# Factur-X / ZUGFeRD MINIMUM

Source: https://xmlvalid.com/schemas/factur-x-minimum

> The smallest Factur-X profile: invoice number, parties and totals.

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.

## Notes

- 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.
