How We Built an AI Support Agent for a D2C Brand
A WhatsApp-based AI support agent that handles 70% of customer queries automatically. Here is how we built it, what worked, and what we learned.

The Challenge

Our client, a fast-growing D2C apparel brand, was drowning in customer support tickets. 70% of the queries were routine: "Where is my order?", "Do you have this in size M?", and "What is your return policy?"

Their support team was spending hours answering these basic questions, leading to slow response times for complex issues that actually needed human intervention.

The Solution

We built a custom AI agent powered by GPT-4 and integrated it directly into their WhatsApp Business account. The agent was trained on their product catalog, return policies, and connected to their Shopify backend via API to check real-time order status.

The Results

The impact was immediate:

  • 72% of all inbound queries are now resolved by the AI without human intervention.
  • Average response time dropped from 4 hours to 3 seconds.
  • Customer satisfaction scores actually increased, as customers got instant answers.
  • The support team was freed up to handle high-value tasks like VIP customer retention and complex dispute resolution.

The key to success wasn't just the AI model — it was the tight integration with their existing data sources (Shopify, logistics partners) that allowed the AI to take actual actions, rather than just give generic answers.
