WhatsApp CRM: Six Business Numbers, One Lead Pipeline

An events company took enquiries on six WhatsApp numbers. Follow-ups lived in people's heads, enquiries went unanswered after hours, and there was no shared view of which dates were already booked.

One pipeline for six WhatsApp Business numbers, built on a fork of the open-source OpenBSP platform running on Supabase.

A lead bot that asks the qualifying questions with WhatsApp list and button messages, then hands each lead to a human manager.

A shared inbox where managers pick up the conversation.

A dashboard with today's leads, follow-ups due, and a calendar of the four event slots per day with live booking status.

Seven n8n workflows: nudge silent leads, close stale ones, follow-up reminders, an evening brief of tomorrow's events for each manager, alerts for unanswered qualified leads, bot health checks, and a 15-day report.

Supabase Postgres with row-level security and 18 edge functions; n8n, the dashboard and the inbox run on a VPS behind Traefik with TLS. An automated harness drives real conversations through the bot, and all seven scenarios pass.
