Car Rental RAG Chatbot — 24/7 customer support with zero staff
The Problem
A car rental agency received 200+ daily WhatsApp inquiries about pricing, availability, and policies. Two full-time staff couldn't keep up, leading to lost bookings and slow responses.
The Solution
Deployed a RAG-powered chatbot on WhatsApp using n8n. The bot ingests the company's fleet data, pricing rules, and policies into a vector store, then answers customer questions instantly and can initiate bookings.
