What a fractional CFO actually does
Almost every owner has an accountant. And yet a huge share of them can't confidently answer simple questions: is this price profitable for me? Can I afford another hire? Am I growing, or just turning more money? That isn't a sign the accountant is doing a bad job. It's a sign that bookkeeping and financial management are two different things — and you have one, but not the other.
The difference that changes everything
The accountant records: keeps the books, files statements, makes sure you're compliant. That's necessary, but by nature it's looking backward — what happened last month, last year. A fractional CFO takes the same numbers and turns them into forward-looking decisions: what they mean, where the risk is, what to do next. One answers the question "what happened?"; the other, "what should we do?".
What a fractional CFO specifically does
The work isn't abstract. These are the things they set up and hold:
- Management reports for you — not statements for the state, but a handful of numbers that tell you each month whether the business is heading in the right direction.
- Margins and profitability — by product and by client. Which actually brings profit, and which just brings revenue. Often twenty percent of clients drive most of the result.
- Breakeven point — how much you have to sell to avoid running at a loss. Surprisingly many owners don't know this number.
- Cash flow and planning — the difference between profit on paper and money in the bank. Many healthy businesses have hit a cash crisis with profit on the books and no cash for payroll.
- Pricing — through cost, market, and value-based approaches, so pricing becomes a decision rather than an instinct.
- Budget and variance — a plan for revenue and expenses, and a monthly comparison against reality, so you know where you're deviating and why.
- Dashboard of indicators — a handful of key numbers you track regularly, instead of managing by feel.
- Preparation for big steps — financing, growth, or a sale. For a sale, that also means a clean, normalised picture the buyer can trust.
When it makes sense to bring one in
It isn't a matter of size but of phase. It makes sense when you're making decisions where the numbers are missing — a hire, a price, an investment — and you're relying on feel. When the month ends better or worse without a clear reason. When you're growing, but you can't tell whether the growth brings profit or just more work. And especially before a big step — financing, an acquisition, or a sale — where a clean picture directly affects the outcome. If none of that sounds familiar, you probably don't need one yet. If several do — that's the moment.
What a fractional CFO isn't
It isn't bookkeeping and it isn't a tax return. It doesn't replace your accountant — it works alongside them. The accountant provides the tidy data; the CFO turns it into clarity and decisions. If someone offers you a "fractional CFO" who is really just keeping the books, that isn't it.
The rule is simple: if a number doesn't affect any of your decisions, it's just information. The CFO's job is to turn information into decisions.
Where to start
If you want one report almost every owner is missing, it's the combination of cash flow plus breakeven. With those two you immediately know whether you have money when you need it, and how much you have to sell to keep going. Everything else builds from there.
