B2B Vegetable Ordering App

I run Kraple Fresh, a wholesale vegetable supplier, and I need a straightforward mobile solution that lets my B2B customers place orders quickly and track them with zero confusion. The app must run on both Android and iOS, present a clean, minimalistic interface, and allow users to locate produce simply by typing the vegetable name.

Core functionality I’m expecting:
• Secure mobile-number login and self-registration with profile editing
• Product catalogue showing name, price per kg / bunch, and an image for each item
• Easy cart and checkout so customers can create orders, view order history, and see real-time status updates (Pending, Processing, Delivered)
• Push notifications for order confirmation and every status change
• Delivery module where customers choose an address and preferred delivery date
• Web-based admin panel to add or remove products, adjust daily prices, manage customers, review all orders, and export order data to Excel

Looking ahead, I want the architecture to leave room for WhatsApp messaging, online payments, and multi-language support, so please choose a tech stack that can scale in that direction.

When you respond, please include:
• Your total development cost broken down by milestones
• Estimated timeline to reach a store-ready release
• The technologies / frameworks you propose (e.g., Flutter, React Native, Firebase, Laravel, etc.)
• Links or store listings for similar ordering apps you have already built

If you need any clarifications, feel free to ask—I’m ready to move quickly once I find the right partner.
