One customer came to us with some very specific goals: 1) reduce the Total Cost of Ownership (TCO) for ERP solutions, 2) improve financial efficiency by cutting the monthly close process time by 50% and 3) establish a scalable platform for future business growth. To help our customer achieve these ambitious objectives, Answerthink created a plan to migrate their highly customized legacy ERP system to SAP S/4HANA Public Cloud.

Key Challenges

Before implementing SAP S/4HANA Public Cloud, the company faced several operational challenges:

  • A heavily tailored on-premise ERP system that was costly to maintain.
  • The existing ERP acted as an “Interface Hub” for multiple ancillary systems, creating integration complexities.
  • A need to implement Central Invoice Management (CIM), a process that was new to the organization.
  • Specific formatting requirements for quarterly and annual financial reports.

Implementation Highlights

The transition to SAP S/4HANA Public Cloud was executed over a 26-week period, with hyper-care support following the go-live phase. Key implementation steps included:

  • Migrating core finance and procurement operations to the new system.
  • Deploying Central Invoice Management to streamline financial workflows.
  • Integrating SAP Analytics Cloud (SAC) for advanced financial reporting.
  • Standardizing business processes across departments.
  • Leveraging SAC for enhanced financial reporting capabilities.

Why SAP S/4HANA Public Cloud?

The organization selected SAP S/4HANA Public Cloud for several compelling reasons:

  • Cost Efficiency: The cloud-based model reduced operational costs while eliminating expensive legacy system maintenance.
  • Scalability & Visibility: SAP’s robust capabilities provided a foundation for continuous growth and operational transparency.
  • Continuous Innovation: Biannual upgrades ensured the organization remained at the cutting edge of technology.

Business Benefits Realized

Since the successful implementation of SAP S/4HANA Public Cloud, the company has experienced significant improvements, including:

  • Faster time-to-value with cloud deployment.
  • Adoption of industry best practices for optimized workflows.
  • Enhanced process efficiencies across financial and procurement functions.
  • A future-proof ERP environment with regular system enhancements and updates.

Conclusion

By migrating to SAP S/4HANA Public Cloud, our customer successfully modernized its operations, reduced costs, and positioned itself for sustainable growth. The transformation not only streamlined financial management but also established a foundation for continuous innovation, ensuring the organization remains agile in a dynamic industry landscape.
