Meter readings, invoices, tariff changes, moves: energy suppliers serve households and business customers with many recurring requests. A customer portal connected to SAP and billing takes the load off customer service and the call centre.
AIStarting point
Many utilities introduced their customer portal years ago. Today the systems are reaching their limits: billing runs in SAP, customer data sits in the CRM, and the portal accesses them through interfaces that have grown over time.
At the same time, customers expect to manage meter readings, invoices and contracts themselves at any time, in the browser as well as in the app. Regular maintenance of SAP ERP 6.0 ends at the end of 2027 and can be extended at extra cost until the end of 2030. This also puts the interfaces to the test.

AI2channels on one platform: self-service portal and app, connected to SAP and Dynamics
The customer portal was based on a legacy PHP application that could hardly be extended any more. Self-service for web and app was required.
Java microservices on Azure with Kubernetes replace the legacy application and connect SAP and Microsoft Dynamics. Content comes from Adobe Experience Manager.
Customers handle onboarding, invoices and payment themselves, on the web and in the app.

Regular maintenance of SAP ERP 6.0 ends at the end of 2027 and can be extended at extra cost until the end of 2030. When you move to a new SAP system, the interfaces change. We plan the integration of portal and app in parallel with the SAP migration.
