Book, pay, and get supportall inside WhatsApp, with zero manual scheduling work for the studio.
ZenVida is a WhatsApp-based customer automation platform built for a wellness studio in Madrid that needed to move appointment booking, payments, and customer support off manual phone/DM handling. The platform automates the complete customer journey through WhatsAppappointment booking, payment collection, AI-powered conversations, reminders, and follow-upsso clients can book, pay, and get support entirely inside a single chat thread.
Under the hood, a NestJS and TypeORM backend on Supabase (PostgreSQL) drives the booking and payment logic, while the WhatsApp Cloud API handles the conversational layer. The system reduces manual operations by replacing calls, DMs, and spreadsheets with automated customer support, booking management, and payment workflowsgiving the studio a single automated front door for client interactions.

Payment collection and booking confirmation depended on staff manually processing each request, creating friction and admin overhead as client volume grew.
Client support, scheduling, and payment tracking were scattered across calls, DMs, and spreadsheets instead of living in one system.
