VAT Checker automates intra-Community VAT validation for PrestaShop stores selling to business customers across EU member states. When a customer provides a VAT number at checkout, the module validates it in real time against the official VIES (VAT Information Exchange System) database. If the VAT number is confirmed as valid, the module automatically applies a 0% tax rate to the order — including the invoice — removing the need for manual intervention on cross-border B2B transactions.

• Automatic VIES validation on the delivery address VAT number, with optional company name matching to verify the VAT number belongs to the expected business
• 0% tax applied automatically on verified orders, correctly reflected on the invoice, with the option to also set carrier tax to 0% for qualifying orders
• Per-product exclusions — specific products can be excluded from the 0% tax rule when needed
• Customer group assignment — optionally place customers with a verified VAT number into a designated customer group for further pricing or access rules
• VIES downtime handling — configurable behavior for situations when the VIES database is temporarily unavailable, and a setting to select which address (delivery or invoice) is checked

VAT Checker is an essential compliance tool for PrestaShop merchants in EU countries who sell goods to VAT-registered businesses in other member states. It eliminates manual VAT verification steps and ensures the correct tax treatment is applied consistently on every eligible order. Note: the module checks the shipping address by default, not the invoice address, and 0% tax cannot be applied to shipments within the same country as the merchant's origin country, as configured in the module settings.
