PD CEN/TR 169314:2017CEN/TR 16931-4:2017 (E) 4 Introduction The European Commission states that “The mass adoption of e-invoicing within the EU would lead to significant economic benefits and it is estimated that moving from

24、paper to e-invoices will generate savings of around EUR 240 billion over a six-year period” 1. Based on this recognition “The Commission wants to see e-invoicing become the predominant method of invoicing by 2020 in Europe”. As a means to achieve this goal, Directive 2014/55/EU 2 on electronic invoi

25、cing in public procurement aims at facilitating the use of electronic invoices by economic operators when supplying goods, works and services to public administrations (B2G), as well as the support for trading between economic operators themselves (B2B). In particular, it sets out the legal framewor

26、k for the establishment and adoption of a European Standard (EN) for the semantic data model of the core elements of an electronic invoice (EN 16931-1). In line with Directive 2014/55/EU 2, and after publication of the reference to EN 16931-1 in the Official Journal of the European Union, all contra

27、cting public authorities and contracting entities in the EU will be obliged to receive and process an e-invoice as long as: it is in conformance with the semantic content as described in EN 16931-1; it is represented in any of the syntaxes identified in CEN/TS 16931-2, in accordance with the request

28、 referred to in Paragraph 1 of Article 3 of Directive 2014/55/EU; it is in conformance with the appropriate mapping defined in the applicable subpart of CEN/TS 16931-3 (all parts). The Standardization Request issued by the European Commission in connection with Directive 2014/55/EU requested that CE

29、N should also develop Guidelines on interoperability of electronic invoices at the transmission level, taking into account the need of ensuring the authenticity of the origin and the integrity of the electronic invoices content, to be given in a Technical Report (TR) The Guidelines cover interoperab

30、ility at the transmission level for invoices based on the core invoice model and its syntax representations to and from the involved trading and supporting parties. They could also be applied more widely to cover the transmission of electronic invoices rendered in other standards and formats i.e. th

31、ey are invoice content and format neutral. The Guidelines for interoperability at the transmission level (the Guidelines) are intended to guide all stakeholders who make use of e-Invoicing within the European Union (EU) and the European Economic Area (EEA), and Switzerland. They are addressed to tra

32、ding parties, service and software providers in relation to the transmission methods or network solutions they use or support, in order to encourage the adoption and further development of good practices, recommendations and standards for the transmission level. This is intended to promote efficient

33、, cost effective and widely available e-Invoicing practices and services. It is expected that some groups of stakeholders, such as small and medium-sized businesses (SMEs) and smaller contracting authorities, may find these Guidelines inherently technically challenging and inaccessible at a practica

34、l level. This is recognized, and consequently it is important that at a context-specific level e.g. at Member State or Sector level, policy-makers, larger contracting authorities, SME representative and municipal associations, supportive government agencies, professional advisers, and service and so

35、lution providers take responsibility to guide such organizations in relation to these Guidelines. It is by the nature of the Guidelines that the provision of further specific guidance for SMEs and smaller contracting authorities could not be done at a European level, but rather at national and secto

36、r-specific level, It is recommended that the Guidelines set out herein are adopted by market participants, in such a way that separate and competing approaches, solutions and networks find common ground at the PD CEN/TR 169314:2017CEN/TR 16931-4:2017 (E) 5 transmission level, and on the basis of whi

37、ch trading parties are able to reach the maximum number of their counterparties in a convenient manner. The Guidelines leave as many aspects as possible as a matter of choice or in the competitive domain by only focusing on those features of transmission that are essential to establishing interopera

38、bility. It is envisaged that a large number of network and network-based solution instances will subscribe to and adopt the Guidelines. There is a clear separation between the Guidelines and the design and implementation of individual network and transmission solutions, which range from use of the o

39、pen Internet through virtual private Networks and managed services. The Guidelines are neutral as to the individual interoperability models that the market develops and uses to accelerate the mass adoption of e-Invoicing. The following EU stakeholders have been consulted in addition to the Members o

40、f CEN/TC 434 and their supporting National Standards Organizations (NSOs): European Multi Stakeholder Forum on e-Invoicing; European Commission units responsible for EU Large Scale Pilots, in particular e-SENS DIGIT, DG CONNECT, DG GROW, and for the Connecting Europe Facility (CEF) in particular the

41、 Digital Service Infrastructure for e- Delivery; OpenPEPPOL Association; European E-invoicing Service Providers Association (EESPA). PD CEN/TR 169314:2017CEN/TR 16931-4:2017 (E) 6 1 Scope This Technical Report recommends a set of Guidelines to ensure interoperability at the transmission level to be

42、used in conjunction with the European Norm (EN) for the semantic data model of the core elements of an electronic invoice and its other associated deliverables. The Guidelines are by nature non-prescriptive and non-binding. These Guidelines take into account the following aspects: 1) recommending be

43、st practices for use at the transmission level; 2) supporting interoperability between all the parties and systems that need to interact and within the various operating models in common use; 3) ensuring a level playing field for the various operating models and bi-lateral implementations and for th

44、e use of existing and future infrastructures, which support e-Invoicing; 4) promoting a common terminology and non-proprietary standards for transmission and related areas; 5) ensuring the authenticity of origin and integrity of electronic invoice content; 6) providing guidance on data protection, o

45、n the enablement of format conversion, and on e-invoice legibility, including the use of a readable visual presentations, as required; 7) providing guidance for identification, addressing and routing; 8) identifying requirements for robust legal frameworks and governance arrangements; 9) recognizing

46、 the roles of trading parties, solution and service providers and related infrastructure providers. The Objectives of the Guidelines are: 10) to support the implementation of the EU Directive 2014/55/EU on e-Invoicing and the core invoice model; 11) to propose best practices and recommendations for

47、standards to enable electronic exchange of e-Invoices and related data between participants by providing a basis for interoperability at the transmission level, based on common requirements and scenarios; 12) to facilitate Straight Through Processing (STP) by the key actors in the supply chain (Buye

48、rs, Sellers, Tax Authorities, Agents, Banks, Service and Solution Providers, etc.); 13) to provide a set of non-prescriptive and non-binding Guidelines and recommendations that are applicable to all common operating models for e-invoice exchange and transmission whilst also providing recommendations

49、 specific to each of the common operating models. To accomplish these objectives, the Guidelines are based on the following Requirements and Guiding Principles: 14) the need to cover the transmission of e-invoices and related documents from the system of the sending trading party to the system of the receiving trading party, including transmission issues for any intermediary platforms; PD CEN/TR 169314:2017CEN/TR 16931-4:2017 (E) 7 15) the need to allow any seller in any European (EU, EE
