I am ready to launch an online marketplace focused exclusively on cotton textiles and need a fully custom-built solution rather than an off-the-shelf platform like Shopify or Magento. The site must scale smoothly as new sellers join, while giving each vendor a straightforward way to upload catalogues, track orders, and manage inventory from both a browser-based dashboard and a companion mobile app. Core functionality I expect from day one: • Vendor management system that lets me approve, suspend, and analyse each seller’s performance. • Robust product search and filtering so buyers can drill down by fabric type, GSM, weave, colour, and price. • Secure, multi-currency payment gateway integration with split payouts to vendors. Behind the scenes, clean code, modular architecture, and well-documented APIs are essential so I can add features such as logistics integrations or analytics down the line without tearing everything apart. Deliverables I need to sign off the project: 1. Responsive web marketplace with all listed features working end-to-end. 2. iOS and Android vendor apps mirroring the web dashboard’s capabilities. 3. Source code repository with README, environment setup, and deployment scripts. 4. Short video walk-through plus live staging URL for acceptance testing. If this aligns with your expertise in custom marketplace development, let’s discuss the tech stack and a phased roll-out plan.
