Press release

New version of open-source E-invoice validator ZUV will be released for ZUGFeRD 2.1

Frankfurt am Main, Germany, 2020-03-21

Version 0.9 of the e-invoice validator software "ZUV" will be released on Tuesday, March 24, between 3 and 4pm CET. The free download will be available from it's Github site.

The new version supports the new versions of the e-invoicing standards Factur-X 1.0.05 and ZUGFeRD 2.1, which will be released by their respective organizations on the same day.

"Validators" software to syntactically check sample files, are important for formats like Factur-X/ZUGFeRD because they substitute interoperability tests with recipient software. Sample files can be tested once with the validator and do not have to be tested against multiple pieces of recipient software.

Furthermore, e-invoice validators can often automatically check the invoices by re-caculating the amounts.

The free open-source validator "ZUV" already exists since 2017, but it was updated, enhanced and already used systematically in the review process of the release of ZUGFeRD 2.1, that is why it is available from day one. Further details on the changes in this version can be obtained from it's history file.

About ZUV
On 2017-07-24 "ZUV" ("ZUGFeRD and VeraPDF") was released from the makers of the open-source Java ZUGFeRD library Mustangproject. The platform independent tool validates ZUGFeRD 1 und 2.1/Factur-X 1.0.05, does not require internet connectivity and may be used, customized, and integrated for free even in commercial software.

A embedded Open-Source PDF/A Validator from the Open Preservation Foundation, VeraPDF, as well as the official ZUGFeRD Schema- and Schematron files are used in the technical core of ZUV.

ZUV can e.g. be used in the invoice ingesting workflows as well as on servers for automated software builds and tests. E.g. the online interface of the "ZUGFeRD Community" uses ZUV to perform it's validations.

About Factur-X/ZUGFeRD

Factur/X-ZUGFeRD are de facto identical, open European e-invoicing standards. They embeds machine readable UN/CEFACT XML-invoice files in human readable PDF files and can be used in B2B and B2C and, due to their compliance to Directive EU/2014/55 and EN16931, B2G invoices.

The e-invoicing format ZUGFeRD 2.1 will be published by the "Arbeitsgemeinschaft für wirtschaftliche Verwaltung e.V." on March 24, 2020. At the same day the french "Forum National de la Factur Electronique" will issue their updated Factur-X 1.0.05.

So far, the "french edition" Factur-X 1.0 and the "german" ZUGFeRD 2.0 were, despite their different version numbers, technically but not chronologically synchronized.

ZUGFeRD 2.1 now also supports the filename factur-x.xml for the embedded XML. This way, ZUGFeRD 2.1 and Factur-X 1.0.05 are so similar that they are virtually indistinguishable.
