CFOS MODULE 06 · OPERATING MODEL DEFINITION

THREE PROVIDERS. NOBODY RESPONSIBLE.

QUICK ANSWER

Most subcontractors under $12M have a bookkeeper, a CPA, and a software subscription, and no one whose job is the whole picture. Each provider does their piece correctly and the spaces between them are where the money goes. Operating Model Definition is the CFOS module that sets who owns which number, on which day, so nothing depends on the owner noticing.

The reason adding a provider doesn't fix this is that bookkeeping, controllership, and CFO work answer different questions. A bookkeeper tells you what happened, a controller confirms the record is right today, and a CFO tells you what to do next and pressure tests it before you commit. Hiring a better bookkeeper improves the accuracy of a report nobody is using to make decisions. When each of those three functions has an owner and a date, the monthly close stops being a filing exercise and becomes the reason a decision gets made in week two instead of at year end.

WHERE THE MONEY GOES

WHAT HAPPENS WITHOUT THIS SYSTEM.

01

Every provider is doing their job and the result is still wrong

The bookkeeper records what they're given, the CPA files from what they receive, and the software reports what's entered. None of them is responsible for whether the job cost structure supports a decision or whether the close happened in time to change anything. The owner ends up as the integration layer between three vendors, which is the one role they're least equipped and least available to fill.

02

The close finishes too late to be useful

When books aren't closed and reconciled by the tenth, you carry double entries and unapproved costs that haven't reached the balance sheet, so the profit and loss and the cash position are both wrong. A report that comes out on the 25th describes a month you can no longer influence. The date the close finishes determines whether the numbers are management information or history.

03

Nobody in the field owns a number

When project managers aren't accountable for cost to complete, job financials become an accounting output rather than an operating tool, and the people closest to the work never see the consequences of their estimates. Problems surface at closeout, when leadership can't help. Billion dollar companies have project managers present cost to complete to leadership on a fixed day every month, and the reason is accountability rather than reporting.

WHAT OWNERS BLAME

WHAT OWNERS THINK IS WRONG. WHAT IS CAUSING IT.

What owners think: Owners conclude the bookkeeper is the problem and replace them, which is the cheapest available action and the one that seems most likely to help.

What's causing it: Bookkeeping is rarely the constraint, and a second or third bookkeeper produces the same result because the missing function is above bookkeeping. Nobody has defined which number each person owns, when it's due, and who reviews it, so accuracy improves while decision making doesn't. The fix is a cadence with owners and dates attached, and it works with the bookkeeper already in place more often than not.

HOW CFOS CONTROLS IT

WHAT THIS MODULE DELIVERS.

A written cadence assigning every recurring financial task to a person and a date, from weekly cost approval through the monthly CFO meeting
Books closed and bank reconciliations completed by the tenth, so the profit and loss and cash position are both usable
Cost to complete owned by whoever runs the job, presented monthly rather than compiled by accounting
A CEO report covering thirteen months, so the trailing twelve can be averaged and this month compared to the same month last year
A monthly meeting that ends in written decisions with owners and dates, rather than a report review
WHICH TRADES FEEL THIS MOST

WHERE IT HITS HARDEST.

OWNER OPERATED COMPANIES UNDER $3M

The owner is the only integration point

At this size the owner estimates, sells, manages the work, and reconciles the providers, which means the financial function runs at whatever attention is left at the end of the week. This is where the cadence produces the largest change, because it moves work off the owner rather than adding to it. Most of what we install here is a calendar and an owner for each line on it.

COMPANIES WITH A FIRST OFFICE HIRE

A capable person with no defined scope

Somewhere around $3M to $6M a contractor hires an office manager or a bookkeeper and gives them everything financial without defining what they own. The person is usually capable and is being asked to do controllership and CFO work they were never scoped for. Defining the boundary turns a struggling hire into a strong one more often than replacing them does.

COMPANIES WITH PROJECT MANAGERS

Field accountability that has never been asked for

Once there are project managers, the largest available improvement is making them accountable for cost to complete on a fixed day each month. It changes bidding, because the people producing the estimates finally see how they performed. It also surfaces problems while leadership can still help solve them.

WHAT CHANGES WHEN THIS IS FIXED

THE OUTCOME IN PLAIN NUMBERS.

What changes first is the calendar rather than the numbers. Books close by the tenth, cost to complete is presented shortly after, the CEO report follows, and the CFO meeting ends with written decisions, owners, and dates. Nothing in that sequence depends on the owner remembering to ask.

The result Josh built the firm around is an owner spending roughly five hours a month on finance and knowing more about their business than they did spending twenty. We aren't a bookkeeping firm and we aren't a CPA firm, and the whole point of defining the model is that there are no spaces left between the services for money to fall through.

COMMON QUESTIONS

FREQUENTLY ASKED.

A bookkeeper records what happened, which is transactions, coding, and bank reconciliation. A controller makes sure the record is accurate right now, which means the close is complete, costs are approved, and the balance sheet reflects reality. A CFO works forward, forecasting cash, pressure testing decisions before they're made, and setting margin and capacity targets. Most subcontractors have the first, borrow the second from their CPA once a year, and have never had the third.
Owner operated companies under $3M, because the owner is the only integration point between three providers and the financial function runs on whatever attention is left. Companies that have made a first office hire between $3M and $6M, because a capable person is being asked to do controllership and CFO work nobody scoped. Companies with project managers, because field accountability for cost to complete is the largest available improvement and almost never asked for.
A written cadence assigning every recurring financial task to a person and a date, books closed and reconciled by the tenth so the profit and loss and cash position are usable, cost to complete owned by whoever runs the job and presented monthly, a CEO report covering thirteen months so the trailing twelve can be averaged, and a monthly meeting that ends in written decisions with owners and dates rather than a report review.
