Fractional CFO Engagements: How They Are Structured and How They Change as You Scale Past $10M

At the end of the quarter, hold a review that covers progress, surprises and changes to scope. Record the outcomes in a short memo that both sides sign off.

Handling disagreement between the executive and the owner

Disagreements are normal and can be productive. A senior finance executive may recommend slowing a hiring plan, tightening credit terms or declining a contract that the owner favours. Decide in advance how to handle such moments.

• The executive presents the analysis, the assumptions and the alternatives in writing.
• The owner asks questions and shares information the executive may lack.
• If the owner proceeds against the advice, the decision and the reasoning are recorded.
• The executive continues to support the decision professionally, unless it would require acting unlawfully or misreporting.

A professional will state limits plainly. They will not record entries they believe are wrong or sign statements they believe are misleading. Agreeing on this principle at the start protects both sides.

Exit from the engagement

Plan for the end as carefully as the start. Provide the notice required, collect all documentation, review open items and confirm access removal. Ask for a final memo that summarizes the state of the finance function, outstanding issues and recommendations. Keep the relationship cordial. A former executive who understands your business can be a useful adviser later, and a clean exit leaves the way open for a future return if your needs change.

Engagement design: your questions answered

How many hours per month does a fractional CFO engagement usually involve?

It varies with scope, complexity and cadence, from a few hours for light advisory to several days a month for hands-on leadership. Focus on deliverables and decisions rather than hours alone. Agree on an estimate, a cap or a review point so that cost and workload stay aligned.

Can a fractional CFO lead my finance team?

Yes, within the authority and hours agreed. Many executives supervise controllers and analysts, set priorities and review work, while staff handle daily tasks. Make reporting lines clear, and recognize that limited hours mean the executive depends on a capable team to execute.

When should we convert to a full-time CFO?

Consider it when the workload regularly exceeds a half-time load, when complexity such as multiple entities or frequent financings requires daily presence, or when board and investor expectations call for a dedicated executive. No revenue figure forces the decision, so judge by workload and risk.

How do engagements change as revenue passes $10 million?

The role tends to shift from producing reports to directing a team, designing controls, managing capital and supporting governance. Scope expands to include board reporting, financing, systems and risk. Revenue is only a rough guide, and industry and complexity matter more.

Should the fractional CFO be paid a fixed retainer or by the hour?

A fixed retainer suits ongoing work with defined deliverables, while hourly rates suit uncertain or occasional needs. Hybrids are common. Whichever you choose, require clarity on what is included, how extras are billed and when the arrangement is reviewed.

What conflicts of interest should I ask about?

Ask about other clients that compete with or deal with your company, referral fees or commissions from lenders or software vendors, and any financial interest in deals the executive recommends. Require written disclosure and agree on how confidential information will be protected.

What happens if my fractional CFO becomes unavailable?

A good provider has a backup plan, such as another qualified person at the firm, plus documentation and shared access so work can continue. Ask about continuity before signing, and keep key models and files in company-owned systems.
