How to Evaluate the Cost of CFO Advisory

“How much does CFO advisory cost?” is a question companies may ask when they first consider the service. A price comparison on its own is misleading, however. An outside CFO who works two days a month and a finance executive who is on site two days a week and joins bank meetings naturally cost different amounts. This article gives no prices. It explains what to look at when assessing a proposal and how to compare cost with value.

What drives the cost

Factor	Question	Effect on cost
Working intensity	How many days or hours a month? Is attendance at meetings included?	The most direct driver
Scope	Reporting, budgeting, bank relationships or team development?	A wider scope needs more experience and time
Deliverables	Which reports, models and process documents will be delivered?	Written deliverables clarify expectations and assessment
Duration	A defined project or ongoing support?	Total fee matters for projects; monthly fee for ongoing work
State of the company’s data	Are the accounting records up to date and reliable?	Data clean-up lengthens the start-up period
Complexity	Group companies, currency positions, many banks	Increases the analysis and coordination load

Fee structures

Three basic structures are used in practice:

• Fixed monthly fee: Suits a defined number of days and regular deliverables. Easy to budget. The contract should state what happens if the days are exceeded.
• Project fee: Suits work with a clear start and end, such as setting up a budget, a financial model or preparation for a bank meeting. Define in advance when the project counts as finished.
• Hybrid: An intensive set-up project at the start, followed by lower-intensity monthly support.

Whichever structure is chosen, the working time and outputs that the fee pays for should be written down.

The right comparison: total cost and benefit

The advisory fee should not be compared only with the salary of a full-time finance executive. The total cost of full-time employment also includes the employer’s statutory obligations, benefits, the recruitment process, the time it takes the person to become effective and the cost of a possible wrong hire. On the other hand, outside support carries the risk that knowledge which should build up inside the company stays outside it. The comparison should therefore run both ways: the question is not which model is cheaper, but which model meets the company’s current need with less risk. For the decision criteria, see fractional versus full-time CFO.

To measure the benefit, write down a baseline at the start. Example indicators:

• the working day on which the monthly close and report are ready,
• how many weeks ahead the cash forecast looks, and its variance from actuals,
• how often budget and actuals are compared,
• the collection period and the amount of overdue receivables,
• how orderly the financial information given to banks is.

Changes in these indicators make it possible to discuss the value of the support in numbers. No advisory work can guarantee results, but if the indicators to be tracked are written down at the start, the assessment does not come down to personal impressions.

Checklist for reading a proposal

1. Is the scope written down? Specific tasks and deliverables rather than general wording such as “financial management support”.
2. Is the working rhythm defined? Which days, which meetings, which response times.
3. Who will do the work? Is the person presenting the proposal the person who will do the work?
4. Is there a knowledge transfer plan? Models, templates and processes set up should stay with the company, documented.
5. How are confidentiality and data access handled?
6. Are the exit terms and notice period clear?
7. How is additional work priced?

Common mistakes

• Choosing the lowest proposal without reading the scope: If days and deliverables differ, the proposals are not comparable.
• Not defining success: Without baseline indicators, the question “did it help?” goes unanswered a few months later.
• Seeking support only in a crisis: Once a cash squeeze has started, options narrow and costs may rise.
• Leaving knowledge transfer to the end: Transfer should be planned from the start of the engagement.

What it means for management

The cost of CFO advisory pays for time and outputs. The right question is not “how much?” but “for this fee, which tasks will be done, at what rhythm and with which measurable outputs?”. Work with a written scope, indicators defined at the start and planned knowledge transfer makes the fee possible to assess objectively. For how the first period can be structured, see the first 90 days of CFO support.
