[OVERVIEW]

[THE CHALLENGE]

Small business owners juggle Excel, WhatsApp bills and a CA who sees the books once a quarter. Cash-flow surprises and late GST filings are normal.

[THE SOLUTION]

A clean multi-tenant SaaS that sends GST-ready invoices with UPI links and auto-reminders, scans any bill with AI and categorises it, reconciles bank transactions, and forecasts runway from real cash flow.
