Multi-tenant CRM built for solar (photovoltaic) sales teams. Covers the full sales cycle: lead pipeline (Kanban), payments and installment tracking, WhatsApp Business integration (webhooks + automations), internal messaging, push notifications (FCM), calendar and appointment reminders, and automated document generation (contracts, invoices, technical sheets, questionnaires). Built on Supabase (Postgres + Edge Functions + tenant-scoped RLS), a React/TypeScript front end, and Capacitor for Android/iOS builds. Goal: industrialize solar prospecting and shorten deal cycle time.
