What is VIES and Why Does It Matter for Your Invoices?

VIES (VAT Information Exchange System) is the EU's centralized database for verifying VAT IDs across 27 member states. It allows businesses to confirm a customer's VAT registration status instantly.

In our app, simply enter a VAT ID (e.g., DE123456789) in the customer detail form, and our system queries the official VIES API for real-time validation. This confirms if the ID is valid or invalid. In case of technical downtime, results may be temporarily unavailable, enabling correct VAT treatment on invoices.

For sellers and providers, this is crucial for intra-EU B2B transactions, where a valid VAT ID allows zero-rating under the reverse charge mechanism.

Why VAT Validation is Essential for Sellers and Providers

Compliance

Meet EU rules for zero-rating invoices (Directive 2006/112/EC); avoid significant fines and tax assessments during audits (amounts vary by member state).

Financial Protection

Confirm buyer legitimacy to reclaim input VAT and prevent fraud (e.g., carousel schemes costing EU €50B/year).

Efficiency

Automate checks in customer details, reducing errors in invoice generation (e.g., via ZUGFeRD exports).

Risk Reduction

Real-time status cards flag issues before saving, ensuring clean data for accounting integrations (e.g., Clockify).
