Hiring a part time finance director is one of those decisions that tends to sit on the back burner until something forces it to the surface: a cash-flow crisis, a missed tax deadline, a bank asking for projections you don’t have. At AVMK Accountants, we work with owner-managed businesses across the UK that are turning over £1m to £10m and wrestling with exactly this question. The good news is that you don’t need a full-time, six-figure hire to get proper financial leadership in your business. Below, we’ll show you exactly what a part-time finance director does, when you actually need one, and how to find the right fit.
A part time finance director is a senior finance professional who provides strategic financial leadership to your business on a reduced-hours or project basis. Unlike a bookkeeper or management accountant, their job is not to process transactions. It’s to interpret the numbers, challenge your assumptions, and help you make better commercial decisions.
In practice, this means owning the financial strategy of the business. A good part time FD will set the framework for your budgets and forecasts, present meaningful management accounts to you each month, manage relationships with your bank and investors, and flag risks before they become problems. They’ll also work closely with whoever handles your day-to-day finance function, whether that’s an in-house bookkeeper or an outsourced team.
What they are not is a replacement for your accountant or bookkeeper. The FD sits above the transactional layer. Think of it as the difference between someone who produces the numbers and someone who tells you what to do about them.
Key responsibilities typically include:
The part time model works because most growing businesses don’t need 40 hours a week of FD-level thinking. They need it consistently, at the right moments.
Most business owners use these titles interchangeably. They shouldn’t. The finance director vs financial controller distinction is one of the most misunderstood in owner-managed businesses, and getting it wrong leads to hiring the wrong person for the wrong problem.
A Financial Controller is operationally focused. Their priority is accuracy, process, and control. They make sure the books are right, the VAT returns go in on time, the payroll runs correctly, and the management accounts are produced to a consistent standard. It’s an essential role, and in many businesses with turnover under £5m, it’s the role that delivers the most immediate value.
A Finance Director operates at a higher level. Their focus is strategic: where is the business going, what does it need financially to get there, and what risks stand in the way? They spend less time in the detail and more time advising the board or the owner.
The practical implication: if your core problem is that your books are disorganised, your VAT is late, and you don’t have reliable monthly numbers, you need a Financial Controller first. If your books are in good shape but you’re struggling to plan ahead, raise finance, or understand what’s driving your profitability, that’s when an FD adds the most value.
Many businesses at the £1m to £5m turnover stage benefit from a hybrid: someone who can do both. That’s precisely the model we operate at AVMK Accountants through our Virtual Finance Function.
Most business owners wait too long. The typical trigger is a crisis: a bank asking for projections, a cash shortfall that comes out of nowhere, or a year-end tax bill that’s far larger than expected. By that point, you’re managing the problem rather than preventing it.

The signals that suggest you’re ready for part time finance director support tend to be subtler. According to ICAEW guidance on financial leadership for SMEs, businesses that invest in senior finance leadership earlier in their growth cycle tend to make better capital allocation decisions and experience fewer cash-flow shocks.
Watch for these indicators in your own business:
Any one of these is worth acting on. Two or more together, and the case for hiring becomes hard to ignore.
The fractional model is not a compromise. For most businesses under £10m turnover, it’s a better arrangement than a full-time hire.
A fractional finance director brings the same level of expertise as a full-time FD but works across a number of businesses simultaneously. This keeps the engagement commercially viable for both parties. You get senior-level thinking without the full-time employment cost, and the FD maintains a breadth of experience across sectors that a single-company hire rarely develops.
The fractional finance director benefits that matter most to owner-managed businesses are:
The one limitation worth acknowledging: a fractional FD will never be as embedded in the day-to-day as a full-time hire. If your business is at a stage where you need someone present in the office every day, managing a large finance team, the fractional model may not be sufficient.
Cash-flow forecasting is one of the clearest tests of whether a finance director is actually adding value. It’s also one of the areas where most growing businesses are weakest.
A well-run cash-flow forecast is not a spreadsheet updated once a quarter. It’s a rolling, 13-week view of cash inflows and outflows that gets reviewed and updated every week. As the Chartered Institute of Management Accountants guidance on cash management makes clear, short-term cash visibility is a prerequisite for sound financial decision-making in any business.
Your part time FD should own the following as non-negotiables:
The practical value of this is significant. Knowing three months in advance that you’ll hit a cash pinch point gives you options: you can accelerate collections, delay non-essential spend, draw on a facility, or renegotiate payment terms with a supplier. Finding out the week it happens gives you none of those options.
The hiring process for a part time finance director is different from a standard recruitment exercise. You’re not just assessing technical competence. You’re assessing whether this person can communicate clearly with a non-finance audience, challenge your thinking constructively, and build trust quickly.

As Companies House guidance on director responsibilities notes, a finance director carries legal and fiduciary responsibilities. That means the person you bring in needs to be commercially experienced, not just technically qualified.
Practical things to look for:
The core difference is control versus flexibility. An in-house part-time hire works exclusively for you on a reduced-hours contract. An outsourced fractional FD works across several clients and is typically engaged through a firm or on a consultancy basis.
| Factor | In-House Part-Time | Outsourced Fractional |
|---|---|---|
| Exclusivity | Works for you only | Works across multiple clients |
| Cost structure | PAYE salary + employer NI | Fee-based, no employment costs |
| Flexibility | Harder to scale up or down | Easier to adjust scope |
| Embedded knowledge | Builds over time | Strong from day one |
| Recruitment risk | Higher | Lower |
| Best for | Businesses needing regular presence | Businesses needing strategic input |
For most owner-managed businesses under £5m turnover, the outsourced fractional model offers better value and lower risk. Above £5m, the calculus starts to shift depending on complexity and the volume of work involved.
Before signing any engagement letter, get clear answers to these:
The last question is the most revealing. A finance director who can’t show you a clear, well-presented example of their work is unlikely to produce one for your business.
Most owner-managed businesses reach a point where good bookkeeping and year-end accounts are no longer enough. The numbers exist, but nobody is using them to drive decisions. At AVMK Accountants, our Virtual Finance Function and Fractional Financial Controller service are built for exactly this stage: businesses that need Financial Controller-level oversight, management accounts, and cash-flow forecasting delivered consistently each month, without the cost and commitment of a full-time hire.

A financial controller focuses on the accuracy and organisation of your financial records: bookkeeping, management accounts, VAT, payroll and reporting. A finance director operates at a higher strategic level, advising on business direction, funding, acquisitions and long-term financial planning. Many growing businesses at the £1m-£10m turnover stage need elements of both, which is why a fractional arrangement that combines controller-level rigour with FD-level insight often works well in practice.
There is no fixed turnover threshold, but businesses typically start feeling the need for finance director input somewhere between £1m and £5m. The real trigger is complexity rather than size alone: multiple revenue streams, tighter margins, a growing headcount, or plans to raise finance or acquire another business. If your current accountant only contacts you at year-end and you are making significant decisions without reliable monthly numbers, that is a clearer signal than any revenue figure.
Fees vary depending on the scope of work, the seniority of the individual, and how many days per month are involved. A fractional or part-time arrangement is almost always significantly more cost-effective than a full-time hire, which carries salary, employer National Insurance, pension contributions and benefits on top. For current pricing relevant to your business, it is worth speaking directly with the provider to understand what is included and how the engagement would be structured.
Outsourcing your finance function gives you access to senior financial expertise without the overhead of a full-time hire. You get consistent monthly reporting, proactive tax and cash-flow management, and a finance professional who is focused on your numbers rather than reactive compliance. For owner-managed businesses, it also removes the risk of over-reliance on a single internal employee, and means your finance capability scales with your business rather than being fixed to a headcount decision made years ago.
