You’ve undoubtedly seen the store owner using a tiny device to accept card or UPI payments when you enter a store, restaurant, or even a petrol pump. The term “POS system” refers to both the hardware and the software that powers it.
POS stands for Point of Sale, which simply means the place where a sale happens — where the customer pays and the business receives money.
In the past, sales were recorded using calculators and manual registers. However, POS systems, which combine hardware and software, are now used by modern businesses to streamline and expedite billing, payment, and reporting.
A POS system helps businesses handle transactions, track inventory, generate invoices, and even manage customers — all in one place.
Hence, a point-of-sale system can streamline the day-to-day operations of any business, be it a supermarket, restaurant, or small retail store.
What Exactly is a POS (Point of Sale) System?
A Point of Sale (POS) system is a combination of tools used to complete a sale and record payment details. It includes:
- POS Machine (Hardware) the device used to swipe cards or scan QR codes.
- POS Software – the system that calculates totals, applies taxes or discounts, and records the sale.
When a customer pays for goods or services, the POS system records the payment, updates the inventory, and generates a bill instantly
So, in short, a POS system is where your customer makes a payment and your business records it — whether offline in a store or online through a website.
Different Types of POS Systems Used by Businesses
POS systems are available in a variety of configurations based on the size and nature of the company. Let’s understand the most common types:
1. Traditional POS (On-Premise)
These are computer-based point-of-sale systems that are set up in the physical store. Large retail establishments and restaurants are their primary users, and they typically require a server.
2. Cloud-Based POS
This modern POS is fully online. You can use your laptop or phone to access data, sales, and reports from any location. For small and medium-sized enterprises, it is perfect.
3. Mobile POS (mPOS)
Mobile point-of-sale (mPOS) systems are app-based and compatible with tablets and smartphones. They’re easy to carry and perfect for delivery-based or quick-service businesses.
4. Self-Service POS
Used in supermarkets or movie theatres where customers can scan and pay themselves without a cashier.
5. Tablet POS
These use a tablet as the main device, often seen in cafes or pop-up stores. They are stylish, affordable, and simple to set up.
Each POS system has its own features, so the right choice depends on how your business operates.
How Does a POS System Actually Work?
The working of a POS system is quite simple, but it happens in a few quick steps:
1. Customer selects a product or service
The billing process begins when a customer decides to buy something.
2. POS software calculates the total amount
It adds the product prices, includes GST or other taxes, and shows the final amount to pay.
3. Customer chooses the payment method
Payment can be made using debit/credit cards, UPI, wallets, or cash.
4. POS system processes the payment
Once payment is made, the POS verifies it through a bank or payment gateway and confirms the transaction.
5. Receipt generation and data storage
A bill is printed or sent digitally, and the transaction details are saved in the system for reports and accounting.
This entire process happens within seconds, helping businesses handle hundreds of customers every day smoothly.
