The Opportunity

Problem

Frequent power outages in Tunisian cities cripple cloud-based hospitality apps, forcing hotels to abandon digital tools for slow, error-prone manual processes.

Solution

BlackoutCheckin is a mobile-first PWA for guest arrivals, check-outs, and keycard management that stores all data locally during outages. It syncs guest profiles, payments, and IDs to the cloud instantly upon reconnection. Hotels avoid long lines and errors from manual logs.

Target Audience

Hotel operators and managers in Tunisian cities dependent on cloud hospitality software

Differentiator

Front-desk specific offline workflows with ID scanning simulation and folio printing—optimized for high-traffic outages in Tunis hotels.
