Do You Need a Finance Director, or Just Better Numbers?

The short answer: a director, or better numbers?

If you are asking whether you need a finance director, you have usually hit the point where your accounts feel too important to run on gut and a spreadsheet, but not important enough to justify a 120,000 pound hire. The honest answer for most owners under about 3m pounds of turnover is that you do not need a finance director yet. You need a finance function that produces reliable monthly numbers, and FD level judgement brought in only when there is a financing, acquisition or exit decision to steer. An FD hired on top of messy books ends up doing bookkeeping at FD rates, which is the most expensive way to tidy a ledger anyone has invented.

The word "fractional" has made the decision look simpler than it is. A fractional finance director, an experienced FD working with you a few days a month, is a genuinely good answer to one problem: you need senior finance thinking and cannot justify a full time salary. It is not an answer to a different and more common problem: your monthly figures arrive late, or you do not trust them. Those are two separate gaps, and buying the wrong fix for yours is how owners end up paying for strategy while the basics stay broken. The monthly numbers come from your management accounts, and until those are solid, no director can steer on them.

What a finance director does that your accountant does not

An accountant and a finance director are not the same job, and the confusion costs owners real money. Your accountant looks backwards and keeps you compliant: year end accounts, the corporation tax return, VAT, payroll, Companies House. A finance director looks forwards and steers: cash flow forecasting, pricing and margin, funding and covenants, the numbers behind a sale or an acquisition, and the monthly management pack that tells you what is actually happening while you can still do something about it.

The gap between those two is where most growing businesses quietly lose money. You can be fully compliant, every return filed on time, and still have no idea which jobs make money, when cash gets tight, or whether the bank covenant you signed is about to bite. That forward view is what a director brings, and it only works when it sits on top of reliable management accounts produced every month without fail. The director reads the dials. Someone still has to build them.

This is the distinction the fractional model blurs. A fractional FD will happily read your dials and tell you what they mean, but they are not there to build them from a shoebox of receipts, and you would not want to pay their rate for it if they were.

What a full time finance director actually costs

A full time finance director is a big number, and the salary is only the start of it. An experienced FD for a business turning over 1m to 5m pounds commands a base salary of roughly 95,000 pounds, far above the UK median full time salary of 39,039 pounds recorded by the ONS for April 2025. On top of the salary sit the costs every employer carries, and they are heavier than they used to be.

For the 2026 to 2027 tax year, employer National Insurance runs at 15 percent on everything an employee earns above the 5,000 pound secondary threshold, which on a 95,000 pound salary adds about 13,500 pounds. Auto enrolment pension is at least 3 percent of qualifying earnings as the employer minimum, and most FD packages carry benefits well beyond that, so pension and benefits together land around 11,300 pounds on a conservative view. Add it up and a full time FD costs close to 120,000 pounds a year before you have paid a recruiter to find them.

Two things soften that number a little, and neither changes the conclusion. The salary is an allowable cost, so it reduces taxable profit, and at the 25 percent corporation tax main rate roughly a quarter of it comes back as lower tax. And the 10,500 pound Employment Allowance exists to cut employer National Insurance. In practice the allowance is usually already absorbed by your existing payroll, so it rarely touches the FD's own National Insurance. Even after the tax relief, you are committing well over 80,000 pounds of real cash a year to a single hire, on an open ended contract, for a business that may only need senior finance input a few days a month. That mismatch is exactly what the fractional and managed options exist to solve.

What a fractional finance director is, and where it stops

A fractional finance director is an experienced FD who works across several businesses, giving each one a day or two a month rather than a full time commitment. You get genuine senior judgement, on cash, funding, margin and the bigger decisions, for somewhere around 24,000 pounds a year rather than 120,000 pounds, and you can scale the days up around a funding round or a sale and back down afterwards. For a business with a real strategic question and clean numbers already in place, it is an excellent answer.

Here is where it stops, and it is the part the glossy version leaves out. A fractional FD reviews and advises. They do not run your bookkeeping, reconcile your bank, produce your management accounts or run your payroll, because that is not what a day or two of senior time a month is for. So if you bring one in while your underlying finance function is weak, one of two things happens: either they spend their expensive days patching the basics instead of steering, or they advise confidently on numbers that are not reliable, which is worse. A fractional FD is the roof. You still need the walls.

The option most owners actually need: a managed finance function

For most owner managed businesses, the right answer is neither a full time FD nor a fractional one working on shaky foundations. It is a managed finance function: the whole finance operation run for you for a fixed monthly fee, the bookkeeping, the monthly management accounts, payroll and controls, with senior review on top and FD level input available when a bigger decision lands. It is the walls and the roof together, from one engagement.

The cost comparison is what makes owners stop and reread. A managed finance function for a growing owner managed company runs from roughly 18,000 to 30,000 pounds a year, broadly the same as a couple of fractional FD days a month, and for that you get the entire finance operation rather than senior input alone. Set the three options side by side and the trade off is clear.

The point of the chart is not that two of the bars are the same height. It is what each one buys. The full time FD gives you senior finance all day, every day, at a cost that only makes sense once the business is large or complex enough to keep them busy. The fractional FD gives you senior input a few days a month and nothing underneath. The managed function gives you the numbers produced, the controls run and senior review, for about the same outlay as the fractional option. For a business that mainly needs to trust its monthly figures and get a steer on the occasional big decision, that is usually the best value of the three.

How to decide: do you need a finance director yet?

Two questions settle it for most owners. First, do your monthly management accounts arrive on time and do you trust the numbers in them? If not, that is the gap, and no director fixes it, a reliable finance function does, so start there. Second, if your numbers are solid, is there a financing, acquisition or exit decision to steer in the next year or two? If there is not, a managed finance function with senior review is almost always enough. If there is, that is when FD level input, fractional or built into a managed function, earns its keep.

There is one caveat worth naming, because it overrides the whole framework. If a lender or an investor is already asking you for FD level reporting, forecasts signed off by a finance professional, a detailed funding model, board grade management accounts, then the timing is theirs, not yours. You bring in FD level input because the money requires it, whatever stage you think you are at. Short of that external pressure, the rule holds: get the numbers reliable first, add senior steering when a real decision arrives.

What this means for you: what to do next

Start by being honest about which gap you actually have. If your monthly numbers are late or you do not fully trust them, the first job is a finance function that produces reliable management accounts, not a director to interpret figures that are not sound. If your numbers are solid and a funding round, a purchase or a sale is on the horizon, that is the moment FD level input pays for itself. And if a lender or investor is already asking for it, the decision is made for you.

For most owner managed businesses under about 3m pounds of turnover, the practical answer is a managed finance function that runs the numbers every month and brings in FD level steering when a real decision lands, rather than a 120,000 pound hire the business cannot yet keep busy. That is the structure that gives you numbers you trust now and senior judgement exactly when you need it, without the open ended salary. If you want a straight read on which of the three fits your business, that is a short conversation, and it is worth having before you commit to a hire that runs for years.
