One e‑Invoice Platform. Multiple Solutions for Different Organizations.
From a built‑in solution for Business Central to Gateway models for SAP, Pantheon, and other ERP systems. Choose an approach that aligns with your business processes, IT requirements, and growth plans.

All solutions are powered by the same proven Login Systems e‑Invoice platform and provide support for both outgoing and incoming electronic documents. The difference lies in the deployment model, management, and integration with existing ERP systems.
Functionality Available Across All Solutions
Regardless of which solution you choose, all models use the same LSM e‑Invoice platform and provide the core functionality required to work with the UJP e‑Invoice platform. The differences between the solutions relate to deployment, management, and integration with existing ERP systems, rather than the fundamental e‑Invoice capabilities.
