I want a clean, lightweight Android application that my field sales team can open, log in with their company email and password, and capture secondary-sales orders on the spot. Two roles matter to me: • Salesman – enters demand, adjusts MRP-based discounts, and submits the order. • Manager – reviews or edits what the salesman submitted and can pull quick reports. The core flow is simple: after login the salesman selects the customer, adds products with quantities, sees the auto-calculated total, applies any discount by percentage or value, and taps “Generate Order”. The app must immediately create a branded PDF containing all line items, MRP, discounts, net values, date/time, and the salesman’s details. That PDF should save locally and be shareable through WhatsApp or email without needing extra steps. Functional expectations • Smooth email/password authentication. • Offline data capture with background sync when the device is back online. • A manager screen that lists each order, shows basic analytics by date or salesman, and lets me export data (CSV/XLS is fine). • A reusable, professional PDF template coded inside the app so formatting stays consistent across devices. Deliverables – Full Android Studio source code and a signed release APK. – The PDF layout file(s). – Brief setup notes so I can change product lists, MRP values, and discount rules later. – One short hand-off call or video to walk through build and deploy steps. If you have already built something similar with Kotlin, Java, or Flutter and can adapt it quickly, let me know; faster turnaround is welcome as long as quality and stability are there.
