What is a Fractional CFO?

A fractional CFO is a highly experienced financial expert who works with businesses on a part-time or contract basis. Unlike a full-time CFO, they are available for a specific number of hours per week, but they bring the same level of strategic insight and financial leadership to the business.

‍

What Does a Fractional CFO Actually Do?

A fractional CFO helps you look beyond day-to-day bookkeeping and think long-term about your business. They offer a range of services, such as helping startups to raise venture capital, improve cash flow, collaborate on growth and profitability strategies, and build financial systems.

They’ll work closely with you or your leadership team to interpret financial data and make smarter decisions for your business. Whether it’s pricing your services, deciding when to hire, managing runway, or mapping out future growth, a fractional CFO will help you turn numbers into a strategy.

Some fractional CFOs focus on different financial aspects of the business. For example, some focus exclusively on strategic financial planning, while others focus on the operational side of things. 

For startups and SMEs, this model is especially valuable. You gain access to executive-level thinking, but you only pay for the time and value you need.

‍

Does Your Business Need a Fractional CFO?

If your startup is growing quickly but you don’t have clear visibility into your financials, or have trouble understanding financial reports, it may be time to consider a fractional CFO. Many startups reach a stage where a bookkeeper or traditional accountant is no longer enough. If you are planning to raise funds, manage unpredictable cash flow, or trying to scale more efficiently, a fractional CFO is built to handle and solve these challenges.

Even if you're not ready for a full-time CFO, you still need strategic financial leadership. A fractional CFO gives you exactly that, tailored to your current needs and budget.

Benefits of Hiring a Fractional CFO

As a small business owner, every decision you make counts when managing your finances. Therefore, the guidance of a fractional CFO would make a huge difference to your business’s sustained growth. A fractional CFO is your strategic partner, enabling your startup to navigate financial issues, make informed financial decisions and steer towards success.

• While your fractional CFO handles the finances, you, the CEO can focus on the other core business areas such as marketing, product development etc.

How Much Does a Fractional CFO Cost?

The cost of a fractional CFO can vary widely depending on their experience, and the complexity of your business such as the business size, service scope, and the industry . On average, the hourly rate for a Fractional CFO can vary anywhere between $80 to $150.
