  • Cash and working capital oversight to ensure resilience
  • Management information that enables better decisions
  • Board-level strategic input to support you and your investors

Our CFOs embed directly into your team — acting like a trusted internal leader, not an outsider. Learn more in our article How Can a Fractional CFO Transform Your Bottom Line?.

Why Use a Part-Time CFO?

Hiring a full-time Chief Financial Officer (CFO) can be expensive — but that doesn’t mean you have to go without strategic financial leadership. With a part-time CFO, you get access to experienced, board-level financial insight on flexible terms. You only pay for the support you need — whether it’s a few days a month or a few days a week. At Secantor, our CFOs have supported hundreds of UK SMEs across sectors, bringing commercial acumen, fresh thinking and proven best practices to every engagement.

What Does a Part-Time CFO Do?

Our part-time CFOs take ownership of your financial function — from day-to-day control to long-term strategy. We work alongside your team to build confidence, improve profitability, and prepare your business for investment, sale or growth.

Typical CFO responsibilities include:

  • Designing and developing an effective internal finance function
  • Recruiting, training and mentoring finance staff
  • Providing hands-on financial oversight and technical leadership
  • Building 3–5 year financial forecast models (P&L, balance sheet, cashflow)
  • Producing and interpreting monthly management accounts
  • Providing analysis and commentary on business performance
  • Identifying profitability drivers by product, customer, channel or geography
  • Driving operational improvement and cost efficiency
  • Securing funding and managing investor or lender relationships
  • Creating short- and long-term cashflow forecasts to prevent surprises
  • Improving working capital and balance sheet control
  • Delivering financial governance and internal control frameworks
  • Supporting transactions, M&A activity and due diligence
  • Leading major financial projects including systems implementation
  • Providing interim CFO cover during transition periods

We don’t just advise. Your Secantor CFO becomes part of the team — building trust, driving performance, and delivering results.

Frequently Asked Questions: Part-Time CFOs

A part-time CFO is a senior financial expert who works with your business on a flexible basis, providing high-level financial strategy, oversight and board-level input. They offer the benefits of a full-time CFO without the permanent cost.

They lead financial strategy, produce and interpret management accounts, build financial models, manage risk, guide funding decisions, support acquisitions or exits, and ensure your board has timely, accurate financial insight.

Part-time CFOs are ideal for SMEs with growing complexity but without the need for a full-time finance leader. At Secantor, we typically support businesses with £3m–£50m turnover, though some clients are smaller or larger.

While the roles often overlap, a Finance Director typically focuses on internal financial control and reporting. A CFO adds a layer of strategic foresight, often acting as a key advisor to the CEO or owner and supporting investor relationships. In SMEs the role is ineffect one and the same.
