Fractional CFO vs Bookkeeper vs CPA.

Written by Azhar Jaffri, Co-Founder and Finance Lead · Published · Updated

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.

Role What they do Question they answer Typical cost
BookkeeperRecords every transaction, reconciles the accounts. The past, monthly.What happened?A few hundred to about $2,000 / month
CPAFiles returns, keeps you compliant. The past, yearly.What do we owe?An annual filing fee
Fractional CFOForecasts, plans, decides. The future, weekly.What do we do next?A fraction of a full-time CFO ($200k+)

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

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 does not file returns. That is your CPA's job. What we do is hand your CPA 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.

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.

Why "fractional" exists

A full-time CFO costs $200,000 to $400,000 a year in salary alone, before 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 entirely 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.

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, we hand your CPA a return they can file fast, and we sit in the CFO seat that most owners are missing. 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.

Questions, Answered.

What is the difference between a bookkeeper, a CPA and a fractional CFO?+
A bookkeeper records what happened and reconciles your accounts, looking at the past every month. A CPA files your tax returns and keeps you compliant, looking at the past once a year. A fractional CFO looks forward: forecasting cash, planning decisions, and telling you what to do next. The bookkeeper answers what happened, the CPA answers what you owe, the CFO answers what you do next.
Do I need a CFO or a bookkeeper?+
If your books are behind or wrong, start with bookkeeping, because nothing else works without clean data. You need a CFO on top of that once decisions get expensive: you are near or above $1M in revenue, cash keeps surprising you, you cannot say whether you can afford a hire or a loan without guessing, or you are raising money. Most growing businesses need both seats. They are different jobs.
What does a fractional CFO actually do?+
A fractional CFO turns your numbers into decisions. They build and roll a cash flow forecast, model whether you can afford a hire or an expansion, find the products and customers that actually make money, prepare you for a loan or a sale, and tell you the week something breaks before it breaks. The deliverable is not a report. It is a changed decision.
How much does a fractional CFO cost?+
A full-time CFO typically costs $200,000 to $400,000 a year in salary alone, before benefits and equity. A fractional or outsourced CFO gives you the same senior judgment for only the hours you need, which for most growing businesses is a fraction of that. You get the seat without the full-time salary.
Is a fractional CFO the same as an outsourced CFO?+
Yes. The terms are used interchangeably. Both mean a senior finance leader who works with your business part time, on the specific decisions that need them, instead of sitting on your payroll full time.
Can my CPA be my CFO?+
Rarely, and not in the same engagement. A CPA is trained to file compliant returns and look at the year that closed. A CFO looks forward and lives in your numbers weekly. Assuming your CPA covers strategy is the most common and expensive gap we see: you are covered on compliance and exposed on decisions.
When should a business hire a fractional CFO?+
Before the crisis, not during it. The practical trigger is when a wrong financial decision would hurt: a hire you are not sure you can afford, a loan, an expansion, a fundraise, or cash that keeps catching you off guard. If a bad call costs more than the CFO does, it is time.
Does Korven file tax returns?+
No. Filing is your CPA's job, and a good CPA is worth keeping. Korven handles bookkeeping, financial reporting and fractional CFO work, and we hand your CPA books they can file from directly, so the filing is fast and the invoice is small. We make your CPA cheaper, not redundant.
You have a bookkeeper and a CPA and still fly blind.
