Michiel Sintnicolaas, Managing Partner at Bridgewell, aims in this article to clarify the distinction between an Interim CFO and a Part-time CFO — and when to engage each.
Interim or Part-time CFO?
A Chief Financial Officer (CFO) plays a vital role as the person ultimately responsible for overseeing an organization’s financial operations. In addition to providing insight into corporate strategy, they are instrumental in financial planning, analysis, and guiding the organization’s strategic growth path. Their responsibilities go well beyond managing financial statements or setting up budgets — they also oversee cash flow and other critical financial metrics, offering a comprehensive picture of the organization’s financial health. CFOs also play a key role in steering internal controls and implementing process improvements and transformations.
The value a CFO brings is immense for organizations of all sizes — from startups and scaling companies to small and medium-sized enterprises (SMEs) and large, established corporations. Even businesses that already have a CFO may benefit from considering supplemental CFO services to further strengthen their financial teams. By leveraging the expertise of an external CFO service provider, companies may pursue their financial goals more effectively.
A recent online report from CFO.com reveals a 103% year-over-year increase in demand for Interim CFOs. This surge is primarily attributed to their involvement in leading major transformations, managing workforce reductions and cost savings, executing (re)financing efforts, conducting cost-benefit analyses and investment decisions, and developing annual budgets.
Interim CFO vs. Part-time CFO: What’s the Difference?
When considering the most suitable type of CFO engagement, there are several options beyond the traditional full-time, on-payroll model. In this article, I aim to clarify the difference between an Interim CFO and a Part-time CFO. Both provide financial leadership to the organization, but they differ in aspects such as duration, scope of involvement, and flexibility. The table below provides a clearer comparison:
| Factors | Interim CFO | Part-time CFO |
|---|---|---|
| Duration | Typically brought on for a fixed period, often during transitions such as leadership changes or financial restructuring. May be full-time depending on needs. | Maintains an ongoing, often long-term relationship, offering continuous support and advice on a part-time basis. |
| Scope | Focuses on stabilizing financial crises, managing urgent or specific projects, or handling complex challenges. | Focuses on day-to-day operations, planning, and analysis, offering periodic advice on strategic financial decisions. |
| Engagement | Often requires close and intensive collaboration with internal teams, with high involvement over a short time span. | Typically involves scheduled participation as agreed, with a set number of days or hours dedicated to providing strategic financial and operational guidance. |
| Flexibility | Offers flexibility in terms of engagement duration; once the project concludes, the Interim CFO can exit. | Offers ongoing flexibility and can adapt to the organization’s evolving needs. |
| Cost | Generally higher due to limited, high-intensity involvement and the need for specialized skills. | Lower and recurring cost in an ongoing arrangement. Ideal for SMEs that can’t afford a full-time CFO but still want to benefit from expert guidance. |
Choosing Between an Interim or Part-time CFO
The decision depends on your organization’s specific needs and context. If your goal is to streamline financial operations or gain strategic financial advice to define goals, create short- and long-term plans, and ensure continuous value from these efforts — and your organization doesn’t have the capacity for a full-time CFO — then a Part-time CFO may be the right fit.
If your internal team lacks certain expertise or doesn’t have the bandwidth to tackle urgent projects, engaging an Interim CFO might be the better option. This could involve one-off budget planning, cash flow forecasting, financial valuations, funding needs, capital raising, M&A activity, financial restructuring, business transformation, financial systems implementation, risk assessment, or setting up financial governance structures.
The Future of CFO Services in a Changing Landscape
A dynamic business environment challenges companies and roles to evolve and adapt. As organizations face increasingly complex financial challenges and market uncertainties, the demand for strategic financial leadership will continue to rise. Interim and Part-time CFOs can play a crucial role in helping organizations — especially SMEs and startups — adapt, thrive, and meet their long-term financial goals while optimizing costs and maintaining flexibility.
