ZugFerd or UGL for PDF Invoices

[fufiderheld]

I am in Austria, and there is the ZufFerd Standard vor digital invoices really common. Maybe we could implement that into the PDFs? That would be really awesome :-)
Maybe we have also different digital Invoices Types we could implement.

@fufiderheld i'm not known with this standard, can you please provide me with some documentation?

[fufiderheld]

Sure, I will provide you some data :-)
Just give me some time, you need it in english?

[evilguy4000]

would be easier but not necessary.

[evilguy4000]

@fufiderheld I've been checking, but wouldn't it be more wise to be completely PEPPOL compliant, since all european countries are moving towards this platform for e-invoices.

[fufiderheld]

Well Peppol is as far as I understand it a data transfer system and zugferd is a user system that allows user (Because its a normal PDF) to read the invoice and IN the PDF is a xml in which the invoice data is digital (like Invoice number, Date, ....) and as far as I understand it, you can send via peppol also ZugFerd Invoices. So I guess these are two pairs of shoes, or?
I know, because I am working with it every day (we are transforming invoice workflows in companies via docuware and jobrouter) in Austria and Germany ZugFerd is by far the most common digital invoice type.

[evilguy4000]

I did some more research, apparently Peppol does not use it's own embedded XML format, but the XML format in the invoices needs to be EN 16931compliant, what ZugFerd does!.
Will get on this!

@fufiderheld can you checkin the latest version ?

[fufiderheld]

Thx, I will check in the next days :-)

[fufiderheld]

maybe I am blind, but i updated to 4.20 but can't find it to configure (maybe there isn't any) and when I download the PDF there isn't any xml in the pdf. So maybe I am searching wrong? Do I have to create the Invoice again?

[evilguy4000]

it is in the settings:

[fufiderheld]

My bad, I scrolled over it three times ^^

@fufiderheld can you then check please the attached/included Zugferd xml file if it's correct? e.g. https://www.b2brouter.net/de/zugferd-validator-e-rechnungen-einfach-online-pruefen/ Thanks

[fufiderheld]

So I think we have a few things to do.

First the PDF needs to be PDF/A-3

there is an xml with peppool recognized:

These Errors are in German, maybe I will find something in english an better to be copied:

On that website https://app.b2brouter.net/de/validation (thanks @Heart1010 ) you can click on the error and view it where it is in the xml.

I always used that side for xml ZugFerd validation:

@fufiderheld @Heart1010
Can you check with the latest version?

[evilguy4000]

@fufiderheld Can you validate with the latest version?

[fufiderheld]

Ähm there is no new version. Or maybe I am to fast ^^
But at 2 am my ansible will update it.
I'll wait till tomorrow.

Or is there something hanging in github?

[fufiderheld]

I was toooooo fast, sry. ^^

[fufiderheld]

we have now a xml again, but still not PDF 3A compliant AND not ZuGFerd compliant, AND i found a program to validate it :-)
here is the report
INV-20260301-006 (1)_result.pdf

and here is the PDF3A compliance report:
Validation Report_02.03.2026.html
