Swiss E-Invoicing using Factur-X (ZugFerd)

We at Grynn have developed a Swiss E-Invoicing App.

The Swiss E-Invoicing standard is based on the French / German ZugFerd Standard, which proposes a HYBRID invoicing which is both human readable and machine readable. What that means an invoice generated in this manner is a PDF file, with an attached XML file.

So this means, no OCR / no guess work / No "machine learning etc is required to take an PDF invoice and feed it to a computer which can unpack this PDF and read the XML file and take the necessary stems to create a purchase invoice on the supplier’s side.

A Factur-x e-invoice will be generated when you submit a Sales Invoice & attached to your Sales Invoice. Everything is automated. Would be great to get a feedback.

  • Version 0.0.1
  • No data transfer to another server, no microservices
  • Based on Factur-x Python Library
  • Integrated into ERPNext
  • Compatible/Tested on v12, v13,
  • Free / Open Source - GPL v3.0 license
  • XML is validated before it is attached

Version 0.0.1. Kindly try it and give us a feedback.


Congratulations to you and your team. Am sure with your keen observation and perfection this will be an excellent app out of the box.

Our app seems to have a valid A/3 and validates using XSD. But the platform is showing some issues. We know the 3-4 issues we have found to make this platform validator happy but haven’t had the time to fix it. Maybe we will look at it in 2-3 weeks. Best

Good job! It is good to see that there is getting more and more traction on these topics in central Europe (refer to also ZUGFeRD and ERPNext) and also the preceding implementations of QR-invoice and ZUGFeRD in in one combine all-in-one module (including bank integration along ISO 20022).
