E-invoice rule our own check at ARLing, not from a schematron
ARL-DATUM-PORADIE: The payment due date (…) is earlier than
The payment due date (…) is earlier than the issue date (2026-09-11).
Original wording of the rule
This is our own check, not a rule from a schematron. That is why no external wording is quoted here.
How to fix it
- Open the XML file and find the element
cbc:DueDate. - Add or correct the element the way the wording of the rule above asks for.
- Save the file and check it again with our checker. It runs in your browser, the file is never uploaded.
A correct UBL 2.1 snippet
<cbc:DueDate
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">2026-09-25</cbc:DueDate>The snippet is only the part of the document the rule is about. Put it in the right place inside your invoice; the namespaces are written here only so that the snippet reads on its own.

Our check is not complete: we do not check the XSD schema and we do not implement every rule, and a file that passes says nothing about whether the buyer or the Peppol network will accept it. Licences for the quoted wordings are listed in our sources.
