About this Product

Selling across borders means every order can fall under a different invoicing rulebook — EU VAT, UK VAT, Gulf VAT, Australian/NZ GST, Indian GST, and more. Shopify's native order receipts and confirmation emails are not legally compliant tax invoices in most of these jurisdictions: they lack the required sequential invoice numbering, supplier/buyer tax IDs, per-rate tax breakdowns, and the reverse-charge language B2B buyers demand.

Global VAT/GST Invoicing & Tax Compliance is a Shopify app that ECOSIRE custom-builds, installs on your store, and supports — it is not an instant App Store download. After purchase we collect your store details, legal entities, and per-country invoice requirements, then build the app to fit your catalog and tax registrations.

Once live, the app listens to Shopify order/create and order/paid webhooks, reads the order through the Admin GraphQL API (line items, taxLines, shipping, presentment currency), and generates a compliant tax invoice per country with a gapless sequential number, your VAT/GST registration numbers, and a clean per-rate tax summary. At checkout or in the customer portal we capture the buyer's VAT/tax-ID (validated and stored in order metafields), so B2B and reverse-charge orders are documented correctly. Invoices render in the customer's currency and language, and the correct tax rate is applied and shown based on order destination and product tax class.

For your finance team, every invoice is archived and downloadable, with bulk PDF and CSV export filtered by date, country, or tax rate — ready to hand to an accountant or import into Xero, QuickBooks, or Odoo. Because we build it for your entities, registrations, and templates, you avoid the per-document fees and template limits of generic invoice apps. ECOSIRE owns delivery, install, and ongoing support and updates as tax rules change.

Frequently Asked Questions about Global VAT/GST Invoicing & Tax Compliance

Isn't Shopify's order confirmation already a tax invoice?

No. In most VAT/GST jurisdictions a compliant tax invoice must include a gapless sequential invoice number, the supplier's tax-registration number, the buyer's tax ID where applicable, and a per-rate tax breakdown — Shopify's native receipts and confirmation emails omit several of these. This app generates a document that meets each destination country's requirements.

How long does delivery take, since this is build-to-order?

This is not an instant App Store install. After purchase we collect your store details, legal entities, and the countries you need to cover. A typical build, install, and review cycle runs about 2 to 4 weeks depending on how many jurisdictions and templates are involved. You get progress checkpoints and a final walkthrough before go-live.

What about ongoing support and updates when tax rules change?

ECOSIRE owns ongoing support. We fix issues, adjust templates, and update per-country tax logic as rates and rules change. Support terms are agreed during onboarding; the one-time build price covers delivery and an initial support window, with optional retainer beyond it.

Will it handle multiple currencies and languages?

Yes. The app reads the order's presentment currency from the Admin GraphQL API and renders the invoice in that currency, adding exchange-rate notes where a jurisdiction requires them. Invoice templates are produced in the languages you need and matched to the customer's locale.

Can my accountant export everything for VAT/GST filing?

Yes. Every invoice is archived and downloadable, and the bulk export tool produces PDFs and a CSV filtered by date range, country, or tax rate. The CSV is structured for import into Xero, QuickBooks, or Odoo, so your accountant can reconcile and file without re-keying data.
