Factur-X Python library

Factur-X is the e-invoicing standard for France and Germany. The Factur-X specifications are available on the FNFE-MPE website. The Factur-X standard is also called ZUGFeRD 2.0 in Germany.

The main feature of this Python library is to generate Factur-X invoices from a regular PDF invoice and a Factur-X compliant XML file.

This lib provides additionnal features such as:

• extract the Factur-X XML file from a Factur-X PDF invoice,
• check a Factur-X XML file against the official XML Schema Definition.

Some of the features provided by this lib also work for ZUGFeRD 1.0 (the ancestor of the Factur-X standard).

Installation

sudo pip install --upgrade factur-x

Usage

from facturx import generate_facturx

facturx_pdf_invoice = generate_facturx(regular_pdf_invoice, facturx_xml_file)

To have more examples, look at the source code of the command line tools located in the bin subdirectory.
