AI chatbot built for a roofing business to handle site visitors 24/7. Homeowner engages instantly, books an inspection straight into Calendly without leaving the chat, and gets an automatic email confirmation with the calendar link while the lead's details route to the owner in real time. No missed forms, no delayed callbacks, no lost leads to competitors who answer faster.

Cover image for Customer opens the chatbot on

Customer opens the chatbot on a solar website. 🌞 Books an appointment. Types in their details. Here's what fires automatically in seconds: ✅ Details captured & saved 📩 SMS → customer 💬 WhatsApp → customer 📧 Email → customer 💬 WhatsApp → owner 📧 Email → owner (full lead details) 📊 Google Sheet updated 🗂️ CRM updated No form. No hold music. No "someone will call you back." Just a chatbot handling the entire booking-to-notification chain while the owner does everything else. This is what lead capture should look like in 2026. Built this exact flow for a solar client. If your team's still manually logging appointments and chasing follow-ups DM me or comment "SOLAR."
