Business strategy operations

When your finance team experiences disruption, your ability to deliver timely, accurate and strategic financial insights is at risk. In the middle market, even a short gap in leadership or capacity can derail decision making, erode investor confidence, create compliance risk and slow down growth initiatives.

RSM’s chief financial officer (CFO) advisory team provides interim accounting and finance support designed to keep your operations running without interruption. We offer seasoned interim CFOs and controllers, highly skilled accountants and complete finance teams. Under your oversight, our professionals integrate with your operations, help stabilize performance and focus on your long-term strategic goals.

A complete range of interim finance solutions

Our interim services are designed to scale with your needs and can address situations ranging from short-term capacity gaps to major leadership transitions or operational overhauls.

RSM’s interim CFO and controller services offer experienced executives who can step into a leadership role. These professionals are accustomed to managing through IPO readiness, complex carve-outs, post-acquisition integrations, restructurings and performance turnarounds. They focus on maintaining operational stability while advancing the company’s broader agenda.

Our staff augmentation services provide highly skilled finance and accounting professionals to meet short-term workload demands. Whether it’s preparing for an audit, supporting month-end close, handling reconciliations or managing integration workstreams after an acquisition, our professionals strive to deliver results without disrupting established processes or standards.

RSM’s interim finance and accounting solution provides overall strategy, hands-on resources and operational experience. This allows RSM to take on all or part of your finance function, implementing efficient, technology-enabled processes and delivering high-quality results.

Why interim CFO support is critical

Middle market organizations are operating in an environment of unprecedented complexity. Hiring a permanent CFO or senior controller often takes months, and the talent shortage extends well beyond leadership roles. At the same time, finance functions are being asked to manage significant transformation initiatives. Private equity transactions, carve-outs and integrations are occurring at a rapid pace, adding to the strain.

In addition, the regulatory environment demands experience in areas like environmental, social and governance reporting, revenue recognition and evolving tax requirements. Without interim support, these realities can lead to missed deadlines, regulatory risk, stalled initiatives and diminished stakeholder confidence.
