payroll. Owner doing this alone at 11pm.

CFOS

13-week cash forecast showed the payroll gap eight weeks out. LOC draw planned. MCA never needed. Owner slept through the night.

The concrete sub doing $4.9M: had a bookkeeper, filed taxes on time, and tracked jobs in a spreadsheet. Netted $161K on $4.9M of revenue — 3.3%. After CFOS identified the overhead rate problem and rebuilt the bid structure, net profit went to $1.1M on $5.2M of revenue the following year. The work didn't change. The financial system did.
