Most small businesses cannot afford a full-time CFO—and do not need one. What they do need is CFO-level thinking, which can be purchased in a fractional arrangement or built internally at a much lower cost.
What a CFO Actually Does
A CFO is primarily responsible for financial strategy, capital allocation, and financial reporting. Below about $5M in annual revenue, most of these responsibilities can be handled by a sharp bookkeeper for day-to-day operations, an accountant for taxes and compliance, and a fractional CFO for the strategic layer—at a fraction of the cost of a full-time hire.
Signs You Need More Financial Help
You are making significant decisions without confidence in your numbers. Your cash position surprises you at month-end. You are considering taking on debt or outside investment. You are planning to hire aggressively or enter a new market. Any of these signals suggests you need better financial infrastructure, which might mean a fractional CFO or upgrading your bookkeeping.
Key Takeaways
- Full-time CFO is typically justified above $5M ARR or in complex fundraising/M&A situations.
- Fractional CFOs give you strategic financial leadership at 10-20% of the cost.
- Most companies under $5M need better bookkeeping and a good CPA more than they need a CFO.
