iOS & Android Multi-Vendor Market App Development
Budget: $250 – $750 USD
Mobile App Development (iOS & Android) – CS-Cart Multi-Vendor Integration
We are building a vertical marketplace powered by CS-Cart Multi-Vendor and are looking for an experienced mobile developer or small team to develop a buyer-focused mobile application for both iOS and Android.
The app will function as a direct extension of our existing web marketplace. The backend (CS-Cart) will remain the single source of truth — we are not rebuilding backend logic. The mobile app must consume existing REST APIs and extend them only where strictly necessary to support mobile flows.
We are prioritizing a clean, stable MVP with scalable architecture. The goal is to launch a solid first version and iterate in future phases.
Core Requirements
Full integration with CS-Cart Multi-Vendor
Consumption of existing REST APIs
Creation of additional endpoints only if required for mobile support
Real-time synchronization of products, users, and orders
Secure authentication aligned with the web platform
Scalable, modular mobile architecture designed for future expansion
MVP Scope (Phase 1 – Buyer App Only)
User registration and login
Product browsing (categories, search, filters)
Product detail view
Shopping cart
Checkout process (integrated with existing backend logic)
Order history and order status tracking
User profile management
Push notifications for key events (e.g., order updates)
This phase focuses exclusively on buyer functionality. Vendor/admin features, advanced personalization, and complex add-ons are out of scope for the initial release and may be considered in later phases.
Ideal Candidate
We are looking for a developer or team with:
Proven experience building mobile apps integrated with e-commerce backends
Strong REST API integration expertise
Experience working with marketplace or multi-vendor systems
Published apps in the App Store and/or Google Play
Please include:
Your proposed technology stack (e.g., Flutter, React Native, or native)
Estimated timeline for MVP completion
A detailed and realistic budget proposal based strictly on the defined MVP scope
We value clean architecture, strong communication, and practical execution focused on delivering a stable first release.
If the collaboration is successful, there will be opportunities for continued development in Phase 2 and beyond.
