Stay compliant with changing 
E-invoicing requirements 

Electronic invoicing is becoming a legal requirement in many countries.  Interform helps you generate, validate, and deliver structured electronic invoices in the required format and through the right channel, without adding complexity to your ERP. 

E-invoicing is no longer just about digital efficiency

It is increasingly driven by legal and regulatory requirements. Businesses must be able to issue and receive invoices in structured formats that meet country-specific standards and validation rules. These requirements differ across markets and continue to evolve.

For organisations operating internationally, this creates complexity. 

Invoice formats, delivery methods, and validation rules vary depending on the country, customer, or network. Managing these differences directly in the ERP increases complexity and requires ongoing maintenance. 

Interform allows you to handle these requirements in one place, while keeping your ERP focused on core business processes. 

Interform helps ensure that invoice data is structured, validated, and delivered in line with these requirements. 

Interform sits between your ERP and your delivery channels, handling format, validation, and routing. 

Invoice data is generated in your ERP. Interform then transforms, validates, and delivers the invoice based on the required format and routing rules. 

This gives you a consistent invoicing process, while supporting different compliance requirements.

One setup, multiple compliance requirements 

Organisations operating across several markets often face different invoicing requirements. One customer may require 
PEPPOL invoices. Another may require country-specific formats such as XRechnung or ZUGFeRD. In some cases, PDF invoices are still needed alongside structured data. 

With Interform, invoice data is created once in the ERP. 
Interform converts the data into the required format, 
validates it against the relevant specifications, and sends it through the correct channel. 

This provides one consistent invoicing process, while supporting different compliance requirements across countries and customers. 

E-invoicing requirements are changing

Managing them does not have to be complex. Interform supports the technical requirements of e-invoicing, while your organisation remains in control of regulatory interpretation. Interform helps you meet technical invoicing requirements while keeping your ERP setup simple and controlled.
