Selling digital goods or SaaS across borders means WooCommerce core can't keep up: it ships flat, manual tax tables, no concept of EU VAT MOSS/OSS thresholds, no reverse-charge logic, and no compliant invoice numbering. Quaderno-Style Global Tax & Invoicing for WooCommerce is a custom plugin ECOSIRE builds to your store's exact rules — a Quaderno-class tax and invoicing engine that lives inside your own WordPress install, with no third-party SaaS subscription required.
Worldwide automatic tax determination at checkout (EU VAT, UK VAT, GST for AU/NZ/IN/CA, US sales tax) keyed off billing country, IP geolocation, and product tax class via woocommerce_calculate_totals and tax-class filters
Compliant invoice and receipt generation as a locked, gap-free sequential custom post type, rendered to PDF and delivered through WooCommerce transactional email on woocommerce_order_status_completed
Automatic credit notes / refund documents generated when an order is refunded or partially refunded, keeping your audit trail consistent
B2B reverse-charge handling with live VIES VAT-number validation for EU buyers, applying the correct 0% rate and statutory exemption wording on the invoice
Per-country registration-threshold tracking via a scheduled WP-Cron job (EU OSS €10,000, UK, and US economic-nexus thresholds) with wp-admin dashboard warnings before you cross
Multi-currency, multi-jurisdiction tax reporting with CSV export grouped by country and tax type for VAT/OSS returns and sales-tax filings
At checkout, the plugin hooks into woocommerce_calculate_totals and woocommerce_product_get_tax_class to determine the correct rate from the customer's billing/IP country, product type, and B2B status — applying VAT, GST, or US sales tax automatically. For B2B EU orders it runs VIES VAT-number validation and applies reverse-charge with the right exemption note. Every paid order triggers a sequential, gap-free compliant invoice (custom post type, locked numbering) rendered to PDF and emailed via WooCommerce's transactional mail, with credit notes on refund.
It is HPOS-aware (custom order tables), works with WPML/Polylang for multilingual invoices, and is multisite-friendly. A WP-Cron job tracks your registration-threshold progress per country (e.g. EU OSS €10,000, UK, US economic nexus) and warns before you cross. Tax and revenue reports export per jurisdiction (CSV) for filing.
ECOSIRE builds, installs, and configures this on your site, then provides ongoing support and rate-table updates. It is not an instant marketplace download — it is engineered to your catalog, gateways, and the countries you actually sell into. Tax determination is software, not legal advice — final filings stay with your accountant.
Sells ebooks, templates, plugins, or downloads worldwide on WooCommerce and is now liable for EU VAT, UK VAT, and other place-of-supply rules they can't track manually.
Runs recurring billing via WooCommerce Subscriptions and needs correct tax on renewals, B2B reverse-charge, and clean compliant invoices for every billing cycle.
Owns VAT/OSS and sales-tax filings, wants per-jurisdiction reports, threshold alerts, and gap-free invoice numbering instead of reconciling spreadsheets each quarter.

This is built to order. After a short scoping call to confirm the countries you sell into, your gateways, and whether you use HPOS, WPML, or Subscriptions, ECOSIRE typically delivers a configured, staging-tested build in about 2 to 4 weeks. We install and verify it on a staging copy of your site first, then schedule production go-live with you. There is no marketplace link — you receive the plugin installed and working on your own WordPress site.
Every build includes a post-launch support window for bug fixes and configuration help, plus periodic tax-rate-table updates as jurisdictions change rates or thresholds. We test compatibility against new WooCommerce and WordPress releases (including HPOS changes) and can extend support under a maintenance arrangement. Because the plugin lives on your server with no third-party SaaS dependency, there is no per-transaction or monthly tax-engine fee.
Yes. The plugin is built HPOS-aware (it reads and writes the custom order tables and falls back to legacy post-meta when HPOS is off), generates localized invoices through WPML or Polylang, and hooks into WooCommerce Subscriptions renewal events so tax is recalculated correctly on each renewal. We confirm your exact extension stack during scoping.
It automates tax determination, compliant invoice numbering, reverse-charge logic, and per-jurisdiction reporting based on the rules and registrations you provide. It is software, not legal or accounting advice. We configure it to current rules and keep rate tables updated, but registering for VAT/GST, validating thresholds, and submitting returns remain the responsibility of you and your accountant.
Yes. For B2B EU orders the plugin validates the buyer's VAT number against the VIES service at checkout, and when valid applies the reverse-charge mechanism — a 0% rate with the correct statutory exemption note printed on the invoice. Invalid or missing numbers fall back to standard destination-country VAT so you stay compliant either way.
Tax determination runs on the existing WooCommerce totals calculation, and heavy work like threshold tracking and report aggregation is offloaded to a scheduled WP-Cron job rather than the checkout request. VIES lookups are cached to avoid repeated external calls. On a properly hosted store the customer-facing checkout impact is negligible.
