Fractional Financial Controller: What It Is and Who It's For

A fractional financial controller is a qualified finance professional who works with your business on a part-time or retained basis rather than as a full-time employee. You get the same level of expertise and the same scope of work, but at a cost that reflects the time your business actually needs.

The model has become common for a simple reason. Most businesses between £1 million and £5 million turnover need financial controller-level support, but they don't generate enough work to justify someone full-time.

What they do

A fractional financial controller handles the same responsibilities as an in-house one. The bookkeeping and transaction management that keeps your financial data accurate. The production of management accounts that show you how the business is performing. VAT returns, payroll, and compliance work that has to be done properly and on time. Cash flow forecasting that gives you visibility of what's coming. And the advisory work that turns financial data into better business decisions.

The difference is in how the work is delivered. Rather than sitting in your office five days a week, a fractional financial controller works remotely with access to your systems, and meets with you regularly to go through the numbers and discuss what needs attention.

Why not just use a bookkeeper and an accountant?

A bookkeeper records your transactions. An accountant files your returns. Between them, they handle the compliance side of your finances.

What neither of them typically provides is the bit that actually helps you run the business. The management information that tells you which services are profitable and which aren't. The forecasting that shows you what your cash position looks like in three months. The analysis that helps you make pricing decisions, hiring decisions, and investment decisions based on data rather than gut feel.

A fractional financial controller fills that gap. They sit between the bookkeeper and the traditional accountant, turning accurate data into useful information that helps you make better decisions.

How the cost compares

A full-time finance director costs roughly £75,000 to £80,000 per year when you add NI, pension, and overheads to the salary. That's around £6,500 per month.

A fractional financial controller costs a fraction of that, typically because you're paying for the time your business actually needs rather than a full-time salary. For most of my clients, the monthly fee is significantly less than a full-time hire and they're getting everything they need.

The other cost saving that's easy to overlook is risk. If a full-time hire doesn't work out, the recruitment cost, notice period, and replacement process can easily add up to £20,000 to £30,000. With a fractional arrangement, if it doesn't work, you walk away without that burden.

How to know if you need one

There are a few common signs. You're making business decisions based on your bank balance rather than proper financial data. Tax bills keep surprising you. You can't tell which parts of your business are most profitable. You're spending your own time on financial admin when you should be focusing on revenue. Or you've got a bookkeeper who's doing a good job with the transactions but nobody is turning that data into information you can use.

If two or more of those apply, you've probably outgrown your current setup.

I work as a fractional financial controller for businesses across several sectors. If you'd like to know what that would look like for your business, take a look at how I work or get in touch.
