POS System Guide 2025: Types, Features, Costs, How It Works

More than 78% of retailers now rely on a POS system to run daily operations. A POS system is the tool a business uses to record sales, accept payments, and manage tasks from one place. In 2025, modern POS systems are cloud-based, fast, and easy to use, helping shops, cafés, and salons work smarter with real-time data.

What Is a POS System? (Simple Definition)

A POS system is the technology a business uses to process sales, accept payments, track inventory, and manage operations. Think of it as the digital hub where every sale begins and every business decision becomes clearer.

A POS system includes:

POS software
Touchscreen terminal or tablet
Payment terminal
Barcode scanner
Receipt printer
Inventory & analytics dashboard

Businesses use POS systems to improve speed, accuracy, customer experience, and overall efficiency.

How Does a POS System Work?

A POS system follows a standard workflow:

1. Product is added or scanned

The POS fetches item details, pricing, discounts, and taxes.

2. Customer chooses a payment method

Card, cash, tap-and-pay, QR, eWallet, or invoice.

3. Payment is processed & verified

The POS communicates with the payment gateway.

4. Receipt is generated

Email, SMS, or printed.

5. Inventory updates instantly

Stock levels drop automatically.

6. Sales data syncs to the cloud

You can view reports anytime on any device.

From a simple coffee purchase to complex multi-branch operations, the process stays the same.
