Understanding EPOS systems

An Electronic Point of Sale (EPOS) system is a combination of hardware and software that helps businesses process transactions, track sales and inventory, and manage many other commercial functions.

This powerful tool can streamline your operations, reduce manual errors and provide useful business insights. But with a plethora of EPOS systems on the market, it can be quite a challenge to choose the right one for your business.

Let’s explore what EPOS systems are and how you can select the one that will best meet your needs.

The role of an EPOS system in a business

At its core, an EPOS system is essentially the digital version of traditional cash registers. However, modern EPOS systems do far more than just process transactions.

They can integrate with your inventory systems, generate sales reports, track customer habits, manage employees, and even help with marketing strategies.

In essence, an EPOS system can handle multiple aspects of your business, leading to increased efficiency and improved decision-making.

Types of EPOS systems compared

There are several different types of EPOS systems available, each offering unique features and benefits that cater to different kinds of businesses. Here, we will compare the main types of EPOS systems: on-premise EPOS systems, cloud-based EPOS systems, and mobile EPOS systems.

On-premise EPOS systems

On-premise EPOS systems are installed locally on your business’s hardware and servers and are managed by your IT staff. This traditional type of EPOS system usually involves a high initial investment but can be cost-effective in the long run as there are typically fewer ongoing fees.


  • Greater control over your data
  • Usually more customisable
  • No reliance on an internet connection


  • High upfront costs
  • Requires dedicated IT staff for maintenance and updates
  • Less flexible and harder to scale

Cloud-based EPOS systems

Cloud-based EPOS systems, also known as Software as a Service (SaaS), are hosted on the vendor’s servers and accessed through the internet. They typically operate on a subscription model with monthly or annual fees.


  • Lower initial costs
  • Easy to scale and update
  • Accessible from anywhere with an internet connection


  • Ongoing subscription costs
  • Dependence on a reliable internet connection
  • Potentially less control over your data

Mobile EPOS systems

Mobile EPOS systems, often known as mPOS systems, operate on a smartphone or tablet, making them a flexible solution for businesses that need to process transactions on the go, like market stalls, pop-up shops, or mobile food vendors.


  • High flexibility and portability
  • Lower cost than traditional systems
  • Easy to set up and use


  • May lack advanced features of larger systems
  • Dependence on a reliable mobile data or Wi-Fi connection
  • May require additional hardware for printing receipts

It’s worth noting that many businesses often opt for a hybrid solution, combining elements of the different types to best meet their needs.

For instance, a restaurant might use an on-premise EPOS system in their main location, but use a mobile EPOS system for their pop-up events. As always, the choice of EPOS system will depend on your specific business needs and circumstances.

Factors to consider when choosing an EPOS system

Business needs

Before you start shopping around for an EPOS system, first establish what you need the system to do. Are you looking to streamline transactions, or do you want to integrate it with your inventory system? Are customer loyalty programmes or employee management features important to you? Your specific business needs will guide you in determining which EPOS system is the right fit.


The user-friendliness of an EPOS system is paramount. If it’s too complex, you could face a steep learning curve, leading to lost time and productivity. Test drive a few systems before deciding on one.

Ask your employees to use it as well – after all, they will be the ones interacting with it regularly. Look for systems that have intuitive interfaces, clear instructions and offer solid customer support.


EPOS systems can be a significant investment, with costs varying widely based on the features and the provider. Make sure to consider both the upfront costs and the ongoing costs, such as monthly or annual fees, maintenance costs and payment processing fees.

Remember, the most expensive system isn’t necessarily the best. It’s about finding a balance between cost and functionality.


Your EPOS system should be able to grow with your business. As your business expands, you might need additional features or the ability to handle a greater volume of transactions. Choose a system that is scalable and can adapt to your changing needs.


Most businesses use a variety of software solutions, from accounting and HR systems to customer relationship management (CRM) and ecommerce platforms. Ideally, your EPOS system should be able to integrate with these other tools to enable data sharing and streamline operations.

Purchasing vs renting an EPOS system

One crucial decision to make when choosing an EPOS system is whether to purchase or rent the equipment. Both options have their merits and drawbacks, and the right choice will depend on your business’s specific circumstances.

Purchasing an EPOS system

When you purchase an EPOS system, you pay a lump sum upfront and own the equipment outright. This option often includes the necessary hardware such as cash drawers, receipt printers, barcode scanners, and card readers, in addition to the EPOS software.


  • Lower long-term costs
  • More control over your system
  • Can be more cost-effective over time if the system has a long lifespan


  • High initial outlay
  • Responsibility for maintenance and upgrades
  • Risk of technology becoming outdated

Renting an EPOS system

Renting an EPOS system, often referred to as leasing, involves paying a regular fee to use the system. This cost is typically a monthly or annual charge and can include services such as technical support, system updates and hardware replacement in case of failure.


  • Lower upfront costs
  • Regular updates and maintenance often included
  • Flexibility to upgrade as new technology becomes available


  • Ongoing costs can add up over time
  • Less control over your system
  • Potential for long-term contracts and cancellation fees

The decision between purchasing and renting an EPOS system will depend on your business’s financial situation, your long-term plans, and your comfort level with managing the system’s maintenance and upgrades. As with any significant business decision, it’s advisable to consult with a financial advisor before deciding which option is right for your business.
