A compliant e-invoice is generated from your ERP, converted to the right country format, validated, and delivered through the right channel. That whole process runs through the output layer. Interform helps you meet e-invoicing and e-reporting mandates across markets, from the systems you already run, with no change to your ERP.
Most European markets now mandate structured invoices. Each country sets its own formats, timelines, and transmission methods, and the same source data has to become a different document depending on where it is going.
Different countries require different formats and different deadlines.
The same invoice must become XRechnung, ZUGFeRD, Factur-X, Peppol BIS or a national format.
Mandates are already live or imminent: Italy, Belgium, Poland, France 2026, Germany 2027 to 2028.
ERP systems cover this unevenly, especially for on-premise, hybrid and IBM i setups.
A single rejected invoice can mean no payment, a regulatory breach, or a stalled supply chain.
E-invoicing is only the start. E-reporting and digital transport documents follow next.
A compliant e-invoice is generated from ERP data, converted to a country format, validated, and delivered. Every one of those steps runs through the output layer, the same layer that already produces your invoices, labels and documents today.
InterformNG2 takes the source data from your ERP, converts it to the format each country requires, validates the structure against the active rules, and delivers it through your existing process. No ERP changes. No new system to introduce.
One output layer that turns any ERP's data into compliant invoices, across every market you trade in.
Connect to Infor, SAP, Microsoft Dynamics, IBM i and other systems from one output layer.
XRechnung, ZUGFeRD, Factur-X, Peppol BIS, UBL, OIOUBL and more, built on the EN 16931 model.
Merge a human-readable PDF with the structured XML that carries the legally binding invoice.
Check each invoice against format rules before it is sent, so fewer documents are rejected.
Peppol network, email, file deposit or print, with distribution available as an add-on.
Format and rule updates ship with InterformNG2 as mandates and profiles evolve.
Auto Nagel, an automotive dealer group in Germany, runs on IBM i. The group is live with XRechnung and ZUGFeRD through InterformNG2, producing compliant e-invoices from the system it already runs, with no change to the ERP.
Read the full case study →E-invoicing is the leading edge of a wider shift to structured, government-regulated documents. E-reporting, digital transport documents and real-time tax reporting are already following on the same networks. This is not only an EU story: other jurisdictions worldwide are introducing their own mandates, on their own timelines. The output layer that handles today's formats is the same one that will handle the next, so you set it up once instead of starting a new project for every market.
