Peppol ‘BIS’ Specifications – An Overview

Peppol ‘BIS’ Specifications – An Overview

Peppol has developed the Business Interoperability Specifications (BIS) for common eProcurement processes to standardise electronic documents exchanged and validated through an open and secure network, between sending and receiving Access Points for public sector buyers and their suppliers across Europe and beyond.

The eProcurement specifications (Peppol BIS) maintained by OpenPeppol build on the work of the CEN Workshop on Business Interoperability Interfaces for Public Procurement in Europe (CEN BII). Peppol has not developed new standards but has used the CEN BII results to develop implementation guidelines, known as the Peppol ‘BIS’, that can be embedded in eProcurement and eBusiness exchange systems, to support interoperability across borders. The Peppol BIS are formal requirements to ensure pan-European interoperability of procurement documents, such as eInvoices.


In this context, Peppol provides:

  • Peppol Business Interoperability Specifications (BIS) utilising the Universal Business Language (UBL – ISO/IEC 19845)
  • Product catalogues, order/order confirmation/despatch advice, and invoices
  • A range of pre-award Peppol BIS to be released in 2017
