E-invoicing

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

How Interform fits in

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.

• Convert invoice data into structured formats
• Validate invoices before sending
• Route invoices through the correct channels
• Handle country and customer-specific requirements
• Adapt to changes without modifying your ERP

What Interform delivers

• Generate formats such as PEPPOL, XRechnung, OIOUBL, ZUGFeRD, and Factur-X
• Transform ERP data into XML-based or hybrid invoice formats
• Validate invoices against format specifications before delivery
• Combine structured data with PDF output where required
• Route invoices automatically based on defined rules
• Integrate with ERP systems, eDelivery networks, and external platforms

Benefits

• Support compliance across markets - meet invoicing requirements across countries, customers, and networks.
• Reduce rejection risk - validate invoices before sending to reduce errors, avoid rejections, and prevent delays.
• Keep ERP complexity under control - handle formats and delivery logic outside the ERP system.
• Work with one invoice process - use a single source of invoice data across all formats.
• Stay ready for change - adapt to new standards and requirements without redesigning your setup.

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.
