Teamwant VIES VAT for WooCommerce

The Teamwant VIES VAT for WooCommerce allows you to validate EU VAT numbers in real time using the official VIES service. It supports both B2B and B2C models, providing dynamic VAT behavior based on customer country, VAT validity, shipping address, and more.

This plugin is fully compatible with the new WooCommerce block-based checkout system, as well as the classic (legacy) checkout method.

Key Features:

• Real-time VAT number validation using the VIES system
• Support for both block-based and legacy checkout
• Option to require or make VAT number optional at checkout
• Apply different VAT rates or exemptions for valid VAT numbers
• Periodic CRON-based rechecking of stored VAT numbers
• Detect country code by address if VAT prefix is missing
• Display VAT validation status in order details
• Full OSS VAT support for EU-wide compliance
• Proxy support for large traffic stores
• Integration with shipping VAT rules
• Exclude specific countries (e.g., your base country)
• Logs and validation debug options for transparency

Configuration

The plugin is enabled with default settings after installation. You must configure your tax rules appropriately:

• Set the correct VAT rates under WooCommerce > Settings > Tax
• Choose whether to exempt valid VAT numbers or preserve VAT
• Optionally exclude countries where VAT should not be changed
