How does an Interim CFO differ from a Full-Time CFO?

An Interim CFO delivers the same high-level financial leadership as a full-time CFO — but on a short-term, fixed-period basis. Rather than a permanent appointment, an Interim CFO is brought in to handle specific challenges or transitions such as growth, restructuring, or leadership gaps. You gain immediate access to strategic financial expertise without the long-term commitment of a full-time hire.

Why would an SME need an Interim CFO?

SMEs often encounter periods of change where immediate financial leadership is critical — for example, during a restructure, funding round, acquisition, or gap in senior finance. An Interim CFO steps in quickly to stabilise finances, support decision-making, and drive results. They bring the insight and capability of a seasoned CFO without the delay or commitment of a full-time hire — helping you navigate change with confidence. To explore the wider benefits of senior financial support, see our blog, Why every SME business should have a Finance Director

What does an Interim CFO actually do day-to-day?

An Interim CFO provides hands-on financial leadership from the moment they join. Typical responsibilities include: stabilising the finance function, producing and interpreting management accounts, building financial forecasts, managing cash flow, budgeting, advising on funding, supporting board meetings, and coaching your finance team. Their role is to solve problems fast, improve financial visibility, and enable better business decisions.

Can an Interim CFO also act as a Non-Executive Director?

Yes. At Secantor, many of our CFOs also act as Non-Executive Directors (NEDs). Our CFOs are commercially experienced, strategically minded, and have strong corporate governance expertise — making them well placed to contribute at board level.

Can an Interim CFO help with fundraising or investment?

Yes — a CFO plays a crucial role in preparing forecasts, engaging with investors or banks, presenting financial strategy, and structuring funding rounds. They bring credibility and clarity to the process.

How much does an Interim CFO cost?

The cost depends on the scope and frequency of support your business needs, but prices typically start at £1,200 +VAT per day. At Secantor, we tailor every engagement. Contact us for a no-obligation discussion to get a proposal aligned to your business needs and budget.

Do I still need an accountant if I hire an Interim CFO?

Yes — because their roles are different. An accountant operates outside your business and focuses on compliance, tax, and reporting. An Interim CFO works inside your business to provide strategic financial leadership. The two roles complement each other. Your CFO will often manage the relationship with your external accountant and ensure their advice is implemented effectively.

Is an Interim CFO suitable for my business size?

We typically work with UK SMEs with £3m–£50m turnover and 30–250 employees — but we also support ambitious smaller businesses preparing for growth or investment and we serve larger businesses too. If you’re experiencing growing complexity in your finances or strategic decisions, an Interim CFO can help bring clarity and control.

How quickly can an Interim CFO start?

We can often place a vetted, accredited CFO in your business within a matter of days. Every Secantor CFO is carefully selected and personally accredited to ensure they not only have the right technical expertise, but also the commercial experience and interpersonal skills to fit seamlessly into your team.

What makes Secantor different?

Unlike many providers, we don’t just offer CFOs or NEDs — we deliver the complete boardroom package. Our CFOs are also capable Non-Executive Directors, and every member of our team is personally accredited by Secantor. We don’t follow a rigid model — we match the right expert to your business and they tailor their approach to suit your needs.

How do I hire an Interim CFO?

The easiest way is to book a call with one of our experienced advisors. We’ll learn more about your business, explain how we work, and scope your requirements. Following a visit to meet you personally, we develop an in-depth understanding of your business needs allowing us to match you with a carefully selected FD based on your requirements, culture, and priorities. No obligation — just a conversation to see if we’re a good fit for you.

Interim CFO Services | Strategic Financial Leadership

Periods of significant change place new demands on business owners and leadership teams. Whether you are raising finance, preparing for sale, acquiring another business, replacing a departing CFO or leading a period of rapid growth, experienced strategic financial leadership can significantly improve the quality of decision-making and business outcomes.

An Interim CFO provides immediate access to senior strategic financial expertise without the long-term commitment of a permanent appointment. At Secantor, our Interim CFOs work alongside SME owners, directors and leadership teams to provide board-level financial leadership, commercial insight and practical support during critical stages of a business journey.

Many businesses first explore whether they need a CFO by reading our guide: When Does An SME Need A CFO?

What Is An Interim CFO?

An Interim Chief Financial Officer (CFO) is a highly experienced finance leader who joins a business on a temporary basis to provide strategic financial leadership during periods of change, challenge or opportunity. Unlike a Finance Director, who is typically focused on managing the finance function, reporting processes and financial controls, a CFO operates at a more strategic level. An Interim CFO helps business owners and directors make informed decisions about growth, profitability, funding, acquisitions, business value and long-term strategy.

Businesses often appoint an Interim CFO when:

preparing for acquisition or sale
raising investment or debt funding
navigating rapid growth
managing business restructuring
improving profitability and cash flow
replacing a departing CFO
leading a major strategic project
preparing for exit

An Interim CFO provides immediate expertise, independent perspective and experienced leadership exactly when it is needed most. For a deeper understanding of how strategic CFO support is typically delivered, read What Does A Fractional CFO Do In The First 90 Days?

Many SME businesses require strategic financial leadership but do not necessarily need a permanent full-time CFO. An Interim CFO provides immediate access to senior expertise during periods of growth, acquisition, fundraising, restructuring or leadership transition.

This allows business owners to benefit from experienced board-level support without making a long-term executive appointment. Many businesses later transition to a Fractional CFO arrangement once the immediate challenge or project has been completed.

When Should A Business Hire An Interim CFO?

Many SME businesses reach a point where important financial decisions carry greater risk and complexity than ever before. At these moments, business owners often benefit from experienced financial leadership that extends beyond reporting and compliance.
