Fractional CFO Services: Common Questions

What does a fractional CFO do?

A fractional CFO provides senior financial leadership on a part-time basis — cash flow forecasting, budgeting and variance analysis, KPI reporting, profitability analysis, pricing strategy, lender and financing support, and growth or exit planning. Bookkeeping records what happened; a fractional CFO tells you what to do next. Our full guide covers the seven signs a business needs one.

How much does a fractional CFO cost compared to a full-time CFO?

A full-time CFO in the Maryland market commands a six-figure salary plus benefits and payroll taxes — a cost most businesses under roughly $10 million in revenue can't justify. A fractional engagement delivers the same caliber of financial leadership at a fraction of that, scaled to the hours your business actually needs. See our pricing page for details.

What's the difference between a fractional CFO and an outsourced controller?

A controller focuses on accuracy and control — the monthly close, reconciliations, financial statements, and internal controls. A CFO focuses forward — forecasting, strategy, and the financial decisions that shape where the business goes. Many growing businesses need both, and we provide them together from one Frederick office.

Is my business too small for a fractional CFO?

The threshold isn't a revenue number — it's whether your decisions have become expensive enough that being wrong costs more than the guidance. A contractor deciding whether to buy a building needs this analysis. A sole proprietor with steady work and simple finances usually doesn't. We'll tell you honestly which one you are.

Do I have to move my bookkeeping and taxes to you as well?

No — though there's a real advantage when it's under one roof. Financial strategy and tax strategy inform each other constantly: equipment timing, the Maryland PTE election, S-Corp salary decisions, and choosing between a Solo 401(k) and a SEP-IRA. When the CFO and the tax advisor are the same firm, nothing falls between them.
