Inventory Management and Purchasing

Provides an end-to-end inventory management ecosystem featuring customizable role-based permissions, requisition approval pipelines, and automated purchase order generation.

Drastically improves operational efficiency, auditability, and real-time inventory visibility across departments.

01.THE CHALLENGE

The organization relied on fragmented, unvalidated Excel files across multiple departments to manage purchasing and stock levels. This created severe information silos, delayed authorization cycles, lack of audit trails, and frequent stockout or auditing errors.

02.THE SOLUTION

Architected a full-stack web application leveraging Next.js for server-rendered interfaces and API routes, backed by a relational MySQL database. Implemented a granular Role-Based Access Control (RBAC) authorization system to handle multi-tier approval workflows, automated status transitions, and real-time stock adjustments.

03.ARCHITECTURE & DESIGN

• ▹Next.js architecture combining Server-Side Rendering (SSR) and internal API routes for secure data fetching.
• ▹Normalized MySQL relational database design enforcing transactional integrity (ACID) during inventory updates.
• ▹Custom RBAC middleware ensuring strict role authorization (Requisitioner, Department Manager, Purchasing Admin).
• ▹Modular SASS design system providing responsive data tables, status badges, and management dashboards.

04.KEY FEATURES

• ⚡Multi-tier requisition & purchase order workflow with role-specific authorization rules.
• ⚡Real-time inventory level tracking with dynamic stock adjustment and threshold alerts.
• ⚡Comprehensive audit logging tracking status changes, timestamps, and approving users.

05.IMPACT & RESULTS

• ✦Eliminated manual Excel tracking, centralizing purchasing operations into a single source of truth.
