What is a Fractional CFO?

A fractional CFO, or Chief Financial Officer, is a financial expert who provides CFO services to startups and small businesses on a part-time, contract, or project basis. They offer the strategic financial guidance, management, and oversight typically associated with a full-time CFO, but at a fraction of the cost.

A startup may need a fractional CFO when:

  • Experiencing rapid growth or preparing for a significant financial event, such as fundraising or an acquisition
  • Lacking in-house financial expertise or resources
  • Facing complex financial challenges, such as cash flow management or financial forecasting
  • Needing strategic financial guidance to optimize business performance

When selecting a fractional CFO, consider the following factors:

  1. Experience: Look for a CFO with a proven track record in your industry or with similar businesses.
  2. Qualifications: Ensure they possess relevant financial certifications, such as a CPA or CMA.
  3. Strategic mindset: A good fractional CFO should be able to provide strategic financial guidance and help develop growth strategies.
  4. Communication skills: Effective communication is crucial for working collaboratively with your team and presenting financial insights to stakeholders.
  5. Flexibility: Choose a CFO who can adapt to your startup’s needs and work on a part-time or project basis.

What Should a Fractional CFO Do at a Startup?

A fractional CFO should:

  • Develop and implement financial strategies to support growth
  • Oversee financial management, including budgeting, forecasting, and cash flow management
  • Establish financial controls and processes to ensure accuracy and compliance
  • Analyze financial performance and provide insights to inform decision-making
  • Support fundraising efforts, such as preparing financial documents and negotiating with investors
  • Provide financial guidance during significant events, such as mergers, acquisitions, or IPOs

How Much Should You Pay a Fractional CFO?

The cost of hiring a fractional CFO can vary based on factors such as their experience, qualifications, the scope of work, and the size and complexity of your startup. In general, fractional CFOs may charge hourly rates ranging from $100 to $400 or more, or a monthly retainer fee between $3,000 and $10,000.


A fractional CFO can provide valuable financial expertise and guidance for startups looking to scale and optimize their financial performance. By understanding when to hire a fractional CFO, what to look for, and the costs involved, you can make an informed decision about whether this financial resource is the right fit for your startup.
