This practical program shows how to turn a Google Sheet into a functional mobile inventory app with AppSheet, without traditional coding. Learners will create a structured inventory database, use Google Gemini to generate starter data, connect stock transactions with SUMIFS formulas, and configure AppSheet tables, keys, forms, and views. The program also covers live two-way synchronization, field rules such as default dates and required inputs, secure access, and sharing an app with a small team. By the end, participants can build and deploy a professional inventory management system for a micro-enterprise or training environment.
