Factur-X: electronic invoicing standard for Germany & France

Project description

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 in English and French. 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).


This library works both on python 2.7 and python 3.

To install it for python 3, run:

sudo pip3 install --upgrade factur-x

To install it for python 2.7, run:

sudo pip install --upgrade factur-x


from facturx import generate_facturx_from_file

facturx_pdf_invoice = generate_facturx_from_file(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.

Command line tools

Several command line tools are provided with this lib:

  • facturx-pdfgen: generate a Factur-X PDF invoice from a regular PDF invoice and an XML file
  • facturx-pdfextractxml: extract the Factur-X XML file from a Factur-X PDF invoice
  • facturx-xmlcheck: check a Factur-X XML file against the official Factur-X XML Schema Definition

All these commande line tools have a -h option that explains how to use them and shows all the available options.


This project also provides a webservice to generate a Factur-X invoice from a regular PDF invoice, the factur-x.xml file and additional attachments (if any). This webservice runs on Python3 and uses Flask. To run the webservice, run facturx-webservice available in the bin subdirectory of the project. To query the webservice, you must send an HTTP POST request in multipart/form-data using the following keys:

  • pdf -> PDF invoice (required)
  • xml -> factur-x.xml file (any profile, required)
  • attachment1 -> First attachment (optional)
  • attachment2 -> Second attachment (optional)

It is recommended to run the webservice behind an HTTPS/HTTP proxy such as Nginx or Apache. You will certainly have to increase the default maximum upload size (default value is only 1MB under Nginx!): use the parameter client_max_body_size for Nginx and LimitRequestBody for Apache.

You can use curl, a command line tool to send HTTP requests (on Linux Ubuntu/Debian, just install the curl package) to generate the request:

curl -X POST -F 'pdf=@/home/me/invoice.pdf' -F 'xml=@/home/me/factur-x.xml' -F 'attachment1=@/home/me/purchase_order.pdf' -o /home/me/facturx_invoice.pdf

A public instance of this webservice is available on a server of FNFE-MPE at the URL


This library is published under the BSD licence (same licence as PyPDF4 on which this lib depends).
