Fixed Price Virtual CFO in Sydney
Most Sydney virtual CFOs price on application or bill by the hour. Here is what a truly fixed price buys, when it works, and when it does not.
Ask most Sydney virtual CFOs what an engagement costs and you will get a range, a discovery call, and a proposal three weeks later. A fixed price does the opposite. It names the number, the scope, and the delivery date before you sign anything. This article is about the difference, because the difference is larger than it looks.
Published: July 2026
Fixed price is not a discount and it is not a starting figure. It means three things are locked before the work begins: the price, the scope, and the date. You know the number you will pay. You know the one deliverable you will hold at the end. You know when you will hold it.
That sounds obvious. It is rare. The standard offer in the Australian virtual CFO market is an open-ended monthly retainer at $3,000 to $8,000 per month with no named deliverable and no end date. The second most common offer is hourly: a rate card, an estimate, and an invoice that lands higher than the estimate more often than not. Neither is fixed. Both move the risk of a badly scoped engagement onto you.
A fixed price moves that risk back to the provider. If the work takes longer than expected, that is the provider’s problem, not a variation on your invoice. That single shift changes the incentives on both sides of the table.
There are honest reasons fixed pricing is uncommon, and it is worth stating them plainly rather than pretending everyone else is lazy.
Fixed pricing is harder to scope. To quote a fixed number, the provider has to define the deliverable precisely, agree the edges, and name what is out of scope. That is real work done before any money changes hands, and it only pays off if the engagement proceeds. An hourly arrangement skips all of it: start the clock, see where it goes.
Fixed pricing also lets the client leave. When the deliverable arrives on day 90 and the engagement ends, the provider has to earn the next piece of work rather than assume it. A retainer that renews by default is a more comfortable business to run.
Those are the reasons most firms avoid project-based work. We think they are also the reasons it is the better product. The scoping discipline is the value. The clean exit is the point.
A number you cannot exceed is a constraint, and constraints produce discipline. To deliver a fixed-price engagement without losing money, a provider has to do three things most retainers never require.
First, define the deliverable in a sentence. Not “strategic finance support”. A 13-week cashflow forecast tied to your actual pipeline. A fundraise-ready financial model built to survive diligence. A unit economics build that shows contribution per order or per seat. A board reporting pack you can run yourself. One artefact, named.
Second, agree the edges. What is included, what is not, and what a change would cost. A fixed-price provider will tell you upfront that a second deliverable is a second engagement, because absorbing scope creep into a fixed fee is how fixed-price work goes broke. That honesty protects both sides.
Third, work to a date. Day 90 is not aspirational. It is the term of the engagement. The forecast, the model, or the pack exists on that date, or the engagement has failed its only test.
Our front-door product, the 90-Day Number, is a fixed-price engagement. It is $17,850 plus GST, payable in three instalments of $5,950. It delivers one named deliverable on day 90. There is no retainer, no auto-renewal, and no scope creep.
The number is public because publishing it is part of the point. When the price is fixed and visible, you can compare it against the two real alternatives before you spend an hour on a call.
The first alternative is the full-time hire. A genuine CFO in the Sydney mid-market does not come cheap. Base salaries for the role sit well above six figures, and the Robert Half 2026 Australia Salary Guide reports finance leadership pay rising on the back of a sustained shortage of qualified candidates. Once you add the 12% superannuation guarantee (the rate that took effect on 1 July 2025, per the ATO), annual leave, recruitment fees, and any bonus or equity, the all-in cost of a full-time CFO for a business at this stage lands comfortably in the $200,000 to $300,000 range. That is the right hire above roughly $25M in revenue. Below it, the 40-hour week is rarely the constraint.
The second alternative is the open-ended retainer. At $3,000 to $8,000 per month, a year of retainer costs between $36,000 and $96,000. That can be money well spent, but only if you can name what it produced. The failure mode is ten months of monthly calls and a folder of slide decks that changed no decision.
Against both, a fixed-price project reframes the question. You are not buying hours or attendance. You are buying one artefact, for one number, by one date.
Fixed pricing is not always right, and a provider who claims otherwise is selling. It works when the problem can be defined. It does not work when the problem is truly undefined.
If a business is mid-crisis and nobody yet knows what the core problem is, a scoped 90-day deliverable is the wrong tool, because you cannot scope a deliverable for a question you have not framed. If a business needs a finance leader in the operating seat every week for the foreseeable future, that is an ongoing capability, not a project, and an ongoing engagement or a full-time hire fits better. And if the real need is bookkeeping, compliance, or day-to-day transaction processing, that is not virtual CFO work at all and should be priced and delivered as what it is.
The honest position is that fixed pricing suits a defined deliverable. Most of the questions a $2M to $15M founder actually needs answered, whether to make the next two hires, whether the raise is survivable, whether a product line is losing money, are definable. That is why the model fits the segment.
A public, fixed price is a stance, not a promotion. It says the work has been productised enough to name, and that the provider is willing to be measured against a number and a date. In a market that prices on application, that is the differentiator, and it is one you can verify before you ever pick up the phone. For more on why we do it, see why we publish our price.
Is a fixed price the same as a cheap price?
No. Fixed means the number does not move, not that it is the lowest. A fixed-price project can cost more than a month of retainer or less than a full year of one. What it removes is the uncertainty, not the cost.
What happens if the work takes longer than expected?
That is the provider’s risk under a fixed price, not yours. The fee does not change because the engagement was harder to deliver than scoped. This is the core difference from hourly billing, where the overrun lands on your invoice.
How is a fixed price virtual CFO different from a fractional CFO?
The pricing model, mostly. Fractional and virtual CFO work often overlap in what gets done. The difference here is that the engagement is scoped to a single named deliverable, fixed in price at $17,850 plus GST, and finished on day 90, rather than sold as an open-ended monthly arrangement.
Can complex work really be fixed-priced?
If the deliverable can be named, yes. A fundraise-ready model is complex and entirely scopable: the sheets, the drivers, and the diligence questions it must survive are known in advance. What cannot be fixed-priced is an undefined problem, and a good provider will tell you when that is the situation you are in.
What does the fixed fee include?
One named deliverable built and handed over, along with the working sessions and stress-testing needed to produce it. It does not include a second deliverable, ongoing monthly work, or bookkeeping and compliance tasks. Those are scoped separately.
Who does the work?
The work is led by a Chartered Accountant (CA ANZ). That matters most where the deliverable has to survive external scrutiny, such as a model heading into fundraise diligence.
What happens after day 90?
You decide. Most founders move to a fortnightly or monthly cadence once the deliverable is in hand. Some take the artefact and run the next twelve months themselves. Both are correct outcomes, and there is no auto-renewal that assumes one for you.
