Simplify Indian GST calculation, invoicing, and compliance
Manage Goods and Services Tax compliance directly inside your WooCommerce store without relying on external billing software or manual spreadsheets. India GST Tax Suite for WooCommerce handles intrastate and interstate tax calculation, B2B GSTIN verification, sequential PDF invoicing, refund credit notes, bulk HSN management, and CSV reporting in one unified e-commerce workflow.
The extension integrates natively into WooCommerce > Settings > India GST, Analytics > GST Analytics, and WooCommerce > Status > GST Compliance, so you and your accounting team always work inside familiar WordPress and WooCommerce screens.
Key features
Automated CGST, SGST, IGST, and UTGST calculations
- Place of supply detection: The tax engine evaluates your store state against the customer billing or shipping state to apply CGST and SGST for intrastate orders or IGST for interstate orders, with full support for Indian Union Territories (UTGST).
- Bidirectional WooCommerce tax synchronization: Sync Indian GST slabs (0%, 5%, 12%, 18%, and 28%) directly with native WooCommerce tax tables so WooCommerce calculations remain the single source of truth.
- Flexible pricing support: Configure tax calculations for prices that include GST, exclude GST, or vary per product.
- Non-Indian base location handling: If your store base sits outside India, the extension alerts you clearly in settings while supporting multi-currency export invoices.
B2B checkout and statutory field validation
- Classic checkout and Checkout Blocks compatibility: Collect customer GSTINs and business names seamlessly across both legacy shortcodes and modern WooCommerce Checkout Blocks.
- Statutory Luhn Mod-36 checksum verification: Validate 15-character GSTINs, 10-character PAN numbers, 6-digit postal PIN codes, state selections, emails, and phone numbers in settings and at checkout before saving invalid tax identifiers.
Sequential PDF tax invoices and credit notes
- Financial-year sequential numbering: Customize invoice and credit note prefixes and patterns with dynamic placeholders such as
{prefix}, {fy}, {fy_long}, {number}, {year}, and {month}, plus optional automatic number resets every April 1.
- Refund-linked credit notes: Generate GST credit notes automatically from WooCommerce refund line items, preserving exact CGST, SGST, IGST, and tax rate breakdowns.
- Custom PDF branding and previews: Add your business logo and authorized signature image, choose a PDF accent color, include custom terms or bank details in the footer, and preview sample invoices and credit notes directly inside settings before going live.
- Automated email and account access: Attach tax invoices to order processing or completed emails, attach credit notes to refund emails, and let customers download verified GST documents from their My Account orders screen.
Bulk HSN and SAC catalog management
- Per-product tax metadata: Assign HSN or SAC codes, GST rate slabs, and tax categories inside each WooCommerce product under the General product data tab.
- Timeout-safe batch updates: Assign HSN/SAC codes and GST rates across an entire product category or your whole store catalog. A confirmation dialog verifies your intent before running, and AJAX batching (50 products per batch) with a live progress bar prevents server timeouts on large catalogs.
Native WooCommerce Analytics and compliance auditing
- WooCommerce Analytics integration: View total sales, taxable sales, CGST, SGST/UTGST, IGST, invoice counts, and credit note totals under Analytics > GST Analytics with custom date pickers and Indian financial-year presets.
- System status compliance checks: Monitor missing HSN codes, unassigned GST rates, missing high-value B2B GSTINs, invoice numbering sequence gaps, and tax mismatches under WooCommerce > Status > GST Compliance.
- Actionable guidance: Proactive admin notices alert you to open critical compliance findings, and a dedicated Suggested Fix column explains what requires attention and links directly to the affected setting or product.
Searchable invoice registry and empty-safe CSV exports
- Filterable invoice registry: Search invoices by number, customer name, or GSTIN, filter by Indian financial year, sort columns, and paginate cleanly inside settings.
- Empty-safe CSV exports: Download CSV reports for sales invoices, HSN summaries, state-wise breakdowns, customer GST summaries, product GST totals, and GSTR return summaries. Export options validate available invoice records first so you never generate empty CSV files.
