Android Construction ERP App

Budget: ₹12500 - ₹37500

I need a mobile app built natively for Android that functions as a full-scale construction and field-management ERP. The core idea is to give site supervisors, project managers, and office staff one place where they can track projects, crews, materials, and financials in real time from the jobsite.

Key screens include project dashboards, daily logs, timesheets, inventory levels, purchase orders, and simple cost-to-complete reporting. Data must sync reliably even when the device is offline, then push to the server once a connection returns. I already have rough workflow diagrams and can supply sample JSON for each module, so you’ll be able to jump straight into UI/UX and API integration.

Deliverables • Interactive Figma (or similar) prototype for sign-off • Android Studio source code with modular architecture (MVVM or clean architecture preferred) • REST/GraphQL integration layer and local persistence (Room or Realm) • Unit and instrumented tests plus a short user guide • One round of post-launch bug fixes

Acceptance criteria: the app installs on Android 10+, all listed modules load within three seconds on mid-range devices, and offline data sync resolves without conflict loss.

If you’ve shipped complex field apps before—especially in construction or logistics—let me know; that experience will be invaluable here.
