TechTrade VAT Check verifies your vendors' EU VAT IDs against the official VIES system — with name and address matching, the official consultation number and a stored, printable proof document (English, German or Russian). Exactly what you need to invoice B2B vendors net under reverse charge, in any EU country.
A plain "valid" from a free online checker is worthless at audit time. TechTrade VAT Check performs the qualified VIES consultation (Art. 31 of Council Regulation (EU) No 904/2010), stores the consultation number and proof document with the vendor's certification, keeps a clear per-vendor tax status and automatically re-checks every vendor on schedule. German marketplace operators additionally get the BZSt qualified confirmation (§ 18e UStG) built in.
Key features
- Qualified VIES consultation for all EU countries via the official REST API — name/address matching plus the official consultation number as audit evidence.
- Proof document in English, German or Russian — the header automatically carries your shop name and domain.
- Bonus for German taxpayers: BZSt qualified confirmation (§ 18e UStG) built in.
- Swiss UID register (uid.admin.ch) for CHE numbers; optional HMRC lookup for GB.
- Per-vendor tax status as a single source of truth: reverse_charge_ok · vat_required · invalid · non_eu · pending.
- Proof stored with the vendor certification — result, consultation number, request date.
- Automatic re-checks every N months plus one-click "Re-check all due".
- Test check without saving — verify any VAT ID with name/address matching.
- Vendor dashboard notices: vendors see their own VAT status and fix bad entries themselves.
- Audit-safe: own data table, nothing is dropped on uninstall.
Requirements: CS-Cart Multi-Vendor 4.20+, a vendor profile field holding the VAT ID, your own VAT number as requester. PHP SOAP for Swiss checks.
