About this Product
Selling into many tax jurisdictions exposes a hard truth about Shopify: the platform charges tax correctly at checkout, but it does not produce the compliant tax invoice each country's law demands. The Gulf wants a bilingual TRN-stamped invoice with a ZATCA-style QR; the EU wants sequential numbering and a valid VAT number with reverse-charge wording; the UK wants its own VAT-invoice format; India wants a GST invoice with HSN codes and an IRN/QR from the IRP; and APAC markets each have their own GST rules. Bolting five separate plugins together creates reconciliation chaos.
VAT/GST Multi-Country Invoicing is a single Shopify app, custom-built by ECOSIRE for your store. It subscribes to the orders/create and orders/paid webhooks, reads the full order (line items, tax lines, customer, shipping and billing addresses) over the Admin GraphQL API, then resolves the correct country tax profile from the buyer's location and your registration footprint. The app writes invoice numbers, IRNs/QR payloads and compliance status back to order metafields so your data stays inside Shopify and survives theme or app changes.
This is build-to-order, not an instant App Store install. After purchase we scope your country list, registrations and document templates, then build, deploy and connect the app to your store via OAuth — including any e-invoice clearance integrations (ZATCA, India IRP, Peppol where applicable). You receive a working, branded, installed app plus documentation. We handle hosting, the app's webhook reliability and ongoing rule updates as tax regimes change. Pricing is a one-time build fee; what you get is a system that matches your jurisdictions, not a generic template you have to wrestle into compliance.
What you get
- A fully custom Shopify app built for your store and installed via OAuth, scoped to your specific countries and registrations
- Configured per-country tax invoice templates (legal layout, language, currency, QR/IRN placement) for each jurisdiction you sell into
- Connected live e-invoice clearance integrations (e.g. ZATCA, India IRP, Peppol) wired to your credentials and tested in their sandbox/staging environments
- Webhook subscriptions (orders/create, orders/paid, refunds/create) and metafield definitions provisioned on your store
- Consolidated tax-reporting export plus a short admin handbook covering invoice numbering, reissue and reconciliation
- Deployment to ECOSIRE-managed hosting with monitoring, plus source-aware documentation and a handover walkthrough
Who this is for
Cross-border DTC brand operator
Sells one catalog into the GCC, EU and UK and keeps getting compliance complaints because Shopify charges the right tax but never produces a legally formatted VAT invoice per country.
Finance / tax manager at a scaling merchant
Owns VAT/GST filings across multiple registrations and needs gap-free sequential invoices, valid tax-ID capture and a single consolidated report per jurisdiction instead of reconciling five disconnected plugins.
India + APAC marketplace seller
Requires GST invoices with HSN codes and a valid IRN/QR from the IRP for B2B orders, alongside other APAC GST formats, and wants it generated automatically from each Shopify order without manual portal uploads.

Frequently Asked Questions about VAT/GST Multi-Country Invoicing
How long does it take to get the app, and how is it delivered?
This is a build-to-order app, not an instant App Store download. After purchase we run a short scoping call to confirm your countries, registrations and template requirements, then build and install it. A typical single-to-few-country build is roughly 2 to 4 weeks; configurations that need live e-invoice clearance (ZATCA, India IRP, Peppol) take longer because of each authority's sandbox onboarding and credential approval. We give you a firm timeline after scoping and install it on your store via OAuth ourselves.
Do I get ongoing support and updates as tax rules change?
Yes. Tax regimes change — rates move, new e-invoicing phases go live, formats get revised. ECOSIRE hosts and operates the app's backend, keeps the webhook pipeline reliable, and ships rule and template updates for the jurisdictions in your build. The one-time fee covers the build, installation and an initial support window; we offer a continuing maintenance arrangement for ongoing rule updates and new-country additions, quoted separately so you only pay for the markets you actually use.
Does this replace Shopify's tax calculation at checkout?
No, and it shouldn't. Shopify (and Shopify Tax / Avalara where you use it) still calculates and charges tax at checkout. Our app reads the resulting order and its tax lines over the Admin GraphQL API and produces the compliant invoice document and any e-invoice clearance that Shopify does not generate. It is the invoicing and compliance layer on top of your existing tax setup, not a replacement for it.
Which countries and e-invoice systems are supported?
The build targets the markets you actually sell into across the GCC, EU, UK, India and APAC. Template-level support (correct legal layout, language, numbering, tax-ID validation) applies broadly across these regions. Live e-invoice clearance is integrated where a government mandate and an API exist — for example ZATCA Phase 2 in Saudi Arabia, the IRP for India IRN/QR, and Peppol-based networks in the EU. We confirm exactly which clearance integrations are in scope during scoping.
Where does my invoice data live, and is it secure?
Invoice numbers, IRN/QR payloads, clearance status and PDF references are written back to your order and customer metafields, so the compliance data lives inside your own Shopify store and survives theme or app changes. The app installs with least-privilege OAuth scopes (read orders, write metafields) and runs on ECOSIRE-managed hosting. We do not require access you don't need, and credentials for e-invoice authorities are stored against your account, not shared.
