**WARNING**: there is an alternative implementation of Factur-X in the module **account_edi_ubl_cii** of the official addons. If both modules are installed, the XML embedded in the PDF is the XML generated by the module **account_edi_ubl_cii**. To avoid that, you need to uninstall the module **account_edi_ubl_cii**.

This module requires a recent version of the Python library `factur-x <https://github.com/akretion/factur-x>`__ developped by Akretion. Note that the factur-x library depends on PyPDF2 for the low-level PDF manipulation. To install it, run:

.. code::

  pip3 install --upgrade factur-x
