CEN BII standardises eProcurement processes, documents and content, supporting EU-wide interoperability, and covering the full procurement cycle, from notification in the pre-award phase, to payment in the post-award phase.

CEN BII defined a minimum set of core information elements of the documents and business processes involved in electronic public procurement. These are published as a set of technical specifications, called CEN BII profiles, and documented as CEN Workshop Agreements (CWAs).

CEN BII also provided mappings to two syntaxes from OASIS UBL and UN/CEFACT. These are published as Implementation guidelines.

The results from the last phase of the BII initiative (CEN WS/BII 3) include the following CWAs:
