What Does a Fractional CFO Actually Do? Why Sioux Falls Small Businesses Are Hiring One Instead of a Full-Time Finance Person (From Lang Tax Solutions)

Your business has grown past the stage where you can manage the finances from a spreadsheet and a gut feeling. Revenue is up, but you’re not sure where the profit is going. You want to hire another employee but can’t tell if the cash flow supports it. You’re thinking about a loan or a line of credit but don’t have projections to show the bank. You need financial leadership, but hiring a full-time CFO at $150,000 or more in salary isn’t realistic for a company your size. This is the gap that fractional CFO services fill, and it’s why Lang Tax Solutions has made it a core offering for small businesses in the Sioux Falls area and beyond. A fractional CFO gives you the financial strategy and decision-making support of a senior finance executive for a fraction of the cost, scaled to the hours and scope your business actually needs.
The Difference Between a Bookkeeper, a CPA, and a CFO
Most small business owners have a bookkeeper or an accountant. Some have both. What they often don’t have is someone who translates financial data into business decisions. Understanding the distinction between these roles clarifies why a fractional CFO fills a need that your existing financial team doesn’t.
A bookkeeper records transactions. They categorize income and expenses, reconcile bank statements, and keep your books accurate and current. They tell you what happened with your money.
A CPA prepares tax returns, ensures compliance with tax law, and advises on tax strategy. They tell you what you owe and how to minimize it.
A CFO looks forward. They take the financial data your bookkeeper maintains and the tax position your CPA manages and use it to answer the questions that actually drive your business: Can we afford to hire two people this quarter? What happens to cash flow if our largest client pays 60 days late instead of 30? Should we lease or buy that equipment? What revenue target do we need to hit before opening a second location? How do we structure this deal so it doesn’t create a tax problem next year?
Those questions require someone who understands financial modeling, cash flow forecasting, scenario planning, and how operational decisions ripple through the numbers. A bookkeeper isn’t trained for it. A CPA is focused on compliance and tax optimization. The CFO is the person who connects the financial picture to the business strategy.
What a Fractional CFO Does in Practice
The word “fractional” simply means part-time. Instead of sitting in your office five days a week at a six-figure salary, a fractional CFO works with your business on a scheduled basis, typically a set number of hours per week or month. The engagement is built around the specific financial leadership your business needs at its current stage.
For a Sioux Falls business doing $500,000 to $3 million in annual revenue, a fractional CFO engagement might include monthly financial reviews where the CFO walks you through your income statement, balance sheet, and cash flow statement, explaining what the numbers mean for your operations and where the trends are heading. Not just “revenue was up 8 percent” but “revenue was up 8 percent and your margins dropped 3 points because material costs increased faster than your pricing, and if that continues for two more quarters, your net income will be flat despite the growth.”
Cash flow forecasting is one of the most immediately valuable things a fractional CFO provides. Many profitable businesses run into cash crunches because the timing of receivables and payables doesn’t align. A 13-week cash flow forecast shows you exactly when cash gets tight and gives you time to prepare, whether that means accelerating collections, delaying a non-critical purchase, or arranging a short-term line of credit before you need it urgently.
Budgeting and forecasting go hand in hand with cash flow work. A fractional CFO helps you build a realistic annual budget based on historical data and growth assumptions, then updates the forecast quarterly as actual results come in. This rolling forecast becomes the financial framework your business decisions rest on. Should you invest in that new piece of equipment? The forecast tells you whether the cash flow supports it and when the investment breaks even.
When you need to talk to a bank, a fractional CFO prepares the financial package. Banks want to see organized financial statements, projections that make sense, and evidence that someone is managing the numbers thoughtfully. A loan application backed by a CFO-prepared financial package gets taken more seriously than a stack of QuickBooks printouts.
Why This Model Works for Sioux Falls Businesses Specifically
Sioux Falls has a strong and growing small business community, but the market isn’t structured like a major metro where companies can easily recruit full-time finance talent. A full-time CFO in Sioux Falls commands a salary north of $120,000 to $150,000 before benefits. For a business doing $1 million in revenue, that’s 12 to 15 percent of gross revenue allocated to a single overhead position. The math doesn’t work.
A fractional CFO engagement with Lang Tax Solutions costs a fraction of that annual salary because you’re paying for the specific hours and expertise your business uses, not for a full-time seat. A business that needs 10 hours of CFO-level work per month gets exactly that, with the same quality of financial analysis and strategic guidance a full-time hire would provide.
The other advantage of the fractional model in a market like Sioux Falls is breadth of experience. A full-time CFO at one company sees the financial challenges of one business in one industry. A fractional CFO working across multiple businesses sees patterns and solutions across industries, company sizes, and growth stages. That cross-pollination of insight benefits every client because the CFO brings lessons learned from one engagement into another.
Signs Your Business Has Outgrown Its Current Financial Setup
There’s a stage in a business’s growth where the owner starts making financial decisions based on the bank balance rather than actual financial analysis. You check the account, see a number that feels comfortable, and approve a purchase. Or you see a number that feels low and delay a hire you need. That’s the clearest sign you need CFO-level support.
Other indicators: you’re profitable on paper but always seem short on cash. You don’t know your gross margin by product or service line. You can’t answer the question “what would happen to our bottom line if we raised prices 5 percent?” without guessing. Your bookkeeper keeps the records clean but can’t help you interpret them. Your CPA does a great job at tax time but isn’t involved in your day-to-day financial decisions. You’re preparing for a significant change, a new location, a major hire, a partnership, a loan, an acquisition, and you don’t have a financial model to evaluate the decision.
Any of these situations means you’ve reached the point where financial data alone isn’t enough. You need financial analysis, and that’s what a CFO provides.
How Lang Tax Solutions Structures Fractional CFO Engagements
Lang Tax Solutions approaches fractional CFO work as an extension of the accounting and tax services they already provide to small businesses. For clients who already use Lang for bookkeeping and tax preparation, the fractional CFO layer adds the strategic interpretation and forward-looking analysis that turns historical data into actionable business intelligence.
The engagement starts with a financial assessment: where your books stand, what your current reporting looks like, and what questions you need answered. From there, Jeff and the team build a service plan that covers the specific deliverables your business needs, whether that’s monthly financial reviews, cash flow forecasting, budget creation, bank-ready financial packages, or strategic planning for a major decision.
Because Lang already handles bookkeeping and tax for many of their fractional CFO clients, the financial data flows seamlessly between services. The CFO work is built on books that Lang maintains and tax strategy that Lang manages. There’s no gap between the person keeping your records, the person filing your return, and the person advising your business decisions. It’s one team with a complete picture.
