If you're looking to upgrade your business's payment processing system, then you've probably heard of the term 'POS' or 'ePOS', and are asking: 'what is a POS system'?
A POS system, also commonly referred to as an ePOS or point of sale system, is a combination of hardware and software which enables you to take payment for products or services at your physical or online business.
POS hardware typically takes the form of a card reader, register, or tablet, while the software links everything together and has functions for managing inventory, staff, and customer data. But more on that later.
As a merchant, you likely have a physical-front store, online shop—or indeed, both—and need a commercial system that can process payments or refunds quickly and record transaction history accurately. Sounds simple enough, right?
When you start to think about how these situations can play out in detail, from tourists paying with different card types and currency, to loyal customers paying with a mix of cash, store credit, or gift voucher, a simple sale gets a little trickier to process.
POS systems: more than just a point of sale
A POS system is designed exactly for this complexity. They are equipped to deal with all customer needs at the point of sale, from sending email gift receipts to reminding you of current promotions to boost sales.
When used effectively POS systems are capable of driving down cost and improving margins without sacrificing service levels. There’s tons to choose from, and in our roundup of the best point of sale systems, Shopify, Square and Vend topped our list of recommendations.
POS systems also offer you business insight to keep operations smooth and highlight areas for development. They can alert you when inventory is running low, notify you, ensure you're keeping on top of compliance-related payment regulations, and help your business avoid fines and other administrative costs (such as chargeback fraud), all while offering advanced security features that protect from data theft and cyber breaches.
Point of sale systems are sometimes used to refer to the cash register, or even called a POS cash register. The reality is that they're much more than the old fashioned cash register. In today’s world, modern digital POS systems give your business an edge, and let you check out customers from wherever your business is based.

In choosing a POS system, you will need to consider upfront what specific features and customization options your business needs. Example scenarios:
Retail business owner
Retailers that sell electronic goods will need their products to contain serial numbers to identify models, makes, and specific items in stores.
Online fashion business owner
Clothes retailers, on the other hand, will need their products to have separate brand-specific SKUs. Due to the high associated costs of items, jewelry stores will have POS systems that specifically issue alerts for incorrect billing attempts.
Convenience corner store owner
And for groceries, point-of-sale systems require goods to contain both sell-by dates and a unit of measurement in order to allow companies to sell items at a discount once.
Elements of a POS system
The Modern POS systems have evolved from simple cash registers and can do much more than simple transactions. They are ubiquitous in many sectors – hospitality, retail, and leisure – and come in different shapes and sizes depending on the needs of the business.
Some POS systems combine hardware (such as a server computer) and software in a single unit, whereas others separate the two by connecting a ‘dumb’ terminal to a server located either on-premise or in another building.
Combination POS systems
Some POS systems combine hardware (such as a server computer) and software in a single unit, whereas others separate the two by connecting a ‘dumb’ terminal to a server located either on-premise or in another building. For cloud-based POS systems, terminals connect directly to the internet to run software that updates automatically.
Modular POS systems
Many are modular, allowing additional hardware units to be connected for displaying metrics such as order total and product weight. Others can scan barcodes, print receipts and handle security needs – for example, credit card processing systems designed for taking credit or debit card payments.
POS systems are also customizable on the software side, allowing businesses to manage membership programs and loyalty schemes to grant customers discounts on future purchases. Here, UX and design become critical to their effectiveness.
Terminals in restaurants, for example, will prioritize usability and speed by featuring enlarged buttons on big and bright monitors to make it quick and easy for staff to book tables for customers in dark environments.
Handheld POS systems
Conversely, a handheld EPOS (Electronic Point of Sale) terminal on a market stand will be barely bigger than a credit card while featuring the ability to house a 4G SIM card for connecting directly to the internet to process payments online.

POS systems: beyond transactions
A POS system can reduce reliance on manual processes, making it a vital tool in helping businesses to digitize their processes and reduce reliance on spreadsheets. Powerful POS solutions excel in providing real-time, actionable data that enables tasks to be undertaken efficiently and quickly.
✔ POS systems are perfect for getting to know customers better
This includes the ability to store information and build customer profiles to understand more about customers. This in turn leads to better marketing capabilities such as the ability to create customer groups – for example VIP shoppers – that can be targeted through direct marketing campaigns.
✔ Monitor employee performance
At same time, POS systems allow you to find out about your own employees’ performance by letting customers tip your workers using pre-set percentages, which is especially useful for companies in the service industry.
✔ Track product and sales reports with ease
And when it comes to reporting, POS systems can tell you when certain items are becoming more popular while helping you to ensure that you have a sufficient amount of them in your inventory. It can be achieved through digitised product catalogues in systems that track inventory and automatically updating quantities as buyers purchase them.
