Inventory Management System for Timex Garments

Stock at Timex Garments was tracked by hand in spreadsheets, with no audit trail, no alerts and slow reporting.
Approach
Built a PHP/MySQL system with role-based access, transaction-based stock history, low-stock alerts and PDF reports.
Result
Cut manual stock-tracking time by 40% and gave every stock movement a full audit trail.
