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.

What's Included

12 Production Workflows

#	Workflow	Function
01	Order Intake	Webhook receives new orders, validates, routes by payment type
02	COD Confirmation Call	AI voice call to confirm cash-on-delivery orders
03	Prepaid Confirmation	SMS confirmation + optional high-value voice call
04	Call Result Handler	Processes Vapi callbacks, routes by outcome
05	Retry Engine	Auto-retries unanswered calls on schedule
06	WhatsApp/SMS Fallback	Multi-channel fallback for unreachable customers
07	Returns & FAQ Handler	Intent-based routing for support queries
08	Order Status Updater	Syncs status back to Shopify/WooCommerce
09	CRM & Sheet Logger	Central event logging + HubSpot sync
10	Outbound Campaign	Proactive engagement for unconfirmed orders
