By Ashley FerroDecember 20, 2023

The top reason startups fail is running out of cash. This stark reality brings to light the critical role a CFO plays in a company's success 

But is a full-time CFO really the right investment for your business? 

When it comes to business finance, deciding between a fractional CFO and a full-time CFO can be a pivotal choice. This guide explores the key differences, benefits, and scenarios where each type of CFO can be the key to avoiding financial pitfalls and steering your company toward sustainable business growth and stability. 

What is a Fractional CFO? 

A fractional CFO refers to a Chief Financial Officer who offers their expertise on a part-time or contract basis, as opposed to being a full-time executive employee.

This model allows companies, especially startups and small-to-medium enterprises (SMEs), to gain access to high-level financial expertise without the expense of a full-time salary and benefits package. 

What Does a Fractional CFO Do? 

What Does a Fractional CFO DoA fractional CFO performs a wide array of functions, central to which is steering the financial direction of the company.

Their roles typically include: 

  • Strategic financial planning and analysis: The fractional CFO is crucial in developing and refining a company's financial strategy. They analyse financial data, forecast future trends, and ensure that the company's financial plans align with its overall goals. As strategic thinkers, they provide insights and recommendations for business growth and stability. 

  • Capital raising and investment management: Startups and expanding businesses often need external funding to fuel their growth. A fractional CFO plays an essential role in this process. They prepare financial statements and projections, work on valuations, and engage with potential investors. They guide the business through fundraising rounds, ensuring that financial presentations are compelling and that the company is valued correctly. 

  • Audit navigation and compliance: Ensuring compliance with financial regulations and successfully navigating through audits is another key responsibility of a fractional CFO. They manage financial reporting, ensure adherence to accounting standards, and oversee the audit process. This role is particularly vital in maintaining the financial integrity and transparency of the business. 

  • Budget management and cost optimisation: They oversee budgeting and identify areas for cost reduction and efficiency improvements. This involves monitoring spending, evaluating financial performance against the budget, and making recommendations for cost-saving measures. 

  • Financial risk management: A fractional CFO also identifies and manages financial risks. They develop strategies to mitigate these risks, ensuring the financial stability of the company. 

  • Advisory and decision support: They serve as advisors to the CEO and board members, providing critical financial insights that inform decision-making. This includes analysing market trends, competitor analysis, and advising on financial implications of business decisions. 

  • Operational financial management: Beyond strategic planning, fractional CFOs often get involved in the day-to-day financial operations. This can include overseeing accounts payable and receivable, managing cash flow, and ensuring effective financial controls are in place. 

  • Stakeholder management: Communication with stakeholders, including investors, board members, and financial institutions, is another key area. They represent the financial interests of the company and ensure transparent communication regarding financial performance and forecasts. 

Fractional CFO vs Full-Time CFO 

When deciding between a fractional CFO and a full-time CFO for your business, it’s like choosing between hiring a consultant or a full-time executive.  

Differences Between Fractional CFO & Full-Time CFO

Job Role & Commitment 

  • Full-time CFO: Works exclusively for one company. They are involved in day-to-day operations and long-term strategic planning. 

  • Fractional CFO: Works part-time or on a contractual basis, possibly for multiple companies. Focuses on specific projects or areas within a company. 


  • Full-time CFO: Typically incurs a higher cost due to a full-time salary, benefits, and other employment-related expenses. 

  • Fractional CFO: Generally more cost-effective, as they are paid only for the time or services provided. 

Involvement in the Company 

  • Full-time CFO: Deeply integrated into the company, understanding its culture, dynamics, and detailed operational processes. 

  • Fractional CFO: While skilled, they may not have as deep an understanding of the company’s culture due to their part-time or temporary role. 

Focus Areas 

  • Full-time CFO: Has a broader focus, handling all aspects of the company’s finances, including long-term financial planning and day-to-day financial decisions. 

  • Fractional CFO: Often brought in for their expertise in specific areas like financial restructuring, preparing for investment rounds, or navigating significant transitions. 

When Should You Hire a Fractional CFO? 

When deciding whether to hire a fractional CFO or a full-time CFO, it's essential to consider the specific needs, size, and growth stage of your business.  

“One of the best things we did at Luna in the really early days was to get a fractional CFO. It took so much pressure off me because building models isn’t my strong point. I had to admit where my weaknesses are, but I made sure to plug that gap immediately.” 

When to Hire a Full-Time CFO 

Businesses in certain stages of growth and complexity require the dedicated oversight that only a full-time CFO can provide.  

Here are some situations where hiring a full-time CFO is ideal: 

  • For established companies with complex operations: Larger businesses with intricate financial structures benefit from a full-time CFO who can consistently manage these complexities. 

  • For high-revenue businesses: A company with substantial revenue and numerous transactions needs the full-time attention that a full-time CFO can provide to manage and oversee these financial activities. 

  • For strategic leadership: Companies at a stage where they need constant, high-level financial strategy and long-term planning will find a full-time CFO's dedicated presence invaluable. 

  • During times of stability and growth: In periods of steady growth, a full-time CFO can be instrumental in scaling the business sustainably and overseeing the expansion of financial operations. 

When to Hire a Fractional CFO 

On the other hand, a fractional CFO can be the perfect solution for businesses with different needs - especially those in transitional phases or requiring specialised expertise without the commitment of a full-time executive.  

Here’s when opting for a fractional CFO is advantageous: 

  • For startups and SMEs: Startups and smaller businesses often find the flexible and cost-effective nature of a fractional CFO perfectly aligned with their financial management needs. 

  • During significant transitions: Businesses going through rapid growth, restructuring, or preparing for significant events like acquisitions can benefit from the specialised expertise of a fractional CFO. 

  • For specialised expertise: When facing specific financial challenges or seeking expertise in areas like tax strategy or fundraising, a fractional CFO can provide this expertise on a more flexible basis. 

  • To supplement existing teams: If your business already has a financial team but requires additional strategic guidance, a fractional CFO can fill that gap without disrupting the existing team structure. 

Is a Fractional CFO Worth It? 

“Fractional CFOs can save startups money on a traditional CFO role, while also providing the necessary expertise needed to navigate a booming VC and investment market.”

Evaluating whether a fractional CFO is worth the investment involves understanding the unique benefits they bring to a business 

Benefits of a Fractional CFO 

Benefits of a Fractional CFO

1. Cost-Effectiveness for Budget-Conscious Businesses 

Fractional CFOs are particularly beneficial for startups or small businesses where budget constraints are a primary concern.  

For instance, a fledgling tech startup might need high-level financial guidance to manage its limited budget effectively and prepare for funding rounds. A fractional CFO provides this expertise without the cost of a full-time executive, enabling the startup to utilise expert financial advice while conserving resources. 

2. Flexibility During Business Fluctuations 

Businesses experiencing seasonal fluctuations or rapid growth phases find the flexibility of a fractional CFO highly advantageous.  

Consider a retail company that sees significant sales increases during the holiday season. A fractional CFO can be brought in to manage these peak times, offering strategic financial planning without the commitment of a year-round salary. 

3. Diverse Experience Across Industries 

Fractional CFOs often bring a breadth of experience from working across various industries and markets. This diverse experience is particularly valuable for businesses looking to expand or navigate new challenges.  

For example, a family-run business planning to expand into new markets can benefit from a fractional CFO's insights gained from similar expansions in other sectors, providing a broader perspective for strategic decision-making. 

4. Strategic Leadership During Restructuring 

In times of significant transition, such as a company restructuring, a fractional CFO's strategic expertise is invaluable. They can guide a manufacturing firm through a financial restructuring process, ensuring that the company maintains its financial health while undergoing organisational changes. 

5. Specialised Expertise for Unique Financial Needs 

Non-profit organisations or companies with unique financial requirements can leverage the specialised expertise of a fractional CFO.  

For example, an NGO dealing with complex grant funding and reporting can greatly benefit from a fractional CFO skilled in non-profit finance, ensuring compliance and effective financial management. 

What to Look for When Hiring a Fractional CFO 

Hiring a fractional CFO involves a unique set of considerations, distinct from those associated with a full-time CFO.  

What to Look for When Hiring a Fractional CFOHere are key factors to consider: 

  • Industry-specific experience: Seek a CFO with experience in your industry or related sectors. They should understand the specific challenges and opportunities your business faces. This experience ensures they can hit the ground running and provide relevant insights. 

  • Proven track record in key areas: Look for a history of success in areas critical to your business, such as fundraising, cash flow management, or financial restructuring. Evaluate their past achievements and how they’ve impacted other businesses. 

  • Strategic thinking and flexibility: A good Fractional CFO should not only manage finances but also offer strategic insights to guide growth and efficiency. Their ability to adapt to your business’s changing needs is crucial. 

  • Strong communication skills: They should be able to clearly explain complex financial concepts to team members at all levels of financial literacy. Good communication fosters better decision-making across the company. 

  • Technological proficiency: Ensure they are comfortable with the latest financial software and technologies. This is especially important if your business relies heavily on tech solutions. Ask about specific tools they’ve used and how they’ve leveraged technology in previous roles. 

  • Cultural fit: Even as a part-time executive, the Fractional CFO should align with your company’s culture and values. Their work style and approach should complement your team’s dynamics. 

  • References and testimonials: Check references and seek testimonials from their past clients. This can provide insights into their work ethic and effectiveness. Focus on feedback related to their impact and working relationships. 

  • A clear understanding of your business model: They should quickly grasp your business model and financial operations. Their understanding will enable them to provide tailored advice and solutions. 

  • Availability and commitment: Discuss their availability and ensure it aligns with your business needs. Since they might be working with other clients, confirm their commitment level to your project. 

  • Result-oriented approach: Choose a CFO who sets clear goals and metrics for success. Their focus should be on delivering tangible results for your business. 

The Future of CFO Roles in Business 

As we look to the future, the roles of CFOs, both fractional and full-time, are evolving with the changing face of business. The days when CFOs were only seen as financial gatekeepers are giving way to a more dynamic role. Now, they're increasingly stepping into the spotlight as crucial contributors to business strategy and innovation. 

"Finance has always had a central controlling role in business, in achieving targets, creating stakeholder value and reporting to investors at large. That’s now expanded beyond traditional accounting/finance. As CFO, now I am responsible for many things beyond the traditional finance function." 

For startups and smaller companies, fractional CFOs are becoming a popular choice. They bring the necessary financial expertise without the cost of a full-time executive, fitting perfectly into the agile and ever-changing nature of these businesses. 

In essence, whether fractional or full-time, the CFO's role is becoming more diverse and central to a business's success. It's a role that now demands not just financial expertise, but also strategic thinking and the ability to adapt quickly to new business landscapes.
