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

PowerQueue captures orders via SMS/WhatsApp during blackouts, queues them offline, and auto-processes inventory/orders on reconnection. Integrates with stores to confirm stock without losing sales. Simple phone-based fallback for unreliable power/internet.

Target Audience

Ghanaian e-tailers managing online stores and inventory systems

Differentiator

SMS-first gateway optimized for Ghana's mobile penetration, no app install needed for customers.
