How many hours per week does a fractional CFO work?

Typically 8 to 16 hours per week for most growth-stage startups, which equals 1 to 2 days. Engagements can scale up to 3 days per week during fundraises, audits, or integrations. The exact time varies based on company size, stage, and the work pipeline.

Can a fractional CFO be remote?

Yes. Most fractional CFO engagements are remote-first with periodic in-person time for board meetings, investor pitches, or all-hands events. Modern tools (Slack, Zoom, shared spreadsheets, financial systems) make remote engagement seamless for finance work.

What is the difference between a fractional CFO and an interim CFO?

A fractional CFO is part-time, ongoing, and typically engaged for months or years. An interim CFO is full-time, temporary, and brought in to bridge a gap (often during a fundraise, exit, or while searching for a permanent CFO). The work overlaps; the time commitment and structure differ.

When should I replace my fractional CFO with a full-time CFO?

Usually around Series C or $30M+ ARR, when the company has enough complexity (international operations, M&A, audited financials, multiple revenue streams) to require constant attention. Some companies transition earlier if the CFO function becomes a daily strategic input rather than a weekly check-in.

Does a fractional CFO replace my accountant or bookkeeper?

No. A fractional CFO sits above the accounting function, not in it. You still need bookkeeping and accounting work done by a bookkeeper or controller. The fractional CFO reviews and uses that output for strategic finance work.

Can a fractional CFO help with fundraising?

Yes, this is one of the highest-value use cases. A fractional CFO who has been through multiple fundraises builds the investor model, prepares the diligence room, anticipates investor questions, and runs the negotiation alongside the founder. The value during a fundraise often justifies the entire annual engagement cost.

How long does it take to onboard a fractional CFO?

A good fractional CFO is productive within 2 to 4 weeks of starting. Onboarding includes reviewing financials, meeting key stakeholders, and understanding the business model. By month 2, they should be producing board-ready reporting and leading strategic conversations.
