I was on-site with a new client recently, doing a stock take.
We hadn’t officially started working together, but their year-end was approaching, and we wanted to go and help them with this big task. They'd struggled for a while with confidence around their stock figures. How the system handled it, whether the numbers were accurate, and whether they could trust what they were looking at. It was creating a knot of uncertainty that ran through a significant chunk of their business.
The sooner we can smooth out this process, the better for everyone. So we went and sat alongside them and their team as they counted stock, starting the relationship the way we intend to continue it.
This is just part of what we do as a fractional finance director, and in this blog, I want to get into the nitty-gritty of what else it covers, what it isn't, and who needs one.
"Fractional finance director" is one of those phrases that sounds more complicated than it is, and gets confused with other things fairly regularly.
It isn't a bookkeeper. Bookkeeping is the recording of financial transactions, keeping the records straight, and the accounts reconciled. Essential, but operational.
It isn't a once-a-year accountant. That relationship is built around compliance: tax returns, year-end accounts, and statutory filings. A lot of accountants just look backwards at what's already happened.
It isn't a full-time hire. A fractional finance director works with your business on a part-time or retained basis, giving you senior financial leadership without the overhead of a permanent member of staff.
And it isn't a consultant who parachutes in, writes a report, and disappears. The fractional model is built on continuity, an ongoing relationship with someone who gets to know your business properly over time.
So what IS it then? A fractional finance director, sometimes called a part-time finance director or virtual finance director, sits at the strategic level. They're the person asking what the numbers mean for the business, not just recording what they are.
A fractional finance director is an experienced senior finance professional who works with your business on a retained, part-time basis. You get the strategic financial leadership of a full-time finance director, without the full-time cost or headcount.
You'll also see the terms part-time finance director and virtual finance director used to describe the same thing. They all mean the same: senior financial expertise, available to your business in the way that makes sense for where you are right now.
The role sits at the strategic level. A fractional finance director is focused on understanding the story behind your numbers and helping you use that understanding to make better decisions. It's the layer of support that sits above day-to-day bookkeeping and annual compliance, looking forward at what's coming rather than backwards at what's already happened.
Most of our clients at Corbar build up to fractional finance director support in stages. They start with compliance and tax to get the essentials right, then build reliable financial visibility through bookkeeping, then step up to fractional support when the business is ready for that next level. It's a natural progression, and we help clients move between stages when the time is right.
Every business is different, so the work looks different too. But the things that show up consistently are these.
Management information you can use. Monthly or quarterly reports that tell you what's happening in the business in plain English, what the numbers are saying, what's changed, and what it means for the decisions coming up. Basically, numbers that get explained rather than just filed.
Cash flow forecasting so the business can plan properly. Growing businesses get caught out by cash flow far more often than by profitability. A business can be doing well on paper and still find itself in a tight spot because of invoice timing, a slow-paying client, or a cost that landed earlier than expected. A fractional finance director keeps a proper eye on the cash position throughout the year, so the business owner can plan for hiring, investment and growth with confidence rather than crossed fingers.
Budgeting and performance tracking that keeps the business on course. Setting a budget that's built on what the numbers can support, then tracking performance against it throughout the year, understanding the variances, and adjusting the plan when the business needs to.
Scenario planning. One of the most useful things a fractional finance director does is help a business look at a significant decision from multiple financial angles before committing to it. What happens if prices go up? What does the cash position look like if that contract comes in late? What does bringing on two more members of staff do to the margins? Running those numbers properly before the decision is made means the business owner is choosing between options they can see, rather than making the call on instinct and hoping for the best.
Strategic guidance on profitability, team structure and pricing. The big questions that sit underneath the day-to-day: are the margins where they should be, is the team structured in a way that makes financial sense, and is the pricing accurately reflecting the cost base? These are the conversations that change the trajectory of a business when they happen regularly with someone who knows the numbers properly.
Tax and remuneration planning that aligns with business goals. At this stage, tax planning becomes more strategic. Director remuneration and profit extraction, tax-efficient business structures, growth planning with tax implications in mind. The difference between compliance, making sure everything is filed correctly and on time, and strategic tax planning is significant. The first keeps you straight with HMRC. The second shapes how the business is structured and how the business owner draws their income in a way that's efficient for their situation.

Six months in, twelve months in, two years in, the relationship builds into something that a one-off review or an annual meeting never could.
Someone who has been properly involved in your finances over time knows the history. They remember the decision made last September and what it was based on. They know which clients tend to pay late and when that creates a cash flow wrinkle. They spot a pattern building before the business owner does, because they've been watching the numbers move over time.
The conversations get more useful, too. The context is already there, which means time is spent on the important stuff rather than bringing someone up to speed at the start of every meeting.
The really interesting thing is that there’s a change in how the business owners relate to their own finances when someone is properly involved throughout the year. You become more interested and invested in your numbers and the power of your financial data when making decisions.
A full-time finance director at SME level typically costs between £80,000 and £120,000 in salary. Add employer National Insurance at 15%, pension contributions, and recruitment fees, and the real cost is considerably higher. For a growing business turning over £1m to £3m with a team behind it, that's a substantial commitment, and often more than the business really needs at this stage.
Fractional finance director support gives you the same level of expertise, scaled to what the business requires right now. At Corbar, that starts from £550 per month, with packages that grow as the business does. Full details are on the website at corbar.uk/services/fractional-finance-director.
There's a point in a business's growth when the existing financial support isn't enough, and it tends to arrive stealthily rather than announcing itself.
The fractional finance director service at Corbar is built for limited companies and multi-director businesses that are fast-growing service providers and agencies. In particular, IT and MSP firms, manufacturers and tech businesses preparing to scale or seek investment, and professional services businesses balancing people, projects and profit.
What they tend to have in common is a team behind them, financial complexity, and a gap between the bookkeeping and accounts being done and anyone thinking strategically about what the numbers mean for the next twelve months. The records are tidy and straight, but the bigger financial questions are landing on the business owner's desk with nobody around with the skill and knowledge to help think them through.
Some questions to help determine if this is right for you: Are significant decisions being made without anyone who really knows the business finances in the conversation? Is the business finding out how the year has gone when the accounts arrive, rather than having a clear sense throughout? Is there a gap between the compliance being handled and anyone thinking about what comes next?
If the business has outgrown year-end accounts and basic bookkeeping and is ready for financial support that looks forward rather than back, fractional finance director support is probably the right next step.
If you're not quite there yet, that's fine too. A good compliance and bookkeeping foundation is the right place to start, and we can help with that as well.
