EU VAT guide
Batch VAT validation
Batch VAT validation is useful for finance, billing, marketplaces, and onboarding teams that need to check many EU VAT IDs.
What a good batch flow needs
CSV import, country-aware format checks, queued VIES requests, retries for temporary errors, and clear export statuses.
Invalid, unavailable, timeout, and rate-limit responses should remain separate columns or states.
Privacy and audit records
Teams may need validation evidence, but storage should be explicit and scoped to the user's compliance need.
A lightweight checker can avoid retention; a paid batch product should offer retention settings and downloadable evidence.
