📦 You bought it. Here's how to use it.

5-minute setup. First invoice in 30 seconds.

If you got the licence email, you're already 60% done. The rest is just unzipping, pointing Claude at the folder, and asking for an invoice.

1

Download the plugin zip ~30 sec

Open the licence email we sent right after your purchase (sender: hello@gstinvoice.app, subject: "Your GST Invoice Generator licence").

Click the green "Download plugin" button inside. It downloads a file like gst-invoice-generator-v1.1.0.zip (~25 KB).

Can't find the email? Check spam first. Still missing? Email hello@gstinvoice.app with your purchase order ID — we'll resend within 1 working hour.
2

Unzip the file ~10 sec

On Mac: Double-click the zip in Finder. macOS auto-extracts it next to the zip → you'll see a folder named gst-invoice-generator-plugin/.

On Windows: Right-click the zip → Extract All → click Extract. Same folder appears.

Tip: Move that folder to a permanent spot like ~/Documents/gst-invoice-generator-plugin/ so you don't lose it after Downloads cleanup.
3

Install the plugin in Claude ~30 sec

Open claude.ai (or Claude Desktop). Start a new conversation.

Type this exactly, replacing the path with where you unzipped:

/install plugin from /Users/yourname/Documents/gst-invoice-generator-plugin/

Hit enter. Claude installs the plugin and confirms with a message like:

✓ Installed gst-invoice-generator v1.1.0
   Triggered by: "raise an invoice", "make a tax invoice", "show my dashboard"
Don't see the /install command? Make sure you're on Claude Pro / Team / Max plan — the free tier doesn't support custom plugins. Upgrade at claude.ai/upgrade.
4

Generate your first invoice ~30 sec

In the same conversation, just describe the sale in plain English:

Try one of these:

raise an invoice for Reliance Industries, ₹25,000, web design, Mumbai
create a GST invoice for Tata Consultancy, 50K rupees, software consulting, Bangalore
make a tax invoice for Acme Corp — ₹3 lakhs, app development, Maharashtra

Claude will:

  • Auto-detect CGST+SGST vs IGST based on state
  • Suggest the correct HSN/SAC code
  • Convert the amount to Indian-numbering words ("Twenty-Nine Thousand Five Hundred Rupees Only")
  • Generate a professional PDF invoice
  • Auto-update your dashboard.html + invoice_ledger.csv
5

Open your dashboard ~10 sec

Once you've generated 1+ invoices, type:

show my invoice dashboard

Claude opens dashboard.html in your browser — beautiful overview of:

  • 📊 Invoices issued this month
  • 💰 Total revenue + GST collected
  • 📅 GSTR-1 filing due date (auto-calculated)
  • 👥 Recent clients
  • 📋 Live GSTR-1 ledger preview

The dashboard refreshes automatically every time you generate a new invoice.

6

Export your GSTR-1 ledger end of month

When monthly filing is due (11th of next month), just say:

export my GSTR-1 ledger

Claude points you to invoice_ledger.csv in your plugin folder. Open it in Excel — every column required for GSTR-1 filing is there: invoice number, date, recipient GSTIN, place of supply, taxable value, CGST/SGST/IGST split, grand total.

Coming in v1.3 (this week): One-click export to the exact JSON format that gst.gov.in portal expects. Until then, the CSV gives you everything in the right columns — your CA can reformat in 5 min if needed.

That's it. You're done.

Generate as many invoices as you want — no monthly cap, no per-invoice charge.
