عن هذا المنتج
Selling B2B into the EU and UK means you must zero-rate cross-border sales to VAT-registered businesses under the reverse-charge mechanism — but only if you can prove the buyer's VAT number was valid at the moment of sale. WooCommerce core has no VAT-number field, no VIES lookup, and no exemption logic. Merchants typically bolt this on by hand and discover the gap during an audit.
This plugin closes that gap. ECOSIRE builds, installs, and configures it directly on your WordPress site — it is not an instant marketplace download. We tailor it to your tax classes, checkout flow, and theme, then hand over a working, supported system.
What it does on your store: - Adds a VAT number field at WooCommerce checkout and on the My Account / registration screen, placed via woocommerce_after_checkout_billing_form and related hooks so it sits naturally in your billing block. - Calls the EU VIES SOAP service in real time and the HMRC VAT API for GB numbers, returning valid/invalid status plus the registered trader name and country. - Cross-checks the company name and country the buyer entered against the official record so you catch typos and mismatches before the order completes. - When the number is valid and the sale qualifies for reverse charge, it programmatically removes VAT via woocommerce_product_get_tax_class / cart tax filters and shows the correct "VAT reverse-charged" line. - Stores the validation evidence — number, timestamp, VIES consultation reference, and result — against the order in HPOS-compatible order meta, so you have an audit trail.
Built with WP-Cron-safe API handling, caching to respect VIES rate limits, WPML/multisite awareness, and full uninstall hygiene. ECOSIRE owns the build, the install, and ongoing support.

لمن هذا
EU B2B WooCommerce merchant
Sells physical or digital goods to VAT-registered businesses across the EU and needs to legally zero-rate intra-community supplies while keeping proof that each VAT number was valid at the time of sale.
UK store selling cross-border post-Brexit
A GB-based or GB-selling store that must validate both EU (VIES) and UK (HMRC) VAT numbers and apply the right reverse-charge treatment now that the UK sits outside the EU VAT system.
Finance / compliance lead
Owns VAT returns and audit readiness, and wants every exempted order to carry a stored consultation reference and timestamp rather than relying on manual spreadsheet checks.

الأسئلة المتداولة حول VAT Number Validation (VIES) & B2B Exemption
How long until the plugin is live on my store?
Because this is build-to-order, there is a short lead time rather than an instant download. Typical delivery is about 5 to 10 business days from when we have access and your tax-class details, depending on how customized your checkout, theme, and exemption rules are. We confirm a firm date with you before starting and install directly on your WordPress site.
What support and updates are included after delivery?
Each build includes a post-delivery support window for bug fixes and compatibility with the WooCommerce and WordPress versions current at handover. We address issues with VIES/HMRC API changes, checkout conflicts, and HPOS behavior. Longer-term maintenance and feature additions are available as an ongoing arrangement — we will quote that separately so you are never locked into surprise costs.
What happens when the VIES service is down or slow?
VIES has scheduled and unscheduled outages. The plugin is built to fail gracefully: it caches recent valid results, applies a configurable timeout, and can be set to either allow the order to proceed with a flag for staff review or hold exemption until validation succeeds. You choose the strictness in the wp-admin settings so checkout never silently breaks.
Does it handle UK VAT numbers as well as EU ones?
Yes. EU numbers are checked against the VIES SOAP service, and GB numbers are checked against the HMRC VAT Checking API. The plugin applies the correct reverse-charge or zero-rating logic per region, which matters for stores trading between the UK and EU after Brexit.
Is it compatible with HPOS, WPML, and multisite?
Yes. Validation evidence is written using WooCommerce's order CRUD so it works with both HPOS (custom order tables) and legacy post-based orders. The VAT field and messaging are translation-ready for WPML, and the plugin is built to run correctly on a WordPress multisite network if you operate multiple EU storefronts.
Does it guarantee my VAT compliance?
The plugin gives you accurate real-time validation, correct reverse-charge application, and stored audit evidence — the technical foundation auditors look for. It does not replace professional tax advice. Your accountant defines which transactions qualify; the plugin enforces and documents those rules on your store.
