A fractional controller is an experienced financial controller who works for your business part-time, on an ongoing basis, instead of being hired full-time. They own the accuracy of your financials: the monthly close, the balance-sheet reconciliations, AP and AR discipline, and the internal controls that make your reporting mean something. You get the seat you actually consume rather than the whole salary.
It is the least glamorous title in finance and the one most agencies need first. Nobody has ever been excited about a reconciliation. But every strategic conversation about pricing, capacity, or a possible sale runs on the numbers this person produces, and if those numbers are soft, everything built on top of them is guesswork in a nicer font.
What a fractional controller actually owns
The job is integrity of the record. Not more reports, and not opinions about strategy. Four things sit squarely with the controller:
The monthly close, on a calendar
A defined sequence with owners and dates, landing inside five to ten business days. Fast enough that the numbers still inform a decision rather than confirming one you already made.
Reconciliations that tie
Cash, receivables, payables, prepaid, accrued, deferred. If the balance sheet does not reconcile, the P&L is a story rather than a statement, and no amount of dashboard styling fixes that.
AP, AR, and the aging nobody is watching
Somebody has to notice the receivable that quietly slipped past sixty days, and chase it while the client still remembers the work. That noticing is the job.
Controls and consistency
Coding reviewed before a bad habit hardens into a bad trend, so the same line item means the same thing in March as it did in January. Consistency is what makes a trend readable.
Bookkeeper, controller, CFO: three jobs, not three pay grades
This is the distinction that costs agencies the most money, usually by hiring one and expecting another.
Bookkeeper
Records what happened. Enters the transactions, codes them, keeps the ledger current. Essential, and largely execution.
Controller
Decides whether what was recorded is right, and designs the system that keeps it right. Close calendar, chart of accounts, reconciliations, controls, GAAP-aligned statements. Backward-looking and inward-facing, by design.
CFO
Decides what to do about it. Forecasting, pricing and utilization strategy, capital, acquisitions, the conversation with your bank. Forward-looking and outward-facing.
Promoting a good bookkeeper into a controller seat rarely works, and not because they lack ability. The roles ask for different instincts: one is disciplined execution, the other is designing a system and then being willing to tell you it is broken. Similarly, a fractional CFO hired on top of unreliable books will spend the first quarter doing controller work at CFO rates. Get the record clean, then buy the strategy layer.
When an agency has outgrown a bookkeeper
There is no revenue line where this switches on, but the symptoms are boringly consistent. Any two of these and you are late:
The close has become a season
You are talking about July results in the back half of August. By then the number is history, not information.
Somebody else is reading your statements
A lender, a board, an insurer, a buyer. The moment your reporting leaves the building, accuracy stops being an internal convenience.
You cannot say what a client earned
Not roughly. Precisely, for the top five. If the answer requires a spreadsheet built from scratch each time, the chart of accounts is fighting you.
The process lives in one person's head
The close works because Dana knows the order to do things in. That is not a process, it is a dependency, and it takes a holiday in August.
Growth made the books worse
New entity, new service line, first retainer of real size. Complexity arrives faster than the accounting function does, every time.
Why an agency controller is a different animal
A generalist controller can close a month. What takes them a quarter to learn is how an agency actually earns, and agency accounting has four traps a generalist walks into on schedule.
Pass-through media booked as revenue
Client money moving through you to a platform is not your revenue. Book it gross and your top line looks impressive while your margin looks broken, which is a strange way to lose an argument with a bank.
Work in progress nobody tracks
Hours delivered and not yet billed are earned fees. Untracked, they turn into write-offs that show up as a mysteriously bad month with no single cause.
Retainers recognized on the invoice date
Recognize the fee when you invoice rather than as you deliver and every quarter reads the same way: a great first month followed by two that look like a problem.
A chart of accounts built for a widget business
No client dimension, no project dimension, no separation of pass-through. It will close cleanly and tell you almost nothing.
Our controllers arrive knowing where those live, because they have made an agency's books tell the truth before. That is the same reason we organise around creative agencies, advertising agencies, and media companies rather than taking whatever walks through the door.
What a fractional controller costs
A fractional controller typically runs $2,000 to $8,000 a month. A full-time controller costs $110,000 to $180,000 in base salary, call it $150,000 to $230,000 all-in once benefits, payroll taxes, and recruiting are counted.
The arithmetic is not close for a business that needs twenty to sixty hours of controller-level work a month. You would be paying a full salary for a seat you use a quarter of the time, and in our experience still not getting a clean close, because nobody senior is reviewing the work. Four things move the number: transaction volume, entity and revenue complexity, the condition of the books when we arrive, and whether day-to-day bookkeeping is included. Most of ours include it, because an experienced controller does the same clean books faster than a dedicated bookkeeper can.
The full breakdown, including how we scope a cleanup separately from the ongoing close, is on the fractional controller service page.
A clean close is the floor, not the ceiling
Here is the part that gets left out of most explanations of this role. A controller will make your numbers trustworthy. A controller will not tell you what to do with them.
Reconciled books do not price a retainer, model the cost of the hire you are considering, decide which of your top ten clients is quietly subsidising the other nine, or sit across from a lender and defend a covenant. That is CFO work, and it is a different discipline with a different time horizon. Plenty of agencies run happily with a controller and no CFO for years. The ones that get caught out are the ones facing something dated: a raise, a sale, a pricing reset, a covenant test. Those do not wait for you to be ready.
Our own view, and the reason we staff both seats from one firm: the forecast a fractional CFO builds should be fed by the close the controller runs, in the same chart of accounts, on the same calendar. When the two sit in different firms, somebody spends the first week of every quarter reconciling two versions of the truth, and that somebody is usually you. The forward-looking layer on top is FP&A and financial analysis, and it only works if this floor holds.
Fractional controller FAQ
What is a fractional controller?
A fractional controller is an experienced financial controller who works for your business part-time on an ongoing basis rather than as a full-time hire. They own the accuracy of your financials: the monthly close, balance-sheet reconciliations, AP and AR discipline, and the internal controls that make reporting reliable. Most companies bring one in when the books have outgrown a bookkeeper but the workload does not yet justify a six-figure salary.
What is the difference between a fractional controller and a bookkeeper?
A bookkeeper records transactions. A controller owns whether the financials are right. The bookkeeper answers "was this entered?" and the controller answers "does this tie out, and would it survive a lender asking questions?" A controller also designs the close calendar and the chart of accounts, which is design work rather than data entry.
What is the difference between a fractional controller and a fractional CFO?
The controller makes sure the numbers are right. The CFO decides what to do about them. The controller looks backward and inward at the month that just closed. The CFO looks forward and outward at the next four to eight quarters: forecasting, pricing, capital, growth. They are different disciplines, not two rungs of one ladder.
When does an agency need a fractional controller?
When the close is chronically late, the balance sheet does not tie, reporting has started feeding a bank or a board, or nobody can explain what a given client actually earned. For most agencies that lands somewhere past a few million in revenue, or earlier if the business runs multiple entities or heavy pass-through media.
Is a fractional controller the same as an outsourced controller?
In practice the arrangement is the same: a senior controller working a defined portion of your month. The difference people mean is posture. An outsourced controller is usually positioned as a vendor delivering a service. A fractional controller works as a member of your team who happens not to be full-time, inside your systems and your close calendar.
How much does a fractional controller cost?
Typically $2,000 to $8,000 a month, against roughly $150,000 to $230,000 all-in for a full-time controller. The range is driven by transaction volume, entity and revenue complexity, the condition of the books on arrival, and whether day-to-day bookkeeping is included. Our fractional controller service page sets out how we scope and budget it.
The bottom line
A fractional controller buys you the one thing no dashboard can manufacture: numbers you can act on without checking them first. For most agencies it is the correct first senior finance hire, and it is cheaper than the full-time version of the same seat. Just be clear about what you are buying. The controller makes the record true. Deciding what to do about it is the CFO's job, and sooner or later a growing agency needs both.
