Part-time CFO support for growing businesses including strategic planning, fundraising, board reporting, and financial leadership without full-time cost.
A Fractional CFO is a part-time, senior finance leader who owns financial strategy, fundraising support, and board reporting at a fraction of a full-time CFO cost. Westfin embeds 2–8 days/month: managing the finance function, building the operating model, running monthly board packs, and preparing investor data rooms when you raise.
Specific numbers matter when planning. These are the figures we work with day-to-day, sourced from current HMRC and Companies House guidance.
We work to the published HMRC, Companies House and FRC guidance. The primary sources we cite when advising clients:
A London health-tech raises £3m Series A. Westfin (3 days/month) builds the post-money 36-month plan, hires a Senior Finance Manager into the team, sets up monthly board reporting (rule-of-40, ARR / NRR cohorts, net burn vs runway), and runs quarterly investor updates. Monthly fee: £4,500 vs ~£18,000 for an equivalent full-time CFO.
