Multilingual WhatsApp Sales Bot for an International Freight Forwarder

The challenge

The business needed a system that removed repeated manual work while still respecting the real operating process. Instead of forcing a generic template, the automation was designed around the actual flow of leads, conversations, records, approvals, service steps, and follow-up actions.

The solution architecture

The system combines workflow automation, persistent data storage, API integrations, and business rules. n8n handles orchestration where external systems are involved, while Zoho, PostgreSQL, or AI agents handle state, records, and decision-support depending on the project.

Key technical decisions

• Use structured data and persistent storage so automation can resume, audit, and report reliably.
• Use AI only where it has a clear business job: qualification, reply generation, storyboarding, or prompt correction.
• Keep humans in the loop at handoff points such as quote requests, approvals, invoicing, or final review.

Results and impact

• Sequential lead qualification for route, cargo, weight, and mode
• Last 100 messages retrieved for context on every inbound message
• 24-hour and 72-hour automated follow-ups
