eComm AI Voice Agent 📞

A production-ready, 12-workflow AI voice agent system for eCommerce businesses. Handles order confirmation calls, customer support, returns, retries, and outbound campaigns — fully automated.

Problem

eCommerce businesses (especially COD-heavy markets) lose 20-40% of orders to fake orders, no-shows, and unconfirmed deliveries. Manual confirmation calls are expensive and don't scale.

This system automates the entire confirmation and support lifecycle using AI voice calls.
