Most Shopify stores selling across borders hit the same wall: Shopify charges tax at checkout but does not issue legally compliant tax invoices. Merchants in the EU, UK, GCC, India, Australia, and beyond are left manually building invoices that meet local VAT/GST formatting rules — sequential numbering, supplier tax IDs, reverse-charge notes, and per-country mandatory fields.
Automatic invoice generation triggered by Shopify orders/create and orders/paid webhooks via the Admin GraphQL API
Automatic credit-note generation on refunds/create webhooks, referencing the original invoice number
Country-specific VAT/GST rule sets (EU VAT, UK VAT, GCC VAT, India GST, Australia GST, and more) with the mandatory fields each jurisdiction requires
Sequential, gap-free invoice and credit-note numbering persisted in shop metafields to survive redeploys
Multi-currency rendering using the order's presentment currency, with tax totals shown in both presentment and shop currency where required
Multi-language invoice templates driven by the customer locale on the order
The Global VAT/GST Invoice Generator for Shopify is a custom app that ECOSIRE builds, installs, and supports for your specific store. It subscribes to Shopify's orders/create, orders/paid, and refunds/create webhooks, reads full order and tax-line data through the Admin GraphQL API, and produces a compliant PDF invoice — or a credit note when a refund is issued — automatically.
This is not an instant App Store download. After purchase, our team scopes your tax jurisdictions and branding, builds the app against your store, installs it via a custom OAuth app connection, and validates real invoices before handover. Typical delivery is 5–7 business days.
Key capabilities include country-specific VAT/GST rule sets, multi-currency and multi-language rendering driven by the order's presentment currency and customer locale, sequential gap-free invoice numbering stored in store metafields, branded A4/Letter templates matching your identity, and bulk export and email delivery for accountants and audits.
Because it is purpose-built, the app fits your tax setup rather than forcing you into a generic template. ECOSIRE owns the build end to end — you get clean, documented code on your Shopify Partner-managed app, plus ongoing support. The $99 one-time price covers the build and installation; no per-invoice metering.
Sells from one Shopify store into multiple VAT/GST territories and needs every order to produce a legally compliant invoice without manual work or a third-party accounting platform.
Owns month-end and audit prep; needs gap-free sequential numbering, correct reverse-charge handling, and a bulk export of all invoices and credit notes for a period.
Wants a purpose-built, owned solution that fits the store's exact tax setup and branding rather than a generic App Store app with per-invoice fees and rigid templates.

Typical delivery is 5–7 business days. After purchase we scope your tax jurisdictions and branding, build the app against your store, install it via a custom OAuth connection, subscribe the order and refund webhooks, and validate real invoices with you before handover. This is a build-to-order service, not an instant Shopify App Store download.
The $99 covers the build, installation, and an initial support window for fixes and adjustments. Because ECOSIRE builds and owns the code end to end, we also offer ongoing support and updates — for example when a country changes its VAT/GST invoice rules or you add a new sales territory. We will quote any larger feature additions separately and transparently.
No. Shopify calculates and charges tax at checkout and shows it on the order, but it does not produce a legally compliant tax invoice with sequential numbering, supplier tax IDs, reverse-charge notes, and the per-country mandatory fields auditors require. This app fills that gap automatically.
We configure the rule sets for the jurisdictions you actually sell into — common ones include EU VAT, UK VAT, GCC VAT, India GST, and Australia GST. Each has its own mandatory invoice fields and formatting, which we set up and validate during the build. Tell us your markets and we confirm coverage before we start.
Numbering is persisted in your shop's metafields rather than in ephemeral app state, so invoice and credit-note numbers stay gap-free across redeploys and refunds. Each credit note references its original invoice number, which keeps your audit trail clean.
No. The price is a one-time build fee. There is no per-invoice metering and no revenue share. The app runs on your store against the Shopify Admin GraphQL API and webhooks you already have access to.
