Dairy Farm Management Application Development

I want to convert my existing Excel sheet into a simple application for managing my dairy farm, cheese factory, and distribution workflow. This app should run on tablets, supporting role-based access and real-time data synchronization.
Scope of work

- Convert existing Excel sheet into a web app with role-based access.
- Develop separate screens for factory, distributor, and farm worker tablets.
- Implement data synchronization across all devices in real-time.
- Generate simple reports for milk production, cheese stock, sales, and feed inventory.
- Design a user-friendly interface with Arabic label support.
- Evaluate Web App vs. Mobile/Tablet App options (Flutter/React Native/AppSheet/PowerApps) and propose the best.
- Replicate existing Excel workflow in the app.
- Reporting and motoring is most important
