The number was 73 per cent, not 67. I remember the founder going quiet for a moment when it landed, because a week earlier they had told me, with some certainty, that the two hires their delivery lead had been asking for were not affordable this year. They were affordable. They had been affordable the whole time. The margin that would pay for them had been sitting in the accounts, mislabelled, for about two years.

This was a specialist services business, a bit over $5M in revenue, a team in the low twenties. Good business, careful founder, the kind who reads the P&L every month and mostly trusts it. And the P&L said gross margin was around 67 per cent, which is a perfectly respectable number for the kind of work they did, so nobody had ever had a reason to look harder at it. That is the thing about a respectable number: it does not ask to be questioned.

I was not looking at the margin because I suspected it. I was rebuilding it because the engagement was a unit economics build and you cannot do that without taking the cost of delivery apart properly. When I did, the six points fell out almost immediately, and they were not hiding anywhere clever. A meaningful slice of senior people’s time, the business-development hours, the internal and admin time, the work that wins and runs the company rather than the work that is delivered to a client, had been coded into cost of delivery. It sat above the gross margin line, dragging it down, when most of it belonged below the line as overhead. Once the truly recoverable delivery cost was separated from the time that was really the cost of running the business, the true cost of delivery was lower, and the gross margin was 73 per cent.

It was not an error anyone should feel bad about. It was a coding decision made when the business was half the size, when the founder did most of the delivery themselves and the distinction between delivery time and running-the-business time did not really exist. The business grew; the coding did not change with it. That is the ordinary way these things happen. Nobody is careless. The number just quietly stops meaning what it used to mean, and no monthly reading of a respectable figure will tell you so.

Here is what six points meant in cash. At a bit over $5M in revenue, six points of gross margin is a little over $300,000 a year. The two hires the founder had told me were unaffordable came, loaded, to almost exactly that. So the hiring decision they had been circling for two quarters, the one the delivery lead kept raising and the founder kept deferring, was not really a decision about risk appetite or timing or whether the business was ready. It was a decision resting on a margin number that was wrong by the precise size of the two salaries. The affordability they were waiting for was already there. They had been managing away from a number that would have said yes.

I have started to think this is the more common shape of the problem than anyone admits. Founders believe they are arguing about strategy when they are actually disagreeing about a number nobody has measured. The founder and the delivery lead in this business were not, at bottom, arguing about growth philosophy or how much to invest ahead of revenue, though it felt like that to both of them and the conversation used all the words of a strategy debate. They were disagreeing about whether the business could afford two people, and neither of them had a reliable version of the one figure that settles it. The argument had all the texture of a values disagreement and none of the substance, because underneath it was an unbuilt number.

You see this once and you start seeing it everywhere. Two capable people, each convinced the other is being reckless or timid, both sincere, and the disagreement is not really about judgement at all. It is about a figure that has never been built properly, so each of them is filling the gap with instinct, and their instincts differ because instincts do. The debate cannot resolve, because there is nothing at the centre of it to resolve against. Months go by. The hire is deferred again. The delivery lead grows quietly frustrated. None of it is a strategy problem. It is a measurement problem wearing a strategy costume.

What struck me most, after this one, was how little persuasion the number required to do its work. I did not have to argue the founder into the hires. I did not make a case. I showed them 73 per cent and where the six points had been, and the argument they had been having with their delivery lead for two quarters simply ended, because the thing they had been arguing about was gone. That is the part I keep coming back to. A verified figure does not win the argument. It removes it. There is nothing left to debate once the number everyone was guessing at is sitting on the table, built the same way twice and holding up.

That is most of what this work is. Not insight, not strategy, not the things the category likes to sell. Just building the two or three numbers a business is actually deciding on, properly, so the founder stops arguing with themselves and their team about a figure none of them had. The six points were not clever. They were only ever a coding decision that outlived the business it was made for. But they were the difference between two hires happening and two hires being deferred another year for no reason anyone could have defended if the number had been on the table.

If you are deferring a decision because you cannot quite afford it, it is worth asking whether you have actually built the number that tells you so, or whether you are managing away from a figure you have never checked. Sometimes the answer really is no, you cannot afford it. But sometimes the margin has been there for two years, mislabelled, and the only thing standing between you and the decision is a number nobody thought to rebuild.

Rhys, Sydney Virtual CFO

The 90-Day Number is a fixed-scope virtual CFO engagement: one named deliverable, $17,850 plus GST, in three instalments of $5,950. A unit economics build, like the one in this letter, is one of the options. If you want to know more, the 90-Day Number page is the place to start.

This letter describes an engagement in anonymised form, with identifying details changed and the numbers kept real in shape. It is general information only and not financial, tax, or legal advice; your own numbers should be built on your own accounts. Sydney Virtual CFO engagements are led by a Chartered Accountant (CA ANZ).

How to read this letter as an operator

Founder letters are patterns, not case studies with clients named. The useful move is to steal the diagnostic: which single number would change your next hire, price, or raise timing if you knew it cleanly? If you cannot name that number in one sentence, your reporting is probably ambient rather than decisive. Ambient reporting is how boards get thick and decisions stay late. If you want the artefact without the retainer theatre, the 90-Day Number exists to produce one tool you can run, at a fixed $17,850 plus GST.

Pricing and fit, stated plainly

Sydney Virtual CFO’s front-door product is the 90-Day Number: one named deliverable in ninety days for $17,850 plus GST, typically paid as three instalments of $5,950. That is deliberately different from the common Australian virtual CFO retainer band often quoted around $3,000-$8,000+ per month open-ended. Project pricing fits founders who need a finished cashflow, model, unit-economics build or board pack they can run, not an indefinite meeting cadence. If you need ongoing fractional CFO after day 90, that is a separate, scoped decision, not an automatic rollover. If you only need bookkeeping, this is the wrong product; keep a bookkeeper and use virtual CFO work for decisions on top of clean actuals.

FAQ

Is this a client case study?
No. Founder letters are pattern pieces: real arithmetic shapes with anonymised context. They are written so operators can steal the diagnostic, not so a client can be identified.

What should I do if this number is the one I cannot see in my business?
Name the decision it would change (hire, price, raise timing, cost cut), then build the smallest artefact that surfaces the number. That is often a fixed 90-Day Number deliverable rather than a thicker monthly pack.

Does Sydney Virtual CFO publish these as marketing fluff?
They are marketing, and they are also operating notes. If a letter does not change how you look at your own numbers, ignore it. If it does, act on the number, not the prose.
