Executive Summary
Platinum Stitch is an enterprise manufacturing management system for textile and apparel production. It streamlines operations from order management to production tracking, employee management, and reporting. Built with Next.js 14, TypeScript, and Supabase, it provides a scalable, secure, and performant solution for manufacturing operations.
The Problem
Previously, the company maintained all records on Excel, which was very difficult to track. This manual spreadsheet-based approach created significant operational challenges:
1. Excel-Based Record Management Challenges
- All company records maintained in Excel spreadsheets, making tracking extremely difficult
- Manual data entry prone to errors and inconsistencies
- No centralized system for real-time updates across departments
- Difficulty in searching, filtering, and analyzing historical data
- Version control issues with multiple spreadsheets being shared and edited
2. Inefficient Order Management
- Complex purchase order workflows
- Manual tracking of production stages
- Limited visibility into order status and progress
3. Resource Management Challenges
- Employee attendance tracking across departments and units
- Work assignment and allocation
- Performance monitoring and reporting
4. Data Integrity & Security Concerns
- Inconsistent data entry
- Limited access controls
- No centralized audit trails
5. Performance & Scalability Issues
- Slow navigation and page loads
- Poor user experience on large datasets
- Limited ability to scale operations
