Case St1

Integrated system ensures ability to change


St1 had inherited a number of systems through acquisitions. These systems were incompatible. This made it difficult to gather information and form a comprehensive picture of the situation. The use of separate systems also led to differing operating practices across countries and market areas. The company wanted to ensure that the systems would work together in support of joint operations.

St1 launched the end-to-end overhaul of systems in Finland, Sweden and Norway. Digia was responsible for integrating the systems into a smart solution and providing the ERP system that forms the core of the solution. When all the systems work as a seamless whole, the company has a joint platform enabling the development of business operations.


  • Systems that work together seamlessly provide a stable foundation for business.
  • The solution adapts to meet the challenges of a developing business.
  • Data from different systems forms a comprehensive picture of business operations.
  • Information is easily available from the systems, enabling the development of new services.

Services and solutions:

When we decided to go through with a systems reform, we looked for partners that can be as fast and agile as we are – and who can help us to stay fast and agile in the future, too. Digia convinced us of its ability to carry out wide-scale reforms and to keep control of a project covering several countries.
