How to Hire a Fractional CFO in the UK
From the first call to your first board-ready management accounts in 4 weeks.
Free 30-minute discovery call
We talk through your current finance setup, your immediate priorities (fundraising, cash flow, board reporting), and what success looks like in the next 90 days. No pitch, no obligation.
Scope and pricing in writing
Within 48 hours of the call you receive a written proposal: deliverables, monthly time commitment, fixed fee, and start date. No surprises, no day-rate billing.
2-week diagnostic phase
We review your books, financial model, contracts, and reporting. You receive a written diagnostic with the top 5 issues and how we will fix them in the first 60 days.
First board-ready management accounts
By the end of week 4 you have your first proper SaaS-aware monthly pack: P&L, cash flow, MRR waterfall, runway, KPI dashboard, and written commentary. Delivered every month thereafter.
Who Hires a Fractional CFO from ScaleWithCFO?
UK-based founders running SaaS, AI and tech businesses where the financial complexity has outgrown the spreadsheet.
UK SaaS founders £500K-£10M ARR
You have product-market fit, you are growing, but the numbers feel chaotic. Investors are asking harder questions. You are not ready for a full-time CFO at £200K+, but you cannot keep flying blind.
Pre-Series A founders preparing to raise
You need a proper financial model, a clean data room, and someone who can sit alongside you in investor meetings. You want a CFO with prior fundraising experience, not your accountant.
Founders 12-24 months from exit
You want to maximise valuation. That means clean accounts, defensible projections, fixed gross margins, and a quality-of-earnings-ready data room. The work starts now, not the month before you go to market.
AI and deep-tech companies
You have unusual cost structures (compute, training, infrastructure) and you need a CFO who understands how to model them, present them to investors, and explain them in board meetings.
What's Included in Every Engagement
One fixed monthly fee covers all of the below. No day rates, no surprise invoices, no upsells.
Monthly management accounts and SaaS metrics dashboard
13-week rolling cash flow forecast
3-statement financial model with scenario planning
Board pack preparation and attendance (where required)
Fundraising support: data room, model, investor Q&A
Revenue recognition review (IFRS 15)
Unit economics and cohort analysis
Direct lines to your accountant, lawyer, and investors
Unlimited email support, ad-hoc calls included
Fixed monthly fee, 30-day rolling notice
Why Hire ScaleWithCFO Instead of an Agency
Most "outsourced CFO" firms sell you a senior partner in the pitch and then deliver the work through a junior team. ScaleWithCFO is the opposite: one ACA-qualified CFO, embedded directly with your team, no analysts in the middle, no quarterly partner reviews.
The model deliberately limits the number of clients we take on, so every engagement gets the depth of attention a fundraise or exit actually needs. If you want a name on a slide deck, hire a Big 4. If you want a CFO who picks up the phone, this is the right fit.
