Customer Service Mobile App Development

I need a cross-platform mobile application, released on both iOS and Android, whose sole focus is to streamline customer service for a network of online stores. Shoppers must be able to reach support quickly—think real-time chat, ticket creation, order-status look-ups, and a space for FAQs or self-help articles—so the interface has to be intuitive and fast. What I expect from you is a detailed project proposal that explains: • the technology stack you recommend (React Native, Flutter, Kotlin/Swift native, or any other approach and why); • high-level architecture, including how you will handle secure user authentication and data storage; • a milestone-based schedule from design through App Store / Play Store submission; • any third-party services or APIs you plan to integrate (push notifications, analytics, live-chat back end, etc.); • post-launch support or handover process. Deliverables • Production-ready iOS & Android apps that meet current store guidelines • Source code, build scripts, and concise developer documentation • Basic design files (Figma/Adobe XD/Sketch) for all screens • A brief test plan with results demonstrating core customer-service flows work end-to-end I am happy to clarify edge cases once I review your proposal; for now, please send that thorough plan so I can see how you will turn this concept into a smooth, reliable tool for our customers.
