Fractional CFO Advisors — ExpertStackHub

Q: What does a fractional CFO do?

A fractional CFO provides executive-level financial leadership part-time. They build and own your financial model, lead board and investor reporting, manage cash flow and burn rate, prepare your financials for fundraising, and hire or oversee your finance function. They typically engage 2–4 days per month.

Q: When does a startup need a fractional CFO?

Most startups benefit from fractional CFO support by $1–2M ARR or when approaching a Series A. Earlier, you need a financial model and clean books. At seed stage, a good accountant plus a part-time CFO advisor is sufficient. At Series A, board reporting and investor relations make a fractional CFO essential.

Q: What is the difference between a fractional CFO and a bookkeeper?

A bookkeeper records historical transactions and keeps your books clean. A fractional CFO interprets that data, builds forward-looking models, runs board reporting, advises on financial strategy, and represents your finances to investors. They operate at different altitudes — both are necessary.

Q: How much does a fractional CFO cost?

Fractional CFO engagements typically run $8,000–$20,000/month for 2–4 days of work per month. Project-based work (financial models, fundraising prep) runs $5,000–$35,000. This is typically 20–25% of the cost of a full-time CFO ($250K–$400K all-in).

Q: What should I look for in a fractional CFO?

Look for experience at companies at your stage (seed, Series A, B), familiarity with your business model (SaaS, marketplace, professional services), and fundraising track record. Ask to see financial models they've built and whether they've worked with investors at your target tier.
