Fractional CFO vs Bookkeeper vs CPA.

A bookkeeper records what already happened. A CPA files it with the government once a year. A fractional CFO decides what to do about it before it happens. Three different jobs, three different time horizons. Most owners are paying for the first two and quietly missing the third, and the third is the one that moves the bank balance.

Hiring the wrong one is expensive in a way you never see on an invoice. A bookkeeper cannot tell you whether you can afford the hire. A CPA will not warn you about the cash gap in week seven. If you have ever had clean books, a filed return, and still been blindsided by your own numbers, this is why. You had two of the three seats filled and thought you had all three.

Cost ranges are typical US market figures and vary by size and complexity.

Who should you hire first: bookkeeper, CPA or fractional CFO?

Hire the bookkeeper first and keep a CPA for the return; add a fractional CFO when the decisions in front of you carry more money than a guess can safely handle. The order rarely changes. What changes with the size of the company is how much of each seat you need, and when the close has to reach controller standard.

These bands are our judgement from working with owner-led US companies, not an industry statistic.

Complexity moves a company up a band faster than revenue does. Inventory, several entities or states, debt with covenants, or a sale in the next two years each put you one row lower than your revenue alone suggests.

When to hire a fractional CFO instead of more bookkeeping

Hire a fractional CFO instead of more bookkeeping when the books are already current and the question has changed from "what happened?" to "what should we do?" A second bookkeeper makes the record faster. It does not tell you whether the hire, the loan or the new location pays. If the books are behind, the answer is the reverse: fix the record first, because a forecast built on it would be wrong.

The bookkeeper records the past

This is the foundation, and it is not optional. Every dollar in and out, categorized correctly, reconciled to the bank so the books match reality. Without it, nothing else works. A CPA cannot file from a mess, and a CFO cannot forecast from numbers that are wrong. Clean books are the raw material for every decision above them.

But a bookkeeper's job ends at one sentence: here is what happened. Accurate history, nothing more. It will not tell you whether the history is good, whether that product is losing money, or what to do next. Asking your bookkeeper to steer the business is like asking the scorekeeper to coach the team. Right person, wrong question.

The CPA files the past

A CPA is a licensed professional who files your returns and keeps you compliant. Backward looking, once a year, and genuinely necessary. A good CPA is worth keeping.

The problem is what owners expect from them. A CPA optimizes the return for the year that already closed. They are not in your numbers every week, they are not modeling next quarter's cash, and by design they look backward. That is the job, done well. It is just not strategy.

For the record: Korven prepares your books and tax file; our licensed CPA partner prepares, signs and files your return. If you already have a CPA, we hand them books they can file from directly, reconciled and documented, so the filing is fast and the invoice is small. We make your CPA cheaper, not redundant.

The CFO decides the future

A CFO is the only one of the three whose job is the future. Which product to kill. When cash gets tight. Whether you can afford the hire, the loan, the expansion. What breaks in eight weeks if nothing changes. The CFO takes the bookkeeper's history and the CPA's compliance and turns them into decisions.

In practice that looks like a rolling 13-week cash flow forecast that shows the week you run short before you get there, a contribution-margin view that reveals which customers and products actually pay, and a clear answer to the one question owners cannot answer alone: can we afford this, yes or no. The deliverable is not a report. It is a changed decision.

Bookkeeper vs CPA vs CFO, side by side: what each does and does not do

Each seat has a clear edge. Most of the money lost between them is lost in work that everyone assumed someone else was doing. The controller is included because, in a growing company, the close it runs is where the bookkeeper's work ends and the CFO's begins.

Two legal lines matter here. Anyone paid to prepare a federal return needs a Preparer Tax Identification Number, and only CPAs, enrolled agents and attorneys have unlimited rights to represent you before the IRS, according to the IRS guide to preparer credentials. And any accountant who files a report with the SEC must be a licensed CPA, as the Bureau of Labor Statistics notes. Bookkeeping, controller and CFO work need no license. At Korven the line sits in the same place: Korven prepares your books and tax file; our licensed CPA partner prepares, signs and files your return.

Do I need a CFO or a bookkeeper?

Start with the honest answer: if your books are behind or wrong, you need bookkeeping first. A CFO built on bad data just makes confident mistakes faster. Get the foundation clean, then look up.

You have outgrown bookkeeping alone when two or more of these are true:

• You are near or past $1M in revenue and the decisions are getting bigger than the gut can carry.
• Cash keeps surprising you. Good months feel tight, and you are not sure why.
• You cannot answer "can I afford this hire" without a guess.
• You are raising money, taking on debt, or heading toward a sale.
• You have margins you cannot explain and a best seller you suspect is not your best earner.
• A big decision is coming and there is no model behind it, only hope.

If that list stings, the missing seat is the CFO, not more bookkeeping. Most growing businesses need both, filled by different people doing different jobs.

CFO or CPA first?

Keep the CPA, fix the books, then add the CFO. Every company needs its returns prepared, signed and filed each year, so the CPA seat is never optional. A CFO comes first only when the books are already clean and the pressing problem is cash, a lender or a big decision.

If the books are behind, neither can do their job yet, and catch-up bookkeeping comes first.

Controller vs CFO: which do you need?

A controller owns the accuracy of the past: the monthly close, reconciliations, controls and the financial statements. A CFO owns the future: the cash forecast, budgets, financing and the decisions that move money. The controller's work comes first, because a forecast is only as good as the close underneath it.

Few owner-led companies need a full-time controller. In the Korven Finance Office, the monthly close and reporting do the controller's work, and a fractional CFO does the forward-looking work.

Why "fractional" exists

A full-time CFO is paid at chief-executive level: the Bureau of Labor Statistics counts CFOs among chief executives, whose median annual wage was $213,990 in May 2025, before bonus, benefits and equity. Most businesses under roughly $20M do not have a quarter of a million dollars of CFO work to do, so they skip the seat and let the owner carry it at midnight.

That is the expensive version of saving money.

A fractional CFO, also called an outsourced CFO, gives you the same senior judgment for only the hours you actually need. You get the seat without the full-time salary. Fractional and outsourced mean the same thing here: part-time access to a finance leader who has done this many times, pointed at the decisions that matter.

Bookkeeper, accountant, controller and CFO pay: what the BLS data shows

The US Bureau of Labor Statistics publishes pay and job outlook for each of these seats. The figures below are what each costs as a full-time employee, before benefits and payroll taxes, not what an outsourced service charges. For the full comparison, see in-house vs outsourced accounting.

Source: US Bureau of Labor Statistics, Occupational Outlook Handbook, pages last updated August 2026 (wages for May 2025, projections for 2025 to 2035). A median means half of workers earned more and half earned less.

Two things stand out. Each seat up the table costs more than the one below it, from about $51,000 to about $214,000 at the median, which is why owners try to stretch one person across two jobs. And the BLS projects fewer bookkeeping clerk jobs over the decade while financial manager jobs grow much faster than average. In our reading, the work is moving from recording the numbers to running the company on them.

The expensive mistake

The most common one is assuming your CPA is your CFO. They are covered on compliance and naked on strategy. Nobody is watching the cash, the margins, or the decision in front of you, and the gap does not show up until the month it costs you.

The second is waiting for a crisis to hire one. The CFO seat is cheapest to fill before you need it, because the first thing a CFO does is make sure you never hit the wall that would have forced the emergency. You are not underserved by your accountant. You are missing a seat, and it is the one that looks forward.

Where Korven fits

We cover the bookkeeping so the data is clean, and we sit in the CFO seat that most owners are missing. Korven prepares your books and tax file; our licensed CPA partner prepares, signs and files your return. Two operators who do the work themselves, no junior handoff.

You can start with catch-up bookkeeping if the books are behind, or straight into fractional CFO work if they are clean and the decisions are what hurt. If you are not sure which row of the table above you are in, a complimentary Finance Review answers it from your actual books.

Is a CPA worth it for a small business?

A CPA is worth it for a small business when tax decisions carry real money: an S corporation election, filings in several states, owner pay and distributions, a notice from a tax authority, or a return complex enough that a mistake costs more than the fee. The CPA's fee for a business return rises with its complexity.

For a simple sole proprietorship with clean books, many owners do not need a CPA all year, only at filing time. Korven is not a CPA firm: we keep your books tax-ready all year, and our licensed CPA partner prepares, signs and files business returns. See Business Tax Preparation, Without the April Scramble.
