What does a fractional CFO cost for a small business?

Fractional CFO services typically cost between $3,000 and $10,000 per month, depending on the scope of work and the complexity of the business. For companies between $3M and $75M in revenue, this is generally a fraction of what a full-time CFO would cost, which runs $300,000+ per year when salary, bonus, and benefits are included.

How is a fractional CFO different from a CPA or controller?

A CPA handles tax compliance and financial reporting. A controller manages the accounting function and close process. A fractional CFO owns forward-looking financial strategy: cash flow planning, capital structure, KPI design, and financial decision support for the leadership team. The roles are complementary, not interchangeable.

At what revenue stage does a fractional CFO make sense?

Most companies benefit from fractional CFO services when they hit $3M to $5M in revenue and are growing, facing a transaction, or dealing with financial complexity their current team can't manage. Revenue is one factor — the real trigger is when financial decisions start having consequences that outpace your existing financial infrastructure.

When to Hire a Fractional CFO: A Practitioner's Decision Framework

Most business owners ask this question six months too late. By then, they've survived a cash crisis, blown a deal because their financials weren't clean, or handed a lender something that made them look like amateurs. The decision to bring in fractional CFO services isn't complicated — but it does require you to be honest about what your current financial function can actually handle.

Forbes recently published a list of seven signs you're ready to hire a fractional CFO, and it's a reasonable starting point. But a checklist of signs doesn't give you a decision framework. At Pyek Financial, we work with companies between $3M and $75M in revenue, and the question we get most often isn't "what is a fractional CFO?" — it's "do I actually need one, and how will I know?"

That's the question worth answering.

The Cost Comparison That Should End the Debate

A full-time CFO costs $300,000+ per year when you factor in salary, bonus, and benefits. For a $10M company, that's 3% of top-line revenue sitting in a single finance role. Most companies at that size don't need 40 hours a week of CFO-level thinking — they need 10 to 15 hours a month of it, targeted at the decisions that actually move the needle.

Fractional CFO services typically run $3,000 to $10,000 per month depending on scope, complexity, and engagement frequency. That's CFO-level judgment at a fraction of the cost, applied exactly when and where you need it. The math isn't subtle.

The real trap is assuming that because you can't afford a full-time CFO, you just go without. That's not a cost-saving decision. That's a gap in your company's decision-making infrastructure.

What Your Bookkeeper and CPA Can't Do For You

Your bookkeeper records what happened. Your CPA files what the law requires. Neither of them is paid to tell you whether your pricing model is eroding your margins, whether your working capital can support a new contract, or whether your EBITDA is actually what a buyer will give you credit for when you sell.

That's not a criticism of bookkeepers or CPAs — it's a description of their jobs. A fractional CFO's job is different. The work is forward-looking: cash flow modeling, scenario planning, debt structure, KPI design, and board-level financial communication. If no one in your company is doing that work right now, that's not a gap you can paper over with a monthly close and a tax return.

The Five Triggers That Actually Indicate You're Ready

The Forbes framework is useful, but let's be more specific. Here are the triggers we actually see in practice:

Revenue between $3M and $15M, growing faster than your systems. At this stage, decisions start having seven-figure consequences, but the financial infrastructure often hasn't caught up. You're making pricing, hiring, and capital allocation decisions with gut instinct instead of models.
A transaction on the horizon. Selling, acquiring, taking on a capital partner, or refinancing. Every one of those events requires clean, lender-quality or buyer-quality financials, and someone who can quarterback the process. Walking into a deal without that support is expensive.
A lender, investor, or board asking questions you can't answer. "What does your 13-week cash flow look like?" "What's your adjusted EBITDA?" "Can you walk me through your revenue concentration?" If those questions send you to Google, you need a CFO.
Profitability that doesn't match revenue. You're growing and you're still squeezed. That's almost always a margin, cost structure, or working capital problem — and it doesn't fix itself.
You're making major financial decisions without a financial model. Hiring 10 people, signing a new lease, entering a new market. If your process is "it feels right," the risk is accumulating quietly.

If two or more of these apply to your business right now, you don't need more signs. You need to make a decision.

Pyek Perspective

The clients who get the most out of a fractional CFO engagement are the ones who come in before the crisis, not after. Once you're in a cash squeeze or a deal has gone sideways, the CFO is doing triage. That's fine — we can do triage — but the leverage is in the planning, not the rescue. — Ray DeLaughter, Managing Partner, Pyek Group

What a Fractional CFO Actually Does in the First 90 Days

The first engagement isn't glamorous. It's a financial audit of the business — not a formal audit, but a diagnostic. We look at the chart of accounts, the close process, the reporting package, and the cash flow picture. Usually within 30 days, there are two or three findings that pay for the engagement several times over.

After the diagnostic, the work shifts to building the financial infrastructure the company actually needs: a proper reporting cadence, a rolling cash forecast, and a set of KPIs that connect to how the business operates. None of that is complicated. All of it is consequential.

When You're Not Ready — And That's a Real Answer

Fractional CFO services aren't the right answer for every company. If you're under $3M in revenue and your business model is stable, good accounting and bookkeeping plus a solid CPA relationship is probably sufficient for now. Spend the money on building revenue, not on financial infrastructure you don't yet need.

The readiness test isn't about revenue alone. A $5M company with a pending acquisition, a covenant-heavy credit facility, or a private equity partner has complexity that justifies the investment. A $20M company with a simple model, steady cash flow, and no near-term transactions might not. Complexity and decision frequency matter more than the top line.

Be honest about your situation. Hiring a fractional CFO when you don't need one is wasteful. Not hiring one when you do need one is dangerous.
