The difference between a virtual CFO who delivers something and one who bills you monthly for slide decks usually shows up in the first conversation, if you ask the right questions. Here are the seven that matter, each with the answer a good operator gives and the answer that should worry you. Use them and the decision mostly makes itself.

Every virtual CFO will tell you they are strategic, experienced, and a genuine partner. None of that is testable. What is testable is whether they can name a deliverable, a date, and a price, and whether they will tell you what they will not do. The seven questions below are built to surface exactly that, and they work on any provider, including our own fixed-scope 90-Day Number engagement. Ask them of everyone and compare the answers side by side; the pattern usually resolves within a week.
This is the question that separates operators from retainer sellers, so ask it first. A good answer names an artefact and a date: "a 13-week cashflow forecast tied to your pipeline and payroll, in your hands and running, by day 90." A weak answer describes a relationship: "we will work closely with you across your finances and meet monthly." The second answer is a description of a retainer, not a deliverable. If they cannot name what you will hold at the end, you do not have a virtual CFO, you have a subscription.
A good answer is one number you can hear on the first call. A weak answer is a day rate, an hourly estimate, or "let us scope it and come back to you." The willingness to name a fixed price matters because of what it transfers: a fixed price moves the scoping risk onto the provider, who now wears the cost of underestimating the work, whereas an open-ended arrangement leaves that risk with you. Most of the Australian market sells open-ended retainers at $3,000 to $8,000 a month with no fixed total and no end date, so a provider who names one number is telling you something real about how they work.
You are testing for pattern recognition. A CFO who has seen ten SaaS businesses at your ARR, or ten builders carrying work in progress, will find your problem faster because they have found it before. You can hear the difference. Pattern recognition sounds like "at your stage the model usually breaks in the same two places, and I would check those first." No pattern sounds like "we work across all sectors and tailor our approach to every client." Specific beats broad, every time, because your engagement is ninety days, not nine hundred.
Ask who builds the deliverable, not who is on the sales call. For work that will face external scrutiny, a model heading into fundraise diligence or a board pack read by investors, it matters that the work is led by a Chartered Accountant (CA ANZ), because that is where technical accounting judgement gets tested by people paid to find the holes. A good answer names the person and their credential. A weak answer is a team of unnamed associates standing behind a senior salesperson you will not see again after signing.
A good provider volunteers the edges: what is included, what is not, and what a second deliverable would cost if one emerges mid-engagement. Naming the exclusions is not meanness, it is what makes a fixed price possible, and it protects you as much as them. A provider who says everything is included is either overreaching or planning to absorb the overreach into a vaguer, larger bill later. The specific answer you want sounds like "the cashflow model is in scope; if a fundraise model becomes the priority at week six, we scope that separately and you decide."
A good answer treats the end as a real option, not a formality on the way to a retainer. Some founders move to a fortnightly or monthly cadence after a project; some take the deliverable and run the next year themselves; both are legitimate outcomes and a good provider says so unprompted. A weak answer assumes you will roll onto an ongoing arrangement by default. Watch closely for the provider who is clearly selling the retainer at the front door; the project is the audition, and you are allowed to end the show.
The best question to end on, because it forces honesty. A good provider can describe failure specifically, the deliverable not landing by the date, the assumptions not surviving contact with the actuals, the founder unable to run the artefact alone afterwards, and can tell you the remedy for each, not just the definition. A provider who cannot imagine failing has either never been measured against a deliverable or is not being straight with you. Either way, you have your answer.
Founders often spend their best minutes on two questions that sound rigorous and reveal almost nothing. "What software do you use" tells you about tooling, and any competent operator works in whatever your ledger already runs on; the tool has never been the constraint. "How big is your team" rewards exactly the wrong thing, because a large team behind a small engagement usually means your file is one of forty, and the seven questions above will tell you far more about who touches your work than a headcount will. Ask them if you like. Just do not let the answers decide anything.
You do not need perfect answers to all seven. You need specific ones. The pattern to watch for is deflection: a provider who turns every question into "it depends, let us scope it" is telling you the scope was never going to be fixed and the price was never going to be named. A provider who answers with a deliverable, a date, a price, and a clear list of exclusions is one you can actually evaluate, and hold to it on day 90.

How many providers should I ask these questions of?
Two or three is usually enough. The seven questions surface the differences quickly, and once you have asked them of a few providers the pattern of who names deliverables and who sells relationships becomes obvious. More than three tends to add noise rather than clarity.
What if a provider will not give a fixed price?
That is an answer in itself. Some cannot fix a price because their model is hourly, which is a legitimate way to work but a different product. Just know that you are then buying time, not a deliverable, and the total is open-ended. If you want a fixed total, the provider who will not name one is not your fit.
Is a Chartered Accountant essential?
Not for every piece of work. For operating deliverables the quality of the artefact matters more than the letters. For anything facing external scrutiny, a fundraise model, a board pack, an audit-readiness review, a Chartered Accountant (CA ANZ) leading the work is worth insisting on, because that is where technical accounting judgement is tested.
How is a virtual CFO different from a fractional CFO?
In practice the work overlaps almost entirely, and the terms are often used interchangeably in Australia. The more useful distinction is structural: does the engagement have a named deliverable, a fixed price, and an end date, or is it an open-ended monthly arrangement? Judge the structure, not the label.
Should I ask for references?
Yes, and ask the past client what they held on the last day, whether the date held, and what the provider refused to do. Those answers are more revealing than a testimonial, because they test delivery rather than sentiment.
What is the single most important question?
The first one: what will I have at the end, and on what date? Almost everything else follows from it. A provider who can name a dated deliverable has usually already scoped, priced, and defined the work, because naming the deliverable forces all three.
Do these questions work on your own service?
Yes, deliberately. Ask us the same seven. The 90-Day Number is a fixed-scope engagement at $17,850 plus GST with a named deliverable on day 90, the work led by a Chartered Accountant (CA ANZ), and a clear set of exclusions. The questions are designed to be answerable by an operator and awkward for a retainer seller, and we would rather be judged by them.
