Problem

D2C brand fielded 300+ WhatsApp messages daily. Two reps couldn't keep up; response time crept past 6 hours and reviews started reflecting it.

Channels

  • WhatsApp Business

Sample turn

UserWhere is my order #2841?
AgentYour order ships today and arrives Friday — tracking: [link]. Anything else?

What I built

  • Shopify-connected agent for order status, tracking, returns
  • Recommendation engine using product catalog + customer history
  • Always-handoff for refunds over €100 or complaint tone detected
  • Per-rep dashboard showing handoffs with full conversation context

Limits

  • WhatsApp Business API only — does not work on personal numbers
  • Returns are initiated but final approval needs a human rep
