Inventory Manager is a lightweight, secure, and robust inventory management system developed specifically for small businesses, shops, or individual users who require an offline-first solution. Built with Python, Streamlit, and a powerful SQLite database backend, this application allows you to manage your product catalog and inventory movements without the need for an internet connection or expensive cloud subscriptions.
It features an intuitive web-based interface that makes tracking stock levels, unit prices, and transaction histories simple and efficient. The backend leverages the Data Access Object (DAO) pattern to ensure code maintainability, and it utilizes atomic SQL transactions to guarantee data integrity during every stock update. This template is fully documented and ready to deploy, making it an excellent starting point for developers looking to build or integrate custom inventory solutions. Whether you are managing retail stock, office supplies, or specialized equipment, this tool provides the audit trail and control you need to run your operations smoothly and reliably.
