How to Create a GST Invoice Online in Under 2 Minutes

Step 1: Set up your business

Enter your legal name, address, GSTIN, PAN, bank details and UPI ID once. Upload a logo and signature so every invoice looks professional.

Step 2: Add a client

Name, GSTIN and state. The state code determines CGST/SGST or IGST automatically.

Step 3: Add items

Type the product name — saved items auto-fill HSN, rate and GST%. Add quantity and discount; totals compute live.

Step 4: Pick a template and save

Choose from 30 templates, preview and save. The invoice number is assigned sequentially.

Step 5: Share and get paid

Tap WhatsApp to send the PDF, or Email, or copy the public link. The invoice carries a UPI QR so customers pay instantly.
