GST Invoice Generator — Raise GST-compliant invoices in 30 seconds

If you're an Indian freelancer or CA, you're nodding right now.

Every Indian SMB has the same four pains. We fixed all of them.

😩

"30 minutes per invoice."

Copy GSTIN. Look up state code. Calculate CGST and SGST manually. Hunt for HSN code. Format in Word. Convert to PDF. Send. Repeat 50 times a month.

✓ Our fix: Type 1 line in Claude. 30 seconds later, perfect PDF. CGST/SGST/IGST auto-detected from state codes.

💸

"Tally is ₹15,000 a year. And I needed an accountant just to install it."

Zoho Books wants ₹6,000/year. QuickBooks doesn't even support GST properly. CA charges ₹500 every time you "send wrong format". Recurring spend forever.

✓ Our fix: ₹9,999 once. Lifetime access. No accountant needed. Setup time: zero.

🚨

"Last quarter I missed GSTR-1 deadline because my invoice ledger was a mess."

Every invoice in a different folder. Excel sheets that don't match. CA chases you 5 days before deadline. Late fee + interest + stress.

✓ Our fix: Every invoice auto-appended to GSTR-1 ready CSV. Click "Export" → upload directly to GST portal. Deadline-proof.

🤯

"GST officer bounced my invoice because amount in words was wrong."

"Two lakh thirty three thousand fifty rupees only" — written incorrectly = invoice rejected = customer credibility damaged + payment delayed.

✓ Our fix: Indian numbering system built-in. Lakhs, crores — perfect every time. Even past one crore.

Everything you need. Nothing you don't.

Built specifically for Indian GST compliance. Not a generic tool with India bolted on.

How does this actually work?

It's a plugin (skill) for Claude — Anthropic's AI assistant. After you buy, you download a small ZIP, drop it into your Claude folder, and restart Claude. Then you can say things like "raise an invoice for Acme Corp, ₹50,000, web design, Bengaluru" — and Claude generates a perfect GST PDF instantly.

Do I need to be technical to use this?

No. If you can drag a folder, you can install it. We provide a 3-step PDF guide with screenshots. Most users are up and running in under 5 minutes. Worst case, email us — we'll set it up for you.

Is this really lifetime, or is there a hidden subscription?

Real lifetime. ₹9,999 once. Never again. We make money by acquiring customers cheaply at this price; we don't need to nickel-and-dime you forever. All future updates included free.

What about GSTR-1 filing? Do you file for me?

No — we generate a GSTR-1 ready CSV that you (or your CA) upload directly to the GST portal. Filing is not allowed by RBI for software vendors without a specific licence. But the prep work — which is 95% of the pain — is fully automated.

What if I don't like it?

30-day money-back guarantee. Email us, get a full refund, no questions asked. Razorpay processes refunds in 5-7 business days.

Does it support white-label / my own logo?

Yes. You configure your business GSTIN, address, logo, signature, and brand colors once. Every invoice uses your branding. Looks fully professional.

Can I use this for inter-state and intra-state invoices?

Yes. The plugin detects the recipient's state from their GSTIN and automatically applies CGST+SGST (intra-state) or IGST (inter-state). Zero math errors.

What if Claude isn't available in India?

Claude (claude.ai) is fully available in India. The plugin also works with Claude Code (CLI), Cowork, and any future Claude interface. The skill is just files on your computer.

Is my data safe? Where is it stored?

Your data stays on your computer. The plugin runs locally — invoices, ledger, customer data — never leaves your device. We don't have a server that stores your invoices. See our Privacy Policy.

Will this work for my industry / business type?

Works for: freelancers (designers, devs, writers, photographers), service agencies, consultants, CAs, e-commerce sellers, manufacturers, IT/SaaS companies — anyone who raises GST invoices. Not built for: retail POS / restaurants (different tooling needed).
