E-commerce Inventory & POS System Built with Google Sheets + Apps Script

Stop paying for expensive inventory management software. This system gives you a complete, customizable e-commerce inventory and sales solution built entirely on tools you probably already have: Google Sheets as your database and Google Apps Script as the backend, with the interface generated using Google AI Studio.

Track stock levels, manage products and categories, process sales through a built-in Point of Sale (POS), consolidate orders from multiple sales channels, manage purchase orders and suppliers, and generate PDF invoices — all from a system you fully own and can customize to match your exact workflow, instead of adapting your business to someone else's software.

Because it runs on Google Sheets and Apps Script, there's no vendor lock-in, no recurring subscription fee, and no limits imposed by a third-party platform. You control the data, the logic, and the interface.
