Client Overview

The client is a leading telecommunications and data center provider in Central Europe, delivering a broad range of ICT and infrastructure services for wholesale and enterprise customers. With over 600 employees and multiple data centers, the company plays a key role in supporting critical national infrastructure.

Customer Challenge

The client was operating on an aging SAP ECC system that no longer supported its business growth, regulatory compliance, or modernization goals. As the system approached end-of-support, the organization needed a next-generation ERP platform to streamline operations and strengthen security.

Key challenges included:

Outdated system

The legacy ERP environment limited scalability, performance, and vendor support.

High complexity

Extensive customizations and undocumented processes made maintenance difficult and upgrades risky.

Inefficient planning

Financial and project management processes lacked flexibility and real-time visibility.

Strict security demands

As part of the critical national infrastructure, the organization needed to meet stringent security and compliance standards.

Lack of standardization

Non-standard workflows created inefficiencies and inconsistent practices across departments.

What was at stake?

Without modernization, the client risked:

  • Rising maintenance and infrastructure costs.
  • Non-compliance with evolving cybersecurity and governance requirements.
  • Limited business visibility and decision-making capabilities.
  • Reduced process efficiency and employee productivity.
  • Increased operational risk as SAP ECC support was phased out.
