What does a fractional CFO cost in Australia, and when does it pay for itself?

Most fractional CFO engagements in Australia sit between $3,000 and $8,000 a month, with construction usually landing in the upper half of that range. Hourly arrangements run $150 to $400. The useful question isn't the fee — it's whether the work behind it recovers more than it costs, which on a $10M builder it usually does inside two claim cycles.

That's the short answer. The longer one matters more, because "what does it cost" is the wrong first question and most builders ask it anyway.

What does a fractional CFO actually cost in Australia?

There are four ways this gets priced in the Australian market, and they behave differently.

Fixed monthly retainer — $3,000 to $8,000 a month for construction. Suits a business that wants a predictable monthly rhythm. The catch is that you pay in quiet months too.

Hourly — $150 to $400 an hour. Suits one-off work: a bank submission, a restructure, a single messy project. The catch is that nobody rings the CFO when the clock is running, which is exactly when you should.

Day rate — $1,500 to $3,000 a day. Suits short intensive engagements. Hard to sustain a monthly discipline on.

A full-time CFO — $250,000 to $350,000 all-in. Makes sense past roughly $50M with real complexity. Takes six to nine months to hire, and you own the mistake if it doesn't work.

Published Australian ranges cluster tightly around these numbers. General SME engagements can start nearer $3,000, while complex multi-entity work runs past $15,000 a month. Construction sits high in the range for a specific reason.

Why do construction engagements cost more?

Because there is more to do, and most of it is monthly rather than annual.

A retail business has one set of numbers. A builder running six jobs has seven — one per project plus the consolidated view. Every month somebody has to re-estimate cost-to-complete on each job, reconcile the WIP position, chase approved and unapproved variations, and rebuild a cash forecast around progress-claim timing that shifts constantly. Retentions sit at 5 to 10 per cent of contract value for a year or more and have to be tracked individually.

None of that exists in a normal SME engagement. It is why a generic fractional CFO priced at the bottom of the range is frequently the more expensive option — they will produce a tidy P&L and miss the job that's fading.

What should be included for the fee?

Ask for this list specifically, and be suspicious of anything that answers in hours rather than outputs: a monthly reporting pack with project-level forecast margin, not just business-wide results; a WIP schedule refreshed monthly and reconciled to claims; a rolling 13-week cash flow forecast; a standing meeting to actually discuss the numbers, because reports nobody talks through change nothing; pricing and tender input before you bid rather than after you've won; and access when a decision lands mid-month.

If cash forecasting or WIP is quoted as an extra, the base fee isn't the real fee.

How do you work out whether it pays for itself?

This is the calculation nobody does, and it is not complicated. Take the three places construction money actually leaks and estimate each conservatively.

Margin recovery. Profit fade in Australian commercial construction routinely runs 5 to 12 margin points between tender and final account. You do not need to eliminate it. On a $10M builder, catching three points of fade on one $2M job six months early is $60,000 — and that is one job, once. We've written about where that margin actually goes.

Unclaimed variations. Every builder we open the books on has variations that were built and never priced. Weak variation capture commonly leaves $80,000 to $200,000 on the table across a year.

Financing cost. If you are covering timing gaps with an overdraft or invoice finance, you are paying an effective 8 to 15 per cent for the privilege. Collecting ten days faster on $10M of revenue frees roughly $26,000 a year in working-capital cost, before you count the nights you stop worrying about payroll.

Add your conservative numbers. If the total is not comfortably more than twelve months of fees, don't engage — and say so out loud to whoever is quoting you. Our value calculator runs this in about two minutes if you'd rather not do it on paper.

A worked example

A $12M commercial builder, five concurrent jobs, blended margin 11 per cent, no monthly WIP, claims paying at 58 days against 30-day terms.

One job re-forecast in month two shows margin at 7 per cent, not 11. Caught early, two of those four points are recoverable on a $2.6M job: $52,000. A variations review across the current jobs surfaces $95,000 built but never claimed; assume half is recoverable: $47,500. Claim discipline pulls collections from 58 days to 45, which on $12M is roughly $28,000 a year in reduced financing cost.

That's $127,500 against a fee somewhere near $72,000 a year at the top of the range. The margin catch alone covers it. And the second year costs the same but starts from a system that already exists.

The honest caveat: those numbers are the upside case for a business that currently has no project-level reporting. If you already run monthly WIP and forecast margin properly, the return is much smaller — which brings us to the next bit.

When is a fractional CFO not worth it?

Three situations, and any decent adviser will tell you so.

You're under about $2M turnover. The complexity usually isn't there yet. A good bookkeeper with a properly configured file and a quarterly session with your accountant will cover you.

You already have the discipline. If you produce a monthly WIP schedule, forecast margin per job, and know your cash position thirteen weeks out, you have most of the value already. You might want a periodic review, not a monthly retainer.

The problem is actually a bookkeeping problem. If your Xero file can't produce job-level numbers, that's a one-off setup fix. Paying a CFO retainer to work around a broken file is expensive. Fix the file first.

What makes the fee move?

Number of concurrent projects, number of entities, the state of your accounting file, and whether anyone needs the reporting externally — a bank, a surety, or an insurer running home-warranty eligibility. A builder with three jobs and clean books sits at the bottom of the range. Four entities, twelve jobs and a file nobody has touched properly in two years sits at the top, and the first three months cost more effort than the rest of the year. Getting project profitability tracking and cash flow forecasting working is usually the bulk of that early effort.

Frequently asked questions

How much does a fractional CFO cost in Australia?

Most engagements run $3,000 to $8,000 a month on a fixed retainer, or $150 to $400 an hour. Construction businesses typically sit in the upper half of that range because project-level WIP, retentions and progress-claim timing add monthly work that a standard SME engagement doesn't have.

Is a fractional CFO cheaper than a full-time CFO?

Substantially. A full-time construction CFO costs $250,000 to $350,000 all-in once you include super, bonus and on-costs. A fractional arrangement delivers the same monthly decisions for a fraction of that, and you can scale it up or down without a redundancy conversation.

What's the difference between a fractional CFO and my accountant?

Your accountant looks backwards and works to a compliance deadline. A CFO looks forwards and works to a decision. Both are necessary. If your accountant is producing job-level forecast margin and a rolling cash flow, they're doing CFO work and you should keep them.

How long before a fractional CFO pays for itself?

Visibility arrives in the first month — the forecast and WIP position. Cash and margin improvements typically follow within one to two claim cycles, because the leaks become visible and someone finally owns them. If nothing has changed by month four, the engagement isn't working.

Do I need a fractional CFO or a better bookkeeper?

If your numbers are accurate but nobody acts on them, you need a CFO. If your numbers can't be trusted or can't be produced by job, you need the file fixed first — that's a bookkeeping and setup problem, and it's usually a one-off. Paying a retainer to work around a broken file is the most common waste we see.
