GadgetOS

GadgetOS is an offline-first point-of-sale and shop-management app built for electronics and gadget retailers. Ring up sales at the counter, capture serial/IMEI numbers at the point of sale, track manufacturer warranty and RMA, manage suppliers and multi-branch stock, and print compliant VAT (Mushak) receipts — all from one app that keeps working even when your internet doesn't. Every shop also gets its own online storefront website automatically — no setup, no web developer. When you sign up, GadgetOS instantly creates a ready-to-sell store at your own web address, styled to match your shop, so your customers can browse your products online from day one. Runs on Android, iOS, Windows, macOS, and the web, so your counter, back office, online store, and owner dashboard all stay in sync. KEY FEATURES • Free online storefront — an automatic, ready-made website for your shop at your own address, kept in sync with your in-store stock. • Fast counter POS — barcode scanning, quick product search, cash/card/mobile-wallet payment methods, and 58mm or 80mm thermal receipt printing. • Serial & IMEI capture — record IMEI/serial numbers at sale for phones and serialized devices, with used/refurbished unit tracking. • Warranty & RMA — log manufacturer warranty periods and manage repair/return (RMA) workflows. • Inventory & multi-branch stock — real-time stock across branches, opening-stock intake, and low-stock visibility. • Spec-rich catalog — a detailed product catalog tailored to electronics and gadgets. • Suppliers & purchasing — manage suppliers, purchase orders, and costs. • VAT / Mushak compliance — itemized VAT receipts with your business name, BIN, TIN, and address for NBR requirements. • 0% EMI support — record installment/EMI sales. • Offline-first — sales and inventory work without a connection and sync automatically when you're back online. • Bangla & English — full bilingual interface, Asia/Dhaka timezone.
