The Challenge

A professional services firm was losing bookings to missed calls and slow email responses, with scheduling handled manually by their receptionist.

The Approach

Designed a conversational flow covering the full booking lifecycle: availability check, confirmation, reminder, rescheduling, and post-appointment follow-up. Prioritized natural language over rigid menus.

The Solution

Built a WhatsApp Cloud API bot with NLP-based intent detection, real-time Google Calendar sync, automated reminders at 24h and 1h before appointments, and a Supabase backend for booking history and analytics.

Architecture

How a booking conversation travels from the customer to a confirmed appointment and back.

Human handoff is an explicit escape path: a conversation can be passed to a person at any point rather than being forced to stay automated.
