Cloud Retail Point of Sale (POS) System

Q: Does this Cloud POS work during internet outages?

Yes, 100%. The application is built as a Progressive Web App (PWA) with a local IndexedDB cache. You can scan barcodes, ring up sales, and print thermal receipts completely offline. The moment an internet connection is detected, sales auto-sync to the central PostgreSQL database.

Q: How does automated Daraja M-Pesa STK work at the register?

When the cashier selects M-Pesa, the system triggers an instantaneous Lipa na M-Pesa STK push to the customer's phone. Upon entering their PIN, Safaricom's webhook verifies the transaction in under 2 seconds, auto-clearing the order and triggering the receipt printer.

Q: What receipt printers and barcode scanners are supported?

It natively supports all standard 58mm and 80mm USB and Bluetooth ESC/POS thermal printers (such as Xprinter, Epson, and Posiflex) as well as handheld 1D/2D USB/Bluetooth laser barcode scanners.

Q: Can I run multiple branches or warehouses?

Yes. The backend architecture includes multi-branch inventory tracking, inter-branch stock transfers, cashier shift reconciliation, and role-based permissions (RBAC) to prevent staff theft.

High-velocity retail management with offline-first PWA sync, hardware barcode scanning, automated M-Pesa STK prompts, and multi-branch inventory tracking designed for Kenyan retail chains.
