Selling across the EU turns WooCommerce's basic tax tables into a liability. Since the 2021 VAT e-commerce reform, the rate you charge depends on the customer's destination country, your One-Stop-Shop (OSS) registration, and whether the buyer is a VAT-registered business entitled to the reverse charge. WooCommerce core can store flat tax rates, but it cannot validate a VAT number, switch between B2C and B2B logic, track the EUR 10,000 distance-selling threshold, or produce the quarterly OSS return your tax authority expects.
Real-time EU VAT rate selection by ship-to country, applied via WooCommerce tax filters so totals, cart and checkout all stay correct
VIES VAT number validation at checkout (EU SOAP service) with an AJAX field, caching, and graceful fallback when VIES is temporarily down
Automatic B2B reverse charge: valid cross-border VAT numbers zero-rate the order and stamp 'VAT reverse charged' on the invoice
OSS quarterly return exports (CSV/XML) grouped by destination country and rate, ready for your One-Stop-Shop filing
IOSS handling for imported low-value consignments, with the correct rate and IOSS reporting fields
Digital-goods / VAT MOSS logic that taxes electronically supplied services by customer location regardless of distance threshold
This is a build-to-order plugin, not a marketplace download. ECOSIRE designs, builds, installs and supports it directly on your WordPress site. We tailor it to your product mix (physical goods, digital goods/MOSS, or both), your registration state, your invoice format, and your existing checkout and theme.
The plugin hooks into WooCommerce at the right points: a woocommerce_calculated_total / tax filter layer applies the live EU VAT rate by ship-to country, a checkout field plus an AJAX action validates the buyer's VAT number against the EU VIES SOAP service and zero-rates qualifying B2B reverse-charge orders, and a WP-Cron job refreshes rates and rebuilds OSS datasets. Orders are stored cleanly under HPOS (custom order tables) with VAT metadata (rate applied, VIES result, B2B/B2C flag, evidence of customer location) so every line is auditable.
Reporting is first-class: a wp-admin settings screen under WooCommerce lets you export OSS and IOSS returns as CSV/XML grouped by destination country and rate, handle digital-goods VAT MOSS, and emit compliant sequential invoice numbering that never skips or duplicates. It is built to coexist with WPML and multisite stores. You get a documented, single-tenant plugin you own — no per-order SaaS fees.
Ships physical goods from one EU country to consumers across the bloc, has crossed the EUR 10,000 threshold, and needs destination-correct VAT plus a clean OSS return without hiring an accountant to reconcile every quarter.
Sells e-books, templates, plugins or subscriptions to EU consumers where VAT MOSS rules apply from the first sale. Needs customer-location evidence, per-country digital rates and OSS exports that hold up to audit.
Sells to both businesses and consumers, so needs live VIES validation to apply the reverse charge for valid EU VAT numbers while still charging consumers correctly, all stamped on compliant invoices.

This is built to order, so it is not an instant download. A typical build is delivered in about 2 to 3 weeks. We start with a short scoping call to confirm your OSS/IOSS registration, product mix and invoice format, then build and configure the plugin on a staging copy of your site, run test orders against real EU destinations and VIES, and deploy to production after you sign off. Complex multisite or WPML setups may add a few days.
Every build includes a post-launch support window (commonly 30 days) covering bug fixes and adjustments, plus compatibility maintenance for WooCommerce and WordPress core updates during that period. After it ends, we offer an optional care plan that keeps the plugin compatible with new WooCommerce/HPOS and WordPress releases, refreshes VAT rates if EU rates change, and gives you a support channel. You own the plugin code either way.
It charges in real time. The plugin hooks into WooCommerce's tax calculation so the correct destination-country rate is applied live at cart and checkout, B2B orders with a valid VIES number are zero-rated on the spot, and digital goods use customer-location rules. WooCommerce core can only hold static tax-rate tables and cannot validate VAT numbers or build OSS returns.
Yes. It is built against current WooCommerce with HPOS (custom order tables) and is theme-independent because it works through standard WooCommerce hooks and filters rather than editing templates. It is built to coexist with WPML/WooCommerce Multilingual and multisite. During scoping we check for conflicts with subscription, gateway or accounting plugins and adapt the build accordingly.
The export groups taxable sales by destination country and rate and outputs CSV/XML you can use to file your OSS/IOSS return, with full per-order evidence stored for audit. It removes the manual reconciliation work, but it is a compliance tool, not tax advice. We recommend your accountant or tax advisor reviews the first filing; many merchants then file the quarterly return themselves.
Not to build it, but you should register for OSS (or IOSS for imports) before you start filing through it. We configure the plugin to your registration state and the EUR 10,000 distance-selling threshold. If you have not yet crossed the threshold, we set it to charge domestic VAT and switch to destination VAT automatically once you do.
