Offline Android Billing Solution

@mrresearcher99

This project fits perfectly with my background. I have 5+ years of experience building Android applications using Java and Kotlin, including offline-first apps, Bluetooth printer integration, PDF generation, and tablet-optimised UIs. I can deliver a fully offline Android billing app designed for stylus input. Handwritten item name, quantity, and rate will be captured using on-device handwriting recognition and automatically placed into a table, with discount support and accurate total calculation. No internet connection will be required at any stage. The app will support 58mm and 80mm Bluetooth thermal printers with a clean receipt layout showing only the item list and grand total, exactly as specified. Each bill will also be saved locally as a PDF and can be shared instantly via WhatsApp. All bills will be stored in an on-device history, searchable and viewable inside the app, with options to export reports as CSV or PDF. Data will be stored using a local database to ensure reliability in airplane mode. I will deliver a test-ready APK and well-structured source code. The project will be considered complete only after the app runs smoothly on Android tablets, supports stylus input, prints correctly, saves history, and exports reports entirely offline. Best, Bhargav

Hello, We can build a lightweight offline-first Android billing app that lets you create bills using stylus handwriting, convert entries into structured bill items, and calculate totals with optional rupee-value discounts — all without any internet connection. The app will support handwriting-to-text input for item name, quantity, and rate, store every bill locally with full history, and generate a clean PDF that can be shared instantly via WhatsApp. All data will remain on-device, with smooth performance in airplane mode and simple export options (CSV/PDF) for later reporting. I’ll deliver the Android APK, clean source code, and ensure compatibility on Android tablets. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress. Lets connect over chat and discuss.

I can build a lightweight, fully offline Android billing app designed specifically for stylus-based handwritten entry and fast thermal printing, with zero dependency on internet connectivity. The app will allow handwritten input for item name, quantity, and rate, converted to text using on-device handwriting recognition so it works even in airplane mode. Each recognised line will populate a simple bill table, with support for a rupee-value discount before calculating the final total. At one tap, the bill will print to Bluetooth thermal printers (58 mm and 80 mm) using the exact clean layout you described—item list + grand total only, no headers, GST, or branding. The same bill will be saved locally as a PDF and can be shared instantly via WhatsApp. Every bill will be stored in an on-device history, viewable inside the app and exportable later as CSV or PDF for reporting. All data storage, printing, PDF generation, and sharing will remain 100% offline. You’ll receive: • Android APK + clean, readable source code • Offline handwriting-to-text for item, qty, rate • Bluetooth thermal printer support (58 mm / 80 mm) • One-tap PDF generation & WhatsApp sharing • Local bill history with export options The project is complete once the APK runs on any Android tablet, supports stylus input, prints, saves, and exports bills entirely offline. Ready to start immediately.
