Fractional CFO Services: Your Startup's Secret Weapon

Times of growth and expansion are exciting for startups, but success brings new obstacles. One of the biggest challenges scaling startups face is figuring out how to manage their financials without breaking the bank. Hiring a full-time CFO is costly, but without an expert CFO's support, founders make decisions blind.

Hiring a fractional CFO is a cost-effective alternative that provides the strategic guidance of a full-time CFO. A fractional CFO makes efficient decisions based on your startup’s financial health.

Read on for everything you need to know about these services and tips to help you determine if hiring a fractional CFO is right for your business.

What Is A Fractional CFO?

A fractional CFO (sometimes called an outsourced CFO or virtual CFO)  is a financial professional who provides CFO services on a part-time or project basis. Think of them as freelance finance specialists who contract with your business and offer similar services to a regular CFO without long-term, full-time, often expensive commitments.

A full-time CFO, fractional CFO responsibilities go beyond basic bookkeeping. We’ll cover a fractional CFO’s roles in more depth below, but these can include creating a multiple-year financial model, building reliable projections, managing cash flow, creating an equity and debt financing strategy, providing an annual startup budget, and more.

When ready, you can easily hire an outsourced CFO directly or through a SaaS fractional CFO platform that connects your startup with the right virtual CFO for your needs. The convenience of getting access to the support of an expert CFO in minutes rather than months—along with the lower prices of short-term commitments—makes fractional CFOs a popular option for startups.

Fractional CFO VS Full-Time CFO

A fractional CFO is a professional who works part-time or project-based for your business and gets paid per project or hours worked. This also means that fractional CFOs can choose to work for multiple clients simultaneously. However, fractional CFOs have often worked with various businesses and can bring a fresh perspective to your financial operations.

On the other hand, a full-time CFO is a professional who works for your business full-time and is available to work on your financial matters exclusively – this is one of the main advantages. Full-time CFOs are also paid an annual salary for their services and are eligible for company benefits. However, a full-time CFO salary averages $300,000 - $500,000 per year, which most early-stage startups can’t afford.

Both types of CFOs can provide the same services. However, one of the main benefits of a fractional CFO for startups is cost savings. Since you only pay for their work hours, you can save money compared to hiring a full-time CFO, who requires a monthly payment.

Should I Hire A Fractional CFO And When?

As a startup, making the most of your budget is critical, so a fractional CFO might be a good option to avoid spending more than you have to. To determine if hiring a fractional CFO is right for your business, look at your budget, current needs, and long-term goals.

If your startup doesn’t have the budget to hire a full-time CFO ($300,000 - $500,000 per year), then fractional CFO services are ideal. Once you know how much you’re willing to pay, look at your needs. If you only need, for example, a three-year financial forecast or an annual budget that takes a few weeks to create, you can hire a fractional CFO to take care of it.

After you determine whether or not you should hire a fractional CFO instead of a full-time employee, you can decide on the right time to do so. Some common situations indicate the right moment to hire a fractional CFO:

  • You're having trouble balancing your financial obligations, such as paying bills on time, managing your cash flow, or reporting to investors.
  • You're planning to expand your business.

What Does A Fractional CFO Do At A Startup?

Fractional CFOs can help with any financial task you agree on, mainly related to financial planning and analysis. Below are a few key problems that they can solve for your startup.

Determine Your Financial Health

Many startups are run by entrepreneurs who may not have a background in finance. As a result, they may struggle to understand their true financial situation. Fractional CFO accounting services can help a startup make sense of its financial reports and provide the insights and guidance needed to make better business decisions.

Manage Your Cash Flow

Cash flow is a key concern for startups, and unfortunately, many struggle to manage it effectively because they don't have the right guidance. Without proper cash flow management, businesses may be spending more money than they should without realizing it, which could lead to bankruptcy when they can’t pay the bills. A fractional CFO can help a startup with cash flow forecasting, developing strategies to improve it, and implementing systems to manage it more effectively.

Prepare Your Startup For Growth

Startups grow rapidly. So much so that managing this growth can be overwhelming and may lead to financial mistakes. A fractional CFO can help a startup plan for growth by developing detailed budgeting plans, projections, and reports. With these documents, you can allocate your budget better, prepare for the future, track your team’s performance, and give investors a big-picture POV.

Stay Compliant With Taxes

A fractional CFO can help startups identify tax deductions and credits they may be eligible for and develop strategies to defer or reduce their tax liability. They can also help startups prepare for tax season, ensuring that your tax returns are accurate and filed on time.

The Top 7 Fractional CFO Services Your Startup Needs

As your startup scales, new financial needs arise. To make the most of your budget, you need to consider key financial tasks that will support your growth. With fractional CFO services, you can take care of those key tasks without overspending. These are some of the best outsourced CFO services you should consider to boost your startup's growth.

1. Cash Flow Projections

One of the key roles of a CFO is to ensure the organization has a healthy cash flow. Fractional CFO services construct cash flow projections based on historical and current data to help you plan and make informed business decisions. This can include projecting cash inflows and outflows and identifying potential issues and opportunities.

2. Forecasting

Financial forecasts are estimates of a company's future financial performance based on historical data and expected future economic and market conditions. A fractional CFO can provide budget forecasting services to help you plan for the future. This can include forecasting revenue, expenses, and other key metrics. Using data and analytics helps you develop a more accurate and reliable view of the future for your business so you can plan ahead.

3. Fundraising Support

Fractional CFO services can provide critical support if your organization wants to raise funds. They can help by developing financial projections, building reports, and creating presentations for potential investors. These financial documents are key during fundraising rounds because they all depict your startup’s present and expected future performance. Plus, investors don’t often fund startups without them. They can also help you identify your business's most appropriate funding sources and assist with fundraising.

4. KPIs/Metrics Tracking

KPIs are essential to any business’s financials because they measure your team's performance. However, keeping track of these metrics can be challenging for startups without a full-time CFO. A fractional CFO can assist in tracking key performance indicators and other important metrics, such as revenue growth or profit margin. By tracking these metrics, you can measure the success of your business and make data-driven decisions. These professionals can also track their own CFO KPIs.

5. Financial Modeling

A fractional CFO can do financial modeling for startups to assess the feasibility of new projects, investments, or business strategies. This can help you avoid costly mistakes because financial models like the Sensitivity Analysis predict what would happen to your financials in certain situations. For example, how your financials would be affected after increasing your prices. This way, you never have to make decisions in the dark. Fractional CFOs can also provide guidance and support on using their financial models effectively and making the most of the insights they provide.

6. Annual Business Budgeting

This type of service can also assist with developing a comprehensive startup budget that considers projected revenues, expenses, and financial goals. They can also help the startup monitor its financial performance throughout the year and adjust the budget as needed. This can help the startup stay on track with its financial objectives and make informed decisions about resource allocation.

7. Go-To-Market Strategy Creation

A go-to-market strategy is essential to launching and growing a startup. A fractional CFO can help create a go-to-market strategy by providing revenue forecasts, analyzing market trends, developing pricing strategies, and developing financial models to ensure your launch is financially viable. Additionally, the fractional CFO you hire can help identify potential funding sources to support the go-to-market strategy.

How Much Does A Fractional CFO Cost

The cost of hiring a fractional CFO depends on several factors, including the individual's experience and qualifications, the scope of services provided, and the duration of the engagement. There are two main ways to pay a fractional CFO:

  • Hourly rate – The most common way part-time CFO professionals charge is by the hour. Usually, they record their work hours and send you an invoice every pre-defined period. You can also use time-tracking software to ensure all recorded hours are accurate. You can expect a rate of around $300 per hour for highly skilled professionals. With this payment method, you won't know exactly how much you will pay every month since it will depend on the worker.
  • Monthly payment – Monthly payments offer a more predictable and consistent cost. This works by determining how many hours of assistance and services you need and then paying a flat monthly fee. This fee can range from $1,000 to tens of thousands of dollars, depending on the level of support needed.

Plus, there may also be additional costs for expenses such as travel. Be sure to discuss these costs with the CFO upfront to avoid any surprises.

Using fractional CFO services is much more cost-effective than a full-time finance team since they can do different financial operations across different roles part-time. A full-time finance team could cost you over $500,000 per year, considering how much a CFO makes and all the other roles it involves. You don’t have to hire a CFO, accountant, payroll manager, and more. Fractional CFO services can take care of all of it.

What Makes A Good Fractional CFO?

When hiring a fractional CFO, you need to be familiar with the characteristics of good CFOs to choose the right person. These are the main skills you should consider for your fractional CFO job description.

Excellent Communicator

Good CFOs can clearly and effectively explain complex financial concepts to non-financial stakeholders, such as founders and investors. This way, other decision-makers can understand the company's financial situation, and everyone stays on the same page.


Attention to detail is key when it comes to financial operations. A mistake in your books could result in bad decisions or even a lack of compliance. Great CFOs keep track of all the many moving parts of a startup's financial operations, including budgets, cash flow, and performance metrics, making sure there is no mistake in any data or calculations.

Strategic Thinker

Top fractional CFOs look beyond the numbers and see the bigger picture of how the startup's financial decisions will impact its overall growth and success. They can provide valuable advice and guidance on long-term financial planning and help the startup make intelligent decisions to drive growth.

Can’t Founders Handle Fractional CFO Responsibilities?

As a startup founder, you’re probably tempted to take on the role of CFO to save money and retain control of the financial side of your business. You could technically do this successfully, but this approach can be risky and hinder your company's growth and success.

A CFO is responsible for managing the financial health of a business, developing financial strategies, forecasting revenue and expenses, analyzing market trends, and much more. These responsibilities require a high level of training and focus, and trying to handle them on your own can expose your business to several risks.

For example, Zeni has worked with startups who either have no financial plan for their business or think they have the right insights and projections but later discover their cash runway is actually three months instead of one year.

Additionally, not having a dedicated CFO can prevent your business from accessing the financing and investment opportunities it needs to grow. Instead of trying to handle the CFO role on your own, consider outsourcing CFO services.

The Zeni founders tried handling all CFO services on their own while building their first two startups and discovered how complicated it was—thus, Zeni was born. We understand how alarming this can be to founders, so we paved the way for startups to have a "CFO in their pocket" at all times. This way, they can make informed business decisions and plan ahead with peace of mind.

Protect Your Financial Health With A Fractional CFO

Fractional CFO services are financial tasks such as financial planning, analysis, budgeting, and fundraising done by part-time professionals. This means you can take care of these critical tasks for your startup's growth and only pay when you truly need them.

This is why fractional CFOs are the best method for startups to implement these types of services instead of hiring a full-time CFO or building out a full internal finance team—especially when it comes to cost savings.

Some of the main services fractional CFOs provide include:

You might think that you can handle these responsibilities independently as a founder, which may be true. But running a startup is a challenging job on its own, and CFO tasks are just as demanding. So, not being entirely focused on finances or not having enough experience could lead to costly mistakes. Why risk the financial health of your business when you could hire a fractional CFO?
