TheraNest, SimplePractice, CentralReach, and TherapyNotes are excellent platforms — but built for American healthcare. They use USD pricing, US insurance billing workflows, and host data outside India. TheraFlow is purpose-built for Indian therapy centres: INR pricing from ₹2,999/month, Hindi + English support, Indian school holiday calendars, DPDPA-compliant Indian servers, WhatsApp integration, and INR invoicing reconciled against session packages and issued through your own Zoho Books or Zoho Invoice account, so GST stays where your accountant already files it.
