Snowfall Delivery Delay Auto-Notification

3.85

Derivation Chain

Step 1 Frequent nationwide heavy snow and cold waves

→

Step 2 E-commerce sellers' delivery delay CS surge

→

Step 3 Weather-linked automatic delivery notice and CS notification service

Problem

When weather events like 40cm heavy snowfall in Gangwon mountain areas occur, Smart Store and Coupang Marketplace sellers see delivery delay inquiries surge 3-5 times above normal, but they must manually send notification messages for each order. For sellers with 500+ monthly orders, each snowfall event adds 8-15 hours of CS response time, and failure to respond leads to lower purchase ratings and penalties.

Solution

By integrating the Korea Meteorological Administration API and courier delivery status APIs, it automatically identifies affected delivery orders when weather alerts are issued and sends preemptive delay notification messages (Kakao AlimTalk/Naver TalkTalk) to buyers. The seller dashboard shows affected order status and estimated delay days in real time.

Target: Individual/small-scale sellers on Naver Smart Store and Coupang Marketplace with 300+ monthly orders

Revenue Model: SaaS monthly subscription: 29,000 KRW (approx. $22) per store, 15,000 KRW (approx. $11) per additional store, plus 15 KRW (approx. $0.01) per AlimTalk sent

Ecosystem Role: Supplier
