Cross-border invoices, validated live.
Reverse-charge isn't optional when you invoice a German agency or a Dutch B2B customer. Validate a counterparty's EU VAT ID against the live VIES registry, surface the registered company name, and flag the entry as reverse-charge — with the proof stored for audit.
Paste a VAT ID, watch it resolve.
Type or paste an EU VAT ID. Baslic hits VIES live and returns the registered company name, address, and a verified-at timestamp. If the ID is invalid, you see why — instantly.
Typical lookup: ~400 ms. Cached for 24h — re-validating the same counterparty within a day is free.

Four things most apps skip.
Live, not stale
Every VIES check is a fresh live call. A 6-month-old check doesn't satisfy a Finnish auditor — and it doesn't satisfy us.
Cached audit proof
VIES response, company name, address, and verified-at timestamp are stored with the invoice. Your auditor can replay the validation a year later.
Reverse-charge automation
Valid VIES + EU service invoice → 0% VAT + 'käännetty verovelvollisuus' note applied, with the rule behind it.
Country-aware
Knows the VAT ID format quirks: GR uses EL, NL has the C/P suffix, IT has 11 digits. Validates locally before hitting VIES — saves API calls.
All 27 EU members.
Every member state's VAT ID format is supported, validated locally, and verified live against VIES. UK, NO, CH, US counterparties — handled separately as non-EU exports (0% with proof attached).

Selling to EU consumers? OSS — on the roadmap.
Under the EU OSS scheme, B2C goods to consumers in other EU countries get the customer's country VAT once you cross €10,000 / year. Automatic threshold tracking and quarterly-return prep are on our roadmap — today we flag OSS lines so you handle them manually.
Send your first EU B2B invoice — validated.
Try it on a real counterparty. VIES check in ~400 ms, reverse-charge attached, audit proof stored.
