Factur-X / ZUGFeRD MINIMUM
The smallest Factur-X profile: invoice number, parties and totals.
About
MINIMUM holds only the data needed to identify the invoice and book its totals. In Germany it does not count as an electronic invoice on its own.
Two layers are checked: the profile schema, then the profile's Schematron rules with their code lists.
Good to know
- In the validator you can drop the PDF itself: its XML attachment is opened and the profile picked from its specification identifier. So do the API and the command-line client. Rules run only when the document matches the schema.
- The schemas, rules, code lists and example come from the akretion/factur-x library, which ships the official files unchanged.

The validator loads all of these with their folder structure, so includes and imports resolve as published.
Business rules
Schematron · run in this orderThe rules run after the schema check, only when the document matches the schema, and in your browser like the schema check (with SaxonJS by Saxonica). Each finding names its rule, such as BR-CO-15, and the line it points at; each rule has a page with what it checks.

In CI and from code
The same schema by its name, factur-x-minimum, through the API.
npx @xmlvalid/cli validate "**/*.xml" --schema factur-x-minimum
- uses: xmlvalid/validate-action@v1
with:
files: "**/*.xml"
schema: factur-x-minimum
api-key: ${{ secrets.XMLVALID_API_KEY }}
curl https://xmlvalid.com/api/v1/validations \
-H "Authorization: Bearer $XMLVALID_API_KEY" \
-F document={{ $schema->example ?? 'document.xml' }} -F schema=factur-x-minimum
Free accounts get 100 API validations a month. On Pro, a URL monitor can check a published document against this schema every hour and email you when it breaks. More CI setups
