Step 1: Define What You Actually Need

Before you start searching, get clear on what you're trying to solve. "We need a CFO" is too vague. Different fractional CFOs have different strengths, and matching your needs to their expertise is crucial.

Common Reasons Businesses Hire Fractional CFOs

Fundraising Preparation

You're preparing to raise capital and need investor-ready financials, models, and data room organization.

Strategic Decision Support

You face major decisions—pricing changes, market expansion, acquisitions—and need financial analysis.

Board & Investor Reporting

Your board or investors expect professional financial reporting and you're struggling to deliver.

Financial Infrastructure

You've outgrown your current financial systems and need someone to build proper processes.

Questions to Answer Before Searching

What specific problems need solving? List your top 3-5 financial pain points.
What decisions are you struggling to make? These reveal where you need strategic input.
What's your timeline? Immediate needs (fundraise in 60 days) vs. building for the long term.
How many hours per week do you need? Be realistic about the scope of work.
What's your budget? Fractional CFOs typically cost $3,000-$12,000/month.
Do you have supporting staff? A bookkeeper in place vs. needing full finance function.

Common Mistake

Don't hire a fractional CFO to do bookkeeping. If your books are a mess, fix that first with a bookkeeper or accounting firm. A fractional CFO adds value by analyzing and strategizing with clean data, not by doing data entry.

Step 2: Know Where to Look

Fractional CFOs come from several channels, each with different characteristics.

Referrals from Your Network

Ask other business owners, your attorney, CPA, or investors for recommendations. Referrals often yield the best candidates because someone you trust has vetted them.

Best for: Finding trusted, proven professionals

Fractional CFO Firms

Companies like Eagle Rock CFO specialize in providing fractional finance services. Firms offer vetted professionals, backup coverage, and often integrated services.

Best for: Full-service needs, backup coverage, integrated bookkeeping

LinkedIn and Online Platforms

LinkedIn is full of fractional CFOs. Search for "fractional CFO" plus your industry or location. Platforms like Toptal and CFO Share also match companies with CFOs.

Best for: Wide selection, specific expertise requirements

CPA Firm Referrals

Your accounting firm often knows fractional CFOs who work with similar clients. They can recommend people they've successfully collaborated with.

Best for: Ensuring good fit with your existing accounting setup

How Many Candidates to Evaluate

Plan to have substantive conversations with 3-5 candidates. Fewer than three limits your ability to compare; more than five creates decision fatigue. Initial screening calls (15-20 minutes) can help you narrow a longer list.

Step 3: Evaluate Candidates Thoroughly

Once you've identified candidates, it's time to evaluate them systematically. For detailed interview guidance, see Questions to Ask a Fractional CFO Before Hiring.

Pro Tip: The Problem-Solving Test

During interviews, present a real financial challenge you're facing and ask how they'd approach it. Their answer reveals more than any resume. Look for structured thinking, relevant questions, and practical recommendations.

Step 4: Watch for Red Flags

Some warning signs should give you pause. For a comprehensive list, see Fractional CFO Red Flags.

Can't provide relevant references
Promises results without understanding your situation

Step 5: Structure the Engagement

Once you've selected a candidate, it's time to define the engagement structure. For detailed guidance, see How to Scope a Fractional CFO Engagement.

Key Elements to Define

Scope of Work

Specific deliverables expected
Ongoing responsibilities
What's explicitly out of scope
How scope changes will be handled

Time & Availability

Expected hours per week/month
Regular meeting cadence
Response time expectations
Availability for urgent matters

Pricing & Terms

Monthly retainer amount
What's included vs. additional
Payment terms
Termination notice period

Working Relationship

Primary point of contact
Communication channels
Access to systems and information
Relationship with other team members

Common Engagement Models

Monthly Retainer (Most Common)

Fixed monthly fee for a defined scope of work and hours. Provides predictable costs and committed time from your CFO.

Typical range: $3,000-$12,000/month for 5-20 hours/week

Project-Based

Fixed fee for specific projects like fundraising preparation or system implementation. Good for defined, time-limited needs.

Typical range: $10,000-$50,000 per project

Hybrid Model

Lower base retainer for ongoing support plus project fees for intensive work like fundraising. Balances ongoing access with focused project support.

Example: $2,000/month base + $15,000 fundraising project fee

Step 6: Set Up for Success

The first 30-90 days set the tone for the entire engagement. For a detailed guide, see Fractional CFO Onboarding Checklist.

Before They Start

Preparation Checklist

Grant access to accounting software

Share read-only access to bank accounts

Compile historical financial statements

Gather existing financial models and forecasts

List key contracts and commitments

Introduce them to your bookkeeper/accountant

The First 90 Days

Days 1-30: Assessment

Your fractional CFO reviews your current financial state, identifies gaps, and develops a prioritized improvement roadmap. Expect lots of questions.

Days 31-60: Quick Wins

Implementation of immediate improvements—fixing reporting issues, establishing regular cadences, addressing urgent problems. You should see tangible progress.

Days 61-90: Strategic Foundation

Building longer-term infrastructure—financial models, board reporting templates, forecasting processes. The engagement settles into a sustainable rhythm.

Success Metric

By day 90, you should feel confident about your financial position, have clear visibility into key metrics, and be making better-informed decisions. If you don't feel significantly better about your finances, something isn't working.

Knowing When It's Not Working

Not every engagement works out. If things aren't going well, it's better to address issues early or move on. For guidance on difficult situations, see When to Fire Your Fractional CFO.

Signs the Engagement Isn't Working

You still feel confused about your finances after 60+ days
Communication is consistently slow or unclear
Deliverables are late or low quality
They're not proactive—you have to drive everything
They focus on what you asked for but miss obvious issues
You dread your regular meetings

If you see these signs, have a direct conversation first. Sometimes expectations need realignment. But if issues persist after that conversation, it may be time to transition to someone else. Month-to-month arrangements exist for this reason.

Frequently Asked Questions

How long does it take to hire a fractional CFO?

Most companies can complete the hiring process in 2-4 weeks. This includes defining your needs (1 week), sourcing and initial screening (1 week), and final interviews and negotiation (1-2 weeks). Rushing the process often leads to poor fits, so allow adequate time for evaluation.

Should I hire an individual or a fractional CFO firm?

Both models work well. Individual fractional CFOs often provide more personalized attention and flexibility. Firms offer backup coverage, broader expertise, and sometimes integrated bookkeeping services. Choose based on your specific needs—if you want a single trusted advisor, go individual; if you need a full finance team, consider a firm.

What should I look for in a fractional CFO contract?

Key contract elements include: clear scope of work, hours per week/month, monthly retainer amount, notice period for termination (typically 30 days), confidentiality provisions, and expectations around availability and response times. Avoid long-term lock-ins—month-to-month arrangements are standard.

How do I know if a fractional CFO is the right level for my business?

If you primarily need help with bookkeeping, monthly close, and basic reporting, you may only need a controller or senior bookkeeper. A fractional CFO is right when you need strategic advice, investor relations, fundraising support, or help making major financial decisions. Most $3M-$30M businesses benefit from CFO-level thinking.

Can a fractional CFO work remotely?

Yes, most fractional CFOs work remotely. Cloud-based accounting software, video conferencing, and collaboration tools make remote financial leadership highly effective. Many fractional CFOs never meet their clients in person. However, some companies prefer occasional on-site visits for board meetings or strategic planning sessions.
