Most owners hire accounting help to answer a question about last month. A fractional CFO exists to answer questions about next quarter and next year. Lang Tax Solutions sees the difference show up in the same pattern again and again: a business with clean books, a profitable P&L, and no cash in the account, unsure which of those three facts to believe. Sorting that out is not bookkeeping work. It is the job of someone who can connect the financial statements to decisions about pricing, hiring, debt, and timing.
What does a fractional CFO actually do?
A fractional CFO is a senior finance executive who works with a company part-time, usually on a monthly retainer covering somewhere between 10 and 40 hours. The role is forward-looking. Instead of recording what happened, the CFO builds the models that determine what should happen next.
Typical scope includes cash flow forecasting, budget versus actual review, pricing and margin analysis, lender and investor reporting, and preparation for a financing round or a sale. On a practical level, that often starts with a rolling 13-week cash flow forecast, which projects weekly cash in and out over the next quarter. It is the single most useful tool for a business that is profitable on paper and tight on cash, because it isolates the timing problem from the profitability problem.
How is that different from a bookkeeper or a controller?
The three roles sit at different points on the same timeline. A bookkeeper records transactions and keeps the ledger accurate. A controller owns the monthly close, internal controls, and financial reporting, making sure the numbers are right and arrive on schedule. A CFO takes those finished numbers and uses them to allocate capital.
A useful test: if the question is “what did we spend on payroll in March,” that is a bookkeeping question. If it is “why did our close take 22 days and can we get it to eight,” that is a controller question. If it is “should we take the equipment loan or lease, and what does either do to our debt service coverage,” that is a CFO question. Businesses often try to solve the third by hiring more of the first, which is why they stay stuck.
What does a fractional CFO cost compared to hiring one full time?
Fractional engagements commonly run in the $3,000 to $10,000 per month range depending on scope and company size, while a full-time CFO in most markets carries total compensation well into the low-to-mid six figures once bonus and benefits are included. Verify both figures against your own market, since compensation data varies widely by region and industry.
The cost comparison is not the whole argument. A company doing $3 million in revenue rarely has 40 hours a week of genuine CFO work. It has perhaps eight, concentrated around the monthly close, the forecast update, and whatever decision is live that month. Paying for a full seat means paying for idle senior capacity, or worse, watching a strong hire drift into controller work out of boredom.
Which numbers change first when a CFO gets involved?
Working capital usually moves before profit does, because it responds to process rather than to sales. Days sales outstanding is the standard measure, calculated as accounts receivable divided by revenue, multiplied by the number of days in the period. It tells you how long your customers take to pay.
Pulling DSO from 55 days to 40 on $3 million in revenue frees roughly $123,000 in cash without selling anything additional. That comes from tightening terms, invoicing the day work completes instead of at month end, and following up on aging receivables on a schedule rather than when someone remembers. The same logic runs on the payables side, where paying earlier than terms require quietly funds your vendors’ working capital with your own.
Margin analysis is the second lever. Blended gross margin hides the fact that some customers or product lines are unprofitable. Breaking margin out by segment frequently reveals that a meaningful share of revenue is costing money to service, and that repricing or exiting it improves cash and workload simultaneously.
How does Lang Tax Solutions approach fractional CFO work?
Lang Tax Solutions builds the tax position and the financial strategy as one piece of work rather than two. That matters because most growth decisions carry a tax consequence that is easy to miss in a purely operational analysis. Entity structure affects how owner compensation is taxed. Equipment purchases interact with depreciation elections. Businesses with product or process development work may qualify for the research credit under Section 41, and recent federal legislation restored the immediate deduction of domestic research expenses that had been required to be capitalized since 2022. Confirm current treatment with your tax advisor, as this area has changed repeatedly.
The engagement generally begins with a diagnostic: a review of the last 12 to 24 months of financials, a close-process assessment, and a cash forecast. That output tells you whether you need a CFO, a better controller, or simply a cleaner chart of accounts. Not every business needs the full role, and saying so early saves everyone money.
Growth stalls more often from unclear numbers than from a lack of effort. If you are making decisions on a P&L you do not fully trust, or you cannot say which customers actually earn you money, that is the point to bring in senior financial help. Reach out to Lang Tax Solutions for a financial diagnostic and a straight answer about what your business needs.
