E-invoicing fully integrated in a solution supporting mandates across Europe: Onventis new Premium partner of Peppol.now

The Hague, [date] – Onventis is a Premium partner of Peppol.now. As a European Source-to-Pay software provider, Onventis supports mid-market and large enterprises in digitalising and automating their full procurement and financial processes. Through the Onventis E-invoicing Service, customers connect to the Peppol network to receive and process e-invoices directly within the platform. Onventis has been active since 2000 and operates from seven European offices.

Many organisations embarking on e-invoicing today find that connecting to Peppol is only part of the challenge. The real complexity lies in integrating e-invoicing with existing procurement and financial processes: how do procurement teams maintain control over suppliers and budgets, while finance simultaneously manages invoice flows and stays compliant? Onventis is built to bring those two worlds together in a single platform.

A European Source-to-Pay platform built on data sovereignty

Onventis develops and maintains a modular SaaS suite covering the full Source-to-Pay journey: from supplier management, sourcing and tendering to contract management, operational procurement, invoice processing and spend analytics. All modules are integrated within a single environment, enabling organisations to digitalise their procurement processes end-to-end without relying on separate systems or manual connections. Onventis operates from offices in Stuttgart, Düsseldorf, Rijswijk, Stockholm, Paris, Vienna and Warsaw.

A deliberate architectural choice in the Onventis platform is its commitment to European data sovereignty. In a market where many platforms host their infrastructure outside the EU, Onventis offers a protected European data environment. Procurement and finance teams retain full control over data, costs and process flows, in line with internal policies and applicable regulatory requirements. For organisations in regulated sectors or with strict data governance requirements, this is not a secondary concern but a concrete selection criterion.

Today, around 1.2 million users from more than 1,000 companies process an annual transaction volume of EUR 40 billion through the Onventis network, with access to a supplier base of 4.5 million parties. Onventis employs approximately 250 people and serves clients in sectors including manufacturing, automotive, chemicals, food and beverage, wholesale and professional services.

The Onventis E-invoicing Service: Peppol embedded in the procurement process

E-invoicing at Onventis is not a standalone product. Through the Onventis E-invoicing Service, customers receive and process e-invoices via the Peppol network directly within the platform’s Invoice Processing module. This ensures the full procure-to-pay cycle is handled digitally and compliantly, without the need for separate tools or infrastructure.

The platform supports widely used ERP integrations including SAP, Oracle, Microsoft Dynamics, Infor, AFAS and Exact. In addition to Peppol connectivity, Onventis supports EDI standards such as EDIFACT, openTRANS and cXML, enabling organisations with diverse trading partners and country-specific requirements to operate from a single environment.

For organisations seeking to embed Peppol connectivity within a broader finance and procurement environment, this represents a meaningful distinction from standalone e-invoicing solutions. The invoice flow is not a separate data stream, but an integral part of the procurement process from order to payment.

E-invoicing and compliance: from obligation to strategic choice

E-invoicing is rapidly evolving from an optimisation to a mandatory component of financial processes. Across Europe, more and more countries are introducing B2B e-invoicing mandates: Belgium launched its obligation in 2026, France follows later this year, and with ViDA a European framework for VAT reporting is taking shape that will tighten requirements further. For organisations operating across multiple countries, this means compliance can no longer be managed country by country, but must become part of a coherent European strategy.

The Onventis platform supports multiple formats and country-specific requirements within a single environment. This makes it possible to comply with both Peppol BIS 3.0 and other national standards without implementing a separate solution for each country. For international organisations seeking to maintain compliance and operational continuity, that is a concrete advantage.

Onventis Onix: AI as an integral part of Source-to-Pay

Onventis Onix is the agent-based AI platform that provides intelligent support across the full Source-to-Pay journey. From automated spend analysis and smart contract alerts to AI-driven invoice matching and process optimisation: Onventis Onix makes AI use transparent and manageable.

For procurement teams, this means routine tasks can be further automated while strategic decisions are supported by real-time insight into spend, contracts and supplier performance. At Onventis, AI is not an add-on but an integral part of how the platform works.
