Types of CFO Services: Which Is Right for Your Company?

There is no one-size-fits all approach to identifying the right CFO. Depending on your company stage, challenges, and goals for the future, explore if a fractional, interim, or full-time executive makes the most sense.

CFO Type Engagement Length Typical Hours/Week Best For Pros Cons
Fractional CFO Ongoing, part-time (long-term) 4–20 hours Growth-stage, founder-led, or lean companies that need strategic finance help without a full-time hire Strategic insight + flexibility; consistent relationship over time; cost-effective Working around a part-time schedule
Interim CFO Full-time, short-term (3–18 months) 40+ hours Companies with a CFO departure or other transition (crisis, growth needs, M&A) Full firepower fast; flexible contracts; stabilization and structure to hand off to perm hire Higher cost; shorter runway;
Full-Time CFO Permanent 40+ hours Companies seeking an executive to keep the trains running Deep focus; embedded leadership Expensive; hard to change if a mismatch

What are the Responsibilities of a Fractional CFO?

Fractional CFOs do more than clean up your numbers. They serve as strategic partners to:

  • Build and oversee financial systems and reporting
  • Forecast cash flow and guide capital allocation
  • Establish KPIs and dashboards
  • Support or lead fundraising and investor relations
  • Strengthen internal finance teams
  • Identify risks and drive better decisions

Read: What Does a Fractional CFO Actually Do?

“A good CFO has the skills of looking forward. They understand business drivers, they understand not only their business, but they understand their customer’s business, and they understand their competitor’s business.”

— Vic, RED Team CFO

What to Expect from the Relationship

  • Flexibility
    Most fractional CFOs work a few hours or days a week, depending on your company’s needs. Their contracts are adaptable — easy to scale up during times of growth or complexity, or scale down once the financial foundation is in place. No long-term commitments, no red tape. Some are onsite. Some work remotely. All RED Team CFOs adapt to your operating style and stage.
  • Accountability
    Fractional CFOs are true operators. They are not acting in a consulting capacity from the sidelines, but step in and own it. They have decision-making authority, manage financial operations, and are accountable for results. Think of them as hands-on operators — building systems, solving problems, and making sure the business moves forward.
  • Collaboration
    A great fractional CFO doesn’t just manage numbers — they build relationships. They work shoulder-to-shoulder with founders, CEOs, boards, and investors to align financial strategy with business goals. Whether it’s sitting in on board meetings or mentoring internal team members, they act as a trusted partner across the organization.
  • Efficiency
    Fractional CFOs bring exactly the level of expertise you need — without the full-time salary, severance, benefits, or overhead. They focus their time where it matters most, bringing years of experience to solve complex problems faster and smarter than a generalist hire.

How Much Does a Fractional CFO Cost?

A fractional CFO will assess the scope of work, time commitment needed, and typically quote an hourly rate or fixed monthly retainer. Other benefits of the Fractional CFO cost structure include:

  • Scalable based on your needs
  • No severance, benefits, or overhead
  • Flexible contracts, easy to end when services no longer needed

Choosing the Right CFO

Not all finance leaders are created equal. The best fractional CFOs:

  • Have held P&L responsibility
  • Ask hard questions and offer even harder truths

Many have worked across multiple industries, bringing a fresh outside perspective and best practices that help companies avoid blind spots and accelerate results.
