Interactive Supply Chain Management & Inventory System with Visual Relationship Mapping - TradeLink Pro
Visual Procurement & Relationship Mapping System with drag-and-drop interface that enables real-time visualization of supplier-product-customer relationships through interactive tree structures.
Project Summary
Developed a custom drag-and-drop procurement relationship management system for TradeLink Pro that visualizes suppliers, products, and customers in a real-time interactive tree structure. Built with a Laravel backend and custom D3.js frontend, the system enables users to dynamically assign relationships and instantly see supply chains in a visual format—dramatically improving traceability, clarity, and supplier/customer assignment workflows.
About TradeLink Pro
TradeLink Pro is an emerging B2B tool in the procurement and supply chain domain. It enables small to mid-size manufacturers, resellers, and wholesalers to efficiently manage their supplier-product-customer ecosystem.
The core pain point for these businesses is managing and visualizing complex product ownership chains—where one product may be provided by multiple suppliers and bought by multiple customers. Traditional ERP systems are either too expensive or too rigid to offer the kind of flexible, visual flow mapping that TradeLink Pro aims to deliver.
The Challenge
"We want to see how our products flow—who supplies them, and who buys them—using a drag-and-drop visual system that updates in real-time."
Visual Relationship Mapping
Need a visual method to explore relationships between suppliers, products, and customers.
Flexible Interface
A drag-and-drop interface to assign or unassign entities without clunky forms.
Product Traceability
A traceability map for each product to answer: where it comes from, and where it goes.
Real-time Logic
Bi-directional logic: selecting entities reveals all related connections instantly.
Solution Approach
Relational Design & API Layer (Laravel)
Designed an Eloquent-based schema with RESTful API endpoints for fetching tree data, creating/deleting links, and handling permissions.
Visual Interface (D3.js-based)
Developed a bidirectional tree view with drag-and-drop interfaces, real-time animations, and clickable nodes with logos and tooltips.
Smart UX for Complex Actions
Implemented instant unassignment controls, auto-aligning trees, hover actions, and real-time re-rendering for smooth usability.
