About this Product

India GST E-Invoicing & E-Way Bill for WooCommerce is a build-to-order plugin that wires your store directly into India's GST e-invoicing system. When an order reaches a status you choose (for example processing or completed), the plugin builds the government JSON schema (INV-1.1) payload from the WooCommerce order, posts it to the IRP via your chosen GSP/ASP API, and writes back the IRN, signed invoice, and signed QR code as order meta — then renders a compliant tax invoice PDF.

This is not an instant marketplace download. ECOSIRE builds the plugin against your GSTIN, your GSP credentials, your tax setup and theme, then installs and configures it on your WordPress/WooCommerce site and supports it afterwards. That means it works with HPOS (High-Performance Order Storage), your existing tax classes, and your hosting — no generic guesswork.

Core logic handles the parts merchants get wrong: CGST/SGST vs IGST split based on supplier and place-of-supply state codes, HSN/SAC mapping per product, GSTIN format validation (and optional GSTN lookup), and reverse-charge / B2B vs B2C distinctions. E-way bills are generated for consignments over the threshold, pulling transporter ID, distance and vehicle number from fields added to wp-admin.

Built on first-class WordPress primitives: order-status hooks/actions, a settings screen under WooCommerce → Settings, WP-Cron retry queue for transient IRP outages, and an audit log of every API call. We can extend it for WPML/multilingual invoices, multisite, multi-GSTIN sellers, and bulk back-fill of historic orders. You receive the full source, deployment to staging then production, and a defined support window.

What you get

A custom WooCommerce plugin built against your GSTIN, GSP/ASP credentials and tax configuration

Installation and configuration on your WordPress site (staging first, then production) by an ECOSIRE engineer

GSP/ASP API integration wired to your chosen provider in sandbox, then switched to production after sign-off

HSN/SAC mapping for your catalogue plus CGST/SGST/IGST tax-class setup verified against sample orders

Compliant GST tax invoice PDF template and e-way bill workflow matched to your branding

Full plugin source code, a configuration runbook, and an admin walkthrough of generation, cancellation and retries

A defined post-launch support and bug-fix window, with compliance updates as the IRP schema evolves

Who this is for

Indian D2C / online retailer above the e-invoicing threshold

A WooCommerce store that has crossed the GST e-invoicing turnover threshold and now legally must register IRNs. They need invoices and e-way bills generated automatically at order time instead of re-keying every order into the government portal.

B2B WooCommerce seller shipping across states

A wholesaler or manufacturer selling to GST-registered buyers nationwide. They need correct IGST vs CGST/SGST handling, GSTIN validation on B2B orders, and e-way bills produced for every inter-state consignment over the limit.

Finance / compliance lead at a growing WooCommerce business

The person answerable for GST returns and audits. They want every order's IRN, signed QR and audit trail stored against the order, accurate HSN-wise tax summaries, and a reliable retry path so no invoice is ever missed during IRP downtime.

Frequently Asked Questions about India GST E-Invoicing & E-Way Bill for WooCommerce

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

Typical delivery is around 2 to 4 weeks from the point we have your GSP/ASP sandbox credentials, GSTIN details and catalogue. We build against your store, test in the IRP sandbox with sample orders, deploy to your staging site for sign-off, then switch to production. Timelines move with scope add-ons like WPML invoices, multisite or multi-GSTIN setups — we confirm a firm date in writing before starting.

What ongoing support and updates are included?

Every build includes a defined post-launch support window for bug fixes and configuration help, plus compliance updates when the government changes the IRP JSON schema or e-way bill rules. Because we install and own the deployment with you, we can patch directly on your site. After the included window, ongoing maintenance is available as an optional retainer.

Do I need my own GSP/ASP account and IRP credentials?

Yes. E-invoicing requires a GST Suvidha Provider / ASP relationship and IRP API credentials registered to your GSTIN — the plugin authenticates as you. We work with your chosen GSP, integrate against their sandbox first, and help you move to production. We do not resell IRP access, so your data and credentials stay yours.

Will this work with HPOS and my existing theme and plugins?

Yes. The plugin is built for WooCommerce High-Performance Order Storage (custom order tables) as well as the legacy post-meta model, and it hooks into standard order-status actions rather than overriding your theme. During the build we test it against your live plugin stack on staging and resolve any conflicts before going to production.

What happens if the IRP or GSP API is down when an order comes in?

Generation never blocks the customer's checkout. Failed or pending submissions go into a WP-Cron retry queue with back-off, and every attempt is recorded in an admin audit log. You can also re-trigger IRN or e-way bill generation manually from the order screen, so nothing is silently lost during government downtime.

Can it handle IRN cancellation and credit notes?

Yes. IRNs can be cancelled within the government's 24-hour window directly from the WooCommerce order screen, and the plugin supports credit-note (CDN) documents for returns and refunds so your e-invoice records stay consistent with your accounting.
