1. Expert Group on e-Invoicing - Mission
Defined in Commission Decision of 31 October 2007:
§ Identify shortcomings in current regulatory framework
§ Define e-Invoicing business requirements
§ Address relevant e-invoicing data elements (and linkages)
§ Propose responsibilities for standardisation bodies and time
schedule
§ Propose a European e-Invoicing Framework - a common
conceptual structure

2. Definition and components
of the European e-Invoicing Framework

3. Vision and target picture
• E-invoicing becomes predominant within 5-8 years, in some
countries earlier.
• Harmonised and clear legal environment will exist across the EU.
• Trading parties have wide choice of convenient solutions and
services- bilateral, 3-corner and 4-corner models in use.
• Standards adopted based on single data model- UN/CEFACT CII.
• Investments made in ERP and supply chain systems and in low
cost and user friendly solutions. For SME’s no investment in IT
solutions or IT skills needed.
• Expected dematerialisation of other processes.

4. Expert Group Recommendations
The EG recommends the creation of an e-invoicing eco-
system that provides maximum interoperability and reach.
Detailed recommendations:
• the use of consistent terminology to describe and clarify the roles and
responsibilities;
• content standards that support the basic cross-industry e-invoicing business
requirements;
• the use of common, non-proprietary European and international information
technology standards;
• minimum business and technical requirements for connectivity and messaging;
• the development of an interoperable electronic addressing and routing process;
• the development and deployment of a variety of accepted business and
implementation models;
• the use of good practice guidelines as self assessment tools on a voluntary basis;
• establishing sound and enforceable agreements;
• to provide interoperability within and between networks and network-based
solutions.

development of a healthy and vibrant

6. First analysis - consultation feedback
Inter-operability
• Vast majority of respondents recognises inter-operability as one of the key requirements
which are critical for the success of EEIF
• Majority of replies agrees with the ‘eco-system’ proposed by EG, at least in principle
• The following key areas of improvement and open issues were identified by respondents:
• Current proposal rather vague and 'theoretical'. Concrete rules for inter-operability
need to be developed. Clearer assignment of tasks and responsibilities required.
• Strong link between invoices and payments. Therefore, requirements in relation to
payment messaging standard ISO 20022 should be included.
• Addressing and routing issues not sufficiently covered in proposal. Clear rules in
this area are a crucial prerequisite for inter-operability.
• Definition of an eco-system should also include description of different business
models for service providers
• As regards implementation of an eco-system, diverging opinions whether such a
framework should evolve through market forces or required intervention.
