“Fractional FD” is one of those terms that gets thrown around without being explained, which makes it harder to know whether you actually need one. So let me clear it up properly.
This is what a fractional or outsourced Finance Director actually does, when a business is ready for one, and what the role looks like in practice.
What is a fractional FD?
A fractional FD (also called an outsourced FD or part-time FD) is a senior finance professional who works with your business on a part-time or as-needed basis, rather than as a full-time employee.
You get the strategic finance input that a full-time Finance Director would bring, without the £80,000+ salary, pension, NI, and on-costs that come with a permanent hire. For growing SMEs in the £1m to £5m range, this is often the most leverage you can buy with your finance budget.
What a fractional FD is not
Worth being clear on this, because the terminology gets muddled. A fractional FD is not:
- A bookkeeper. A bookkeeper records what’s already happened. A fractional FD interprets it and helps you decide what to do next.
- A management accountant only. Producing monthly management accounts is one part of the job, but the strategic input is the bigger part.
- An accountant doing your year-end. Your accountancy firm files your statutory accounts and tax. A fractional FD works with your business through the year on its actual financial direction.
They sit at a different layer. Bookkeeper records. Accountant complies. Fractional FD plans.
What a fractional FD actually does
The work varies by business, but typically includes:
- Cashflow forecasting and management. A proper rolling cashflow forecast, updated regularly, so you see the squeeze coming before it lands.
- Monthly management reporting. Real numbers, properly explained, so the board (or you) can actually make decisions on them.
- Budgeting and planning. Annual budgets that mean something, broken down by month, with realistic targets and trigger points.
- Profitability analysis. Which clients, products or services are actually making money? Which are quietly costing you? Most growing businesses don’t really know, and they should.
- KPI design and tracking. The numbers that actually matter for your specific business, watched properly month-on-month.
- Funding and investment support. Whether that’s preparing a financial pack for a bank, supporting a fundraising round, or just helping you understand whether borrowing makes sense.
- Strategic input on big decisions. Hiring, pricing changes, new product launches, acquisitions. The kinds of decisions where you want a financial brain in the room before you commit.
None of this is the bookkeeper’s job, and a year-end accountant rarely has the time or the relationship to do it justice. That’s exactly the gap a fractional FD fills.
When is a business ready for one?
There’s a moment in growing a business when the bookkeeper isn’t enough anymore, but a full-time Finance Director is too much. Both ends of the spectrum, with very little useful middle ground. That’s the moment.
Practically, that usually means:
- Turnover somewhere between £1m and £5m, though it can be relevant outside that range.
- Growth that’s complicating the financial picture (multiple revenue streams, increasing headcount, more moving parts than a single owner can hold in their head).
- Decisions on the horizon (hiring senior people, raising capital, taking on bigger contracts, acquisitions) where you’d benefit from senior finance input.
- A genuine sense that you’re flying slightly blind on the numbers and would make better decisions with a clearer view.
If none of those sound familiar, you probably don’t need a fractional FD yet. A good accountant doing proper management accounts may be enough. If most of them do, the conversation’s worth having.
How does the engagement usually work?
There’s no single model, but typical engagements involve a fixed monthly fee for an agreed scope of work, often somewhere between a few days a month and a regular weekly presence. You’d usually have a monthly board / leadership meeting where the FD presents the numbers and the strategic recommendations, plus ad-hoc support between meetings for specific decisions.
The cost is typically a fraction of a full-time hire, and a fraction of what some specialist FD agencies charge. The whole point is leverage: senior brain, part-time cost.
Is it worth it?
Honest answer: for a business that’s properly ready, the financial return is usually obvious within the first few months. Spotting the loss-making product line, fixing the cashflow squeeze before it bites, getting the right answer on the hire decision, any one of these typically pays for the engagement many times over.
For a business that’s not yet ready, it’s wasted money. The fractional FD’s value comes from having something meaningful to plan with. If the business is still simple, the answer is probably better bookkeeping and a sharper accountant, not a senior finance hire.
The test is straightforward: are you making real decisions that would benefit from senior finance input, and would seeing the numbers more clearly genuinely change what you do? If yes, you’re ready.
