A fractional CFO in the UK provides strategic financial leadership on a flexible, part-time basis — typically one to three days per week. For SaaS companies scaling from £500K to £5M ARR, a fractional CFO delivers the financial strategy, fundraising support, and investor-ready reporting you need without the £150K+ cost of a full-time hire.
A fractional CFO handles the strategic financial work that founders and bookkeepers cannot: building investor-ready financial models, managing cash flow forecasting, preparing for due diligence, and presenting to the board with a professional board pack.
Many UK SaaS founders search for a fractional finance director when what they actually need is CFO-level strategic thinking. A finance director manages operations — a CFO drives strategy, leads fundraising, and presents to investors.
