The Opportunity

Problem

Frequent electricity blackouts in Ghana disrupt online store operations and inventory management systems for e-tailers, causing downtime and lost sales.

Solution

DumsorSync is a PWA that lets e-tailers manage inventory and orders fully offline on any device. Changes auto-sync to the cloud and connected platforms like Shopify when power and internet return. No data loss, no downtime—seamlessly bridging outages.

Target Audience

Ghanaian e-tailers managing online stores and inventory systems

Differentiator

Tailored for Ghana's dumsor patterns with predictive sync queues based on local outage schedules.
