Deutsche Bahn – Transportation/Railway Industry

The project focused on designing and implementing a next-generation invoicing and billing platform for B2B German railway clients. These clients rent and use railway infrastructure, and the system is responsible for accurately tracking usage and generating invoices for amounts exceeding €500 million per month. The solution was built with a scalable and extensible architecture, ensuring long-term adaptability with minimal overhead. It streamlines the end-to-end invoice lifecycle – from creation and correction to cancellation, renewal, and secure storage.
