eInvoicing Directive 2014/55/EU

Last modified:

The CEF eInvoicing building block supports public administrations in complying with the eInvoicing Directive 2014/55/EU, in particular the new European eInvoicing standard (EN16931).

The objective of this Action is to support the uptake of the European eInvoicing Standard (EN16931), mandated by the Directive 2014/55/EU), including both syntaxes (UBL 2.1 and CII) by 8 Icelandic public institutions, allowing them to receive and process EN compliant eInvoices.

Therefore, the 8 Icelandic public authorities will prepare their ERP (Enterprise Resource Planning) systems to the EN by integrating PEPPOL e-Delivery Access Points and SMP registry services (belonging to UNIMAZE) to allow for the cross-border invoice transmission.

Moreover, a central validation service for Icelandic standards (Staðlaráð Íslands) will be set up by UNIMAZE to allow end-users validating a compliant EN invoice. The central validation service will be developed according to the Icelandic context and will facilitate the validation of the CIUS (Core Invoice Usage Specifications) adopted in Iceland.

The Action will enhance the cross-border eInvoicing B2G transactions in Europe and in Iceland, by contributing to the deployment of both the eDelivery and the eInvoicing Building Blocks.
