この製品について

GST Invoicing & E-Invoice for India is a build-to-order Shopify app that ECOSIRE designs, builds, installs and supports for your store — it is not an instant App Store download. After purchase, our engineers scope your tax setup, build the app against your store, and hand it over working.

Indian Shopify merchants face a compliance gap: Shopify's native tax engine and order PDFs don't produce legally compliant GST tax invoices, don't handle HSN/SAC line-item classification, and have no path to the Invoice Registration Portal (IRP) for e-invoicing. This app closes that gap.

We connect to your store via OAuth and the Admin GraphQL API, and subscribe to orders/create and orders/paid webhooks. On each qualifying order we generate a sequential, GST-compliant tax invoice carrying your GSTIN, the customer's GSTIN (validated for format and check digit), per-line HSN/SAC codes, and the correct CGST/SGST or IGST split derived from place of supply (intra- vs inter-state). Invoice numbers, tax breakups and document references are persisted in Shopify metafields so they're queryable and survive re-installs.

For B2B and turnover-threshold sellers, the app pushes invoices to the IRP and writes back the IRN and signed QR code onto the PDF and the order record. Credit and debit notes are issued against original invoices with linked references, and you get GST-ready reports (taxable value, tax by rate, by place of supply) exportable for your GSTR filings.

Because every store's catalog, tax registrations and document layout differ, we build to your requirements rather than forcing a generic template. You get a named engineer, source delivered to your store, and an agreed support window. Honest scope: statutory rules change — we keep the app aligned with IRP schema updates during your support term, and quote separately for major regulatory overhauls.

これは誰のためのものですか

Indian D2C brand owner

Sells across multiple states on Shopify and needs every order to produce a legally valid GST invoice with the right CGST/SGST/IGST split, without a manual accountant step per order.

B2B / wholesale Shopify seller

Crosses the e-invoicing turnover threshold or sells to GST-registered buyers and must push each invoice to the IRP and return a valid IRN and signed QR before dispatch.

Finance / compliance manager

Owns GSTR filings and audits; needs clean, sequential invoice numbering, credit/debit-note linkage and exportable tax reports that reconcile with the portal.

GST Invoicing & E-Invoice for India に関するよくある質問

Is this an instant App Store install?

No. This is a build-to-order app. ECOSIRE scopes your GST setup, builds the app against your store, installs it via OAuth and hands it over working. It is not a one-click download from the Shopify App Store.

How long does delivery take?

Typical delivery is 2 to 4 weeks after we confirm scope and receive access. Standard GST invoicing with CGST/SGST/IGST splits ships fastest; full IRP e-invoicing depends on how quickly your GSP/IRP credentials and HSN/SAC catalog mapping are ready.

What do you need from me to enable IRP e-invoicing?

Your active GSTIN(s), registered IRP/GSP API credentials (e-invoice access), and your product catalog so we can map HSN/SAC codes. We integrate against your registered credentials — we do not file on your behalf or bypass any government portal.

Do I get ongoing support and updates?

Yes. Every build includes an agreed support window covering bug fixes and alignment with IRP schema or minor statutory changes during that term. Major regulatory overhauls or new feature requests are quoted separately, and longer support retainers are available.

Will it handle credit notes, exports and reverse-charge correctly?

Yes, where your registrations require them. We build credit/debit notes linked to original invoices, and can add export (LUT/with-tax), SEZ and reverse-charge invoice variants as part of scoping. We confirm exactly which document types you need before building.

Is the data secure and does it stay in my store?

Invoice numbers, IRN, QR codes and tax breakups are stored in your store's Shopify metafields and order records. The app connects over OAuth with least-privilege scopes, and IRP calls use your own registered credentials over secure channels.
