Can a fractional CFO scale with the company?
Sometimes. Some fractional CFOs grow into full-time roles; others stay fractional and the company eventually hires elsewhere. Plan for either outcome from the start.
Comparison ยท Decisive verdict
Fractional CFO vs Full-Time CFO
Short answer
Fractional CFO suits the stage under $5M revenue with quarterly financial cycle. Full-time CFO suits the stage over $15M revenue with board reporting and active capital activity. The middle ($5M-$15M) is the uncomfortable transition zone where the right move depends on capital event timing and operating complexity.
When the company is below $5M revenue or in a quarterly financial cycle
Choose Fractional CFO when
- Revenue is under $5M and growth is steady.
- Financial cycle is quarterly, not weekly.
- Basic budgets and forecasts are in place; need senior review, not full-time build.
- A capital event or growth decision is on the 12-month horizon but not active today.
When the company is above $15M revenue or actively engaged with capital markets
Choose Full-Time CFO when
- Revenue is above $15M with multiple legal entities, tax jurisdictions, or business lines.
- Active capital markets engagement: fundraising, M&A, restructuring, or IPO preparation.
- Board reporting requires weekly financial discipline beyond quarterly reviews.
- Treasury, lender relationships, and complex working capital management need standing leadership.
When neither fits
When the company is below $1M revenue or operating at a level where a bookkeeper plus a tax accountant covers the work. Either CFO at that scale produces drag, not value.
Side-by-side
| Dimension | Fractional CFO | Full-Time CFO |
|---|---|---|
| Engagement shape | 1-3 days per week | Full-time role |
| Cost | $8K-$20K per month | $200K-$400K+ per year fully loaded |
| Time to value | 8-12 weeks | 6-12 months |
| Right at revenue | $1M-$5M | $15M+ |
| Transition zone | $5M-$15M depends on capital activity | $5M-$15M depends on capital activity |
| Risk of mismatch | Low; defined engagement | High; bad hire is 12+ months to unwind |
Common questions
When should I hire a full-time CFO?
When revenue exceeds $15M, when capital markets activity is continuous, when board reporting demands weekly financial discipline, or when treasury and lender relationships need standing leadership. Any single trigger justifies the hire; multiple triggers makes it overdue.
Is a fractional CFO worth it under $1M revenue?
Usually no. A bookkeeper plus a tax accountant covers most of the work at that scale. A fractional CFO at that revenue level often produces analysis that nobody implements.
Can I use a fractional CFO during a capital event?
Yes, for the duration of the event. Many companies hire a fractional CFO specifically for fundraising or sale preparation, then either upgrade to full-time or release the role after the event.
