When Does a Growing Business Need a Fractional CFO?

Most owners do not wake up one day and decide they need a CFO. It creeps up on them. Revenue grows, the team gets bigger, and the finance questions stop being “did we get paid?” and start being “can we afford this hire?”, “which clients actually make us money?” and “what would a buyer pay for this?”. Your bookkeeper was never meant to answer those, and a full-time CFO is often more than the business needs or can justify. A fractional CFO sits in between. This guide covers how to tell when you are ready, and when you are not.

Bookkeeper, controller, CFO: who does what

The titles get used loosely, so it helps to be clear about the three layers of a finance function:

Each layer depends on the one below it. A CFO working from late or messy books produces confident-looking guesses, which is why the order matters. “Fractional” simply means you get the CFO layer for a set number of hours or a defined scope each month, rather than a full-time salary.

Eight signs your business is ready

1. You have been surprised by your bank balance. The business is profitable on paper but cash is always tight, and you only find out when a payroll or tax payment is due.
2. Revenue is growing but profit is not. You are busier than ever and taking home the same, and you are not sure which clients, services or locations are dragging the margin down.
3. A big decision is coming. A key hire, a second location, a large contract or a major equipment purchase, and you want to see the effect on cash before you commit.
4. You are talking to a bank or investor. Lenders and investors expect forecasts, clear financial statements and someone who can answer their questions confidently.
5. You are thinking about selling, now or in a few years. Buyers pay for clean, documented earnings, and preparing for that takes time. See what drives your business’s value.
6. You are pricing on instinct. You set prices by feel or by matching competitors, without knowing the true cost of delivering each service.
7. The business has become more complex. More than one entity, location or revenue stream, or partners who each want a clear view of their share.
8. The owner is the finance department. You spend evenings in spreadsheets instead of running the business, and important numbers live only in your head.

One or two of these is normal in any business. Three or more, especially cash surprises and a big decision on the horizon, is usually the point where CFO-level support pays for itself.

When it is too early

A fractional CFO is not the answer to every finance problem. It is usually too early if:

• The books are behind or unreliable. If the last few months are not reconciled, start with bookkeeping. A CFO spending their hours on cleanup is an expensive bookkeeper.
• The business is very early. If revenue is small and the main questions are still about finding customers, a good bookkeeper and a tax adviser will usually cover it.
• You want someone to own compliance only. Filing, payroll and tax deadlines are controller and tax work, not CFO work.

What a fractional CFO does, month to month

The exact scope depends on the business, but a typical monthly rhythm looks like this:

• A monthly check of results against budget and forecast, with a plain explanation of what changed and why.
• A rolling forecast and a 13-week cash flow forecast, so cash shortfalls show up weeks before they happen. Our guide to FP&A for growing businesses explains both.
• A short set of KPIs that actually drive the business, such as gross margin, days to collect, revenue per employee and cash runway. See our financial KPIs guide.
• Decision support for hiring, pricing, expansion and financing, modelled before you commit.
• Lender, investor or partner reporting, prepared and explained.
• Deal support when you are buying, selling or bringing in a partner, working alongside our M&A advisory.

What it costs compared with a full-time hire

The Bureau of Labor Statistics puts the median pay for financial managers, the category that includes controllers and finance directors, at $161,700 a year (May 2024). That is before benefits, payroll taxes and recruiting, and experienced CFOs typically cost more. For a business in the $1 million to $20 million revenue range, that is often more finance capacity than the business needs every week.

A fractional arrangement is scoped around what you need: a set number of hours, a monthly set of outputs, or a project such as preparing for a loan or a sale. Ask for the scope and the monthly deliverables in writing, so you can judge the value against what you get.

Questions to ask before you hire one

• Have you worked with businesses of our size and in our industry?
• What will we receive each month, and when?
• Who keeps the books, and how do you work with them?
• How do you handle tax planning and compliance, and who is responsible for it?
• How quickly do you respond when a decision cannot wait for the monthly meeting?
• What would you want to fix in our first 90 days?
