The operating status of hundreds of stores,into a single calendar.

HallGrid is a management platform that lets you overview, register and filter the open/closed status of multiple stores on a single screen. It consolidates data scattered across Excel and individual stores into one real-time synced calendar.

This is the launch story of a new platform — built in-house from scratch in six months as a React admin screen — to solve the challenges of scattered data and manual entry.

CLIENT
About the client

“HallGrid”, aiming to streamline multi-store operations.

HallGrid operates the business data of several hundred amusement facilities nationwide. Accurately tracking each store's operating days, closures and key information — and sharing it quickly with stakeholders — was central to its operations.

Previously each store was managed in its own Excel file, making it hard to see the big picture or share updates instantly. An admin screen that consolidated multi-store data into one platform was needed.

Architecture built together

Built in-house from scratch — three views on one screen.
