QuPOS works with ordinary hardware: a Windows PC, any keyboard-mode barcode scanner and any printer with a Windows driver. Here is what each device does, what to look for when you buy, and suggested setups for each type of shop.
Start with what you need on day one; you can add a label printer or a scale later without changing anything in QuPOS.
General stores, stationery, hardware, footwear, gift and medical-accessory shops
Add a label printer if many of your items have no maker barcode.
Grocery, kirana and departmental stores, one or more counters
For two or more counters, every counter gets a PC, scanner and printer, and one PC (on a UPS) holds the shared SQL Server database.
Sarees, readymade garments, fabric by the metre, footwear
A label printer matters most here: every size and colour of a style gets its own barcode label.
Phones, accessories and service counters
Choose a 2D scanner so IMEI barcodes on phone boxes read in one go. A 2-inch printer is enough for accessory-only counters.
Any Windows 10 or Windows 11 64-bit PC with 4 GB RAM and 300 MB free disk space runs QuPOS. An all-in-one PC or a small desktop saves counter space.
QuPOS reads barcodes as typed keystrokes followed by Enter, the factory setting of almost every retail scanner. Plug it in and scan; there is nothing to install.
QuPOS prints bills through the Windows printer driver, so any 2-inch (58 mm) or 3-inch (80 mm) thermal receipt printer with a Windows driver works. Bills print silently, without a print dialog.
For full tax invoices to business customers, and for A4 barcode label sheets. Any home or office A4 printer (laser or inkjet) works.
Prints price and barcode labels for loose, unbranded or textile items. Any label printer with a Windows driver works with label rolls of 50×25 mm, 38×25 mm, or 2-up and 3-up rolls.
For rice, sugar, dal, vegetables and sweets. The scale weighs the item and prints a barcode with the item code and weight; the cashier scans it and QuPOS Supermarket adds the item and weight together.
A cash drawer usually plugs into the thermal printer (RJ11/RJ12 "DK" port), not the PC. Most printer drivers have a setting to open the drawer when a bill prints.
A power cut in the middle of a save is the most common cause of data trouble. A small UPS keeps the PC (and the SQL Server PC for several counters) running long enough to finish. A USB drive or cloud-synced folder holds the automatic daily backup.
No. QuPOS runs on an ordinary Windows 10 or 11 PC, reads any keyboard-mode barcode scanner, and prints through Windows to any printer that has a Windows driver. Use the printer and scanner you already have if they work in Windows.
Any 2-inch (58 mm) or 3-inch (80 mm) thermal receipt printer with a Windows driver. Install the driver, print a Windows test page, then select the printer in QuPOS under Settings → Printing for silent printing.
Yes, with label-printing scales. The scale prints a barcode with the item code and weight, and the Supermarket business type reads it in one scan. QuPOS does not read the weight from a scale over a cable.
No. Qubha supplies the software only, so you can buy hardware from any local dealer or online. Message us on WhatsApp before you buy and we will tell you what to look for.
