Good to see this project, I will build the Base 44 app for iOS and Android — covering vendor collaboration, in-app payments, and real-time messaging — along with the supporting website. I will deliver both platforms from a single codebase using Flutter or React Native to keep development fast and maintenance simple. For the payment flow, I will integrate Stripe Connect so invited vendors pay directly through the app while you control payout timing and fee splits. This avoids building custom payment logic and handles compliance out of the box — critical when money moves between multiple parties. Questions: 1) Do you have the Base 44 source code ready, or will I be rebuilding the logic from their platform's design? 2) What payment model applies to vendors — one-time fee, subscription, or per-transaction? Looking forward to your response. Best regards, Kamran

Hi, there The real challenge is not the conversion itself but making collaboration feel instant and dependable for real estate professionals and invited vendors, because weak messaging or payment friction kills adoption fast. This should be handled as a controlled cross-platform build with shared business logic, stable real-time messaging, and a payment flow that is simple for vendors and easy to manage operationally. Clear separation between agent and vendor actions matters as much as the codebase. The key here is reducing coordination friction, since the product wins only if users can message, respond, and pay without leaving the workflow. That drives usage, retention, and trust. The first step is mapping the current base 44 logic into a production-ready app structure, then rolling out core collaboration flows before publication. This needs to move quickly, but in a structured way from day one..

Hi there, I have read your project requirement. You need to convert your Base44 app into iOS and Android apps along with a supporting website, including real-time messaging, vendor collaboration, and payment integration. We will build a cross-platform solution (Flutter/React Native) with a scalable backend, enabling real-time messaging (Firebase/WebSockets), secure vendor payments (Stripe/Razorpay), and a clean, user-friendly interface. The website will mirror core functionality for seamless access, and the system will be optimized for performance and future scalability. Questions: ========== Is the existing Base44 app code available for reuse or are we rebuilding from scratch? Which payment gateway do you prefer for vendor payments? Do you need role-based access (agents, vendors, admins)? Any timeline constraints for initial release? Best Regards, Srashtasoft Team
