EU VAT, OSS & IOSS Compliance for WooCommerce is a custom plugin that ECOSIRE builds, installs, and maintains on your own WordPress site — it is not an instant WordPress.org or WooCommerce.com download. You purchase the build, we scope your country mix and tax setup, then deliver a tested plugin wired into your live store.
Destination-based B2C VAT rates for all 27 EU member states, applied via WooCommerce tax hooks (woocommerce_product_get_tax_class, woocommerce_calculated_total) at cart and checkout
Real-time B2B VAT number validation against the EU VIES SOAP service, with graceful fallback and caching when VIES is temporarily unavailable
Automatic zero-rated reverse-charge handling for valid cross-border B2B orders, including the legally required 'VAT reverse charge' invoice annotation
€10,000 distance-sales threshold monitor that tracks rolling cross-border B2C turnover and warns in wp-admin when you must register for OSS
OSS (One Stop Shop) quarterly CSV report generation, grouped by destination country and VAT rate, ready for your national tax portal
IOSS (Import One Stop Shop) monthly CSV report generation for sub-€150 imports into the EU
Since the 2021 EU VAT reform, WooCommerce core only handles flat tax tables — it cannot determine the destination-based B2C rate for all 27 member states, validate a buyer's VAT number, or produce the quarterly OSS and monthly IOSS filings your accountant needs. This plugin closes that gap.
At checkout it resolves the customer's shipping country and applies the correct standard or reduced VAT rate for that destination, recalculating totals through standard WooCommerce tax hooks (woocommerce_product_get_tax_class, woocommerce_calculated_total). For B2B orders it calls the EU VIES SOAP service to validate the entered VAT number in real time; a valid cross-border number triggers a zero-rated reverse-charge line with the legally required invoice note.
A built-in €10,000 distance-sales threshold monitor tracks your rolling cross-border B2C turnover and flags when you cross into mandatory OSS territory. The plugin stores per-order VAT evidence (IP country, billing country, rate applied) and exports OSS and IOSS CSV reports ready for your tax portal. Live ECB exchange rates convert non-EUR sales for accurate VAT base amounts.
Built for HPOS (High-Performance Order Storage), WPML-compatible, and delivered with documentation. ECOSIRE handles installation, a staging-first rollout, and ongoing updates as VAT rules change.
Sells physical goods from one EU country to consumers across the bloc, has crossed (or is nearing) the €10,000 distance-sales threshold, and needs correct destination VAT plus quarterly OSS reporting without hiring a developer in-house.
Ships to VAT-registered businesses across the EU and must validate VAT numbers through VIES and apply reverse-charge zero-rating correctly, with audit-ready evidence on every invoice.
Sells downloads, courses or subscriptions where EU place-of-supply rules tax at the buyer's location from the first sale, and needs IOSS-aware reporting and ECB currency conversion baked into checkout.

No. This is a build-to-order plugin. ECOSIRE scopes your country mix and tax model, builds the plugin to fit, and installs it on your WordPress site. You are buying a built-and-installed solution plus support, not a self-service marketplace download.
Typical delivery is 2 to 3 weeks from the kickoff call, depending on how many EU destinations, product types, and B2B rules you need. Simpler single-country-of-origin B2C setups are faster; complex mixed digital/physical and multisite stores take longer. We confirm a firm timeline during scoping.
When a customer enters an EU VAT number at checkout, the plugin calls the official EU VIES SOAP web service to confirm the number is valid and registered. If valid and cross-border, the order is zero-rated as a reverse charge with the required invoice note. VIES results are cached and the plugin degrades gracefully if the EU service is temporarily down.
Yes. Delivery includes a post-launch support window for bug fixes, and EU rate tables plus ECB exchange rates refresh automatically via WP-Cron. When VAT rules or rates change at the policy level, ECOSIRE can ship plugin updates under a support or retainer arrangement so your store stays compliant.
Yes. The plugin is built for WooCommerce High-Performance Order Storage and reads and writes order data through the WooCommerce CRUD layer, not direct post meta. It is WPML and multisite compatible, and because the VAT logic runs through standard WooCommerce tax and checkout hooks, it works alongside your existing theme and most checkout setups.
No. The plugin charges correct VAT and generates the OSS and IOSS CSV reports you or your accountant submit to the tax portal. You still need to register for OSS/IOSS where required and file the returns. It removes the manual calculation and data-gathering work, not the legal filing obligation.
