A fractional CFO needs an active CPA or CMA plus 8 to 10 years of senior finance experience. A fractional Controller needs a finance or accounting degree plus 5 to 7 years of accounting or audit work. Those are your baselines, and the details beyond them separate a good hire from an expensive one.
You're running a growing business and the financial questions are getting past you. Cash flow forecasting, investor conversations, whether the numbers you're looking at are even right. A fractional CFO or Controller gives you senior finance help part-time, without the full-time salary. The qualification question matters because the wrong hire wastes money and gives you confidence in numbers that might be wrong.
Let's walk through what to actually look for.
CFO credentials: what the paperwork means
An active CPA or CMA tells you the person has passed a rigorous exam and keeps their continuing education current. That's the floor. Above that, you want someone who has spent 8 to 10 years making financial decisions for companies of similar size and complexity to yours. Not bigger. Not smaller. Similar.
Here's why size matters. A CFO who has only worked inside a 500-person manufacturer will look at your three-person electrical shop and overengineer everything. They'll build a 40-tab cash flow model when you need a one-page forecast that tells you whether you can hire that second apprentice next quarter. On the flip side, someone who has only worked with solo consultants won't have the chops to help a food-truck owner opening a second location and needing to model the capital expenditure against projected revenue.
Ask directly: have you worked with companies of similar size and industry before? Then ask for a specific example. If they can describe a real decision they guided, with a real outcome, that's the person. If they talk in generalities about "strategic financial planning," keep looking.
A strong fractional CFO candidate will also have proven experience in cash flow forecasting, strategic planning, and investor relations. Cash flow forecasting is the skill that keeps you from discovering in March that you can't make payroll in April. Strategic planning means they can look at your Savannah-based photography business and tell you whether booking 30 more weddings at your current price point actually improves profit or just burns you out for the same margin. Investor relations matters if you're ever going to raise money, bring on a partner, or apply for an SBA loan. The CFO should be able to speak the lender's language and translate it back to you.
Controller credentials: the accuracy owner
A fractional Controller needs a bachelor's or master's degree in finance, accounting, or business. A CPA or CMA is a bonus here, not a requirement. What's required is 5 to 7 years of experience as an auditor or accountant, ideally followed by time as an assistant Controller.
The Controller's job is to own the accuracy of your monthly close and financial statements. Every transaction in, every transaction out, reconciled and reported correctly. If your Controller is good, your CFO can trust the numbers. If your Controller is bad, your CFO is building strategy on a foundation of sand.
A forecast built on an unreconciled balance sheet is a guess with a spreadsheet around it.
What you want in a Controller candidate is strong experience across four areas: accounting, reporting, systems, and internal controls. Accounting means they know how transactions should be coded and why it matters. Reporting means they can produce a clean income statement and balance sheet that actually match. Systems means they know their way around your accounting software. Internal controls means they can set up processes that catch errors and prevent fraud before they become a problem.
The communication test
This is the qualification people skip and regret skipping. Ask both candidates, CFO and Controller, how they communicate financial insights to non-accountants.
Understanding complex financial concepts is one thing. Explaining them to a barber who is busy running a shop and doesn't have time to decode a balance sheet is something else entirely. Your fractional finance hire needs to sit across from you and say, "Your product margin dropped because the cost of shears and supplies went up 12% last quarter. You need to raise your cut price by $3 or cut supply costs, or you'll be working for less per hour than your junior stylists by summer."
If a candidate starts throwing around terms like "EBITDA compression" and "working capital optimization" without translating, that's a red flag. You're hiring a financial partner, not a textbook narrator.
You need someone who can explain the surplus. If the interview feels like that scene, move on.
What it costs and why fractional makes sense
A fractional CFO engagement typically runs $3,000 to $10,000 per month. A full-time CFO salary averages $438,118 per year. That's salary alone, before benefits, bonuses, and overhead.
Fractional means you pay for the hours you actually need. A food-truck owner doing $400,000 in annual revenue probably needs a CFO for 10 to 15 hours a month. That's the low end of the range. A construction firm bidding on multi-phase commercial contracts might need 30 to 40 hours. That's the high end. You scale up or down as the business demands it.
A fractional Controller follows the same logic. You don't need a full-time Controller if your monthly close takes someone two days and the rest of the month is light. You pay for the work, not the seat.
Which one do you need first?
Here's the decision point that saves people the most money. If your monthly close takes more than ten business days, or if your numbers change after you've already reported them, hire the Controller first.
This is the trap. Hiring a CFO to fix bookkeeping problems means you're paying strategy rates for reconciliation work. You would not hire an architect to hammer nails. Don't hire a CFO to fix a messy chart of accounts.
The symptom is simple. You get your monthly numbers on the 18th. Three days later, your bookkeeper finds a duplicate entry. The numbers shift. You've already made a decision based on the old ones. That's a Controller problem disguised as a CFO problem.
If you can trust the numbers but you can't forecast cash, can't answer a lender's questions, or can't model a pricing change, then hire the CFO first. Your books are solid. Your strategy is what's missing.
Some businesses need both roles at the same time. The right structure depends on the complexity of your accounting function, the quality of your existing reporting, and the financial decisions you need to make in the next 12 months. This is exactly the kind of judgment call where getting it wrong costs real money. It's the work Nomadica does for clients. We look at your books, your close process, and your goals, and tell you which hire actually moves the needle.
Five questions to ask before signing anything
Before you hire either role, get answers to these five questions.
Have you worked with companies of similar size and industry? A CFO who has only worked in SaaS will not intuitively understand the cash cycle of a landscaping business. A Controller who has only worked in retail may not know the nuances of job costing for a contractor.
Are you familiar with my accounting software? If you're on QuickBooks and they only know Sage, you're paying them to learn a system on your dime. Ask for specific software names and versions.
How do you communicate financial insights to non-accountants? This is the test from earlier. The answer should sound like a person talking, not a slide deck.
What does your availability look like, and how quickly can you respond to urgent matters? A fractional CFO juggling 12 clients may not be able to drop everything when your lender needs updated projections by Friday. Know the response time before you need it.
How can you adapt your services as my business grows or my needs change? The whole point of fractional is flexibility. If the answer is rigid, you're not getting the model you're paying for.
A note on titles
You'll see the terms fractional, outsourced, interim, and virtual used interchangeably. They don't mean the same thing. Fractional means ongoing part-time. Outsourced means the function sits with an outside firm. Interim means temporary, usually near full-time, to cover a gap. Virtual just means remote. For most small business owners, the practical choice is fractional versus full-time. Don't get distracted by the rest.
