Updated on 22 August 2026. We reviewed the description of tasks, the distinction from an internal CFO and the framework under company law. Nothing in the content has changed since first publication. The legal position has been added: under Art. 716a para. 1 OR, organizing the accounting, financial control and financial planning, as well as the ultimate supervision of management, remain non-transferable duties of the board of directors, and Art. 725 OR obliges the board to monitor solvency. The distinction between a permanent CFO mandate and a temporary interim assignment has been clarified. Still valid without changes: the areas of financial planning and analysis, risk management and compliance, business strategy, leadership of finance teams, process optimization and stakeholder management.

The importance of an external CFO

An external CFO (either permanently on a mandate with a reduced workload or temporarily as an interim CFO) offers not only financial expertise but also a fresh view of the company. The external CFO often brings a wealth of experience from different industries and areas of responsibility.

He or she can provide objective analyses, make recommendations and propose measures that move the company forward. In situations of restructuring, turnaround or transformation, such an interim manager can make a decisive contribution to getting the company back on the right course.

In their role as advisors and strategic partners, external CFOs work closely with management and other departments of the company. They support the development and implementation of corporate strategies and advise on financial questions.

They are also able to optimize processes in the finance area and make accounting more efficient. With a CFO mandate, they support the company in all areas of finance and accounting.

One limit under company law remains: under Art. 716a para. 1 OR, organizing the accounting, financial control and financial planning, as well as the ultimate supervision of management, are non-transferable duties of the board of directors. An external CFO prepares and implements these decisions; the responsibility remains with the board of directors. Art. 725 OR results in a specific task: the board of directors monitors solvency, and an external CFO provides the figures for this.

The most important tasks of an external CFO

External financial planning and analysis

An external chief financial officer not only prepares detailed financial forecasts but also carries out an in-depth analysis of the company’s financial performance.

In doing so, he or she goes beyond the bare figures and examines the underlying causes of certain developments. Based on these analyses, he or she gives strategic recommendations on how the company can improve its financial situation and prepare for future challenges.

Here, he or she contributes expertise in budget planning, CFO functions and finance strategy.

Risk management and compliance

In addition to ensuring that the company complies with all legal regulations and mandates in the finance area, external CFOs identify financial risks that could threaten the company.

They develop processes and strategies to minimize these risks. This can include, for example, implementing security measures in IT and finance to be prepared for potential threats.

They also keep the company up to date on changes in legal regulations or in investor relations.

Business strategy and growth initiatives

With their in-depth industry knowledge and their know-how in business management, external CFOs are ideally placed to help companies develop growth strategies and business initiatives.

They often take a fresh look at situations and can therefore offer new perspectives and approaches. This includes analyzing market opportunities, developing business models and implementing growth plans.

Managing finance teams and departments

An external CFO not only leads finance teams but also ensures their further development. This can happen through training, workshops or the introduction of new processes.

The focus is always on increasing efficiency and preparing the teams optimally for future requirements.

Optimizing business processes

Inefficient processes can cost companies a lot of money. An external CFO identifies such weak points and proposes improvements. These can range from simple adjustments to complete restructurings.

With their expertise, external CFOs can often make processes leaner and so help increase productivity.

Managing relationships with stakeholders

Communicating and maintaining relationships with investors, banks and other stakeholders is essential for a company’s success. External CFOs often have a large network and the necessary experience to maintain these relationships professionally and to the company’s advantage.

They represent the company on financial matters and build trust among stakeholders.

Working successfully with an external CFO

Choosing the right external CFO

Choosing the right interim CFO or interim manager CFO is crucial to a company’s success. What matters here is not only sound professional experience and expertise in finance, but also knowledge of the specific areas on which he or she is to advise.

A solid core competence in topics such as accounting, financial planning or risk management can contribute significantly to success.

Beyond that, however, the external CFO should also be a cultural fit for the company. This means that his or her way of working, values and strategic approaches should be in line with those of the company. Mandates and specific roles of the CFO should be clearly defined in advance to avoid misunderstandings.

All about the CFO mandate

Communication and collaboration

One of the main tasks of an external CFO is communicating effectively with management, the CEO and other members of the management team.

An open dialogue, regular updates and a transparent exchange of information are the foundation of successful collaboration. Regular meetings, both in person and virtual, should be scheduled to discuss current developments, problems and possible solutions.

It is also important that the CFO has access to all relevant information and data in order to make well-founded decisions and recommendations.

Integration into the existing team

Even if an interim CFO is not permanently on site at the company, he or she should still be regarded as a full member of the team. This makes integration easier and ensures that he or she is accepted and respected by other team members.

It is important that the CFO works with employees not only at management level but also at operational level. This promotes understanding and respect on both sides.

Frequently asked questions

How does an external CFO differ from an internal CFO?

An external CFO works on a mandate rather than as an employee: either permanently with a reduced workload or temporarily as an interim CFO; the two models are not the same. An internal CFO, by contrast, is permanently employed by the company and holds the position full-time over the long term.

What advantages does an external CFO offer compared with an internal CFO?

An external CFO offers flexibility, because he or she can be brought in as needed and on a project basis, which allows companies to save costs. With experience from various industries and companies, an external CFO often brings new and innovative approaches that might not occur to an internal CFO. The objective outside view makes it possible to carry out unbiased analyses and make recommendations that are free from internal politics or prejudices. In addition, an external CFO can bring valuable industry contacts and networks that can open up new opportunities for a company.

How do I find the right external CFO for my company?

To find the right external CFO for your company, you should first define clearly which specific tasks and requirements need to be met. When choosing, it is important to consider both the candidate’s professional expertise and his or her cultural fit with your company. References and testimonials from previous mandates can provide valuable insights and help assess the CFO’s suitability. Finally, a personal meeting or interview can be decisive in making sure that the CFO works well with management and the team.

What qualifications should an external CFO have?

An external CFO should have a sound university education in finance or business administration. Several years of professional experience in senior finance positions and in-depth know-how in areas such as financial planning, risk management and compliance are important. The ability to provide strategic business leadership and strong expertise in optimizing business processes are essential. An external CFO should also have excellent communication skills in order to interact effectively with management, employees and external stakeholders. Finally, adaptability and the ability to settle quickly into different corporate cultures and structures are a great advantage.

Can an external CFO also take on other roles?

Yes, an external CFO can certainly take on other roles as well, depending on his or her qualifications and the specific needs of the company. In addition to traditional finance tasks, an external CFO can, for example, also take on tasks in strategic management, corporate development or even in executive management. In situations of restructuring or turnaround, he or she can also act as an interim manager or advisor. Thanks to extensive professional experience and expertise, an external CFO is often able to work beyond the pure finance area and make valuable contributions in various parts of the company.
