What is an outsourced CFO, and what does one actually cost?
A senior finance brain on contract instead of payroll — cash forecasting, margin analysis, lender negotiations and board reporting, for the ten to forty hours a month a growing company actually needs it. Here is the scope, the real retainer numbers, and how to tell whether you need a CFO or a controller.
The model has become ordinary for companies between roughly $1 million and $20 million in revenue. Below that, a good bookkeeper and a tax planner usually cover it. Above it, you generally want someone in-house. This page covers what the role includes, what it costs, and how to tell which side of that line you are on.
What does an outsourced CFO do?
An outsourced CFO owns the forward-looking side of your finances. Your bookkeeper records what happened; your tax preparer files it; the CFO decides what to do about it. In practice the work falls into six recurring pieces.
Cash forecasting
A rolling thirteen-week cash view, updated weekly, showing what clears and what does not. This is the single most valuable thing most owners are missing, and it is usually the first thing built.
Margin and unit economics
Which jobs, products, clients or locations actually make money once labor and overhead are allocated honestly. Most companies discover at least one line of business they have been subsidising.
Reporting that a lender or board will accept
Monthly financials with commentary, variance to budget, and the covenant calculations spelled out — rather than a QuickBooks P&L exported the morning it is due.
Banking and lender relationships
Preparing the package, answering the analyst’s questions, and negotiating terms. Owners routinely leave a quarter point on the table because nobody framed the numbers the way a credit committee reads them.
Financial modeling and scenario work
What happens to cash if you add three trucks, open a second location, or lose your largest customer. Built once, then maintained.
Transaction support
Capital raises, acquisitions, and sale preparation — including cleaning up the books eighteen months before a sale, which is when it has to happen if it is going to matter to the price.
What does an outsourced CFO cost?
Most firms will not publish this. Here are the actual retainer bands Whetzel CPA charges, current for 2026.
| Engagement | What it includes | Monthly |
|---|---|---|
| Core | Monthly close, KPI dashboard, monthly review call | from $4,000 |
| Full | Adds rolling cash forecast and board-standard reporting | from $7,000 |
| Transaction | Adds capital raise, acquisition or sale preparation | from $12,000 |
Nationally, outsourced CFO retainers run roughly $3,000 to $12,000 a month depending on scope, company size and how much cleanup the engagement inherits. Hourly arrangements exist and generally run $150 to $400, but they tend to work badly for this role: the value is in someone thinking about your business continuously, and an hourly meter discourages exactly the calls you should be making.
Two things move a quote more than revenue does. The first is the state of the bookkeeping — if the last twelve months have to be rebuilt before anyone can forecast, that is real work and it is quoted separately. The second is reporting cadence: monthly costs meaningfully less than weekly.
Outsourced CFO vs. fractional CFO vs. virtual CFO vs. part-time CFO
These four terms describe substantially the same arrangement, and the differences are mostly marketing. It matters only because you will see all four while shopping and should not assume they signal different services.
| Term | What it emphasises |
|---|---|
| Outsourced CFO | The function sits outside the company. Usually implies a firm behind the individual, so the work does not stop when one person is on holiday. |
| Fractional CFO | A fraction of a full-time role — the most common term when the arrangement is ongoing and the CFO is effectively part of your leadership team. |
| Virtual CFO | The same job delivered remotely. Since almost all of this work is remote now, the word carries less meaning than it did. |
| Part-time CFO | Sometimes means a W-2 employee working reduced hours rather than a contractor. Worth asking which is meant, because the employment relationship differs. |
What actually distinguishes providers is scope, seniority and whether there is a team behind the name. Ask who does the monthly close, who you call when a wire has to go out today, and what happens if your CFO takes another engagement.
Outsourced CFO vs. hiring a full-time CFO
A full-time CFO in a major metro costs $200,000 to $300,000 all-in once salary, bonus, benefits and payroll taxes are counted — more where equity is expected. A company doing $5 million in revenue generally needs fifteen to forty hours a month of that judgment, not 160.
| Full-time CFO | Outsourced CFO | |
|---|---|---|
| Annual cost | $200,000–$300,000 | $48,000–$144,000 |
| Ramp time | 3–6 months to hire | 2–4 weeks |
| Exit cost | Severance, search, gap | 30 days’ notice |
| Depth on your business | Higher | Lower |
That last row is the honest trade. Someone in the building every day knows things a contractor does not — which customer is unhappy, which foreman pads estimates. An outsourced CFO sees the numbers and the meetings, not the hallway. For most companies under $20 million that gap is worth the $150,000 saved. Above it, usually not.
When you need an outsourced CFO — and when you don’t
The clearest signals that it is time:
- You cannot answer what cash looks like in ninety days without building a spreadsheet
- A lender, investor or franchisor is asking for reporting you do not currently produce
- Revenue is growing and margin is not, and you cannot say precisely why
- You are eighteen to thirty-six months from selling and the books will not survive diligence
- You are personally the constraint on every financial decision in the business
And the cases where you should not hire one yet:
- Your bookkeeping is not current. Forecasting from unreconciled books produces confident nonsense. Fix the foundation first — it is cheaper and it is a prerequisite either way.
- Your problem is tax, not finance. If the real question is entity structure or how to reduce this year’s bill, that is tax planning and it costs a fraction of a CFO retainer.
- You are under about $1 million in revenue. At that size a competent bookkeeper plus quarterly tax planning covers nearly everything a CFO would tell you.
- What you actually need is a controller. See below — this is the most common mismatch.
Do you need a CFO or a controller?
A controller runs the accounting function: close the month, reconcile the accounts, manage the staff, keep the numbers right. A CFO uses those numbers to make decisions about capital, pricing and risk. They are different jobs, and companies routinely hire the second when they needed the first.
The test is whether your numbers are reliable or merely late. If the monthly close takes three weeks and you do not trust the result, you need a controller. If the close is clean on day ten and nobody is doing anything with it, you need a CFO. A controller costs meaningfully less — roughly $1,500 to $3,500 a month outsourced — and hiring one first often makes the CFO engagement shorter and cheaper when it does come.
How an outsourced CFO engagement works
At this firm the sequence is deliberately short. A free thirty-minute call to establish whether the fit is real. Then a diagnostic on the current books and reporting, which is where the actual scope becomes clear. Then an engagement letter with a flat monthly fee — no hourly meter, no surprise invoices — and thirty days’ notice on either side.
The first sixty days are usually the same regardless of company: get the close reliable and on a calendar, build the thirteen-week cash forecast, and put a KPI dashboard in front of the owner that answers the three questions they actually ask. Everything strategic comes after that, because none of it is trustworthy before.

Common questions
How many hours a month does an outsourced CFO work?
Typically ten to forty, depending on scope and company size. A $2 million company on a core retainer is usually near the bottom of that range; a $15 million company preparing for a sale is at the top or beyond it.
Is an outsourced CFO the same as a fractional CFO?
In practice, yes. The terms are used interchangeably by most firms. “Outsourced” slightly more often implies a firm behind the individual; “fractional” slightly more often implies an ongoing seat on your leadership team. Confirm scope rather than relying on the label.
Can an outsourced CFO also do my taxes?
Sometimes, and it is worth asking. Many outsourced CFOs are consultants without a CPA license and cannot sign a return. Where the CFO work sits inside a CPA firm, the forecasting and the tax position get built together, which avoids the common failure where a strategy that looks good on the model creates a tax bill nobody planned for.
What does an outsourced CFO need from me to start?
Access to the accounting file, the last two years of tax returns, current debt agreements with covenant terms, and an hour of your time to explain how the business actually makes money. That is enough to produce a first cash forecast within three weeks.
Do I have to sign a long contract?
You should not have to. Retainers here run month to month with thirty days’ notice. Multi-year CFO commitments generally protect the provider rather than the client.
