vatnode vs VATapp.net

VATapp.net has no API. You open a browser, type a number, read the result. vatnode returns structured JSON with everything your invoicing system needs — in one HTTP call from your code.

VATapp.net shows you this information on screen. vatnode gives it to your application as structured data — ready to store, validate against, and act on programmatically.

Feature Comparison

National registry integrations

When VIES is unavailable or returns no company data, vatnode automatically queries the national business registry. These countries are currently covered:

VATapp.net has no API. When VIES is down for a number you looked up manually, there is no fallback. vatnode's source field tells you which authority answered — VIES, BZST, PRH, SIREN, and so on.

Granular webhook events

Subscribe to any VAT number and get notified the moment something changes — so your customer records and invoice settings stay accurate without manual re-checking.

Actively maintained

EU VAT rules change — Finland raised its standard rate from 24% to 25.5% in September 2024. VATapp.net has no published changelog or maintenance history. vatnode syncs rates daily from the European Commission TEDB. You get the correct rate in every API response, automatically.

Built for compliance — not just validation

Every vatnode response includes a checkId (UUID) and a verifiedAt timestamp. These fields are designed to be stored alongside your invoice records — giving you a documented audit trail that links every invoice to the exact validation event that authorised it.

VATapp.net has no API. A human looks at a result on screen — there is no structured output, no persistent record, and no way to attach evidence of a check to a transaction. For a single spot-check that is fine. For a billing system processing hundreds of invoices, it is not a compliance solution.

Tax authorities across the EU increasingly expect documented validation at the point of transaction — not retroactive checking. vatnode gives your application a machine-readable record for every check: a unique checkId, the exact verifiedAt moment, and the source authority that answered — stored automatically, queryable at any time.
