Saj House operates seven locations across the Kurdistan Region and was losing repeat business to chains with stronger digital ordering. We scoped a 14-week build that prioritised the customer experience first and operational integration second. The app is native React Native with offline-first ordering and a deliberately simple loyalty model: scan once per visit, ten visits earns a free meal, no apps-within-apps. The backend syncs menus from the existing POS overnight and pushes orders back through a webhook contract we documented for the POS vendor. The most surprising win was operational: kitchen staff use the same admin app to flag 86'd items in real time, which cut customer-facing menu errors to near zero.

Challenge

A growing regional restaurant chain wanted loyalty, in-store ordering, and a single payment flow — without forcing a complete POS replacement at each location.

Solution

A React Native app talks to a NestJS backend that integrates with the existing POS via menu sync and order webhooks. QR-based loyalty works whether the customer scans at the counter or pays online.

Results

Repeat-order rate climbed 27% within three months of launch; average order value is up 14% across self-ordering venues.
