In 2021, Liège took a significant step forward by replacing its legacy mainframe system with a more agile and powerful solution. This ambitious project, led by Inetum’s expertise, improved internal process efficiency and strengthened financial transparency.
Facing the limitations of a costly and obsolete system, the City of Liège turned to Microsoft and Inetum to lead its digital transformation. Inetum played a key role in designing and deploying a Microsoft Dynamics 365 F&O solution tailored to public authorities.

By adopting an agile methodology, the project was completed in just ten months.
Today, a dedicated team within the City of Liège manages the system, while Inetum continues to provide maintenance and support for further optimization.
