SYSTEM ARCHITECTURE
Production WhatsApp system that handles e-commerce sales, order updates, and education program enrollment with human handoff.
The team was running two business lines through one overworked WhatsApp inbox. E-commerce buyers were asking about order status. Education prospects were asking about enrollment.
The team was answering the same 12 questions all day, copying order details from Shopify, and missing high-intent buyers because they were buried in low-intent messages.
They needed automation that handled the repetitive 80% and routed the rest to humans without losing context.
