What is a fractional FD, and when does a growing business need one?

"I don't know if I can afford to grow."

When an owner says that, it usually isn't really a question about money. It's a question about information. They can see the bank balance and last year's accounts, but nobody is sitting beside them showing what the next twelve months could look like, what growth would cost, and whether the business can carry it.

In a large company, that's the finance director's job. Most owner-managed businesses don't need, and can't justify, a full-time FD. But they still need the thinking. That's the gap a fractional FD fills.

What a fractional FD is

A fractional FD (sometimes called a part-time, outsourced or virtual FD) is an experienced finance director who works with your business for a set number of hours or days a month, rather than full time.

You get the same kind of senior finance thinking a larger business would have in-house, scaled to what you need and what you can sensibly spend. It's usually an ongoing relationship, typically with a regular monthly meeting, rather than a one-off project.

What they actually do

The work varies from business to business, but it tends to fall into four areas.

1. Turning your numbers into decisions. Making sure you get timely monthly figures, and more importantly, helping you understand what they're telling you. Which customers and services really make money, where margin is leaking, and what needs to change.

2. Planning ahead. Building a budget and a cash flow forecast, so you can see the effect of a decision before you make it: a new hire, a price rise, a second site, a large contract.

3. Managing cash. Keeping an eye on how long your money is tied up, when the big tax bills land, and whether you're holding enough in reserve. (Our guide to building a 13-week cash flow forecast shows the kind of tool involved.)

4. Being a sounding board. Often the most valuable part. An experienced person to think out loud with, challenge assumptions, sit in on bank or investor meetings, and make sure the things you agreed actually get done.

How a fractional FD differs from your accountant

Your accountant and a fractional FD look at the same numbers, but they're doing different jobs.

Neither replaces the other. Compliance work has to be done properly, and it's the foundation everything else is built on. But a business that only ever looks backwards is driving by the rear-view mirror.

Some firms, including ours, do both, which has the advantage that the person planning your future already knows your figures inside out.

Fractional, full-time, or neither?

For most businesses below a certain size, a full-time FD would spend much of their week on work that doesn't need someone that senior. Fractional support means paying for the thinking, not the hours in between.

There's also a middle step for businesses that aren't sure yet: a one-off diagnostic that looks at where things stand today, before committing to anything ongoing.

Eight signs it might be time

None of these on its own means you need an FD. But if three or four sound familiar, it's probably worth a conversation.

1. You're profitable on paper but cash always feels tight. (We explain why that happens in why profitable businesses still run out of cash.)
2. You're making big decisions on gut feel, such as hiring, pricing or investing, without seeing the numbers first.
3. Your figures arrive too late to act on. If you see last month's results six weeks after the month end, they're history, not information.
4. You're growing quickly and aren't sure the business can fund it.
5. You're about to borrow, raise money or talk to a buyer, and need numbers that will stand up to scrutiny.
6. Margins are slipping and you can't say exactly why.
7. You've outgrown the way the finances are run: spreadsheets everywhere, nobody quite sure which figure is right.
8. You want to step back, sell, or hand the business on in a few years, and need a plan that works backwards from that.

What it typically costs

Fees vary widely depending on how much time is involved, how complex the business is, and whether the arrangement is a fixed monthly retainer or a day rate. Rather than quote a "market rate" that may not reflect your situation, the more useful question is this: what is the improvement worth?

A good fractional FD should be able to point to where the value will come from, whether that's better margins, faster cash collection, avoided mistakes, or a stronger position with a lender or buyer. And the relationship should be judged against it. If the value isn't clearly bigger than the fee, it isn't the right fit yet.

How to choose one

• Relevant experience. Have they sat in the finance chair of a business like yours? Sector knowledge shortens the learning curve considerably.
• Professional qualification and regulation. Check they're a member of a recognised body, such as ACCA, ICAEW or CIMA, and covered by professional indemnity insurance.
• A clear structure. You should know what happens each month, what you'll receive, and how progress will be measured.
• A clear exit. Look for a sensible review point and notice period, rather than a long lock-in.
• Chemistry. You'll be discussing the most important decisions in your business. You need to trust them, and they need to be willing to tell you things you'd rather not hear.

How we approach it

We work with a small number of established businesses through a structured fractional FD service called C.A.L.M.S: Clarity, Alignment, Leverage, Momentum and Support. It's built on my own years as an industry finance director, including in hospitality, leisure, education and marketing businesses, and it's designed to do one thing: help owners understand their numbers well enough to make better decisions, then make sure those decisions actually happen.

Every engagement starts the same way, with Clarity: a six-week financial health check that looks at your key numbers, your cash and how you compare with businesses like yours. You leave with a written plan whether or not you go any further, so you can judge for yourself whether ongoing FD support is worth it.
