What Is a Fractional CFO? A Guide for $1M–$10M Businesses

What is a fractional CFO? Learn how part-time CFO services work, what they cost, and when $1M–$10M businesses should hire one.

What Is a Fractional CFO?

A fractional CFO is a senior finance executive who works with a company on a part-time, contracted, or project basis rather than as a full-time employee. You get the same strategic financial leadership a full-time CFO would provide — board-ready reporting, cash forecasting, capital planning, lender and investor communication — but at a fraction of the cost and only for the hours you actually need.

For businesses in the $1M–$10M revenue range — the sweet spot CorpFinance.org serves — the fractional model usually beats both alternatives: hiring a full-time CFO (too expensive, too underutilized) and trying to stretch a bookkeeper or controller into strategic decisions they aren't trained for.

Fractional CFO vs. full-time CFO vs. controller

These three roles are routinely confused. They are not interchangeable.

Role What they own Typical annual cost (US)
Bookkeeper Day-to-day transactions, AP/AR entry, bank reconciliations $40K–$70K
Controller Month-end close, GAAP compliance, internal controls, financial statements $90K–$160K
Full-time CFO Strategy, forecasting, capital structure, M&A, board and investor relations $200K–$400K + bonus + equity
Fractional CFO Same scope as full-time CFO, scaled to your hours $3K–$15K / month

A controller looks backward — making sure the books are accurate and closed on time. A CFO looks forward — turning those numbers into decisions about pricing, hiring, expansion, debt, and ownership. Below roughly $10M in revenue, most companies don't have enough forward-looking work to keep a full-time CFO busy. That's the gap fractional fills.

What a fractional CFO actually does

The deliverables vary by engagement, but a typical CorpFinance.org fractional engagement covers some combination of:

  • Monthly financial reporting — a clean P&L, balance sheet, and cash flow with written commentary the owner can hand straight to a board, a banker, or an investor.
  • 13-week cash forecast — the single most useful tool for any business under $10M. Knowing exactly when cash gets tight prevents 90% of avoidable crises.
  • Annual budget and operating plan — built bottom-up with department owners, then defended monthly through variance review.
  • Pricing and unit economics — what does it actually cost to serve one customer, fill one cover, or deliver one job? Most owner-operated businesses are mispricing at least one product or service.
  • Capital planning — when to take on debt, when to raise equity, when to defer capex, and how to model the impact of each.
  • Lender and investor communication — covenant tracking, lender updates, investor reporting packages, and the diligence support that comes with any refinance, raise, or sale.
  • Systems and team coaching — leveling up your existing controller or bookkeeper so the in-house team gets stronger over time, not more dependent.

When does a fractional CFO pay off?

The model works best in five situations:

  1. You're between $1M and $10M in revenue. Below $1M, a strong bookkeeper plus a quarterly advisory check-in is usually enough. Above $10M, the workload starts justifying a full-time hire.
  2. You're growing fast. Growth surfaces every weakness in a finance function — cash gaps, margin compression, broken pricing. A fractional CFO sees these early.
  3. You're preparing for a transaction. Refinance, recapitalization, acquisition, or sale — buyers and lenders want to talk to a CFO, not a bookkeeper, and the diligence prep alone usually justifies the fee.
  4. You're losing money and don't know why. A fractional CFO can typically diagnose the root cause in 30–60 days and build the plan to fix it.
  5. Your industry has unusual economics. Restaurants, hotels, private clubs, and other hospitality businesses run on prime cost, occupancy, and dues mechanics that a generalist CFO doesn't know. Industry-specific fractional firms like CorpFinance.org bring that fluency on day one.

What does a fractional CFO cost?

Most US fractional CFO engagements fall between $3,000 and $15,000 per month, depending on hours and scope. A typical $1M–$10M company spends $5,000–$8,000 per month for ongoing strategic support, monthly board-ready reporting, and on-call availability for major decisions.

Compare that to the loaded cost of a full-time CFO — base salary, bonus, benefits, payroll taxes, equity, and the recruiter fee to hire one — which routinely lands above $300,000 per year. For companies that don't yet have 40 hours a week of CFO-level work, the math is decisive.

What to look for in a fractional CFO

Not all fractional CFOs are equal. Before signing an engagement, ask:

  • Have they actually been a CFO? Career consultants who skipped the operator seat tend to produce decks instead of decisions.
  • Do they know your industry? A restaurant CFO and a SaaS CFO are not interchangeable. Industry depth shortens the learning curve from months to days.
  • What does success look like in 90 days? A real fractional CFO can describe the first three deliverables before the contract is signed.
  • Who does the work? Some firms sell the senior partner and then hand the file to a junior. Confirm who is actually in the seat.
  • What happens if you outgrow them? A good fractional CFO will tell you when it's time to hire full-time and help you do it.
