Fractional CFO

When Does a Small Business Need a Fractional CFO?

Bookkeepers record. Accountants close and report. CPAs file. None of them help you make the next decision. That's what a CFO does.

A CFO turns numbers into decisions. Bookkeeping records what happened; accounting summarizes it; tax files for it. CFO work is forward-looking.
Core CFO outputs: 12–18 month forecast, 13-week cash flow, KPI dashboard, owner/board reporting, pricing and margin analysis, capital structure recommendations.
A CFO is also the chief negotiator with banks, investors, buyers, and major vendors — using your numbers as leverage.
Fractional means you get this output without paying $250K+/year for a full-time hire. Typical fractional engagement: 5–20 hours/month.

You crossed $1M+ in revenue with no formal forecast or budget that's actually used.
You're hiring 5+ people in the next 12 months and can't model the cash impact.
You're considering a major decision: opening a location, raising debt, taking on a partner, selling the business.
Your books say you're profitable but the bank account doesn't agree — you need someone to explain the gap.
You're spending more than 5 hours a week yourself on financial questions that aren't core to running the business.

You're about to take on a bank loan or SBA loan and need a presentable financial package.
You're considering selling — buyers want clean GAAP financials, normalized EBITDA, customer concentration analysis.
You want to introduce equity comp, profit sharing, or partnership buyouts and need to model the cash impact.
You're approaching a tax election (S-corp, QSBS, Section 1202) and want CFO-level input alongside CPA advice.
You're losing money and need a recovery plan — not just a P&L showing the losses.

Discovery: 30–60 days of getting deep on the business — books, contracts, customers, costs, cash position, runway.
Outputs: monthly close meeting with KPI review, quarterly forecast refresh, 13-week cash forecast updated weekly, owner/board package monthly.
Deliverables that compound: a budget you actually use, a forecast that gets revisited, a KPI dashboard that drives decisions.
Cost: typically $3K–$8K/month for a small-to-mid business. Compared to $250K+/year for a full-time CFO, the math is obvious.

Not a bookkeeper or controller — a CFO doesn't reconcile bank accounts (but works with someone who does).
Not a tax preparer — a CFO works alongside a CPA, not instead of one.
Not a banker or fundraiser — a CFO prepares you to talk to bankers and investors and runs the process, but doesn't replace those relationships.
Not a quick fix — meaningful CFO impact takes 90–180 days to show up in better decisions and reporting.
Considering one? Rubric Financial offers fractional CFO support starting at a fixed monthly fee.
