A solo freelancer with 2L+/month turnover needs a simple, fast, affordable mobile-first GST invoicing tool but finds existing options too complex, expensive, clunky, or limited.

Existing tools are either too complex and expensive (Zoho), have outdated clunky UIs (Billbook, myBillBook), lack a mobile app (Refrens), or cap free usage too low (InvoiceBhai). No tool combines simple setup, low cost, mobile-first design, and sufficient free tier for a solo freelancer.
