FAQ
Questions accountants & finance pros ask before starting
Is fractional CFO work realistic for a senior accountant?
Yes. Most pre-Series A startups can't afford a full CFO. £600-£1,200/month for 4-8 hours/week of fractional finance leadership is now a recognised market category in the UK and US.
How do I find startup clients?
AngelList, YC W26 batch directory, Indie Hackers — anywhere founders ask about hiring. Pitch one specific deliverable (model review, board pack, runway analysis) per intro, not 'I'm available for fractional work'.
Will my firm have a problem?
Most Big-4 and mid-tier firms allow side income with declared conflicts. Avoid taking work in your firm's verticals or any client whose audit you've worked on. Get it in writing.
