An outsourced finance director (also called a fractional or virtual FD) gives a growing UK business senior financial leadership on a flexible, part-time basis (typically a few days a month) instead of a full-time salary. Every growing business reaches a point where the numbers get too big to handle alone. At this point, you need someone who can look beyond day-to-day bookkeeping and help you plan, forecast, and make confident decisions. That person is a Finance Director. The question then becomes whether you hire one in-house or bring in an outsourced finance director instead.
This guide compares both options. We look at the costs, the roles, and the practical signs that tell you which route fits your business right now.
What Does an Outsourced Finance Director Do?
An outsourced finance director (sometimes called a fractional or virtual FD) gives you senior financial leadership without a full-time salary. They work with you on a flexible basis, often a few days a month, and they focus on the bigger picture.
Typical work includes cash flow forecasting, budgeting, management reporting, pricing decisions, funding applications, and board-level advice. They take your numbers and turn them into a clear plan you can act on. Think of the outsourced FD as a strategic partner rather than someone processing your invoices.
Outsourced Finance Director vs In-House FD: What’s the Difference?
The core difference is how you access the expertise.
An in-house FD is a permanent employee. They are in your business full time, part of the team, and available every single day.
An outsourced finance director is external. You buy their time and experience as and when you need it. You get the same seniority, but you only pay for the time and work you actually need. For a lot of growing businesses, that flexibility is the deciding factor.
Comparing Costs: Outsourced Finance Director vs Full-Time FD
Cost is usually the first thing owners ask about, so let’s consider that.
A full-time in-house FD in the UK typically costs somewhere between £80,000 and £120,000 in salary. Once you add Employer’s National Insurance, pension contributions, bonuses and benefits, the true cost of employment can often reach £100,000 to £150,000 a year.
An outsourced finance director (or fractional FD) works on a day rate or a monthly retainer. Rates vary, but many growing businesses spend between £1,500 and £4,000 a month depending on how much support they need, or £600 to £1,100 a day for project-based work. That works out at roughly £18,000 to £48,000 a year.
| Outsourced / Fractional FD | In-House FD | |
|---|---|---|
| Typical UK cost | £18,000–£48,000/yr (£1,500–£4,000/month, or £600–£1,100/day) | £100,000–£150,000/yr all-in |
| Availability | A few days a month, flexible | Full time, every day |
| Best suited to | Growing SMEs with periodic senior finance needs | Businesses with daily, high-volume finance decisions |
| Commitment | Short notice period, scalable up/down | Permanent employment contract |
The savings are clear. You get senior input for a fraction of the fixed cost, and you can scale the support up or down as your needs change.
Roles and Responsibilities Compared
Both roles cover similar ground. The difference is depth and availability.
An in-house FD runs the finance function day to day, leads the team and is on hand for every decision. An outsourced finance director focuses on the high-value work such as strategy, forecasting and reporting, then steps back once it is done.
For most businesses under a certain size, the outsourced model covers everything you actually need, without paying for time you would not use.
When Should You Hire an Outsourced Finance Director?
The right time is usually when your business has outgrown basic bookkeeping but cannot yet justify an outsourced FD.
Common triggers include rapid growth, a funding round for expansion, cash flow that feels tight despite healthy sales due to financing growth plans, or a board that wants clearer and more detailed financial reporting.
Businesses That Benefit Most
- Growing SMEs that need strategy but not a full-time hire
- Businesses with seasonal or fluctuating demands
- Owners spending too long on finance instead of running the business
When Does an In-House Finance Director Make More Sense?
There comes a point where the workload justifies a permanent hire.
If your finance function is large, your transactions are complex, or you genuinely need someone in the building every day, an in-house FD is the better fit. Larger companies with sizeable teams and constant decision-making usually reach this stage.
The test is simple. If you would keep a full-time FD properly busy all the time, and the value they add clearly beats their cost, employing one makes sense.
When Should You Switch from an Outsourced Finance Director to an In-House FD?
Plenty of businesses start with an outsourced finance director and move to a permanent hire as they grow. That is the healthy and logical progression.
Watch for the signs. They include: your outsourced FD being asked for more days each month; the finance team has grown and needs daily leadership; decisions cannot wait for the next scheduled session with your outsourced FD. When the numbers point towards a full-time role earning its keep, it is time to switch.
A good outsourced FD will tell you when that moment arrives, and also help you recruit their replacement.
Which Option Is Right for Your Business?
Ask yourself three questions: how much senior finance work do you genuinely have each month? Can you justify the full cost of a permanent salary? Do you need someone present every day, or just at the right moments?
If your needs are strategic and periodic, outsourcing wins. If they are daily and constant, an in-house FD is worth the investment. Most growing businesses sit firmly in the first camp for several years.
