I’m ready to turn a solid concept into a polished Android application focused squarely on business and productivity for my customers. The end goal is a Play-Store–ready build that lets users handle three core jobs in one place: • Task management – create, assign, track, and get notified in real time • Invoicing & payments – generate invoices, accept card / wallet payments securely, and surface simple analytics • Lightweight CRM – store customer profiles, log interactions, and view a history that ties back to tasks and invoices A clean, modern UI is key because my audience is external customers, not internal staff. They need to open the app and immediately understand what to do next without training. Here’s how I picture the flow: 1. A customer signs in (Google/Facebook/email) and lands on a dashboard that summarizes open tasks, outstanding invoices, and recent contacts. 2. From there they can dive deeper—update task status, pay an invoice through Stripe or Razorpay, or add notes to a contact, all while receiving push notifications powered by Firebase Cloud Messaging. 3. Admin tools (also inside the app) let me export reports in CSV or PDF and tweak basic settings without touching code. Tech-wise I’m comfortable if you lean on Android Studio with Kotlin or Java, Material 3 components, Room or Realm for offline storage, and a secure back-end of your choice (Firebase, Supabase, or a lightweight REST API). I need source code in a private Git repo, a signed release APK/AAB, and a brief hand-off video or document so I can publish future updates myself. Acceptance criteria • Tasks, invoices, and CRM modules function end-to-end with dummy data during testing • Payment flow completes in sandbox and returns success/failure messages visibly to the user • No crashes on Android 8-14; all major screens pass Google Play pre-launch report • Code compiles without errors in latest stable Android Studio If you’ve already shipped productivity apps, especially those integrating payments, let’s talk timelines and any questions you have about features or edge cases—I’m keen to move quickly.
