This case breaks down how we designed and implemented a cross-platform restaurant management system that works reliably across multiple branches — even with inconsistent network conditions and mixed hardware environments.
Core requirements
- Real-time sales and inventory sync
- Offline-first operation for unstable WiFi
- Role-based access control
- Multi-store data aggregation
- Cross-platform UI (desktop + tablet)
- Fast response time under peak load
System architecture
We used a modular, API-driven design:
[Frontends]
- Tablet Dashboard (Vue)
- Desktop Admin Panel (Web)
[APIs]
- RESTful service layer
- WebSocket for real-time sync
[Core Services]
- Stock management
- Sales records
- Employee roles & permissions
- Multi-store aggregation
[Data Layer]
- Cloud DB (Primary)
- Local SQLite fallback (Offline mode)
The offline-first approach ensures all store operations keep running even when the network drops.
Once reconnected, local records auto-sync to the cloud.
Device compatibility
Branch hardware varied widely:
old Windows PCs, Android tablets, and low-spec terminals.
To handle this:
- The UI was optimized for low-memory devices
- API responses were lightweight
- Sync operations were incremental, not full-dataset
Performance results
After deployment, the system improved:
- Stock update accuracy
- Data sync stability
- Operational efficiency during peak hours
- Manager visibility across all stores
Reusable components
This architecture is well-suited for:
- Multi-store retail management
- POS extensions
- Kitchen automation dashboards
- IoT-connected restaurant systems (smart freezers, energy sensors, etc.)
