A good CFO is a finance leader you can trust with the truth about your business, who is skilled enough to do something useful with it. The technical side is the entry fee: accurate numbers, a forecast that holds, cash under control, reporting you can rely on. What makes a CFO good rather than merely competent sits on top of that. Candor when the news is bad. Fluency in how your particular business makes money. The habit of turning a report into a decision. The instinct to fix the system instead of blaming the person. And a plain ethical spine, because the CFO is the one person in the company whose job includes saying no to the CEO and still being welcome in the room the next morning.
I have spent more than twenty years in the CFO chair, most of it in media, advertising and entertainment, and along the way I have hired CFOs, managed them, replaced them, and occasionally been the CFO in question. What follows is the list I wish someone had handed me at 25, when I had the title and not yet the judgment.
Seven things that make a good CFO
None of these are about spreadsheets. Spreadsheet competence is assumed. These are the traits that decide whether the person in the seat makes the company better or just keeps score.
1. They tell you the truth early
The most valuable thing a CFO does is deliver bad news while there is still time to act on it. Cash is going to be tight in eleven weeks. That client has been losing money for two quarters. The forecast you showed the board was optimistic, and here is why. A good CFO says these things in the first meeting they are true, not the last meeting they can be hidden. If your CFO has never told you something you did not want to hear, you do not have a CFO. You have an accountant with a better title.
2. They understand how your business actually makes money
Every industry has its own economics, and a CFO who has not run yours will spend a quarter learning them on your payroll. In an agency that means knowing that gross billings are not revenue, that pass-through media and production inflate the top line and say nothing about health, that margin lives at the client and project level rather than in the aggregate, and that utilization against capacity is the number that decides whether you make money this year. A good CFO asks about these in the first conversation. A generalist asks for the trial balance.
3. They spend more time on the next twelve months than the last one
Reporting what happened is the controller’s job, and it matters. But the CFO’s value is in what has not happened yet: the thirteen-week cash view, the forecast that ties revenue, headcount and capacity together, the model that tells you what a new office or a lost client does to the business before you find out the hard way. A CFO who spends most of the month producing the monthly pack is doing a senior person’s hours on a junior person’s work.
4. They end every report with a decision
Numbers are a means. A good CFO closes the loop: here is what the P&L says, here is what it means, here is what I would do. Which clients to grow, which to reprice or exit, when to hire and when to wait. A pack that nobody acts on is a cost, not a control, and a CFO who hands you the data and leaves the interpretation to you has done half the job.
5. They fix the process, not the person
When something goes wrong, an adequate CFO finds out who did it. A good one finds out why the system let it happen. W. Edwards Deming put the share of outcomes that come from the system rather than the individual at better than 94 percent, and my experience in agency finance suggests he was being conservative. A CFO who blames people loses the people and keeps the problem. One who redesigns the process keeps both the people and the improvement. This is the trait that scales, because it is the one that makes the whole team better rather than just the CFO. I have written about the mechanics of that diagnosis in Fix the Process, Not the Person.
6. They treat people as the point, not the cost line
Payroll is the largest expense in every agency and the easiest place to look when margins slip. A good CFO resists the reflex. They understand that a utilization report is a capacity tool rather than a surveillance tool, that the cheapest hire is rarely the best one, and that a culture where people are afraid of the finance function is a culture where the finance function gets bad data. The aim of the numbers is that everyone connected to the business gains over the long term. Profit is the evidence, not the aim.
7. They are good
This is the one that never appears in a job description and decides everything. A CFO has more unsupervised influence over a company than anyone except the CEO. They see every number, every contract, every salary. A good CFO uses that position to protect the company, its people and its clients, including from the founder’s worse instincts when necessary. They do not take a stake in the outcomes they are advising on; someone advising you on whether to sell should not have a stake in you selling. They do not shade a number to make a quarter look better. They do not hoard information to make themselves indispensable. My mentor put it in a single sentence that became the name of this firm: the hallmark of a great CFO is to be good.
What makes a great CFO, not just a good one
The gap between good and great is not technical. Most good CFOs and most great CFOs can build the same model. The difference is what they do with influence.
A good CFO runs finance well. A great one uses the finance seat to make the whole organization better: the culture, the way decisions get made, how people are treated when something goes wrong, whether the truth travels upward. They think in systems rather than departments, because a company is not the sum of its functions but the interaction between them. And they are a builder as much as a guardian, in the room for growth and not only for control.
I learned that distinction from David Paine at PainePR, where I worked early in my career. David had built the agency on a service manifesto arguing that quality is a systems problem rather than a talent problem, and he ran the business as a service to the people and clients it existed to support. Watching a company led that way, with finance in service of it rather than in judgment of it, reshaped how I think about the job. The longer version is in our story, and the manifesto itself is here.
What a good CFO looks like in an agency
The traits above are universal. How they show up depends on the business, and agencies are unusual enough that it is worth being specific.
They separate revenue from billings on day one
An advertising agency placing media can show $20M in billings and $6M in net revenue. A good agency CFO rebuilds every analysis around the net figure and refuses to let pass-throughs flatter the story, because every ratio that matters, from margin to finance cost to what the business is worth, is wrong until they do.
They price the retainer against the work actually delivered
Retainers drift. Scope grows, the fee does not, and eighteen months later a flagship account at a PR firm or digital shop is being served at a loss by the most senior people in the building. A good CFO tracks fee against hours by client and raises the conversation before renewal, not after.
They read utilization as capacity, not productivity
The question is not whether people are busy. It is whether the shop has the right people at the right cost against the revenue it can realistically win. That is a planning number, and a good CFO uses it to plan hiring rather than to police timesheets.
They know the business is people
In a creative agency, the product walks out the door every night. A good CFO builds the finance function so those people can do their best work, and treats finance as service to them rather than oversight of them.
This is also why the seat should not be a solo act. The CFO owns the judgment and the relationship. A controller and analysts behind them own the close and the analysis, so the senior time goes where it is worth the most. That is how our fractional CFO engagements are structured, and it is the shape I would look for regardless of who you hire.
How to tell if a CFO is good before you hire one
Résumés show technical range. Traits show up under questioning. These five questions expose them quickly, whether you are hiring full time or fractional.
“Tell me about a time you told a CEO something they did not want to hear. What happened next?”
You are listening for specifics, and for what they did after the conversation went badly. A vague answer means it has not happened, which means they have not been doing the job.
“What would you look at first in a business like mine?”
In an agency the answer should reach net revenue after pass-throughs, client-level margin and utilization within a minute. If it starts with the chart of accounts, they have not sat in an agency finance chair.
“Walk me through a forecast you got wrong.”
Every CFO who has forecast anything has been wrong. A good one can tell you why, what they changed, and what they watch for now. A CFO who has never been wrong has never been checked.
“When something goes wrong in accounting, what do you do first?”
Listen for whether the answer is about a person or a process. The good ones go to the process without being prompted.
“Who does the work when the analysis takes forty hours?”
A CFO with no team does forty senior hours of junior work and bills you for all of them. The honest answer describes a bench, or a credible plan to build one.
Signs your CFO is not a good one
These are the patterns I have seen most often, in my own hires and in the agencies that call us after a CFO relationship has quietly failed.
Surprises at month end
A good CFO’s month-end contains no news. The news was delivered weeks earlier, when something could still be done about it.
Reports without recommendations
If the pack arrives and the decision is left to you, you are paying CFO rates for a reporting service.
A title that outgrew the work
Plenty of bookkeepers have quietly added CFO to the business card. The test is simple: are they forecasting, pricing and sitting in the strategic conversations, or closing the books? What a fractional CFO actually does is a useful checklist.
Information held close
A CFO who is the only person who understands the model, the bank relationship or the billing has built their job security into your risk profile.
Metrics that improved while the business did not
Utilization went up and profit did not. DSO came down and the client left. When the number gets managed instead of the thing it measures, someone is optimizing the report. There is more on why that happens in What the Numbers Can’t Tell You.
Never says “I don’t know”
Finance is full of uncertainty and a good CFO is comfortable naming it. One who always has a confident answer is either guessing or hiding something, and neither is what you are paying for.
The standard we hold ourselves to
The Good CFO is named for exactly this idea, so it is fair to ask what we do about it.
We wrote the principles down in the manifesto: excellence in both craft and character, responsible use of data including an honest view of its limits, people over spreadsheets, and systems thinking. We turned them into a way of working, The Good CFO Method, which runs every engagement on Deming’s Plan-Do-Study-Act cycle across five pillars: Clarity, Systems, People, Execution and Evolution. And we built the firm as a team rather than a person, because a CFO who is also running the close cannot do the job this article describes. Every engagement pairs a CFO Partner with a controller and analysts, and the partners all came up inside agencies.
None of that is a claim to have finished. It is a standard, and the useful thing about a written standard is that clients can hold you to it.
What makes a good CFO: FAQ
What makes a good CFO?
A good CFO is a finance leader you can trust with the truth about your business, who is skilled enough to do something useful with it. Beyond the technical baseline of accurate numbers, a reliable forecast and cash under control, the traits that matter are candor when the news is bad, fluency in how your particular business makes money, a forward-looking focus, the habit of turning every report into a decision, the instinct to fix the process rather than blame the person, respect for people as the point of the business rather than a cost line, and plain integrity.
What makes a great CFO, not just a good one?
The gap is not technical. A good CFO runs finance well. A great CFO uses the influence of the finance seat to make the whole organization better: how decisions get made, how people are treated when something goes wrong, whether the culture tells the truth. They think in systems rather than departments and act as a builder as much as a guardian. The shortest version we know is the line the firm is named for: the hallmark of a great CFO is to be good.
What are the most important skills for a CFO?
Forecasting and modeling, cash management, pricing and profitability analysis, and clear communication of what the numbers mean. Those are the craft. The skills that decide whether someone is good in the seat are harder to list on a résumé: delivering bad news early, understanding the economics of the specific business, and designing systems so that good people produce good results without heroics.
What is the difference between a good CFO and a good controller?
A controller makes the numbers right and closes the books on time. A CFO decides what to do about them and looks forward: strategy, forecasting, capital, pricing, the decisions that shape the business. They are different disciplines, not levels of one job. A good CFO who is also running the monthly close is doing senior hours on junior work, which is why the seat works best with a controller and analysts behind it.
How do you know if your CFO is good?
Ask yourself three things. Have they told you something you did not want to hear, early enough to act on it? Does every report they give you end in a recommendation? When something goes wrong, do they go looking for the person or the process? A CFO who fails all three is keeping score, not leading finance. Month-end surprises, reports without recommendations, and information held close are the most common warning signs.
What makes a good CFO for a marketing or creative agency?
Agency experience, specifically. A good agency CFO separates net revenue from gross billings on day one, measures margin at the client and project level, reads utilization as a capacity-planning number rather than a productivity score, and prices retainers against the work actually delivered. They also understand that in an agency the product is people, so the finance function is built to serve them rather than police them.
The bottom line
What makes a good CFO is not the numbers. It is what the person does with them: telling you the truth early, understanding the business well enough for the truth to be useful, turning it into decisions, fixing systems instead of blaming people, and holding the seat with integrity. Hire for those traits, test for them directly, and the technical competence almost always comes with them. The reverse is not true.
