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.
