Indian solar and real estate agencies struggle with manual lead generation – endless calls, spreadsheets, missed WhatsApp inquiries. Enter zero cost lead gen n8n India: self-hosted automation capturing Google Forms leads, storing in Supabase, and notifying via WhatsApp instantly. No Zapier fees (₹2000+/mo), full control, unlimited runs for solar real estate automation.
The Cost Problem: Why Cloud Automation Fails MSMEs
Zapier Starter: ₹2000/mo (750 tasks), Pro: ₹4000/mo. Solar agency with 50 leads/day = 1500 tasks/mo = extra tiers. n8n self-hosted: ₹0 forever after VPS (~₹500/mo).
- 80% agencies abandon paid tools within 6 months
- Manual processes miss 60% leads during off-hours

Step-by-Step Lead Workflow Setup
- 1.Create Google Form for solar/real estate inquiries
- 2.Self-host n8n, create webhook trigger
- 3.Connect Supabase/PostgreSQL for lead storage
- 4.Integrate WhatsApp Cloud API notification
- 5.Test: Submit form → instant team alert
