Offline-first inventory sync that keeps Ghanaian e-tailers running through blackouts.
Frequent electricity blackouts in Ghana disrupt online store operations and inventory management systems for e-tailers, causing downtime and lost sales.
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.
