You Probably Don't Need a Fractional CFO Yet: A Stage-by-Stage Guide for Founders

Alex Wu, CFO Advisors · CFO Advisors Free Intermediate

This is the clearest map we found of the exact question you are asking: who should own your books at each stage, from founders doing it themselves, to a bookkeeper plus CPA, to a controller, to a full-time finance leader. It resists the usual push to over-hire and ties the call to concrete triggers (raising in the next six months, a board that cannot read your reports, headcount decisions made without a model) rather than a vanity title. Read it as a starting point to place your own company on the ladder, then adjust for your burn and how messy your numbers already are.

• The honest default sequence is founders, then a bookkeeper plus CPA firm, then a controller, then a fractional CFO, then a full-time hire. Skipping rungs tends to create a cleanup project later, not savings.
• Stage is a rough guide, not a rule: the real signals are an upcoming raise, a board that cannot interpret the numbers, and unit economics you cannot explain.
• A full-time finance lead usually earns its cost only around Series B or roughly 8M dollars plus in revenue, when the strategic work no longer fits a part-time engagement.
