E-com substitution & last-mile exceptions

Best for:
Customer Experience
Fulfillment
Last-Mile Logistics
Outcome
Higher order completion rates, fewer cancellations from out-of-stocks, improved NPS, reduced last-mile delivery failures.
Case type (unit of work)
Substitution/Exception Resolution Case = (1 case = 1 substitution approved or exception resolved via voice + order updated + evidence stored)
What DUVO delivers
Duvo pushes substitution options through digital channels first, then escalates to voice calls when customers don't respond - capturing approval, updating order systems, and saving sales that would otherwise cancel.
01
Receives substitution trigger from OMS/WMS (item unavailable, suggested alternatives, fulfillment deadline)
02
Pushes substitution options via app notification, SMS, and email with response deadline
03
Monitors for customer response; if no response within SLA, escalates to outbound voice call
04
Voice agent presents alternatives, negotiates customer preference, captures approval or refund request
05
Updates OMS with customer decision; triggers fulfillment or refund workflow
06
Handles last-mile exceptions (missed delivery, access issues) with same escalation logic
