Omnichannel AI Sales Agent for Automotive Lead Generation

Omnichannel AI Sales Agent for Automotive Lead Generation
1. Overview
Developed an omnichannel AI sales agent for a lead generation agency specializing in automotive services (e.g., car repair, painting). The AI agent automates lead qualification, answers FAQs, updates CRMs, and books appointments across Facebook Messenger, Instagram DMs, WhatsApp, and website forms. By reducing manual follow-up time from 24+ hours to instant responses, the system increased booked meetings by 50% and freed 80% of the agency’s sales team to focus on high-value tasks.
2. Tech Stack
Core Platform: n8n (end-to-end workflow automation, logic, and API orchestration)
AI/ML Components:
GPT-4 (conversation handling, appointment booking logic)
RAG (Retrieval-Augmented Generation for FAQ responses using document embeddings)
OpenAI Whisper (voice message transcription)
Integrations:
WhatsApp Business API (managed via n8n for messaging)
Facebook/Instagram APIs (handling DMs and lead routing through n8n)
Google Calendar API (appointment scheduling via n8n workflows)
CRM: HubSpot/Pipedrive (connected via n8n for real-time lead updates)
Database: Supabase (stores chat history, lead data, and RAG vector embeddings)
Hosting: n8n Cloud (workflow execution, trigger management, and error handling)
3. General Flow
Lead Input:
Leads submit inquiries via website forms, Instagram/Facebook DMs, or WhatsApp.
Voice messages are transcribed to text using Whisper.
AI Qualification:
The AI agent greets leads, asks qualifying questions (e.g., car model, service needed).
Uses RAG to pull FAQs from a knowledge base (e.g., service benefits, pricing).
CRM Update:
Validated lead details (name, contact, car info) are auto-added to the CRM.
Appointment Booking:
Integrates with Google Calendar to check availability and book slots.
Sends confirmation via the original channel (WhatsApp, DM, etc.).
Rescheduling:
Allows leads to modify/cancel appointments via chat.
4. Input & Output
Input:
Text/voice messages from leads (e.g., “I need paint protection for my Tesla Model 3”).
Calendar availability from the agency’s clients (e.g., repair shops).
Output:
Qualified leads added to CRM with tags (e.g., “Interested in window tinting”).
Booked appointments synced to Google Calendar.
Instant responses to FAQs (e.g., “Window tinting blocks 99% of UV rays”).
5. Key Features
Omnichannel Support: Unified AI agent across WhatsApp, Instagram, Facebook, and web forms.
RAG-Powered Answers: Instant, accurate responses to FAQs using a automotive service knowledge base.
Dynamic CRM Sync: Auto-updates lead status, tags, and notes in real time.
Calendar Integration: Books, reschedules, or cancels appointments without human intervention.
Error Mitigation: Fallback to human agents if AI confidence is low (e.g., complex queries).
Scalability: Template-based setup for quick deployment across the agency’s 10+ clients.
