Build me a modern point of sale app for a small business, something that can work for a shop, café, restaurant, or warehouse. I want a clean dashboard where I can manage products, categories, customers, taxes, sales, payments, receipts, refunds, and stock in one place. It should also handle inventory history, low stock alerts, purchasing, reports, staff roles, permissions, and activity tracking.

Make it feel like a real business tool, with a polished admin interface and a fast checkout flow. I’d like it to support barcode scanning, register management, customer rewards and coupons, and a modular setup so extra features can be added later without rewriting the core. If helpful, use current docs online for anything that has changed recently.

Please include a basic setup flow, a few sensible sample records, and make sure the app is ready to run locally and extend later for things like restaurant tables or bookings through modules.
