Stop relying on manual VAT checks.
Vatidator validates customers and vendors directly in your ERP, blocks risky postings, and preserves tamper-evident audit proof, at the moment of invoicing.
Invalid, missing, or outdated VAT data shouldn't reach posting.
Zero-rated B2B invoicing depends on valid VAT numbers. Catch the gap before posting, not in an audit.
VAT numbers verified by hand on a portal, long after the master record was created.
Nothing stops a document from posting against an invalid or outdated VAT number.
When the tax authority asks, there's no reliable record of what was checked, and when.
Validate. Apply policy. Preserve proof.
Three steps, all inside Business Central, no portals, no spreadsheets, no separate validation tool.
Validate
Every customer and vendor VAT number is checked against official registries and country-specific sources, as the record is created and before it posts.
Apply policy
Configurable posting controls block or warn on invalid, missing, or stale VAT data, per document type and entity.
Preserve proof
Each result is stored as a timestamped, tamper-evident proof record, ready for audit without manual preparation.
Everything VAT compliance needs, in one extension.
No third-party tools. No data leaving your ERP for manual lookups.
Validate your entire customer and vendor base in one run.
Run validation across every entity at once, see valid, invalid and stale results side by side, and let automatic stale detection flag numbers that need re-checking after a configurable period.
Stop risky documents before they post.
Block or warn on sales and purchase documents when a VAT number is invalid, missing, or unchecked. Policies are configurable per document type and entity, so controls match your risk appetite.
Every validation leaves a tamper-evident record.
Each check is stored with a timestamp, source, and a retrievable proof identifier secured with hash-chain integrity. When an audit comes, the evidence is already there, no scramble, no reconstruction.

Check a single customer or vendor directly from the card.
