The EU’s Directive EN 16931 is pivotal in standardising electronic invoicing (E-Invoicing) across member states, fostering efficiency and harmonisation in B2B, B2G, and G2G transactions. Compliance with this directive empowers businesses to leverage reduced costs, increased efficiency, improved accuracy, faster processing, and greater transparency.
What is EN 16931?
EN 16931 is the cornerstone of the EU’s directive to standardise electronic invoicing for public procurement across member states. As a critical element of Directive 2014/55/EU, it establishes a unified semantic data model for electronic invoices, ensuring interoperability and mutual understanding of invoice content regardless of the systems used. This standard facilitates using different syntaxes like UBL and UN/CEFACT CII, aligning with the semantic model to ensure broad compatibility and accessibility.
The Vision
The directive’s overarching goal is to enhance the Digital Single Market, making digital and cross-border trade within the EU seamless and efficient. By introducing a unified E-Invoicing standard, the EU aims to dismantle trade barriers, particularly for SMEs, promoting a more competitive and integrated market. This initiative is part of a broader commitment to digital transformation designed to streamline public procurement processes, reduce transaction costs, and accelerate payment cycles, fostering a more dynamic EU economy.
Key Benefits for Your Business
EU Directive EN 16931, formally known as the European Standard on Electronic Invoicing (ESI), represents a significant legislation aimed at harmonising e-Invoicing across the European Union. Introduced to ensure interoperability and compatibility among different e-invoicing systems, the directive focuses on reducing administrative burdens and costs for businesses while enhancing the security and reliability of e-invoicing. It promotes the widespread use of e-invoicing in B2B, B2G, and G2G transactions, contributing to a more efficient and digital EU economy.
Simplified Processes: Navigate cross-border transactions easily, thanks to a unified invoicing standard.
Cost Reduction: Lower administrative costs by minimising the need for multiple invoicing formats.
Ensuring Compliance
To ensure compliance with EN 16931, businesses must follow a structured approach encompassing three compliance levels:
- Invoice Document: Every electronic invoice created and sent must adhere to the rules defined for the core invoice or the relevant CIUS (Core Invoice Usage Specification) it is based on. This includes mandatory including all necessary information, structuring information as specified, accurately calculating amounts, and using allowed values such as codes.
- Implementation: Both senders and receivers of electronic invoices must be compliant. Receivers are required to accept and process all invoices that meet the EN 16931 core data model or any applicable CIUS, ensuring broad interoperability. Senders must be capable of creating invoices that conform to these standards.
- Specification: If an invoice and its implementation are based on a CIUS, CIUS must not deviate from the core rules, ensuring that anyone receiving the full core can also process any compliant CIUS.
Comparing E-Invoicing Standards: EN 16931 and Its Global Interoperability
| Feature | Description | EN 16931 (EU) | Global Standards |
