The question isn't "do we need a CFO?" — most owner-led businesses reach a point where they clearly do. The question is whether you need one full-time, or whether a partner-led fractional CFO gives you the same output at a fraction of the cost and commitment.
What each role actually does
Both a fractional and a full-time CFO do the same work: they own cash and forecasting, translate the business into defensible numbers, and carry those numbers into the boardroom and in front of investors. The difference is structure, not seniority.
A full-time CFO is a permanent, salaried executive — the right answer once finance is complex enough to need daily senior ownership and a team beneath it. A fractional CFO delivers the same leadership on a part-time, scoped basis: enough senior time to run the finance function well, without the fixed cost of a full-time hire before the business can absorb it.
Neither replaces your bookkeeper or accountant. Those roles record history; the CFO manages the future. Most businesses that engage us already have a competent accountant — what they lack is someone who owns the forecast and the story.
The cost comparison
A full-time Group CFO in this region typically costs $100K–$180K+ per year in salary alone, before bonus, equity, benefits, and the ramp-up time to hire. A fractional engagement delivers comparable — often greater — output, scoped to exactly what you need:
| Fractional CFO | Full-time CFO | |
|---|---|---|
| Annual cost | A fraction of a full-time salary; scoped to need | $100K–$180K+ salary, plus bonus/equity/benefits |
| Time to value | First deliverable in week one; dashboard live by day 30 | Weeks to hire, then months to ramp |
| Seniority | Partner-level from day one | Depends on what the salary attracts |
| Commitment | Scales up or down with the business | Fixed overhead regardless of workload |
| Best fit | $2M–$30M revenue; raising, restructuring, or professionalising | Larger, complex operations needing daily ownership + a team |
Signs you've outgrown a bookkeeper
You probably need CFO-level judgment — fractional or full-time — when:
- You're losing cash you can't fully explain, and a 13-week forecast doesn't exist.
- A bank or investor has asked for financials you don't have in a form they'll accept.
- You're making decisions on incomplete numbers — no monthly dashboard, no scenario view.
- Growth is creating chaos, not just revenue, and no operating model scales with it.
- You're heading toward a raise, a bank facility, or an exit and the numbers need to withstand diligence.
Rule of thumb
If you need senior finance judgment but a full-time CFO would sit idle half the week — or you can't yet justify the salary — start fractional. You can always graduate to full-time once the workload genuinely fills the role.
What you don't get part-time
Honesty matters here. A fractional CFO is not on-site every day, and won't build out a large in-house finance team for you. If your business genuinely needs daily executive presence, real-time treasury management across many entities, or a growing department to lead, a full-time CFO is the right call. The fractional model works precisely because most $2M–$30M businesses don't need that yet — they need the judgment, the systems, and the accountability, delivered by someone who has done it before.
How Core Advisors engages
We start most relationships with a fixed-scope Diagnostic — a 2–3 week review of your cash cycle, controls, and financial model, ending in a prioritised 90-day roadmap. From there, a 90-Day Foundation installs the finance function, or an Embedded CFO retainer runs it ongoing. Every engagement is partner-led: the person who takes your first call owns the work end to end. You can see the track record or read more about our fractional CFO services.
