We validate against XRechnung 2.3 and 3.0. Our rulesets are updated within 48 hours of official KoSIT releases.

Structural errors like missing mandatory fields, invalid code values, or incorrect namespace declarations are auto-fixed. Business decisions (e.g., missing Leitweg-ID) require your input.
