WhatsApp Sales Bot

Challenge

A Mexican small business was spending over 20 hours per week on manual customer support — answering the same product questions, qualifying leads, and routing inquiries. Response times during off-hours meant lost sales, and the team couldn't scale support without hiring additional staff.

Solution

Built an AI-powered WhatsApp sales assistant using retrieval-augmented generation (RAG). The bot ingests the client's product catalog, pricing, and FAQ documentation into a vector store, then uses an LLM to generate accurate, contextual responses in natural conversational Spanish.

Key capabilities:

• Product knowledge — Answers detailed questions about products, pricing, and availability by retrieving from the client's own documentation
• Lead qualification — Identifies purchase intent and routes high-value leads to the human sales team
• Handoff protocol — Seamlessly transfers to a human agent when the conversation requires it
• Bilingual support — Handles conversations in both Spanish and English

Impact

• 90% reduction in response time — From hours to seconds, even outside business hours
• 24/7 availability — Customers get instant responses at any time
• 100+ concurrent conversations — Scales without additional headcount
• Human team freed up — Sales staff now focuses on closing deals instead of answering repetitive questions
