Description

GST Report for WooCommerce is a lightweight, fast admin dashboard built entirely with native PHP and direct database queries. It generates GST-compliant reports for Indian WooCommerce stores, handles both intra-state (CGST + SGST) and inter-state (IGST) tax calculations across 18% and 5% GST rates, and lets you export to Excel or open a PDF tax invoice in one click — all without leaving WordPress admin.

Designed for Indian store owners who need to file GSTR-1, GSTR-3B, or provide tax invoices to B2B buyers, without the overhead of a full accounting plugin.

Key Features

Setup Wizard — On first activation, a guided wizard checks your HSN codes, GST tax rates, and PDF Invoices plugin configuration so your dashboard is accurate from day one.
GST Report tab — Line-item breakdown per order with CGST/SGST (intra-state) and IGST (inter-state) at 18%, 5%, and 0% rates, with separate columns for each. Cancelled and refunded orders appear as negative entries.
Orders tab — Card-based order view showing customer name, GSTIN, billing state, order status, and a full per-order GST breakdown (CGST, SGST, IGST).
Products tab — All published products with thumbnail, SKU, HSN code, price, stock quantity, GST rate, and stock status.
Excel export — Download the filtered report as a properly formatted .xlsx file using a zero-dependency PHP XLSX writer. Includes date, invoice number, DC number, customer, GSTIN, state, HSN, quantity, subtotal, and all GST columns.
PDF invoice — Opens the WooCommerce PDF Invoices & Packing Slips invoice for any order in a new tab with one click. Access key is read automatically from the order — no manual configuration needed.
Flexible HSN lookup — Reads HSN from product meta (hsn, _hsn_code), product attributes (any attribute whose name contains “HSN”), or order-item meta — whichever is present. Checks variation first, then parent product.
HPOS compatible — Works with both the classic wp_posts order table and WooCommerce High-Performance Order Storage (HPOS/COT). Detects automatically.
Filtering & search — Filter by start/end date, sort newest or oldest, search by order ID or billing email. Paginated at 50 orders per page.
Summary stat cards — Total orders, total products, revenue, total GST collected, and average order value — calculated via a single SQL aggregation query (no N+1 queries).

Who Is This For?

Indian WooCommerce store owners filing GSTR-1 or GSTR-3B returns
Stores selling to GST-registered buyers (B2B) who need tax invoices with GSTIN
Accountants or store managers who need a quick Excel export of GST data for a given period
Stores in Tamil Nadu (TN) needing CGST + SGST split, or any other state needing IGST

How GST Calculation Works

The plugin uses WooCommerce’s own tax totals stored against each order line item:

Intra-state (TN): If billing state is Tamil Nadu, tax is split 50/50 as CGST + SGST.
Inter-state: All other billing states are treated as IGST.
5% GST: Products assigned to a tax class whose name contains 5 (e.g. “GST 5%”) are reported under the 5% columns.
18% GST: All other taxed products are reported under the 18% columns.
0% / Exempt: Products with no tax are reported under the zero-rated supply column.

Technical Notes

Pure PHP — no JavaScript frameworks, no React, no REST API.
All data fetched via WC_Order_Query and direct SQL with $wpdb->prepare().
All $_GET input is sanitised with sanitize_key(), sanitize_text_field(), absint(), and wp_unslash().
All output escaped with esc_html(), esc_url(), esc_attr(), wp_kses_post().
Stats query result cached with wp_cache_get/set.
Nonce-protected on all export actions.

FAQ

Does the plugin work right after activation?

Yes. The Setup Wizard runs automatically on first activation and guides you through three checks: HSN codes, GST tax rates, and PDF Invoices plugin. After completing the wizard, the GST dashboard is ready to use.

How does the plugin determine CGST/SGST vs IGST?

The plugin reads the billing state of each order. If the billing state is TN (Tamil Nadu), the tax is split equally as CGST + SGST (intra-state). All other billing states are treated as IGST (inter-state). To change the home state, edit the is_tn() method in includes/class-gst-calculator.php.

How do I set the HSN code for my products?

Go to Products Edit Product and add a custom field with the key hsn (or _hsn_code) and the HSN code as the value. Alternatively, add a product attribute whose name contains “HSN” (e.g. “HSN Code”, “HSN/SAC”). The plugin checks variations first, then the parent product.

How do I mark a product as 5% GST?

Assign a WooCommerce tax class whose name contains 5 (e.g. “GST 5%”, “5 Percent”) to the product. The default tax class and all other classes are treated as 18% GST.

The Invoice button is not working. What should I do?

Make sure PDF Invoices & Packing Slips for WooCommerce is installed and active.
Go to WooCommerce PDF Invoices Debug File System & Access.
Set Document link access type to Full and save.
Invoice buttons will now open PDF invoices in a new tab directly from the GST dashboard.

Does the plugin support WooCommerce HPOS (High-Performance Order Storage)?

Yes. The plugin automatically detects whether HPOS is enabled and adjusts its SQL stats query between the wc_orders table (HPOS) and the classic wp_posts / wp_postmeta tables accordingly.

Can I filter the Excel export by date range?

Yes. Apply the date filters on the GST Report page, then click Export Excel. The exported .xlsx file will contain only the orders matching the active filter.

Does the plugin work with variable products?

Yes. The HSN code lookup checks the specific variation first (more precise), then falls back to the parent product if no HSN is found on the variation.

Can I search for a specific order in the dashboard?

Yes. Use the Search field to find orders by Order ID (numeric) or Billing Email. The search applies to all three tabs and to the Excel export.

Does the plugin store any customer data?

No. The plugin only reads WooCommerce order and product data that already exists in your database. It does not create, modify, or transmit any customer data.

Is the plugin compatible with multisite?

The plugin is designed for single-site WooCommerce installations. Multisite compatibility has not been tested.
