Notes · Controller
When does a growing business need a controller?
Short version: You need a controller when the person who records the transactions can no longer explain them. A bookkeeper records what happened. A controller owns whether the record is right, on time, and usable by the people who rely on it. Most companies feel this gap long before a full-time hire makes sense, which is why a fractional controller is usually the right first step.
Owners usually ask how big the company has to be before it needs a controller. Size is the wrong test. Complexity is the right one: how many entities, properties, or jobs the books have to track, how many people touch money, and how many outsiders (lenders, investors, a surety, a partner) depend on the numbers being right.
The bookkeeper line and the controller line
A bookkeeper enters bills, deposits, and payroll, and reconciles accounts when time allows. That is real work and it has to be done well. A controller sits one level up. The controller sets the close calendar, decides how transactions are coded, reviews the reconciliations, builds the reports, and answers for the result.
When nobody holds that seat, the bookkeeper ends up making judgment calls they were never hired to make, and the owner finds out when a lender asks a question.
Seven signs you have hit the controller gap
- The month does not close on a schedule. Some months take ten days, some take thirty, and some never close.
- Your CPA spends the first weeks of the year fixing the books instead of preparing the return.
- Bank, credit card, and loan accounts are reconciled "when there is time."
- Profit by property or by job is a spreadsheet project, not a report.
- Balances between your own entities do not agree, and nobody owns the difference.
- A lender, investor, or surety asks for a package and it takes days to assemble.
- You are the only person who can tell whether a number looks right.
Two or three of these is normal for a growing company. Five or more means the books are costing you decisions.
Controller gap or CFO gap?
They are different problems. If the question is "are the numbers right," you need a controller. If the question is "what do we do with them" (how much cash we will have in thirteen weeks, whether to buy, refinance, or hold, what a lender will say), you need a CFO.
Most businesses need the controller work first, because a CFO working from unreliable books is guessing with better vocabulary.
Full-time or fractional?
| Full-time hire | Fractional controller | |
|---|---|---|
| Cost structure | Salary, benefits, and a seat to fill | A scoped monthly engagement |
| Coverage | Every day | Planned on a calendar: close, review, reporting |
| Best fit | Enough daily volume and decisions to keep one person fully busy | Complex books that do not yet fill a full-time role |
| Main risk | Paying for capacity you do not use yet | Needing an answer on a day that is not on the calendar |
The usual path is fractional first, full-time once the volume justifies it. By then the close calendar, the chart of accounts, and the reports already exist, so the new hire inherits a system instead of building one.
What a controller actually fixes
- A close calendar that runs the same way every month
- Reconciliations that are reviewed, not just prepared
- A chart of accounts that matches how you run the business: by property, job, or entity
- One-page management reports on a fixed day
- Controls over who can approve, pay, and change records
- Books your CPA can use without a cleanup

Common questions
Do I need a controller or a CFO?
If your books are late or unreliable, start with a controller. If the books are sound and the questions are about cash, capital, and strategy, start with a CFO. Many engagements begin with both at a light level and shift the weight over time.
Can my bookkeeper grow into the controller role?
Sometimes. It works when the bookkeeper has the judgment and the appetite, and someone senior reviews the work while they grow into it. It fails when the owner expects one person to both record the transactions and oversee the record, because nobody is checking the checker.
Is a fractional controller the same as an outsourced accounting firm?
No. An outsourced firm usually takes over the transaction work. A fractional controller owns the close, the controls, and the reporting, and works with whoever does the data entry, whether that is an in-house bookkeeper or an outside provider.
Will you replace my CPA?
No. I am not a CPA and I do not prepare tax returns. I work alongside your CPA so the books they receive are clean, reconciled, and match what you ran the company on.
