Most business owners start asking this question somewhere between $2M and $10M.
The team has grown. The numbers have grown. The decisions have grown with them. And somewhere along the way, the gap between what your accountant tells you in May about last financial year and what you actually need to call on this Tuesday has turned into a real cost.
Most owners don't start searching for a CFO, though. They start somewhere earlier: an accountant who takes weeks to reply, or someone who handles the compliance but goes quiet the moment the question gets strategic. The search for CFO-level thinking often starts as a search for better: a better relationship, better answers, better visibility into where the business actually stands. The title comes later.
So you start looking, and the titles blur: CFO, fractional CFO, virtual CFO, advisory accountant. The job descriptions overlap. The price points don't. And the outcomes vary more than most owners realise.
Here's how to think about it.
The signal you actually need one
It's rarely a revenue number. Revenue is a lazy proxy: it tells you the business is bigger, not that the financial side of it is straining.
The real signal is when the numbers start running you instead of the other way around. You feel it as:
- Cash tighter than it should be in months you thought were strong
- Decisions made on instinct because the data shows up too late
- Big calls on headcount, pricing, or capex sitting unmade because no one has modelled the impact
- A nagging feeling, underneath it all, that you're flying without instruments
For a lot of Australian businesses, the trigger is a specific moment: a BAS quarter that hurt more than it should have, a tax instalment that caught them off guard, or realising they're about to make a significant hiring or capital decision with no model to run it through first. The compliance is being handled. The forward picture isn't.
If two or more of those signals are true, the financial side of your business has moved past the setup that got you here. That's the trigger, not the line at the top of the P&L.
What a CFO actually does
A CFO is not a senior accountant. The work is structurally different.
An accountant tells you what happened. A bookkeeper records what happened. A CFO tells you what's likely to happen next and what to do about it.
In practice, that includes:
- A rolling forecast that connects sales, margin, capacity, and cash
- Pricing and margin work that protects profit as revenue grows
- A view on capital structure so you can fund growth without giving away the business
- A reporting cadence the leadership team can actually use
- Pressure-testing the big calls before they get made, not after
It's a thinking partner role with the numbers as the lens. The output is better decisions, faster.
Full-time CFO, fractional, or advisory: which fits?
The real question isn't which title to hire. It's what level of financial leadership the business needs right now, and how it's best delivered.
Full-time hire. This makes sense when the role is genuinely full: a business doing well north of $20M, with enough complexity and transaction volume to keep a sharp operator busy five days a week. Below that threshold, a full-time hire is usually a mismatch. You either underpay and end up with someone the role is too large for, or you pay properly and spend half your time finding work to fill the seat.
Fractional or virtual CFO. This is the model that fits most private businesses in the $1M to $20M range. A fractional CFO works with you on a regular cadence, typically one to four days a month. Embedded enough to know the business, not on the payroll. The right arrangement brings senior-grade thinking without the senior-grade overhead.
In practice: monthly reporting and forecast review with the leadership team, a structural plan that updates as the business moves, input on the calls that matter (pricing, hiring, capex, debt, deals), and coaching for whoever handles the day-to-day so that layer runs cleanly.
Most owners at this stage don't need a CFO every day. They need a CFO for the decisions that matter, and a clean operating rhythm for everything else.
Advisory support alongside what you already have. Sometimes the business already has someone in the finance seat: a CFO, a financial controller, a capable finance manager. But there are situations where outside perspective earns its keep: a capital raise, a potential acquisition, an exit process, board reporting that needs to step up, or a strategic question where an independent view changes the conversation.
In those cases, the internal person isn't the problem. The business needs bolt-on expertise for a specific piece of work, and the two relationships sit alongside each other. It's a common arrangement, and one that often gets underused.
What good actually looks like
Most owners who haven't had this kind of support before don't have a frame of reference for what it looks like in practice. Here's the arc.
Month one: the diagnostic. Before anything else, get a clear picture of where the business actually stands. We run a thorough review of accounting and finance procedures, corporate structure, and organisational setup, working through performance, liquidity, and growth analyses to understand what the business is actually doing. The good, the bad, the ugly. Most owners find something here they didn't know was there: a margin eroding quietly, a debtor book running longer than the terms say, a structural issue that's been quietly limiting the options. The diagnostic isn't about fixing anything yet. It's about a clear understanding of where things stand, compiled findings, and targeted recommendations on what needs to change first.
Then: the strategic plan. Once the current picture is clear, the next step is a comprehensive planning session. Three to five year targets, annual goals, and a 90-day action plan. If there are multiple directors or a leadership team, this session aligns everyone around the same financial targets, values, purpose, and vision. Most businesses have never done this properly. Getting the whole leadership team pointed at the same destination, with real numbers attached, changes how the day-to-day runs.
Then: the financial model. The strategic plan needs numbers wrapped around it. We build a financial model that supports ongoing planning, reporting, and forecasting, including cash management. It maps the path from where the business is now to where it's heading: growth targets, the headcount that supports them, capital requirements, working capital at each stage. For businesses raising finance from banks or investors, the model does double duty: it's the operational tool and the due diligence package in one. You can see what the business needs to generate, when it needs capital, and what the milestones actually look like.
Ongoing advisory and accountability. From there, the rhythm sets in. Monthly advisory meetings to hold the business accountable to the action plans and budgets set in the planning session. We update the financial model, run management reports, and provide CFO-level oversight: accounting and performance commentary that gives a real view of whether the business is on track. The conversations shift as the business moves: capacity and hiring, capitalisation and debt structure, pricing reviews, specific transactions, exit planning. The numbers inform the decisions instead of arriving after them.

How to choose
Three questions worth pressure-testing before committing to anything:
-
Is this full-time work, or peak-and-trough work? If you can see peaks coming (a raise, a sale, a restructure) with quieter stretches between, a fractional or advisory relationship will serve you better than a hire who sits idle in the gaps.
-
Do you want a hire, or a relationship? A hire sits inside the business, on your payroll, with all the management that comes with that. A relationship sits beside it: outside-eyes accountability, and the flexibility to scale up or down as things change.
-
Where's the bottleneck right now? If it's data and rhythm, a fractional engagement fixes it fast. If it's a specific transaction with a hard deadline, you need someone with deal experience. If it's the financial leadership of a business already past $20M, a full-time hire probably earns its keep.
Most owners I work with land on a relationship model, and stay there for years. The work compounds. The trust compounds. The numbers start informing decisions instead of just reporting them.
A starting point
If you're sitting with this question, a good first move is a financial diagnostic: a few weeks of work, end to end, that tells you exactly where the business stands and what the next twelve months need to look like. Whether you go full-time, fractional, or advisory after that is a much easier call once the picture is in front of you.

Questions that come up early
Three we hear often.
What's the difference between a fractional CFO and an advisory accountant? In practice, the distinction is often overstated. What matters is whether the person you're working with is operating at the strategic level (forecasting, capital structure, pressure-testing the big calls) or just handling compliance. A well-run fractional CFO engagement and a high-quality advisory relationship cover much of the same ground.
When does a full-time CFO hire actually make sense? When the role is genuinely full: usually a business north of $20M with sustained complexity and transaction volume. Below that, you're often paying for capacity the business can't keep loaded.
We already have an internal CFO. Can you still work with us? Yes. There are situations where an internal CFO benefits from outside advisory support: a capital raise, an acquisition process, a strategic question that needs an independent view. The models aren't mutually exclusive.
