The control center for your e-invoicing in Europe

E4E - Engine for E-Invoicing

The control center for your e-invoicing in Europe

With the Engine for E-Invoicing (E4E), you can manage your electronic invoicing processes centrally, efficiently and legally compliant - across national borders. The cloud-based SaaS/PaaS solution automatically converts your outgoing documents - such as invoices or credit notes - into the legally required e-invoice format.

E4E reduces manual effort, ensures compliance with national requirements and creates transparency in complex regulatory landscapes - whether in Germany, Italy, Poland or other European markets. 

Central control of all e-invoicing processes

From creation to delivery - E4E bundles the entire invoice flow in a central system. This creates transparency, reduces manual intervention and ensures legally compliant processes. 

Legal compliance for Europe - always up to date

Whether ZUGFeRD, XInvoice, Factur-X or KSeFE4E automatically fulfills country-specific requirements - centrally updated and always compliant. 

Quick introduction, individual configuration

The solution is ready for operation in a short time and can be flexibly adapted to processes and organizational structures - multi-client capable, scalable and efficient in operation. 

Compatible with leading ERP systems

E4E supports your ERP processes - seamlessly integrated into your existing ERP landscape. This allows you to create added value without changing your systems.

One system for the whole of Europe

E4E replaces country-specific individual solutions with a standardized platform. New countries, formats or regulatory requirements can be easily added. 

Technically ready for the future

Web service-based, modularly expandable and powerful - E4E is designed for increasing volumes, new standards and long-term process reliability. 

Centralized control. Full compliance.

1. document recording - flexible & open format

E4E accepts individual document formats such as XML, JSON or CSV - exactly as they are created in your system. Data is transferred flexibly via REST API, file upload or via established exchange methods such as FTP/SFTP. 

This allows a wide variety of ERP systems to be connected securely and efficiently. 

2. validation, mapping & transformation - intelligently controlled

The integrated mapping engine ensures rule-based mapping of your content - including validation of legal requirements and optional customer fields. 

Individual requirements are taken into account, as are country-specific regulations. 

3. target format generation & mandate control - precise & compliant

E4E automatically generates the required e-invoice format - for example XInvoiceZUGFeRD, FatturaPA or KSeF. You define which clients, networks or recipients receive the output - flexibly controllable and multi-client capable. 

4. dispatch & feedback - automated & traceable

E4E transmits completed invoices directly to recipients, authorities or networks such as PEPPOL - including feedback to the ERP system. All steps are logged and can be tracked at any time in the monitoring system. 

5. archiving & compliance - audit-proof documentation

All versions, error logs and shipment histories are stored centrally. This allows you to meet internal requirements as well as statutory retention obligations - transparently, securely and retrievable at any time.
