EU VAT validation
that works when VIES doesn't.
One API to validate VAT IDs, calculate tax, and store audit-proof records. Caching, retry logic, strict company matching. Integrates in 2 minutes.
The Problem
VIES is broken.
You know it. We know it.
The EU's VAT validation system fails when you need it most. Here's what developers deal with every day.
VIES downtime for Germany & Belgium during peak
Error rate on German VAT lookups due to concurrency limits
Some VIES requests take 50+ seconds. In your checkout flow.
SLA from the EU. No uptime guarantee. No support. No fallback.

Features
Everything you need for EU VAT compliance
One API. Validate, calculate, store proof. Stop building VAT logic in-house.
Reliable Validation
Caching, retry with exponential backoff, and circuit breaker pattern. When VIES goes down, we serve cached results. Your checkout never breaks.
Strict Company Matching
Not just "is this VAT ID valid?" but "does it belong to this company?" Name similarity scoring, address normalization, zipcode verification.
Audit-Proof Storage
Every validation timestamped and stored. Export your history for tax audits in one click. The proof your compliance team needs.
VAT Rate Lookup
Current rates for all 27 EU member states. Standard, reduced, super-reduced, zero, exempt. Always up to date.
VAT Calculator
Net to gross with full breakdown. Handles reverse charge, exemptions, and intra-community supply. Integer cents, not floating point.
