What is a Fractional CFO?

A Fractional CFO (Chief Financial Officer) is an experienced business executive who provides strategic financial leadership and advisory services on a part-time basis.

Instead of a single full-time employer, they split their time across multiple businesses, providing high-level expertise at a fraction of the cost.

For the best experience, it’s important to look for a Fractional CFO that is CPA certified in the state you operate in.

Who Is It For?

Fractional CFOs are ideal for companies that have outgrown basic accounting but are not quite ready for the hefty price tag—often $150,000 to $300,000+ per year—of a full-time CFO. The role is primarily utilized by:

• Startups: Need help preparing for fundraising rounds, managing burn rates, and building investor-ready financial models.

• Small to Midsize Businesses: Companies experiencing rapid growth or facing cash flow hurdles who need an expert to analyze Key Performance Indicators (KPIs), forecast revenue, and steer long-term profitability.

• Nonprofits: Need specialized assistance with grant reporting, donor fund tracking, and transparent budget management.
