What this tool is
The validator checks a subset of the EN 16931 rule set and reports what it finds. It is a development aid, not a certification, not a conformity statement and not legal or tax advice. Whether an invoice is accepted by a given tax authority or trading partner depends on rules beyond EN 16931, including national CIUS rules and platform requirements. VIZALGO accepts no liability for a business decision taken on the sole basis of a report produced here.
Intellectual property
The site, its copy and its validation engine belong to VIZALGO. The EN 16931 rule identifiers and business-term references quoted in reports come from the standard and its public artefacts.
