the clock is ticking on legacy systems.

Modernizing your ERP system, particularly migrating from platforms like SAP ECC to S/4HANA, is no longer optional—it's a strategic imperative. With deadlines like SAP's 2027 end-of-support for ECC looming, inaction introduces significant risks.  

But this is far more than just an IT upgrade. ERP migrations carry profound financial, operational, and compliance implications that demand C-suite oversight. Finance leaders are under pressure to:  

  • manage complexity: Navigate intricate changes to financial workflows, data structures (like S/4HANA's Universal Journal), reporting methods, and compliance frameworks.  
  • mitigate risk: Avoid common pitfalls like budget overruns, operational disruptions, compliance gaps, and integration failures with third-party systems.  
  • address talent gaps: Overcome the challenge of upskilling internal teams and managing the significant change required for successful adoption. Research shows many organizations lack the necessary data skills for such transformations.  
  • handle resource intensity: Execute a process that nearly half of organizations find time-consuming and resource-intensive.  

Failing to prepare adequately can derail daily operations and negate the potential benefits of a modern ERP.
