Multilingual WhatsApp Sales Bot for an International Freight Forwarder

The challenge

A freight forwarder receives WhatsApp enquiries in multiple languages at all hours, and a sales team cannot reply instantly or consistently qualify each one for route, cargo, weight, and mode.

Conversations also span many messages over days, so without stored context the team loses the thread of what a lead has already shared.

The solution

A WhatsApp AI sales assistant built on n8n and Gemini qualifies freight enquiries in English, Hindi, and Telugu, then alerts the sales team the moment a quote is requested.

Every conversation is persisted in PostgreSQL and delivered through the Exotel WhatsApp API, so the bot always answers with full context.

Implementation

• Implemented sequential lead qualification that collects route, cargo, weight, and mode before handing off.
• Retrieved the last 100 messages for context on every inbound message so replies stay coherent across long threads.
• Added 24-hour and 72-hour automated follow-ups to re-engage leads that go quiet.

Results

• Incoming freight enquiries are qualified automatically in three languages, day or night.
• The sales team is alerted exactly when a quote is requested instead of monitoring chats manually.
• The assistant is live and handling real leads.

Impact

• Sequential lead qualification for route, cargo, weight, and mode
• Last 100 messages retrieved for context on every inbound message
