We had a good accountant for eleven years. Returns filed early, VAT never wrong, tax planned properly, calls returned the same day. I want to be clear about that, because the story that follows is not a story about a bad accountant. It is a story about assuming that one job was the same as another job, and losing three years to the assumption.
The difference nobody explains when you start out
Compliance accounting answers the question "what happened". It looks backwards, to a statutory deadline, in a format designed for Companies House and HMRC rather than for you. Done well, it is precise, timely and genuinely valuable.
The other job answers "what should we do next". Which work makes money and which only looks like it does. What the next thirteen weeks of cash actually look like. Whether the price list still reflects what delivery costs. Whether the biggest client is the best client.
Most owners assume the second comes free with the first. It does not, and no accountant is doing it inside a fixed compliance fee — not because they can't, but because nobody asked them to and nobody is paying for it.
Compliance accounting tells you what happened. Nobody was doing the job that tells you what to do next, and we had quietly assumed it came free with the first one.
What it looked like from the inside
Turnover went up for three years running. The bank balance did not. That pattern has a name and we now have a whole file on it — it is the difference between cash flow and profit, and it shows up as the strange, hollow feeling described in how a record year can leave you with less money.
The symptoms were all small enough to explain away individually. We were quoting from a rate card built two years earlier. We took on work every October that we regretted every January. The VAT bill arrived as a surprise every single quarter, which after eleven years is not really a surprise, it is a decision not to look. And if you had asked me which of our clients made money, I would have named the biggest one, confidently, and I would have been wrong.
Two days a month
What we eventually bought was two days a month from a fractional finance director. Not a hire — no National Insurance, no pension, no notice period, no office chair. A contract for a defined output.
The first ninety days produced four things. A thirteen-week cash flow forecast, updated weekly, which meant the VAT quarter stopped being an event. Gross margin by job, which is where the real damage was hiding. A debtor list with a named person against every line, which turned chasing from a mood into a task. And a single page of five numbers reviewed on the first Monday of the month — much the same discipline described in five numbers every UK business owner should know cold and how to read your management accounts in fifteen minutes.
The report that made the whole case in one morning
Here is the shape of the analysis, with figures rounded for illustration. Five clients, one year, revenue against the direct cost of delivering it.
Client A billed £180,000 and cost £151,000 to deliver — £29,000 of gross profit, a 16% margin. Client B billed £96,000 against £58,000, so £38,000 at 40%. Client C billed £74,000 against £41,000: £33,000 at 45%. Client D billed £52,000 against £47,000, leaving £5,000 at 10%. Client E billed £38,000 against £19,000 — £19,000 at 50%.
Total revenue £440,000, total gross profit £124,000, an overall margin of 28%.
Read it once and the problem is obvious. Our largest client by revenue generated less gross profit than one a third of its size, while absorbing our two most senior people almost full-time. Client D was a rounding error that felt like a real account because the invoices were large. The two genuinely profitable relationships were the two we spent the least time thinking about.
None of that required clever accounting. It required somebody to allocate delivery hours to jobs and divide. It took a morning. We had not done it in eleven years because it was nobody's job, and it was nobody's job because we had never separated the two roles in our heads.
What followed was unglamorous: we repriced A at renewal, exited D at the end of its term, and moved capacity onto C and E.
How to work out whether it is worth it
A fractional FD quotes a day rate and you agree the days and the scope. Do the arithmetic in the direction that matters. Two days a month at £700 a day is £16,800 a year. Repricing one client by 8% on £180,000 of revenue puts £14,400 of gross profit back in a single year, and that was one of four decisions the first quarter produced.
But the real test is not affordability. It is this: name three decisions you made in the last twelve months that you would have made differently with better numbers in front of you. If you can name three quickly, you are already paying for the absence of this role. If you genuinely cannot, you do not need one yet — go and build the margin-by-job report yourself first, because it is a morning's work and it will tell you whether there is anything to find.
What it did not fix
It did not win us any work. It did not make the hard conversations easier — it made them unavoidable, which is a different thing and, in the moment, a worse-feeling one.
And the first two months were genuinely uncomfortable, because the reports said things about my judgement that I had been carefully not looking at for three years. The client I had been proudest of winning was the one dragging the margin down. That is not a pleasant sentence to have handed to you in a spreadsheet by someone you are paying.
What I would tell myself three years earlier
The trigger is not a turnover figure. Every version of this advice picks a threshold and every threshold is wrong for somebody. The real trigger is the moment you cannot answer "which of these jobs makes money" without giving up a weekend to a spreadsheet — and the moment after that, when you stop asking the question because you already know the weekend it would cost.
We reached that point three years before we did anything about it. The accountant was never the gap. The gap was that we only ever bought one of the two jobs, and never noticed there was a second one.
Common questions
What does a part-time finance director do that an accountant doesn't?
An accountant's core job is compliance: statutory accounts, corporation tax, VAT and payroll, prepared accurately and filed on time. It is backward-looking by design, because that is what the deadlines require. A finance director's job is forward-looking — a rolling cash forecast, margin analysis by job or client, pricing decisions, funding conversations, and the monthly discipline of comparing what happened against what you expected. The two overlap in the source data and almost nowhere else. Plenty of accountancy firms offer both, but the second is a separate engagement with a separate fee, and assuming it arrives inside a fixed compliance quote is how most owners end up without it.
How much does a fractional finance director cost?
They quote a day rate and you agree how many days a month and what those days produce, so the honest answer is that it depends entirely on scope and seniority — ask three for a written proposal rather than working from a figure in an article. What matters more is testing the number against the decisions it changes. If two days a month comes to £16,800 a year, ask what a single well-informed repricing, one exited loss-making client, or one avoided borrowing decision would be worth over the same year. If you cannot construct that case from your own numbers, the engagement is probably premature.
At what size does a business actually need one?
Not at a turnover figure — every threshold anyone quotes is wrong for somebody. The useful test is behavioural. Can you answer "which of our jobs or clients makes money" without a weekend of spreadsheet work? Do you know what the next thirteen weeks of cash look like? Has your price list been reviewed against actual delivery costs in the last year? If the answer to any of those is no, the role is already missing, whether turnover is £300,000 or £3m. Build the margin-by-job report yourself first. It takes a morning, and it will tell you plainly whether there is enough to find to justify paying somebody.
Could our existing accountant just do this instead?
Often yes, and it is usually the first call to make. Many firms offer management accounts, forecasting and advisory work as a separate service, and your accountant already has the data and the history. The reason it does not happen by default is that nobody asked and nobody is paying for it. Be specific about what you want produced and how often — a thirteen-week cash forecast, gross margin by client, a monthly review meeting — rather than asking for more advice in general terms, which produces nothing anyone can price. If they cannot commit to a scope and a date, that is a clear answer, and a fractional finance director is the alternative.
