Do You Need a Fractional Finance Manager? A Practical Guide for Growing SMEs
Not every business needs a CFO. Not every business needs a financial controller. Sometimes what a growing SME needs most is someone who can simply take ownership of the day-to-day finance function — keep the numbers moving, the processes running, and the operational side of money well managed — without the cost or commitment of a full-time hire.
That's what a fractional finance manager does. And for many businesses in the £1–10m revenue range, it's the most practical and cost-effective first step toward getting proper financial management in place.
What a Fractional Finance Manager Actually Does
A fractional finance manager handles the operational engine room of your business's finances. They're the person who makes sure the financial basics are done properly, consistently, and on time — so that the rest of the business can run without the founder or MD constantly firefighting financial admin. In a typical SME engagement, a fractional finance manager will cover the following areas.
Accounts payable and receivable
Making sure invoices go out on time, suppliers get paid according to terms, and cash is collected efficiently. For many SMEs, this alone transforms cash flow — simply because no one has been owning the process properly.
Bank reconciliations and bookkeeping oversight.
Whether the business does its own bookkeeping or outsources it, the finance manager ensures the records are accurate and reconciled. They catch errors, chase discrepancies, and make sure the data feeding into your accounts is clean.
Payroll management
Overseeing payroll — whether it's run internally or through a bureau — ensuring employees are paid correctly and HMRC submissions are handled. For growing SMEs taking on staff quickly, having someone who owns this process is essential.
Monthly management reporting
Producing basic management reports that give the leadership team visibility over revenue, costs, cash position, and key financial metrics. This isn't the deep strategic analysis a CFO would provide — it's the accurate, timely financial snapshot that most SMEs are missing entirely.
Budget tracking
Helping departments understand and track their spend against budget, flagging variances, and providing the financial visibility that allows the business to make informed decisions rather than guessing.
Liaison with external accountants and auditors
Your finance manager becomes the first point of contact for your external accountant, handling information requests, preparing year-end packs, and coordinating the audit process if applicable. This takes a huge administrative burden off the founder or MD.
How This Differs from a Bookkeeper
Many SME owners think they already have this covered because they have a bookkeeper. But a bookkeeper and a finance manager are different roles with different scopes. A bookkeeper records transactions. They process invoices, code entries, and produce the raw data. They're essential — but they're typically not managing the finance function. They're doing the data entry, not overseeing whether the processes are working or the outputs are reliable.
A finance manager sits above the bookkeeper. They own the processes, review the outputs, manage the workflow, and take responsibility for the quality and timeliness of the financial information flowing through the business. They're the person who ensures the bookkeeper's work is correct, that nothing falls through the cracks, and that the leadership team gets the financial information they need to run the business.
If you have a bookkeeper but no one checking their work, managing the overall finance function, or producing meaningful management information — that's the gap a fractional finance manager fills.
How This Differs from a Financial Controller or CFO
The hierarchy in a finance function typically runs: finance manager → financial controller → CFO. Each level adds a layer of seniority, strategic focus, and cost.
A fractional financial controller focuses on the accuracy and integrity of your financial data — management accounts, controls, compliance, and financial reporting. They own the numbers. A fractional CFO focuses on strategy — financial planning, fundraising, commercial decision-making, and board-level reporting. They use the numbers to drive the business forward.
A fractional finance manager focuses on operations — keeping the day-to-day finance function running smoothly, accurately, and on time. They produce the numbers.
For many SMEs, the right starting point is a finance manager. Once the operational finance is running well, you can layer in a financial controller for rigour and reporting quality, and a CFO for strategic direction. Some businesses need all three (at different levels of commitment). Others only need one. The right answer depends on where the business is and what's currently broken.
Signs You Need a Fractional Finance Manager
You probably need a fractional finance manager if you recognise any of the following:
You're the founder or MD and you're still doing (or closely overseeing) the financial admin yourself. You have a bookkeeper but no one managing them or checking their work. Invoices go out late, payments come in late, and cash flow feels chaotic even though the business is busy. You don't have clear monthly financial reports — or the ones you get don't feel reliable. Payroll, VAT returns, or supplier payments have had errors recently. You're spending time on financial admin that should be spent on growing the business. Your external accountant keeps asking for information you don't have readily available.
The common thread is operational financial pain. The business is growing, but the finance function hasn't grown with it. A fractional finance manager closes that gap without the cost of a full-time hire.
What does a fractional finance managercost?
A fractional finance manager is the most cost-effective level of fractional finance support. For most SMEs, 1–3 days per week is sufficient to transform the operational finance function. A full-time finance manager would cost £35,000–£50,000 in salary plus employer costs. A fractional model gives you access to experienced finance professionals at a lower total cost, with the flexibility to adjust the days as the business needs change.
For businesses at the earlier end of the revenue scale — say £1–3m — this is often the first and only fractional finance hire they need. As the business grows, they might add FC or CFO support on top, but the finance manager remains the operational backbone.
A Common Starting Point
Many of the businesses we work with at The Finance People start with a fractional finance manager. It's the quickest way to take financial admin off the founder's plate, get reliable numbers flowing, and create the foundation that more senior finance support can build on later.
Some clients eventually step up to a fractional CFO as the business scales and the strategic questions become more complex. Others find that a finance manager, combined with a good external accountant, gives them everything they need. We help you work out the right path — and we never recommend more than what's actually needed.
If you're spending too much of your time on financial admin, or if your bookkeeper is working unsupervised and you're not sure the numbers are right, a fractional finance manager might be exactly what your business needs right now.
