PP VAT Checker is a reliable PrestaShop module that automates VAT number verification for your business customers. With direct integration with the VIES database, it checks the entered details while the address is being completed, reducing mistakes and typos before they reach your orders.
It is a strong fit for B2B and B2B/B2C stores that need to apply the 0% VAT rate safely to eligible intra-EU business sales. Simple configuration, full control over product-level exceptions, and far less manual invoice correction.
You get a more reliable checkout flow: the module guides customers when they make a mistake, while the final validation still happens on the server side. Fast, secure and aligned with day-to-day tax handling.
Information Parameters:
This module is a strong fit for e-commerce businesses selling internationally and serving company buyers. It works especially well for stores that want to automate intra-EU B2B VAT handling, avoid chasing customers about incorrect VAT numbers after the order is placed, and keep flexibility through precise control over product-level VAT exceptions.
You stay in control of how strictly the store validates business customers and which tax rule should be applied to verified EU buyers.
Your team can immediately see whether a VAT number was accepted and, if not, why it failed.
Not every item in your catalogue should qualify for 0% VAT. Manage those exceptions directly on the product.
The customer sees straight away whether the entered number matches the selected country, making it easier to fix issues at the earliest step.
The module does not rely only on browser-side scripts. The final validation happens securely on the store server.
A well-structured B2B checkout matters. Although the module works quietly in the background, it has a real impact on the buying experience for business customers. A smoother basket flow with fewer tax-related errors helps build confidence, while your team spends less time on invoice corrections, VAT disputes and manual order handling.
Before installation or update, we recommend creating a full backup of the store files and database. If your shop uses a custom checkout module such as One Page Checkout or its own product class overrides, confirm compatibility of the vat_number field and the Product.php override responsible for switching the 0% VAT rule before going live.
