We built GST Invoice Pro because we were tired of it too. GSTIN validation, CGST/SGST/IGST auto-split, AI HSN codes, and PDF invoices — free. No subscriptions to start.
Built specifically for India's GST regime — simple enough for any business owner to use from day one.
Type your 15-digit GSTIN and we instantly detect your state, validate the format, and flag errors before your client does.
Describe your product in plain English. Claude AI looks up the right HSN or SAC code and GST rate — the part everyone always Googles.
A clean, professional A4 invoice your clients will actually respect. Download, WhatsApp, email — done.
Our family business was paying ₹2,000 every month just to get GST invoices made. We spent a few weekends building this. Now you don't have to pay that.
No hand-picked success stories. Just feedback from people who were tired of paying too much for invoices.
"My CA was charging ₹1,500 every month. I'm a kirana shop — that's real money for me. My son set this up in 20 minutes. Now I send GST invoices myself and they look more professional than what my CA used to send."
"I do brand identity and packaging design for small businesses. Sending a proper GST invoice used to take me 30 minutes in Excel. Now it's 5 minutes. My clients comment on how clean and professional it looks — one even asked what software I use."
"We supply embroidery thread to garment units — 15 to 20 invoices a month across Gujarat and Maharashtra. The IGST vs CGST+SGST auto-calculation is the thing I didn't know I needed. Used to call my accountant every time. Not anymore."

Nope. Works in Chrome, Safari, Firefox — on your phone, tablet, or laptop.
Yes — completely. Your GSTIN is stored in your browser for convenience and never shared with third parties. Your invoices are securely backed up to our database (Supabase, hosted on AWS) using your account credentials. We cannot read or sell your business data.
Yes, it's fully mobile-responsive. The invoice form works on Android and iPhone. The PDF download works on mobile too — it'll save to your phone like any other file. Many of our users are on mobile the whole time.
You'll see a prompt to upgrade when you try to download your 6th invoice. The counter resets on the 1st of every month — so if you only need a few invoices, the free plan may be all you ever need. Upgrading to Pro gives you unlimited invoices for ₹99 in your first month.
No. The app handles CGST, SGST, and IGST automatically — just enter your GSTIN and the customer's Place of Supply, and the right tax splits. HSN codes? The AI suggests them from your product description. You'll still want a CA for your annual filing and returns, but for generating day-to-day invoices, you're fully covered here.
