The most complete solution to handle billing details for B2C and B2B customers worldwide. Fully compatible with both the classic WooCommerce checkout and the modern WooCommerce Blocks / Store API.

Full Compatibility: Classic & Blocks

We designed this plugin to be future-proof. Whether you are using a legacy theme or the new Gutenberg-based checkout, GG Checkout International integrates natively:

• WooCommerce Blocks: Fields are injected via Store API, updating labels and validation rules in real-time without reloading the page.
• Classic Checkout: 100% compatible with shortcode-based checkouts and all major themes (Astra, WoodMart, Storefront, etc.).

Flexible Operating Modes

Choose how you want to collect fiscal data based on your target audience:

1. Individual / Company Selector: Perfect for mixed stores. A dropdown toggles relevant fields.
2. "Request Invoice?" Checkbox: Keeps the checkout clean; fields only appear if requested.
3. B2B Only Mode: Treats every customer as a business, making company fields mandatory by default.

Frequently Asked Questions

Does it support Intra-EU tax exemption?

Yes. If a customer provides a valid EU VAT number (verified via VIES), the plugin can automatically remove VAT from the order total based on your tax settings.

What happens if the VIES service is down?

The checkout is not blocked. You can configure the plugin to allow the order to proceed to avoid losing sales during temporary downtime of official government services.
