Before you pick a title, answer one question: are your numbers wrong, or are they right and you still don't know what to do with them? A controller fixes the first problem. A CFO works on the second, and a fractional CFO does that same work for part of the month.
So start from the gap you actually have. Company size and job titles come second.
Key Takeaways
- Controllers make sure the financial statements are accurate, on time and backed by sound internal controls.
- The CFO decides what the business should do with its money: funding, cash planning and the big financial calls.
- Fractional CFO work is the same planning job done for part of the month, which suits a business whose big financial decisions don't fill a full-time week.
- Planning on wrong books wastes the planner's time, so a business with unreliable monthly numbers usually needs bookkeeping or controller work first.
- The federal O*NET job database files controllers with treasurers and lists CFO among chief executive titles, which is why the two roles get blurred.
- Missouri City sits in both Fort Bend County and Harris County, so a business there needs to know which county's appraisal district values its property.
What does each role actually do?
Each role answers a different question.
| Role | Question it answers | What it owns | Where it sits |
|---|---|---|---|
| Bookkeeper | What happened? | Recording transactions and reconciling the accounts | In-house or outsourced |
| Controller | Are the numbers right? | The monthly close, the financial statements and the controls | In-house or outsourced |
| Full-time CFO | What should we do next? | Budgets, cash planning, funding and big financial decisions | An employee on the leadership team |
| Fractional CFO | What should we do next? | The same planning work, for an agreed part of the month | An outside adviser |
What does a controller do?
A controller makes sure the numbers are right and that the process producing them can be trusted. In the Labor Department's O*NET database, the tasks listed for treasurers and controllers include preparing or directing preparation of financial statements, business activity reports, forecasts, annual budgets and reports required by regulators. They also include developing internal control policies for areas like budget administration, cash and credit management, and accounting.
That list includes forecasts and budgets, so the line between controller and CFO is partly one of emphasis. In a small business, the controller's first job is accuracy: running the monthly close, reviewing the bookkeeper's work, and catching the error before it reaches your tax return or your lender.
You probably need controller-level work if:
- Your monthly reports arrive late, or you don't trust them when they do.
- Your bank balance and your books disagree and nobody can explain why.
- More than one person touches payments and nobody checks the other's work.
- A lender, buyer or investor is about to ask for financial statements.
If you're not sure whether your books are right, start with the three reports that tell you whether your books are right.
What does a CFO do?
A CFO decides what the business should do with its money. O*NET doesn't give CFO its own occupation. It lists Chief Financial Officer as a sample title under chief executives, whose tasks include directing or coordinating an organization's financial or budget activities to fund operations, maximize investments or increase efficiency, and preparing budgets for approval.
That's a forward-looking job, and the emphasis is direction rather than accuracy. The CFO asks whether you can afford the second location, how to fund the equipment, what happens to cash if your biggest customer pays sixty days late, and which lines of the business are actually making money. The controller hands over accurate numbers. The CFO turns them into a plan.
You probably need CFO-level thinking if:
- A decision on the table could sink the business if the math is wrong.
- You're about to borrow, raise money or bring in a partner.
- Sales are growing, cash still feels tight, and nobody can say why.
- Accurate reports arrive every month and you still don't know what they're telling you.
What is a fractional CFO, and how is it different from a full-time one?
A fractional CFO does the same forward-looking work for part of the month, as an outside adviser rather than an employee. The scope is whatever you agree on, for example a regular planning meeting, a cash forecast, a budget, and help with specific decisions as they come up.
The difference from a full-time CFO is how much of that work you actually have. A full-time CFO makes sense when there's a full week of financial decisions every week, a finance team to lead, and outside parties such as investors or lenders who need a dedicated contact. If your big financial calls come a few times a quarter, paying for forty hours a week of CFO time means paying for a lot of time spent waiting for the next decision.
A fractional arrangement has its own tradeoffs, and they're worth saying out loud:
- They're not in the building. Someone else still has to run the day-to-day finance work.
- Their time is limited, so the agenda for each meeting matters.
- They're only as good as the numbers they're given.
That last point is easy to overlook.
Which one should I hire first?
Fix the numbers before you plan with them. If your books aren't reliable month to month, a CFO will spend their time cleaning up rather than planning, and you'll pay CFO rates for controller work. Get the bookkeeping and the monthly close right first, then add forward-looking help.
A practical way to decide:
- Books behind, or you don't trust them: start with bookkeeping cleanup. Our post on when a Houston business needs a CPA vs just a bookkeeper covers that step.
- Current books that nobody reviews, with nobody checking the controls: add controller-level oversight, in-house or outsourced.
- Numbers you trust, plus decisions coming up about growth, funding or cash: bring in a fractional CFO.
- A finance team to lead, investors or lenders who need constant attention, and strategic decisions every week: that's when a full-time CFO starts to make sense.
If you're weighing hiring someone versus outsourcing the day-to-day work, our comparison of an in-house bookkeeper vs an outsourced CPA goes through that choice.

What changes for a Missouri City business?
Mostly nothing about the roles themselves, but one local detail lands on the controller's desk. The Texas Almanac's Missouri City entry lists the city under both Fort Bend County and Harris County, so two addresses in the same city can sit in different counties.
Each of those counties has its own appraisal district, the Fort Bend Central Appraisal District and the Harris Central Appraisal District. The Texas Comptroller's property tax basics page explains that appraisal districts value property as of January 1 each year. So the first thing to know about your business property here is which side of the county line your address falls on.
Keeping that straight is controller-level work: a current list of what the business owns, where it sits and what it cost. If nobody keeps that list today, it belongs on the controller's plate before anyone starts on forward planning. For the rest of what we do for owners in town, see our Missouri City page.
What should I have ready before I talk to a fractional CFO?
Enough to let them see where things stand in the first meeting, without a month of digging.
- Your last twelve months of profit and loss statements and balance sheets.
- Bank and loan statements, and any lines of credit.
- Last year's business tax return.
- The one or two decisions that are keeping you up at night.
The decision list matters most. A fractional CFO engagement works best when it starts with a specific question, like whether to add a location or how to fund a slow season. A general request to look at the numbers gives them nothing to plan around.
