Peppol - What is it?

Peppol is the common delivery network chosen to enable the automated issuing, transmission and receipt of electronic invoices, managed and maintained by nonprofit organization OpenPeppol.

Finologee is a member of OpenPeppol which is the official Peppol Authority for Luxembourg. Being a member gives Finologee access to the European Peppol community, the official Peppol documentation and technical specifications related to the Peppol ecosystem.  Finologee is also a certified Peppol Service Provider for eDelivery and Post-Award services and has passed the official OpenPeppol certification procedures.

What can I do with the LYNKS Peppol module?

Finologee’s Peppol Access Point can be used for exchanging documents with public authorities and institutions, as well as for business-to-business and business-to-consumer workflows. The aim is to enable companies to use the Peppol network to transmit messages such as invoices and orders more efficiently and securely.

The module’s advantages at a glance:

Sending & receiving standards-based electronic documents

(B2G & B2B)

Encrypted communication & non-repudiation
Used in 40 countries

(EU, North America, Asia, Africa, Australia)

e-Advance Shipping notes

Your gateway for compliant e-invoices to public sector clients and beyond


Until now, many countries have been working with their own standards for e-invoicing. These national standards will gradually be phased out and replaced by Peppol, the EU standard for exchanging electronic documents.

The aim of Finologee’s Peppol Access Point is to allow companies to connect to Peppol network and thus, to exchange electronic documents such as invoices and credit notes based on the Peppol technical specifications.

Exclusive feature: Automate e-invoice reconciliation with incoming payments

The Peppol module deployment on Finologee’s LYNKS platform enables a tight integration with the platform’s core payment features: outgoing (and incoming) e-invoices sent over the Peppol network can be mapped with incoming (and outgoing) payments. Thus monitoring and reconciliation of the payment processes can be fully automated, providing an up-to-date oversight on payments and statuses, also facilitating actions and escalation procedures.

As all other LYNKS Peppol components, the Reconciliation component is available both through a secure web interface with advanced users and rights management and over the LYNKS API endpoint.

How does it work?

The LYNKS invoice management interface is designed to enable businesses to streamline the following tasks:

  • Submit proprietary files that contain invoice or credit note information and convert them to the official Peppol BIS 3.0 format
  • Deliver electronic documents (invoices, credit notes) to any participant in the Peppol network world-wide
  • Receive electronic documents from any Peppol participant
  • Archive documents for non-repudiation.

As a certified Peppol Access Point, Finologee takes care of the fast and secure transfer of your invoices – in a structured format (XML) – to the recipient’s Access Point. Authentication and integrity of messages is established by means of digital signatures applied to the message. This allows receivers of documents to verify the identity of the sender and the consistency and integrity of the document. At the same time, it allows the sender to receive signed responses by the receiver to prove that the latter has irrefutably accepted a given document.

Simple & secure integration with your systems

Users access the module either through secure web browser connections or by linking existing IT and operational systems with the LYNKS APIs available on Finologee’s secure API portal.

LYNKS endpoints – how to connect to the module

Connectors are the interfaces that participants can use to send and receive documents through the Peppol network. They offer conversion and validation capabilities to make sure that the documents that are being sent are compliant with the Peppol specifications and that the received documents can properly be ingested by the participants’ backend systems.


Finologee’s simple REST API is the perfect starting point for getting familiar with the Peppol network functionalities and comply with the legal requirements in a quick and straight-forward way. It includes only the mandatory parameters of the Peppol documents.

Complete REST API

If the simple REST API is not sufficient for a given use case, it can easily be expanded to use the complete API that gives access to all of the Peppol document features.

File upload via HTTPS and SFTP

Finologee also supports file uploads through an HTTPS or SFTP interface in various flat file formats (CSV, Excel, Text etc.)

Success Story - LALUX Assurances sending invoices via LYNKS

The well-known Luxembourg insurance company LALUX is using the Finologee Access Point to send electronic invoices to the Luxembourg Government, public institutions and municipalities. LALUX connects to the Peppol network over the access point provided by Finologee’s Lynks Peppol module.

Prior to automating and streamlining this setup and processes, LALUX had to manually convert its standard invoices into the Peppol format using the template provided by the Luxembourg Government, which required time and effort. Now, sending invoices is simplified as LALUX transmits its invoices through the Peppol network via Lynks.

Finologee handles

  • conversion of invoice files into the right format
  • locates the access point connected to the end user (i.e. the Luxembourg Government access point) to send the invoice;

and then the receiving access point forwards the invoice to the end user, which in this case is the Luxembourg Government.

The Peppol network provides the Peppol Business Interoperability Specification (BIS) using the Universal Business Language (UBL) format, which is a compliant implementation of the European eInvoicing standard.

At present, only few private sector businesses are already connected to the Peppol network, so LALUX’s main use case will be the transmission of e-Invoices to the Luxembourg government, institutions and municipalites (B2G). Once more businesses will have implemented their connections to the Peppol network, they will be able to route and exchange invoices and invoicing data over this network between each other.
