Auto-GUS & VIES Checkout Filler for WooCommerce is an enterprise-grade extension providing real-time Polish Ministry of Finance (Biała Lista MF) and European Commission VIES database integration directly in WooCommerce checkout. Automatically validates VAT tax numbers, verifies VAT status, retrieves full company name and address, and auto-fills checkout fields with zero friction.

PL Biała Lista Ministerstwa Finansów

Free official REST API integration querying the live register of VAT taxpayers (wl-api.mf.gov.pl). Validates 10-digit Polish NIP checksum (modulo 11), extracts registered company name, and intelligently parses street, house/apartment number, postal code (XX-XXX), and city.

EU European VIES VAT Validation

Direct REST integration with European Commission VIES database (ec.europa.eu). Automatically handles cross-border B2B purchases for EU member states (DE, CZ, FR, IT, ES, etc.), verifies active VAT status, and parses multiline international addresses.

Key Features:

  • ⚡ WooCommerce HPOS Ready: Fully declared and compatible with High-Performance Order Storage (custom_order_tables) and Cart/Checkout Blocks.
  • 🔍 Dual Integration: Seamlessly supports Classic WooCommerce Checkout ([woocommerce_checkout]) and modern Gutenberg Checkout Blocks.
  • 🛡️ Tax Audit Proof: Stores verified VAT status, source (MF / VIES), verification timestamp, and official MF/VIES Request ID in order metadata.
  • ⚡ Smart Transients Caching: Caches API lookup results for 24 hours using WordPress Transients API to optimize performance and prevent rate limiting.
  • 🚀 Pure Vanilla JavaScript: Lightweight frontend script with zero bloated dependencies, providing animated spinner, status alerts, and instant totals recalculation.
  • 🌐 Automatic Fallback: Automatically switches to European VIES registry if Polish MF servers undergo scheduled maintenance (WL-196).
v1.0.0 Initial Commercial Release for WooCommerce
  • Official Polish White List (MF) Integration: Real-time lookup from wl-api.mf.gov.pl with 10-digit checksum validation (modulo 11 weights).
  • European Commission VIES REST API: Native EU VAT validation for all member states (CZ, DE, FR, IT, ES, etc.) with multiline address parsing.
  • Automated Address Parsing Engine: Splits raw registry addresses into street, house/apartment number, postal code (XX-XXX), and municipality.
  • WooCommerce HPOS & Blocks Compatibility: Fully declared support for Custom Order Tables and Gutenberg Cart/Checkout Blocks.
  • Taxpayer Verification Proof in Orders: Saves VAT status, verification source, timestamp, and official Request ID in order metadata.
  • Admin & Customer Order Visibility: Displays verification badge and query identifier in WP Admin order view, customer order received page, and transactional emails.
  • 24-Hour Transients Cache: Prevents repeated queries and API rate limiting via WordPress Transients API.
  • Offline Fallback Mechanism: Seamlessly switches to VIES validation for Polish entities if Ministry of Finance servers are undergoing scheduled nightly maintenance (WL-196).

Installation & Setup Guide

  1. Download the wp-auto-gus-vies.zip package from your FlexExt account after purchase.
  2. In WordPress Admin, navigate to Plugins → Add New Plugin → Upload Plugin.
  3. Select the downloaded ZIP file and click Install Now, then Activate Plugin.
  4. The plugin automatically registers the NIP / VAT ID field and lookup button in your WooCommerce checkout form. No complicated API keys or paid third-party subscriptions are required!

How It Works in Checkout:

When a customer enters a 10-digit Polish NIP or European VAT number, clicking "Pobierz dane po NIP" (or typing 10 digits) automatically queries the appropriate official government register, verifies the company, and auto-fills Company Name, Street Address, Postal Code, and City.
