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:
- Unlimited invoice creation
- Full GST compliance (GSTIN, HSN/SAC, CGST/SGST/IGST)
- Professional PDF with your branding — no watermarks
- Customer database so you don't re-enter details
- Sequential invoice numbering (GST requirement)
Khata Billing meets every one of these — at zero cost.
