The Opportunity

Problem

Hotels and restaurants in Senegal experience constant power outages that cause downtime in their cloud-based reservation and management software, resulting in lost revenue during peak tourist seasons.

Solution

PowerSyncReserve is a progressive web app (PWA) that runs fully offline on any device, allowing hotels and restaurants to manage reservations, check-ins, and tables during outages. It uses local storage to queue changes and automatically syncs with your existing cloud software (like ResNexus or HotelRunner) via API when internet/power restores. This ensures zero revenue loss even during peak tourist blackouts.

Target Audience

Differentiator
