Android Business Audit & Tracking App

I need an Android application that pulls together business audits, complete client history, field-staff tracking and billing in one place. Audit module - Customizable audit forms I can edit from an admin panel - In-app photo uploads attached to each checklist item - Automatic PDF report generation right after submission Workforce module - Real-time location tracking while a worker is on duty - Daily activity log that syncs even when the phone is offline - Task assignment with live status updates so I can monitor progress Billing & client records - Generate professional bills directly from the completed audit - Store every visit, photo and note under the client’s profile with quick search The app should sync smoothly online/offline, send push notifications and have a clean, modern UI. I am open to Kotlin, React Native or any reliable Android stack as long as the final APK is Play-Store ready. Deliverables 1. Full Android source code 2. Compiled APK for testing and final release 3. Simple admin/back-end (web panel or Firebase) to manage forms, users and data 4. Brief documentation and a hand-over walk-through If this fits your expertise, contact me directly at [Removed by Freelancer.com Admin] so we can discuss timelines and milestones.
