Key Features

One-click e-invoice (IRN) generation for B2B orders: submits invoice JSON to the IRP via your GSP and returns the IRN plus IRP-signed QR code

GSTIN validation (format + checksum) for store and B2B customers, with a per-rate tax breakup printed on every invoice

GSTR-1 (B2B / B2C / HSN summary) and GSTR-3B preparation exports in CSV/JSON for reconciliation and portal upload

GST-compliant PDF tax invoice as a custom post type with sequential, financial-year-aware numbering (resets each FY)

WP-Cron automation to batch-push eligible B2B orders to the IRP without manual clicks, with retry on transient IRP failures

About this Product

India GST Invoice & E-Invoice (IRN) Suite is a build-to-order WooCommerce plugin for GST-registered Indian sellers and the accountants who file their returns. This is not an instant download from WooCommerce.com or WordPress.org — ECOSIRE builds, configures, installs and supports it directly on your WordPress site, then hands it over running against your live store and your IRP/GSP credentials.

The suite hooks into WooCommerce order lifecycle actions (woocommerce_order_status_completed, woocommerce_checkout_order_processed) to generate a GST-compliant tax invoice as a custom post type, with sequential, financial-year-aware invoice numbering. For B2B orders carrying a buyer GSTIN, a single click (or an automated WP-Cron job) submits the invoice JSON to the Invoice Registration Portal (IRP) through your chosen GSP, returns the IRN and signed QR code, and stamps both onto the PDF.

Tax is computed by place-of-supply: intra-state orders split into CGST + SGST, inter-state into IGST, derived from the store state and the customer's shipping/billing state. Products carry 8-digit HSN / SAC codes (with a bulk-assignment screen for your catalogue), and every invoice shows a per-rate tax breakup and validated GSTIN.

For filing, the suite produces GSTR-1 (B2B, B2C, HSN summary) and GSTR-3B preparation exports your accountant can reconcile and upload. It is HPOS-aware (works with WooCommerce custom order tables and the legacy posts store), respects WordPress roles/capabilities for who can issue or cancel an IRN, and exposes filters so your developers can override numbering, templates or the JSON payload. Scope, IRP/GSP wiring and edge cases are confirmed with you before the build — you get a plugin tuned to your store, not a generic one.

Frequently Asked Questions about India GST Invoice & E-Invoice (IRN) Suite for WooCommerce

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

Typical delivery is 2 to 4 weeks from the kickoff call, depending on catalogue size and how your GSP/IRP access is set up. We confirm scope, your store state rules and HSN mapping first, build against the IRP sandbox, smoke-test on a staging copy of your site, then install and activate on production with you watching. There is no instant marketplace download — you are getting a plugin configured to your store.

What do I need to have ready before you start?

You need an active GST registration with your store GSTIN, e-invoicing enabled for your business (mandatory above the current turnover threshold), and access to an IRP-registered GSP or the NIC e-invoice portal API credentials. We also need admin access to your WordPress/WooCommerce site (ideally a staging clone) and your current HSN/SAC list if you have one — if not, we help build it.

Does this work with HPOS and my existing theme and gateways?

Yes. The plugin is built HPOS-aware, so it reads orders from WooCommerce custom order tables and falls back to the legacy posts store on older installs. It hooks into standard WooCommerce order actions, so it is independent of your theme and payment gateways — Razorpay, PayU, Stripe, COD and others all flow the same way once the order is placed.

Who handles IRP errors, GST schema changes and ongoing updates?

ECOSIRE supports the plugin after handover. Your build includes a support and maintenance window for bug fixes and IRP/GSP schema changes; when the government updates the e-invoice JSON schema or HSN rules, we ship an update to your site. Ongoing support beyond the initial window is available as a maintenance plan — we will not leave you with an unmaintained plugin when the GSTN changes the spec.

Can it cancel an IRN or issue a credit note?

Yes. IRN cancellation is supported within the IRP's 24-hour window, and credit notes are handled as separate documents that reference the original IRN. Both actions are gated by WordPress capabilities, so only roles you authorise can cancel an e-invoice, and every request and IRP response is written to an audit log.

Will my GSTR-1 and GSTR-3B exports match what my accountant files?

We configure the GSTR-1 (B2B, B2C, HSN summary) and GSTR-3B preparation exports to your accountant's workflow during the build, and validate the figures against a sample filing period before sign-off. The exports are CSV/JSON intended for reconciliation and portal upload — your accountant remains in control of the final return; the plugin removes the re-keying.
