 This project provides a `LibreOffice <https://www.libreoffice.org/>`_ Extension to generate `Factur-X <http://fnfe-mpe.org/factur-x/>`_ invoices from a spreadsheet. This extension provides a Python macro that can generate a PDF Factur-X invoice or refund at the Minimum profile. These invoices are compatible with `Chorus Pro <https://chorus-pro.gouv.fr/>`_, the e-invoicing plateform of the French administration.
 
-The aim of this project is to allow small companies that don't have an ERP or invoicing software to generate state-of-the-art electronic invoices. With this LibreOffice extension, we can now say that the generation of Factur-X invoices is not limited to companies with a modern ERP: even a one-person company without any IT background can generate a Factur-X invoice with a simple spreadsheet. And they can do it at no cost using free software only!
