The India GST Invoice Suite for WooCommerce is a build-to-order plugin that ECOSIRE develops, installs and supports directly on your WordPress site — not an instant WordPress.org download. After purchase, our team configures it against your real store, products and seller GSTIN, then hands over a tested, production-ready compliance layer.

The plugin hooks into WooCommerce's order lifecycle (woocommerce_order_status_completed, woocommerce_checkout_order_processed) to auto-generate a GST-compliant PDF invoice the moment an order is placed or marked complete. Each invoice carries your seller GSTIN, the buyer's GSTIN (captured at checkout via a custom billing field), per-line HSN/SAC codes, and a correct CGST/SGST/IGST tax split derived from place-of-supply logic — intra-state orders split into CGST+SGST, inter-state orders apply IGST, exports/SEZ are flagged accordingly.

We map your catalogue's HSN/SAC codes to products via product meta (compatible with simple and variable products), wire GST rate slabs, and store invoice records in custom tables that respect WooCommerce HPOS / custom order tables. A wp-admin settings screen lets you manage seller details, invoice numbering series, and tax rules without touching code. Optional WP-Cron jobs handle monthly invoice sequencing and GSTR-ready export files (CSV/JSON) for your accountant or filing tool.

Built on standard WordPress hooks, actions and filters, the plugin coexists cleanly with your theme, payment gateways and shipping plugins. We can extend it for WPML/multilingual invoices, multisite networks, or push data over the WooCommerce REST API to your ERP. Because ECOSIRE writes and owns the code, every clause is auditable and adjustable as GST rules change.
