Problem: Plumbers lose jobs every day simply because they can't pick up the phone. They're under a sink, on a roof, or driving — and the caller dials the next number on Google. Every missed call is lost revenue.
  
 Solution: Sarah, an AI voice agent for "Plombier Express Lyon" that answers every missed call in seconds. She collects the customer's name, phone, address, and problem, detects urgency, checks real availability, and books the appointment — 24/7, even at midnight.
  Everything appears live on a bilingual (FR/EN) dashboard: leads with urgency badges, an appointments calendar, call history, and monthly revenue stats. The plumber creates a quote in one click (client data pre-filled) and sends it as PDF. The client receives it on Telegram/WhatsApp and accepts with a simple message — "ACCEPT DEV-2026-0003" — and the quote status updates automatically while the plumber gets notified.
 Tech: FastAPI + Postgres backend with a swappable voice adapter (Retell AI today, Pipecat-ready) and swappable notifications (Telegram, Meta WhatsApp Cloud API, Twilio WhatsApp + SMS). Angular + Material dashboard with live polling. Retell custom functions (create_lead, check_availability, book_appointment) connected via webhooks. Why it matters: One recovered job pays for the whole system. Built for artisans first — no app to install, no login for the customer, just a phone call and a message.
