Generating an invoice shouldn't cost money. Yet many businesses still pay for invoicing tools when free options now offer everything needed for GST compliance, professional formatting, and instant delivery.
This guide covers the best free invoice generators available to Indian small businesses in 2026 — and shows you exactly why Khata Billing stands above the rest.
✅ Key Takeaways
- Free forever — 10 invoices a day, no credit card
- Auto GST calculation — CGST/SGST/IGST
- Professional PDF invoice with your logo
- Sequential invoice numbering — automatic
- Customer database — saved for reuse

What Separates a Good Free Invoice Generator from a Bad One
Most free invoice tools online have a fatal catch: they either limit you to 5 invoices per month, add ugly watermarks to your PDF, don't support GST fields, or lock PDF download behind a paid plan.
A genuinely good free invoice generator for India must offer:
- Enough free invoices to run a real business day
- Full GST compliance (GSTIN, HSN/SAC, CGST/SGST/IGST)
- Professional PDF with your branding
- Customer database so you don't re-enter details
- Sequential invoice numbering (GST requirement)
Khata Billing meets every one of these on its free plan — 10 invoices a day, 100 per 30 days, at zero cost. Premium (₹1,499/year, or ₹999/year with code SAVE500) removes the limits and adds watermark-free premium themes.
