• Purchasing: Register supplier invoices to replenish stock.
• Reporting: Real-time insights on Sales, Stock Levels, and Top Selling Products.
• Clean UI: Modern dark/light interface built with CSS-styled JavaFX.

• Language: Java 17
• UI Framework: JavaFX 21 (Modular)
• Database: MySQL 8.0
• Persistence: JDBC (Raw SQL for performance and control) with HikariCP Connection Pooling.
• Architecture: Hexagonal / Clean Architecture (Domain, Infrastructure, UI separation).
• Build Tool: Maven
