The Complete Guide for Founders --- *Everything you need to know about hiring part-time CFO expertise — and whether it’s right for your business.* --- If you’re running a company between $1M and $20M in revenue, you’ve probably felt the gap: your bookkeeper handles the past, your accountant handles compliance, but nobody is managing the financial future of your business. That gap is exactly what a fractional CFO fills. --- ## What Is a Fractional CFO? A fractional CFO is an experienced Chief Financial Officer who works with your company on a part-time or contract basis. Instead of paying a full-time CFO salary — which runs $200,000–$400,000+ per year plus benefits and equity — you get the same level of strategic financial expertise for a fraction of the cost. The “fractional” refers to the time commitment: you might engage a fractional CFO for 10–40 hours per month, depending on the complexity of your business and what you need. That time is spent on the highest-value financial work — strategy, analysis, and decision support — not day-to-day transaction processing. A fractional CFO is not: – A bookkeeper (they don’t record transactions) – A CPA or tax accountant (they don’t prepare tax returns) – A controller (they don’t manage the close process day-to-day) – A financial analyst (they’re more senior and strategic) They work *above* your existing finance function, or they help you build one. --- ## What Does a Fractional CFO Actually Do? The scope varies by engagement, but most fractional CFO work falls into these categories: ### Financial Planning & Analysis (FP&A) Building and maintaining financial models, running scenario analysis, preparing budget-to-actual reports, and translating financial data into decisions. If you’ve ever looked at a P&L and not known what to do with it, this is where a fractional CFO changes everything. ### Cash Flow Management Forecasting cash needs 13–26 weeks out, identifying gaps before they become crises, optimizing the timing of receivables and payables, and building the discipline to never be surprised by a cash shortfall. ### Fundraising Support Preparing investor-ready financial models and projections, building data rooms, working through due diligence with potential investors, and advising on deal structure and valuation. Most founders have never raised money before — a fractional CFO often has done it dozens of times. ### Exit and M&A Preparation Cleaning up financials for a sale, building quality-of-earnings models, normalizing EBITDA with proper add-backs, preparing management presentations, and working alongside your M&A attorney through a transaction process. ### Banking and Debt Managing lender relationships, preparing materials for SBA loans or lines of credit, negotiating covenant structures, and optimizing your capital structure. ### Board and Investor Reporting Building monthly reporting packages, KPI dashboards, and board decks that give investors and advisors a clear view of business performance — and position you as a professional operator. ### Financial Infrastructure Implementing accounting systems, closing processes, internal controls, and reporting frameworks that scale with the business and hold up to investor or buyer scrutiny. --- ## Fractional CFO vs. Controller vs. Bookkeeper These three roles are often confused. Here’s how they differ: | Role | Focus | Typical Cost | When You Need It | | --- | --- | --- | --- | | Bookkeeper | Recording past transactions | $20–$50/hr | From day one | | Controller | Accuracy of financial statements | $60–$120/hr | $1M+ revenue | | Fractional CFO | Financial strategy and future | $150–$350/hr | $1M–$20M revenue | | Full-time CFO | All of the above, full-time | $200K–$400K+/yr | $20M+ or pre-IPO | Most growing companies need all three — but at different stages and at different levels of engagement. A fractional CFO is typically the last piece to be added and the highest-leverage hire when you’re preparing for a significant event (fundraise, exit, rapid growth). --- ## When Do You Need a Fractional CFO? You probably need a fractional CFO if any of these are true: **You’re preparing to raise capital.** Investors expect sophisticated financial models, clean historical financials, and a founder who can speak fluently about unit economics, runway, and valuation. If you can’t do that confidently, a fractional CFO gets you there. **You’re exploring a sale.** A business sale is the most financially complex event most founders ever go through. Having a CFO in your corner who has done it before — not just an attorney — dramatically improves both the process and the outcome. **Cash flow is unpredictable.** If you’re regularly surprised by tight cash months, or you can’t confidently answer “how much cash will I have in 90 days,” you need CFO-level cash flow management. **You’re growing fast and losing visibility.** Rapid growth creates financial complexity. Margins compress. Working capital needs spike. Hiring and capex decisions compound. A fractional CFO keeps you from flying blind. **Your books are a mess.** If your P&L doesn’t match reality, your revenue recognition is inconsistent, or your accountant can’t explain the numbers — you need someone to fix the foundation before you run into trouble with investors, a bank, or a buyer. **You need a thinking partner.** Some of the most valuable fractional CFO work is just having a senior financial mind in the room when you’re making big decisions — pricing a contract, negotiating a lease, evaluating an acquisition, deciding whether to hire. --- ## How Much Does a Fractional CFO Cost? Fractional CFO pricing typically falls into two models: **Hourly:** $150–$350 per hour, depending on experience and market. Common for project-based engagements. **Monthly retainer:** $2,000–$10,000 per month, depending on scope and hours. Most ongoing engagements work this way — you get a defined number of hours per month and a consistent working relationship. For context, a full-time CFO at a $5M revenue company would cost $180,000–$250,000 in salary alone, plus benefits, bonus, and potentially equity. A fractional CFO delivering 20 hours per month at $250/hr costs $5,000/month — $60,000 per year for access to equivalent or greater expertise. The ROI isn’t hard to find. One better financing decision, one avoided cash crisis, or one cleaner exit outcome typically pays for years of fractional CFO fees. --- ## What to Look for in a Fractional CFO Not all fractional CFOs are the same. The right fit depends on your situation: **Industry experience.** A fractional CFO who has worked with SaaS companies will speak a different language than one who specializes in professional services or manufacturing. Ask specifically about companies similar to yours. **Transaction experience.** If you’re heading toward a fundraise or exit, find someone who has been through that process — ideally multiple times, on the operator side. **Technical depth vs. strategic fit.** Some fractional CFOs are excellent at building models and financial infrastructure. Others are better at investor relations and strategic narrative. Know which you need. **References.** Ask to speak with two or three current or former clients. A good fractional CFO will have clients who are enthusiastic advocates. **Communication style.** You’ll be working closely with this person on high-stakes decisions. Make sure you actually trust and respect their judgment — not just their credentials. --- ## Fractional CFO vs. Hiring a Full-Time CFO The decision comes down to stage and need: **Hire fractional when:** You need CFO-level thinking but not CFO-level hours. You’re under $20M in revenue. You’re preparing for a specific event (raise, sale) rather than running a perpetual finance machine. You want flexibility. **Hire full-time when:** You’ve raised significant capital and have investor expectations for a full-time CFO. Your financial complexity genuinely requires 40+ hours per week of dedicated attention. You’re building toward an IPO or very large exit. For most founder-led companies between $1M and $20M, a fractional CFO is the right answer — and often a better one than full-time, because the best fractional CFOs bring pattern recognition from working across many companies simultaneously. --- ## Frequently Asked Questions **How many hours per month does a fractional CFO typically work?** Most engagements range from 10 to 40 hours per month. Early-stage companies or those needing light strategic support might need 10–15 hours. Companies in the middle of a fundraise or sale might need 40+ hours temporarily. **Can a fractional CFO help with QuickBooks or other accounting software?** They can advise on systems and often have strong opinions about what tools to use — but the day-to-day work in accounting software typically belongs to a bookkeeper or controller. The fractional CFO works from the outputs, not the inputs. **Does a fractional CFO replace my CPA?** No. Your CPA handles tax compliance and preparation. A fractional CFO handles financial strategy and planning. The two roles are complementary, and a good fractional CFO will coordinate closely with your accountant. **How long does a fractional CFO engagement typically last?** Many engagements are ongoing — a fractional CFO becomes a long-term member of your team, just part-time. Others are project-based: a 3–6 month engagement to prepare for a fundraise, or a 6–12 month engagement running up to a business sale. **What’s the difference between a fractional CFO and a financial advisor?** A financial advisor manages personal investments. A fractional CFO manages business financial strategy. Completely different role, completely different function. --- ## Ready to Talk to a Fractional CFO?
