Multi-Country VAT/GST E-Invoicing Suite for WooCommerce

Key Features

Multi-jurisdiction e-invoice generation covering ZATCA (KSA), UAE FTA, India GST, Egypt ETA, Italy SDI, Poland KSeF and 20+ markets from one WooCommerce install

Pluggable per-country compliance modules — each regime is an isolated unit you enable per market, so adding a new mandate doesn't touch existing ones

Peppol BIS Billing 3.0 plus national formats: UBL 2.1, FatturaPA XML (SDI), KSeF XML, and GST IRP/IRN JSON generation

Digital signing, QR codes and hash-chaining per regime (e.g. ZATCA cryptographic stamp + QR, India IRN/signed QR)

Per-country Tax-ID / VAT number validation (incl. VIES-style checks) at checkout and at invoice generation

Bilingual and multi-currency invoices via WPML and WooCommerce currency, with RTL Arabic layouts where required

HPOS-aware: reads and writes against WooCommerce High-Performance Order Storage (custom order tables), not just legacy post-meta

Hooks into WooCommerce order lifecycle actions (woocommerce_order_status_completed, woocommerce_new_order) for automatic, real-time invoice issuance

WP-Cron jobs for tax-authority clearance, submission retries and status polling, with admin notices on failures

Dedicated wp-admin settings panel: per-country API credentials, number ranges, templates, and sandbox/production toggles

WooCommerce REST API endpoints plus WordPress filters so your ERP (Odoo, ERPNext, SAP) can pull the signed invoice and clearance status

Audit log and downloadable archive (XML + human-readable PDF) attached to each order for tax-inspection readiness

Multisite-ready: run different country profiles per network site from a single codebase

WooCommerce Subscriptions and refund/credit-note handling that emits the matching corrective document per regime

About this Product

Cross-border WooCommerce merchants face a moving target: ZATCA Phase 2 in Saudi Arabia, UAE FTA's coming e-invoicing mandate, India's GST e-invoice (IRP/IRN) regime, Peppol BIS Billing 3.0 across the EU, Egypt ETA, Italy's SDI/FatturaPA, Poland's KSeF and more — each with its own format, signing rules and clearance flow. Stitching together one plugin per country is fragile and expensive.

The Multi-Country VAT/GST E-Invoicing Suite for WooCommerce is a single, build-to-order plugin that ECOSIRE engineers, installs and supports directly on your WordPress site. It is not an instant download from WooCommerce.com or WordPress.org — it is custom-scoped to the exact jurisdictions you sell into, then deployed and maintained by our team.

At its core is a pluggable country-compliance architecture: each regime is a self-contained module that hooks into WooCommerce order events (via woocommerce_order_status_completed, woocommerce_new_order and related actions) and emits the correct artifact — UBL 2.1 / Peppol BIS 3.0, FatturaPA XML for SDI, KSeF XML, ZATCA-signed XML with QR, or GST IRP JSON — with the right digital signature, hash chain and tax-authority submission.

It is built HPOS-aware (WooCommerce High-Performance Order Storage / custom order tables), respects WPML and multisite for bilingual and multi-currency documents, exposes its own WooCommerce REST API endpoints and WordPress hooks/filters for your ERP, and runs clearance/retry jobs on WP-Cron. Configuration lives in a dedicated wp-admin settings screen — per-country credentials, VAT/Tax-ID validation, number ranges and templates. You own the code on your server; ECOSIRE keeps it compliant as mandates evolve.

What you get

Custom-built plugin scoped to your specific countries/regimes, installed by ECOSIRE on your WordPress/WooCommerce site (staging then production)

Configured wp-admin settings with your per-country tax-authority credentials, number ranges and invoice templates

Sandbox/test-environment validation against each tax authority before go-live (e.g. ZATCA simulation, India IRP sandbox, Peppol test network)

Bilingual / multi-currency invoice templates (XML + PDF) matching each jurisdiction's legal layout

Integration wiring to your ERP or accounting system via WooCommerce REST API and WordPress hooks where required

Technical handover documentation, admin runbook and an architecture overview of the country-module structure

Defined support and compliance-update window so the plugin stays current as mandates change

Who this is for

Cross-Border WooCommerce Operations Lead

Runs a WooCommerce store selling into KSA, UAE, the EU and India and is tired of one disconnected plugin per country. Wants a single suite, HPOS-compatible, that issues compliant e-invoices automatically the moment an order completes.

Finance / Tax Compliance Manager

Accountable for passing ZATCA, FTA, GST and SDI audits. Needs guaranteed-valid signed XML, correct VAT/Tax-ID validation, corrective credit notes, and a clean archive per order — and someone to keep it compliant as deadlines shift.

Technical Lead / Systems Integrator

Owns the WordPress stack and ERP integration. Values clean WordPress hooks/filters, REST API access, multisite/WPML support and a modular country architecture they can reason about, rather than an opaque black-box plugin.

Frequently Asked Questions about Multi-Country VAT/GST E-Invoicing Suite for WooCommerce

How long until the plugin is live on my site? What's the delivery lead time?

This is a build-to-order product, not an instant download. After we confirm scope (which countries/regimes, ERP integrations, multisite/WPML), a typical build runs about 3-6 weeks depending on how many jurisdictions you need and the complexity of each tax authority's onboarding (e.g. ZATCA Phase 2 and India IRP have their own credential and certificate steps). We install on a staging site first, validate against each authority's sandbox, then promote to production with you. We'll give you a firm timeline before you commit.

Do I get ongoing support and compliance updates after delivery?

Yes — that's central to the offer. E-invoicing mandates change constantly (new ZATCA waves, the UAE FTA rollout, Peppol/KSeF schema revisions). Your engagement includes a defined support and compliance-update window during which ECOSIRE keeps the country modules current, fixes issues, and adds schema/format changes pushed by the tax authorities. We can extend support annually. You own the code on your server, so you're never locked out.

Is this available as a one-click install from WooCommerce.com or WordPress.org?

No, and we won't pretend otherwise. It is custom-built and installed by ECOSIRE on your own WordPress/WooCommerce site. There is no marketplace listing to download. This is deliberate: each regime requires your specific tax-authority credentials, certificates and number ranges, which a generic marketplace plugin can't safely ship.

Does it work with HPOS (High-Performance Order Storage) and my existing theme/plugins?

Yes. The suite is built HPOS-aware — it reads and writes against WooCommerce's custom order tables, not just legacy post-meta — and hooks into standard WooCommerce order actions, so it coexists with your theme, payment gateways and WPML. During the build we test against your actual plugin stack on staging and resolve conflicts before go-live.

Which countries and formats are supported, and can you add one that isn't listed?

Out of our existing module library we cover 20+ regimes including ZATCA (KSA), UAE FTA, India GST (IRP/IRN), Egypt ETA, Italy SDI/FatturaPA, Poland KSeF and the EU-wide Peppol BIS Billing 3.0 (UBL 2.1). Because the architecture is pluggable, we can build a new country module for a regime you need that isn't yet in the library — that's quoted as part of your scope.

How are invoices triggered and how does my ERP get the data?

Invoices are generated automatically on WooCommerce order lifecycle events (such as order completion) and submitted to the relevant tax authority via WP-Cron-backed jobs with retry handling. Your ERP or accounting system can pull the signed XML, PDF and clearance status through the plugin's WooCommerce REST API endpoints and WordPress filters, which we wire up to systems like Odoo, ERPNext or SAP during the build.
