SalesBoard is an all-in-one business management web application for small businesses and self-employed professionals, developed as my Bachelor's Final Project and awarded the highest distinction. Many businesses manage sales, invoicing, and inventory using separate, disconnected tools. SalesBoard brings all these processes together in a single platform. The application allows users to manage sales, bookings, returns, payments, and discounts, as well as products, services, stock levels, and inventory movements. It also includes customer, supplier, and employee management, along with a dashboard featuring metrics on business performance. Throughout the development process, the application was tested with real businesses and improved iteratively based on their feedback.
