Will the app support home delivery, store pickup, or both? Do you require user authentication and order tracking features? Are prescription uploads or medicine category restrictions required for certain products? Best Regards, Srashtasoft Team

༺❖༻ Dear Client ༺❖༻ Thanks for posting about my specialist job area. Your required skills perfectly match my experience and work style. I’ve built Android marketplace and inventory based applications where product listings payments and stock synchronization work in real time. For example I developed a retail app where every purchase instantly updated inventory across the backend and POS system ensuring accurate stock control. I can develop your medicine marketplace app with a clean user friendly interface supporting around 2000 SKUs with fast search smooth browsing and secure checkout using Bank Transfer and UPI. The system will be built with a strong backend that handles users transactions and inventory updates reliably. The POS integration will ensure that whenever a purchase is made the stock reflects immediately in the app and remains consistent across all systems. This will be designed with scalable APIs so future expansion is easy without breaking existing flows. I will start with system architecture and API design then build the Android frontend payment integration and inventory sync followed by testing for accuracy and stability. Given the opportunities to apply my passion and expertise to your project I am sure I will complete it perfectly on time and on budget. Let’s discuss your POS system so I can align the integration properly. Best regards, Glenn Bondoc
