A POS (Point of Sale) system is the technology that businesses use to process customer transactions. It is where your customer makes a payment for goods or services: the point of sale. Modern POS systems go far beyond simply processing payments. They typically include inventory management, sales reporting, customer management and employee tools all in one platform.
In the UK, POS systems range from simple card payment terminals to comprehensive cloud-based platforms. The market has shifted significantly in recent years from traditional hardware-based till systems to software-driven solutions that run on phones, tablets and laptops. This shift has made POS systems more affordable and accessible for small businesses.
For UK small businesses, a modern POS system can replace multiple separate tools: the till, the inventory spreadsheet, the customer database and the sales reporting dashboard. By consolidating these functions into one platform, businesses save time, reduce errors and gain better insight into their operations.
Types of POS Systems
Traditional POS
Hardware-based systems with dedicated terminals, cash drawers and receipt printers. Typically installed on-site with local software. Higher upfront cost, limited flexibility.
Best for: Established retail stores with fixed checkouts.
Cloud-Based POS
Software that runs in a web browser on any device. Data stored in the cloud, accessible from anywhere. Lower upfront cost, automatic updates, works on existing devices.
Best for: Small businesses, multi-location, mobile traders.
Mobile POS (mPOS)
Smartphone or tablet-based POS systems. Process payments anywhere using QR codes or card readers. Minimal hardware required. Highly portable.
Best for: Market traders, pop-up shops, service businesses.
All-in-One POS
Complete platforms that combine POS with inventory, CRM, invoicing and payments. Replaces multiple separate tools with one integrated system.
Best for: Growing businesses wanting to consolidate tools.
Key Features to Look For
Fast Checkout
The POS should process transactions quickly with barcode scanning, product search and quick-pay options. Slow checkout frustrates customers and queues.
Inventory Sync
Every sale should automatically update stock levels. Without this, you are managing inventory separately from sales, leading to errors and overselling.
Payment Processing
Integrated card payments eliminate the need for a separate terminal. Look for support for contactless, chip, Apple Pay and Google Pay.
Sales Reporting
Daily, weekly and monthly sales reports help you understand performance, track trends and make better business decisions.
Multi-User Access
Multiple staff members should be able to use the system simultaneously with role-based permissions for managers and cashiers.

Hardware vs Software: What Do You Actually Need?
One of the biggest decisions when choosing a POS system is whether you need dedicated hardware. Traditional POS systems require a terminal, cash drawer, receipt printer and card reader: easily £500-£1,000 in upfront costs. Modern cloud-based POS systems like Aphelios run on the devices you already own, eliminating hardware costs entirely.
For most UK small businesses, a smartphone or tablet-based POS is sufficient. You can accept payments via QR codes or payment links without any card reader at all. If you prefer a card reader for chip and contactless payments, Stripe terminals integrate seamlessly with Aphelios at reasonable prices.
The only businesses that truly need dedicated POS hardware are high-volume retail stores processing hundreds of transactions per day. For everyone else: market traders, cafes, service businesses, pop-up shops: a software-based POS on a tablet or phone is the most cost-effective solution.
How to Choose the Right POS System
Step 1: Identify Your Must-Have Features
Start by listing the features you cannot operate without. Do you need inventory management? CRM? Multi-location support? Employee scheduling? Your must-have list narrows down the options quickly.
Step 2: Set Your Budget
Consider both upfront costs (hardware, setup fees) and ongoing costs (monthly subscriptions, transaction fees). A free POS with competitive transaction fees often costs less than a paid POS with lower fees.
Step 3: Consider Your Business Type
Different businesses have different needs. A retail shop needs barcode scanning and inventory management. A cafe needs table management and quick checkout. A market trader needs portability and offline capability.
Step 4: Test Before You Commit
Most POS providers offer free trials. Use them. Process test transactions, check the reporting, try the inventory features. Make sure the system works for your specific workflow before committing.
