A fractional CFO is a part-time Chief Financial Officer who provides senior-level financial leadership to companies that don’t need or can’t afford a full-time executive. For startups, this means getting strategic financial guidance during critical growth phases without committing to a $200,000+ annual salary.

Most startups hit a point where the founder is still handling finances but shouldn’t be. The books might be accurate thanks to a bookkeeper, but nobody is thinking strategically about cash runway, fundraising preparation, or what the numbers actually mean for the business. That’s the gap a fractional CFO fills.

For startups and high-growth companies specifically, a fractional CFO typically handles financial modeling, fundraising support, cash management, investor reporting, and strategic decisions. Financial modeling means building projections investors want to see and that you actually need for planning. This isn’t just a spreadsheet with numbers. It’s a working tool that helps you understand how hiring decisions, pricing changes, and growth rates affect your cash position.

Fundraising support is where the value often shows up most clearly. Preparing materials for investors, handling due diligence requests, and sitting across the table during negotiations takes experience. Investors ask hard questions about unit economics, customer acquisition costs, and revenue projections. Having someone who speaks their language and can back up the numbers makes a real difference in outcomes.

Cash management is critical because startups die when they run out of money. A fractional CFO monitors burn rate, extends runway where possible, and makes sure you know exactly how much time you have before you need more capital. This visibility alone prevents the scramble that happens when founders realize too late that they’re running low.

The difference between a fractional CFO and a bookkeeper is strategic versus transactional. Your bookkeeper records what happened. Your CFO helps you decide what should happen next. Both roles matter, but they solve different problems. Many Saratoga Springs, Utah bookkeepers offer both services because growing companies often need the foundation of clean books before strategic financial leadership adds real value.

Startups typically bring in a fractional CFO when they’re preparing to raise capital, experiencing rapid growth that’s straining their financial systems, or when the founder realizes they’re spending too much time on finance instead of product and customers. Some engage one early and keep them through multiple funding rounds. Others bring one in for specific projects like fundraising and then scale back.

The cost is usually a fraction of a full-time CFO, often $2,000 to $8,000 monthly depending on hours and complexity. That’s accessible for early-stage companies with some revenue or seed funding, and the return typically shows up in better fundraising outcomes, fewer cash surprises, and decisions backed by real analysis rather than gut feel.
