Many POS systems can function across your physical and eCommerce store so that you can manage your entire business on one platform. Whilst payment processing is the core function of a POS system, the best systems can cover so much more.

To oversee the various components of your business, opt for a POS system with advanced features like inventory, customer and employee management tools. We’ve put together this advanced guide to POS systems to break down how to find the perfect system for your business.


Introduction to POS Systems

POS stands for point of sale and refers to the system that facilitates ringing up sales. This includes all the hardware and software used to accept payments and track sales.

Gone are the days when a POS system only included the site where customers physically bought goods and services, e.g. the cash register. Thanks to immense technological advancements, POS systems nowadays encompass much more.

Any hardware connected to your POS becomes part of that complex system. For example, tablets are used by waiting staff to take orders. Not only this, but the software installed on that hardware is also part of the POS system, such as payment processing software.


Benefits of a POS system

Today’s hassle-free POS solutions automate much of the workload, from processing sales to managing inventory. Automation frees up vital employee time, increasing efficiency and maximising profits.

Using the top POS hardware and software in unison means you can sell your products and services securely and seamlessly. Transactional data is then stored in your POS system, which can be used to formulate reports and gain actionable insights.

However, a POS system’s capabilities are not limited to processing sales. You can also rely on POS technology to cover every aspect of business management. For example, inventory management, accounting, reporting, customer relationship management, and more.

Different Types of POS Systems

These are the main types of POS systems.

1. Traditional POS System

The traditional POS system is also known as an on-premise or legacy POS system. All the hardware and software are installed within, and limited to, the walls of your physical store.

This POS system runs on closed networks and relies on local servers, meaning you can only access sales data when you’re physically in store. Maintenance and updates are handled manually, and costs can be high.

However, it remains a popular choice among business owners. A key advantage is that traditional POS systems tend to be large and robust, meaning theft or damage is far less likely.

2. Cloud-based POS System

Cloud-based POS systems store all your data online, meaning you can manage aspects of your business from anywhere. All you need to do is log into an internet-connected device, and you can use your integrated software tools on the go.

Not only does a cloud-based POS system securely store your data, but it also automatically updates software and functions even when you’re offline. If you lose Wi-Fi, your data is protected, and any sales processed are automatically updated when you regain connection.

There are minimal upfront costs involved with cloud-based POS systems, and payment plans are often affordable. The preferred choice of most business owners is a cloud-based system because of its mobility and accessibility.

3. Mobile POS Systems

Any mobile device or tablet can function as a point of sale and connect to the cloud. Most POS software works seamlessly on mobile devices, meaning an mPOS is a flexible and efficient solution.

Mobile POS systems aren’t tethered to your counter, meaning employees are free to circulate your store while serving customers. There are no hidden installation costs, and mobile POS systems are user-friendly.

4. Self-Service Kiosks

Self-service kiosks allow customers to self-checkout. They’re prevalent because they reduce waiting times and labour costs. Many large retail stores and fast service restaurants opt for self-service kiosks to streamline daily operations.

Many customers prefer self-service kiosks and feel they provide a more pleasant shopping or dining experience. They also benefit employees, who can spend more time on other important tasks.

5. All-in-one POS systems

All-in-one POS systems consolidate the disparate POS elements into one. Some providers offer a package containing the required hardware and pre-integrated software. An all-in-one system is an ideal choice to synchronise all your POS applications effortlessly.

Having everything you need on one operating system streamlines business management significantly. There’s no risk of software incompatibility or miscommunication. Instead, you simply set up your POS hardware, and you’re ready to go.

The only slight disadvantage is that if the system goes down, this affects your business more. However, you only have to refer to one provider for customer support, and these systems are pretty advanced and reliable.

Who Should use a POS System?

POS systems can benefit F&B, retail and professional service businesses of all sizes.


Industry-specific POS solutions can be a great option because they offer services relevant to your business type.

POS systems tailored toward restaurants, bars, and cafes prioritise table and menu management features. In contrast, systems built for the retail world may come with barcode scanners for checkout. Some systems specialise in managing client appointments for those running a professional service, like a salon.

For fully digitized businesses, eCommerce POS systems contain vital design tools to help you build a beautiful website. Leading POS solutions can bridge your online and physical stores to consolidate inventory and provide an omnichannel experience.


If you own a large business or enterprise, there are POS systems built to operate in multiple locations. Look for a system that can synchronise data across multiple sites, manage a large workforce, and serve a high volume of customers.

Small business owners shouldn’t necessarily invest in a POS system bursting with advanced features. Going for a smaller, simple design could be more cost-effective and instead dedicate your profits to other business areas.


Components of a POS System

A POS typically comprises an internet-enabled device to act as a monitor and various accessories to help with the basic process of exchanging money for goods. The hardware you choose to adopt will depend on the type of business you run and how you wish to manage transactions.

Kitchen printers are used to print out order tickets in restaurants to simplify food preparation. They can be beneficial, but many business owners opt for a digital approach with a kitchen screen display.

Card Readers

Having a credit card reader is more crucial than ever in today’s cashless world. Card readers allow you to accept payments via credit and debit cards or mobile wallets. Modern solutions are wireless, compact, and can be used on or off-premises.

Cash Drawers

For peace of mind, it’s vital to have a cash drawer with enhanced security features. Most businesses choose to have a cash register only accessible to employees and controlled via the monitor.

A cash register is not necessarily an essential piece of hardware since many businesses only accept card payments. Ditching the traditional cash drawer could save a great deal of time but potentially risk isolating specific customers.

  • Barcode scanners.
  • Additional tablets/mobile devices.
  • Digital menus.
  • Bluetooth scales.
