Key points

What the buyer sees

Checkout gets optional GSTIN and business name fields. The buyer sees the invoice in the account and through a link in the e-mail, and can save it as PDF from the browser.

What the admin gets

The GSTR-1 screen shows the tables of the period, row counts, taxable value and tax, plus warnings before filing: for example, the kind of tax on an order differs from the place of supply.

How much it costs

The base version is free. Pro costs 990 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, WooCommerce 8.9+, PHP 7.4+.
  • GST registration and WooCommerce taxes set up.
  • HSN codes from the portal list: the official tool blanks unknown codes.

Full module description

GST Invoice & GSTR-1 is for a WooCommerce store registered under GST in India. Each paid order gets a numbered tax invoice, each refund a credit note, and the documents of the month turn into files for GSTR-1.

This is software, not tax advice. You choose the GST rate and the HSN or SAC of each product. The plugin holds no rate table, so agree them with your tax consultant.

What the buyer sees

Checkout gets optional GSTIN and business name fields. The buyer sees the invoice in the account and through a link in the e-mail, and can save it as PDF from the browser.

What the admin gets

The GSTR-1 screen shows the tables of the period, row counts, taxable value and tax, plus warnings before filing: for example, the kind of tax on an order differs from the place of supply. You download CSV by section from there, and in Pro the portal JSON and all PDFs of the period.

How it works, step by step

  1. You enter your GSTIN, State and numbering.
  2. You set HSN or SAC on products.
  3. The plugin finds the place of supply: CGST and SGST, or IGST.
  4. A paid order gets an invoice, a refund gets a credit note.
  5. Each month you download the files for GSTR-1.

Under the hood

  • The portal format changes: the version sits in data, and the screen warns after 120 days.
  • For a service to a buyer with a GSTIN in another State, WooCommerce charges by billing State. The plugin reports by the GSTIN State and flags the mismatch without changing the tax.
  • Other place of supply cases of sections 12(3)–(14) and 13 are not built.
  • Above 5 crore turnover e-invoicing is needed, and the plugin does not do it.

How to install

  1. Plugins → Add New → Upload Plugin: pick the zip and activate.
  2. WooCommerce → GST India → Settings: enter your GSTIN, State and numbering.
  3. Fill in HSN or SAC on products.
  4. Place a test order and check the invoice.
  5. For Pro: paste the key or start the 7-day trial.

@catcode_support Setup, compatibility, activation
Does the plugin choose the GST rate?

No, you choose the rate and code.

Does it file GSTR-1 on the portal?

No. It prepares the files, and you upload them.

Is the GSTIN checked?

Only the pattern and check digit, not whether it is active.

Can I change an issued invoice?

No, the document is frozen. There is cancellation and a credit note.
