The Problem

ModernRetail Co. was drowning in repetitive customer support tickets — order tracking, return requests, and product questions made up 80% of their volume. Their 4-person support team was spending most of their day on copy-paste responses, leaving complex issues unresolved for days.

The Approach

  1. 1

    Conducted a 2-day audit of their Zendesk history to identify the top 20 most common ticket types

  2. 2

    Built a RAG pipeline that ingests their product catalog, return policies, and shipping data in real-time from Shopify

  3. 3

    Developed a GPT-4 powered chatbot with custom system prompts tuned to their brand voice

  4. 4

    Integrated with Shopify APIs for live order tracking and return initiation

  5. 5

    Added a smart escalation system — the bot detects frustration and routes to a human agent automatically
