Selling into 20+ tax jurisdictions exposes a hard truth: WooCommerce core tax tables are static. You upload rate CSVs, set standard/reduced/zero classes by hand, and pray the EU, UK, GCC and US rates haven't moved. WooCommerce Global VAT & Tax Automation replaces that manual grind with a custom-built plugin that ECOSIRE designs, installs and maintains directly on your WordPress site.
Real-time tax rate determination by country, region, postcode and VAT/GST status via WooCommerce checkout hooks (`woocommerce_calculate_totals`)
EU B2B reverse-charge handling with live VIES VAT-number validation and audit-logged validation results
Automatic VAT/GST-compliant PDF invoices with region-specific mandatory fields, sequential numbering and reverse-charge notices
Distance-selling threshold and US economic nexus tracking with wp-admin dashboard alerts before you cross a registration line
Multi-currency tax handling that resolves the taxable amount in the order currency and stores the exchange basis in order meta
EU OSS quarterly reporting and IOSS (≤ €150 consignment) data export as accountant-ready CSV
The plugin hooks into the WooCommerce cart and checkout pipeline (woocommerce_calculate_totals, woocommerce_cart_tax_totals, woocommerce_checkout_order_processed) to determine the correct rate in real time from the customer's billing/shipping country, region, postcode and VAT/GST number — including reverse-charge for validated B2B EU sales via VIES. Tax classes, rounding mode (per-line vs per-total) and price-inclusive/exclusive display are resolved per market, not globally.
Because it is built for your stack, it is HPOS / custom order tables aware, stores compliance metadata in order meta, and renders VAT/GST-compliant invoices as PDFs with the legally required fields per region. A scheduled WP-Cron job refreshes rate tables and watches your distance-selling thresholds and US economic nexus so you know before you cross a registration line, not after.
EU sellers get OSS/IOSS-ready reporting — quarterly One-Stop-Shop summaries and the IOSS consignment data (≤ €150) exported as CSV. Reports are exposed through a dedicated wp-admin screen and the WooCommerce REST API so your accountant or external filing tool can pull them. WPML and multisite configurations are supported when your build needs them. You own the code; ECOSIRE supports it.
Ships physical goods from one base into the EU, UK and GCC and keeps tripping over moving VAT/GST rates and OSS thresholds in WooCommerce core's static tax tables.
Needs defensible OSS/IOSS reporting, correct B2B reverse-charge via VIES, and compliant invoices they can hand to their accountant without monthly spreadsheet rework.
Runs HPOS-enabled, possibly WPML/multisite stores for clients and wants a tax engine that lives in their own codebase with named support rather than a black-box SaaS subscription.

This is built-to-order, not an instant download. After we confirm your jurisdictions, tax classes and invoice requirements, a typical build runs about 2 to 4 weeks depending on how many markets and edge cases (reverse-charge, IOSS, multisite) are involved. We need staging access to your WordPress/WooCommerce site, your current tax setup, and sample products. We develop on staging, run live test orders, then deploy to production.
Every build includes a defined post-launch support and update window agreed in writing before we start. During that window ECOSIRE handles bug fixes, WooCommerce/WordPress compatibility updates and adjustments when a covered jurisdiction changes its rules. You own the plugin code on your own server, so you are never locked into a subscription to keep it running. Extended support or new-market additions can be scoped as follow-on work.
The plugin automates calculation, invoicing and reporting accurately for the jurisdictions we build it for, and it flags threshold and nexus crossings. It does not replace your accountant or file returns for you. You remain responsible for registering in each market and submitting filings; the OSS/IOSS and per-region reports are designed to make that filing straightforward.
Yes. We build against High-Performance Order Storage (custom order tables) and write compliance data to order meta so it stays consistent with WooCommerce's modern storage. WPML and multisite are supported when your build requires them. During scoping we review your active plugins and gateways so the tax engine integrates cleanly with checkout and invoicing rather than conflicting with them.
Off-the-shelf tax plugins are generic and often tie you to a metered third-party rate API and recurring fees. We build a plugin tailored to your exact markets, your invoice rules and your stack, installed in your own codebase. Where a SaaS rate service genuinely helps, we can integrate one, but the logic, reporting and support stay yours and stay scoped to how you actually sell.
