关于此产品
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.
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.

这是给谁的
Cross-border EU D2C store owner
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.
B2B WooCommerce wholesaler
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.
Digital products / SaaS seller
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.

关于EU VAT, OSS & IOSS Compliance的常见问题
Is this an instant download from WooCommerce.com or WordPress.org?
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.
How long does delivery take after I purchase?
Typical delivery is one working week 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.
How does the VIES B2B validation actually work?
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.
Do I get ongoing support and updates as EU VAT rules change?
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.
Will it work with HPOS, WPML and my existing theme?
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.
Does this replace my accountant or tax registration?
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.
