LS-Peppol Specifications

Full-featured and powerful, yet small and simple, ebMS3/AS4 server custom-built for Peppol.

LS-Peppol is a small, fast, efficient, and feature-rich ebMS3/AS4 server designed for business software applications needing an easy way to directly send and receive documents on the Peppol network.


LS-Peppol makes it easy to self-host your own Peppol server.

It has been custom-built to be easy to install, manage and run, so that you can be your own certified Peppol Service Provider, and effortlessly exchange documents on the Peppol network.

Packed inside a tiny (4 MB) executable, LS-Peppol provides a powerful, all-in-one Peppol server which seamlessly integrates both an ebMS3/AS4 Access Point (AP) and a Service Metadata Publisher (SMP).

Applications can easily send/receive Peppol documents and manage the LS-Peppol server using the simple-to-use companion LS-Peppol client (LS-B2B).

LS-Peppol has many advanced features including strong security, server management, certificate provisioning, recipient discovery, multi-level authorisation, statistics, and conformance to all the Peppol and related international standards. 


LS-Peppol is a simple, all-inclusive, tiny (4 MB) and highly efficient server.

All aspects of being on the Peppol network are supported including:

  • Messaging - AS4 (push, pull), lookups (SMP, SML), provisioning (SMP, SML, Peppol Directory), etc.

  • Operations - logging, notifications, security, certificate renewal, etc.

  • Management - statistics, provisioning, auditing, etc.

Notably, LS-Peppol seamlessly integrates all required servers and clients into a single executable:

  • 6 inbuilt servers – gateway, SMP, lookup, certificate, provisioning, and console.

  • 9 inbuilt clients – AS4, SML, SMP, register, credentials, licence, audit, email, and database.
