PD CEN/TS 16931 is a series that discusses standards for electronic invoicing(e-invoicing). PD CEN/TS 16931‑7 is a part of multi-series electronic invoicing that focuses on methodology for the development and use of EN 16931-1 compliant structured Core Invoice Usage Specifications (CIUS). A “Core Invoice Usage Specification” (CIUS) is a specification that provides a seller with detailed guidance, explanations and examples, as well as rules (business rules) related to the actual implementation and use of structured information elements present in the core invoice model in a specific trading situation.
PD CEN/TS 16931‑7 establishes requirements for the steps to be taken in the process of creating Core Invoice Usage Specifications (CIUS) to avoid unnecessary proliferation and fragmentation in the use of CIUSs.
Also, PD CEN/TS 16931‑7 provides you with guidance for the creation and implementation of CIUSs with a quality control objective.
PD CEN/TS 16931‑7 on electronic invoicing is useful for:
The purpose of a Core Invoice Usage Specifications (CIUS) is to clarify how certain information elements in an invoice instance shall be used, for example by further restricting, mandating, or specifying how elements shall be used. It is necessary to define a clear set of criteria with which a CIUS will comply before the CIUS can be registered in the appropriate registry.
PD CEN/TS 16931‑7 provides you with guidance on the creation and implementation of CIUS and the necessary tools and procedures to facilitate the creation/maintenance of a CIUS with a quality control objective.
PD CEN/TS 16931‑7 describes how an invoice instance can comply. The invoice must respect all rules (both syntactical and semantic), and also can respect additional rules which have been specified in a CIUS. PD CEN/TS 16931‑7 specifies how a sending or receiving party can comply. A receiver may claim compliance to the standard if he accepts invoices that comply with the core invoice model with a CIUS.
PD CEN/TS 16931‑7 gives recommendations to use the machine-processable format of CIUS to avoid unnecessary proliferation and to guide the implementation, publication of CIUSs in a registry.
