How mazharali-12/shopbillingsystem-java works
Shop Retail Billing System is a Java Swing desktop application for retail inventory, customer credit, supplier management, sales billing, and payment history. A shop operator works through the GUI to manage stock and customers, create discounted bills with cash-and-credit payments, and settle outstanding dues; managers coordinate business logic and JDBC persistence. MySQL supplies the durable records and documented trigger-based stock automation. The sampled source shows billing transactions, dues settlement, and manager-to-database calls; several GUI and database operations are only partially excerpted, so those relationships are omitted where not evidenced.
