Why Most Virtual CFO Engagements Are Retainers Wearing a Hat | Sydney Virtual CFO
Most Australian virtual CFO engagements are open-ended retainers with no named deliverable. The day-90 test, why the market sells it, and the fixed-scope alternative.
Published: June 2026
The standard virtual CFO offer in Australia is $3,000 to $8,000 per month, open-ended, scoped as "strategic finance support". Ten months into the typical engagement, the founder has spent $30,000 to $80,000 and, asked what they are holding that they were not holding in month one, points to a folder of slide decks. This article is about why that happens, why it is a structural problem rather than a provider problem, and what the alternative looks like.
Here is the test we apply to any finance engagement, including our own: at day 30, can the founder say what they got for the money? Not what was discussed. Not how many meetings happened. What exists now that did not exist before.
Most retainers fail the test, and not because the people are lazy. They fail because the contract does not require an answer. "Monthly reporting and strategic insights" is a cadence, not a deliverable. When the scope is a cadence, the engagement succeeds by occurring. The meetings happen, the deck gets presented, the invoice goes out, and everyone involved can honestly say the engagement is "going well", because going is all it promised to do.
The retainer model dominates the Australian virtual CFO market for reasons that make complete sense from the provider's side of the table.
Retainers are easier to scope. "Support as required" cannot be mis-scoped because it promises nothing specific. A project, by contrast, forces the provider to define the artefact, estimate the build honestly, and absorb the risk of getting that estimate wrong.
Retainers are better revenue. A $5,000 monthly retainer is $60,000 a year of predictable income per client. A fixed project is $17,850 plus GST, once, and then the founder gets to leave. Recurring revenue is worth more to the firm, which is exactly why the firm prefers it.
Retainers avoid the day-90 test. On a project, day 90 arrives and you have the deliverable or you do not. There is no equivalent moment in a retainer. The engagement is never finished, so it can never have failed.
None of this is a scandal. It is rational firm economics. But notice that every one of those reasons benefits the provider, and none of them benefits the founder. We are one of the few project-based virtual CFOs in Australia, and the honest version of why is simple: the reasons most firms avoid project work (it is harder to scope, the founder can leave at day 90) are also the reasons it is the better product.
Take a hypothetical $6M Sydney business on a $5,000 monthly advisory retainer. Month one: an onboarding review and a deck summarising what the founder already knew. Months two through nine: a monthly meeting, a refreshed deck, commentary on results that already happened. Somewhere around month four, the founder asks for a proper cashflow forecast. It is discussed. A simplified version appears in month six as three slides. It is not a model the founder can run; it is a picture of one.
Total spend at month ten: $50,000. Artefacts in the founder's hands: none they can operate. The forecast the business actually needed, a working 13-week cashflow model with documented assumptions, was never built, because building it is a project, and the retainer is structured to convert every project into a topic.
This is the founder we meet most often, and it is the founder behind sign seven of the warning signs article. They do not arrive sceptical of finance work. They arrive sceptical of finance engagements, which is a rational response to having bought one.
If your virtual CFO cannot tell you the deliverable on day 90, you do not have a virtual CFO. You have a retainer.
That sentence is the whole argument. CFO work that matters is project-shaped: a forecast gets built, a model gets built, a board pack gets designed, a unit economics base gets established. Each has a start, an end, and an artefact. The recurring part of finance, maintaining and interrogating those artefacts, is real work too, but it is the second purchase, not the first. The market sells the second purchase to founders who never received the first.
The 90-Day Number is $17,850 plus GST. Fixed fee, fixed scope, fixed timeline. The deliverable is named before the engagement starts, chosen from four options: a 13-week cashflow forecast, a fundraise-ready financial model, a unit economics build, or a board reporting pack. The work is led by a Chartered Accountant (CA ANZ). The full breakdown of each deliverable is published, because a named deliverable you cannot inspect in advance is just a retainer with better marketing.
On day 90 you have the artefact, the assumptions documented, and a handover that lets you run it without us. If we cannot tell you the deliverable on day one, do not hire us. That is the test.
And then the part the retainer model gets backwards: after day 90, you decide what comes next. Most founders want a fortnightly or monthly cadence at that point, because the artefact is now worth maintaining. Some take the deliverable and run the next 12 months on their own. Both are correct outcomes. The ongoing engagement, where it happens, is earned by the project, not bundled in front of it.
Whether you talk to us or anyone else, four questions sort the projects from the retainers wearing hats:
What will I be holding on day 90 that I am not holding today? A named artefact is a pass. "Improved visibility" is a fail.
Who builds it? The person in the sales meeting or someone three levels down? You are entitled to know whose hours the fee buys.
What does it cost, as one number? "From $X" and "depends on scope" both mean the scope is not actually defined. A defined scope has a price.
What happens at the end? An engagement with no end has no test. If the answer is "we just continue", you now know what the product really is.
Founders weighing the structural options more broadly should read the cost comparison across hire, retainer, and project and, where the real question is the full-time seat, the virtual CFO versus full-time hire decision.
What is wrong with a virtual CFO retainer?
Nothing, when it maintains artefacts that already exist. The problem is sequencing: most retainers are sold as the first purchase, before any forecast, model, or reporting structure has been built, and the contract never requires those builds to happen.
Are all monthly CFO retainers a bad product?
No. A retainer maintaining a built model, with a defined cadence and defined outputs, is a legitimate second product. The test is whether the foundational artefacts exist and whether the monthly fee maps to named outputs.
Why do most Australian virtual CFOs sell retainers instead of projects?
Retainers are easier to scope, produce recurring revenue, and never face a day-90 test. Those are provider-side benefits. Project work is harder to scope and the founder can leave at the end, which is exactly why it is the better product for the founder.
What is the 90-Day Number?
A fixed-scope virtual CFO engagement at $17,850 plus GST: one named deliverable on day 90, chosen up front from a 13-week cashflow forecast, a fundraise-ready financial model, a unit economics build, or a board reporting pack.
What happens after day 90?
The founder decides. Most move to a fortnightly or monthly cadence because the artefact is worth maintaining; some run the deliverable themselves for the next year. There is no auto-renewal and the ongoing engagement is scoped separately.
How do I get out of a retainer that is not delivering?
Check the notice terms, then apply the day-30 test in writing: ask the provider to name the artefact the next 90 days will produce. A good provider will either name one or agree the engagement has run its course.
Is project-based virtual CFO work really rare in Australia?
Yes. The Australian market is built almost entirely on monthly retainers at $3,000 to $8,000 per month. Fixed-scope, fixed-fee, named-deliverable engagements are the exception, which is the gap this firm was built for.
