The ZUGFeRD library allows to create XML files as required by German electronic invoice initiative ZUGFeRD as well invoices in the successor Factur-X. One special profile of Factur-X is the German XRechnung format. The library is meant to be as simple as possible, however it is not straight forward to use as the resulting XML file contains a complete invoice in XML format. Please take a look at the ZUGFeRD-Test project to find sample creation code. This code creates the same XML file as shipped with the ZUGFeRD information package.

Tests and writing support for ZUGFeRD invoices are still missing.
More examples will come soon.
