I’m ready to launch a full-featured e-commerce site that handles physical goods, digital downloads, and service bookings under one roof. To make this work smoothly for every stakeholder I need three separate yet connected portals: • End-User Panel – clean storefront, secure checkout, account dashboard, order tracking, wish-list, and any other retention tools you normally see on a mature e-commerce site. • Salesman Panel – each salesperson should be able to generate and share unique referral codes, monitor commission earned on every product, and see a wallet balance that updates only after an order is delivered successfully. • Admin Panel – product & inventory management for all item types, adjustable commission rules, advanced sales analytics, and a simple interface for answering customer queries. Key expectations • One codebase powering all three panels, mobile-responsive from the start. • Support for multiple payment gateways and real-time shipping/digital-delivery handling. • Secure user authentication, clean database design, and clear separation of permissions (admin vs. salesman vs. customer). • Well-documented code plus a short hand-off session so my in-house team can manage day-to-day tasks. When you deliver I will test: 1. Referral code flow from issuance to commission credit. 2. Complete transaction journey for each product type. 3. Accuracy of analytics and inventory data in the admin dashboard. If you’ve built similar multi-role e-commerce systems before, please share a live link or repo snippet so I can see your approach.
