Situations for the Deployment of an Interim CFO

An interim CFO is a temporary finance executive who supports companies in transitional, crisis, or transformation situations. The objective is to ensure leadership strength, financial stability, and a clear basis for decision-making in the short term.

Our project experience shows that companies particularly turn to interim CFOs when time pressure, uncertainty, or strategic changes require immediate, effective financial leadership:

• Transition between two CFOs: The most common case; the previous CFO leaves the company suddenly or unexpectedly
• Growth or transformation: Significant changes within the company
• M&A transactions: During acquisitions or divestments (especially in private equity portfolio companies)
• Restructuring: Capacity constraints exist and specialized expertise is required
• Preparation for financing

The typical duration of an interim CFO engagement is 6–12 months.

An interim CFO faces a wide range of challenges

Interim CFOs typically operate in situations characterized by high dynamics, limited time, and significant responsibility for results:

• (Very) short onboarding period: Rapid assessments and results are required
• High expectation pressure: Typically deployed in time-critical special situations
• Lack of organizational anchoring: The external role requires building trust quickly, often without political backing. There is frequently internal resistance to both the deployment and the requirements of the interim CFO
• Change management: Interim CFOs usually operate in highly dynamic environments involving evolving processes
• Stakeholder management: An interim CFO deals with many unfamiliar internal and external stakeholders
• Unclear starting situation: Especially in crisis mandates, transparency on the current situation is often limited
• Balancing short- and long-term decisions: The role is temporary, but decisions have long-term impact

Our project experience shows that successful interim CFOs combine analytical speed with strong leadership and a high level of execution focus.

Requirements for Interim CFOs:

Professional Requirements – Hard Skills

• Broad finance expertise:An interim CFO must master the entire finance function (planning, reporting, liquidity management, etc.)
• Experience at CFO or senior finance leadership level
• Experience with special situations/projects, e.g., refinancing or M&A transactions
• Strategic understanding, including business models, investment decisions, and strategic risks

Personal Requirements – Soft Skills

• Rapid comprehension: Typically only a few days of onboarding with immediate assumption of responsibility
• Strong execution capability: Interim CFOs are primarily brought in to deliver results
• Leadership and communication skills: Clear communication, persuasiveness, and the ability to manage conflicts are essential for effective stakeholder management
• Independence and objectivity: Due to their external position, interim CFOs can more easily make difficult decisions, drive change, and address politically sensitive topics

Our project experience shows that the success of an interim CFO depends more on leadership and execution capability than on purely technical expertise.

Common mistakes in the selection and engagement of an interim CFO

• Overemphasis on technical expertise: However, the success of an interim CFO primarily depends on leadership capability, ability to drive change, and crisis experience.
• Mismatch of skill set to the situation: The CFO’s experience must align with the specific requirements of the role. For example, in a crisis, an interim CFO with restructuring and liquidity management experience is needed, while M&A-related mandates require transaction expertise.
• Unclear role within the organization: It is often not clearly defined what decision-making authority the interim CFO has and what outcomes are expected.
• Late engagement: Early deployment preserves strategic flexibility for the company. Interim CFOs are often brought in too late, especially in cases of (i) performance or liquidity crises, (ii) risks under existing financing agreements (e.g., covenant breaches, maturities), or (iii) lack of transparency in financial conditions.

Conclusion

An interim CFO quickly creates financial transparency, stability, and decision-making capability in critical situations — provided that the mandate, responsibilities, and expectations are clearly defined.
