A POS system is a computer system used to manage inventory, track sales, and process transactions in a retail or hospitality setting. This type of software is extremely useful for businesses of all sizes, as it can help streamline operations and improve efficiency.

A POS system can optimize your business operations and help you save time and money. But how does a POS system work? What alternatives can you find in the market? How do you choose the best POS system for your business? In this blog post, we answer all the questions you may have regarding POS systems.

What is a POS system?

POS stands for point of sale. Businesses can track sales and manage inventory using a POS system, which combines hardware and software. You can think of a POS system as the brains behind a retail operation. It’s what tells you how much inventory you have on hand, what items are selling well (and which ones aren’t), and how much profit you’re making.

A POS system can also help streamline the checkout process for customers, making it quicker and easier for them to pay. POS systems vary in features and complexity, but all of them perform the basic functions of tracking sales and managing inventory.

Some POS systems are very simple and only include basic features like tracking sales totals and might just have a simple barcode scanner. Other POS systems are much more complex and include features like real time inventory tracking, margin analysis, customer databases, and gift card support.Depending on your needs, you might find some of them more useful than others.

How does a POS system work?

A POS system is made up of different components, including software, hardware, and peripherals. The software is the heart of the system, managing inventory and processing transactions. The hardware includes the computer equipment needed to run the software and accept payments. Peripherals are optional devices that can be added to the system to improve efficiency, such as barcode scanners and receipt printers.

Most POS systems work by tracking sales information and inventory levels in real-time. When a sale is made, the POS system updates its records to reflect the new sales totals and inventory levels. The reports that are created using this data can provide business owners with details about their sales, inventory, and profitability.

Types of POS systems

From straightforward cash registers to complete computer systems, there are numerous types of POS systems on the market. The type of system you need will depend on the size and complexity of your business operations. Small businesses can get by with a basic cash register, while larger businesses require something more advanced, like a computerized POS system.

There are two main categories of POS systems:

  • On-premise POS systems are installed on a local server or computer. This means that businesses have to maintain their own hardware and software, which can be costly. On-premise POS systems also require more technical expertise to set up and use.
  • Cloud-based POS systems are hosted by a third-party provider. This eliminates the concern that businesses have over maintaining their own hardware or software. Cloud-based POS systems are typically easier to set up and use, and they can be accessed from anywhere with an Internet connection.

What are the benefits of POS Systems?

Improved efficiency

One of the most important benefits of using a POS system is that it can help you keep track of inventory and sales so you can easily see what’s selling and what needs to be reordered. A POS system can help you be more efficient in your operations by automating some of the tasks that would otherwise be done manually. For example, if you sell products that come in different sizes and colors, a POS system can help you keep track of which version of the product is selling the most so you can adjust your inventory accordingly.

Increased profitability and sales

Utilizing a POS system also gives you the opportunity to boost your sales volume and profitability. With features like barcode scanning and customer loyalty programs, you can provide a better shopping experience for your customers, leading to increased sales. Besides this, POS systems can also help you identify potential areas of your business where you could be losing money. For example, if you sell products that have a lot of different options (like size, color, etc.), a POS system can help you see which combinations are selling the most and allow you to focus on the winning ones.

Reduced costs

By tracking inventory levels, you can avoid over ordering, which can help you save money on storage costs. This is especially important if you sell perishable goods or if you have a high inventory turnover. In addition, POS systems can also help with shrinkage (theft and loss of goods), and save time and money on administrative tasks like bookkeeping and customer support.

Better customer management

A good POS terminal allows businesses to improve customer relationship management. Retail stores often run into a lot of trouble when it comes to managing customer loyalty and gift card programs. This is because most traditional methods of managing these programs are error-prone and time-consuming. With a POS system, you can automate customer loyalty programs and gift card balances, making it easy to keep track of your loyal customers and offer them rewards.

9 benefits of updating your POS system

What to look for in a POS system

Not sure how to choose the best POS alternative? Here are some factors to consider when comparing different options.

Ease of Use

One of the most important factors to consider when choosing a POS system is ease of use. The system should be easy to set up and use so that you can get started using it as quickly as possible. Additionally, the system should be straightforward to train employees. Among many things, a good point-of-sale will allow your staff to easily generate sales reports, create promotions and process credit card payments.


Another factor to consider is functionality. The POS system should have all of the features that you need in order to run your business effectively. For example, if you are a retail business, you will need a POS system that can track inventory and sales. If you are a restaurant, you will need a POS system that can manage orders and payments from customers. Make sure to choose a POS system that has the specific features that you need.


If you want to have the best possible experience, you will need to make sure that your POS system is either compatible with your existing equipment, or upgrade to newer hardware. Additionally, you will need to make sure that the point-of-sale system is compatible with any existing software that you are using, such as QuickBooks or Microsoft Office. A good POS solution should also be also compatible with mobile devices in case you need to manage your business on the go.

Customer support

Finally, you will want to make sure that the POS system you choose comes with excellent customer support. This is important in case you have any questions or problems using the system. If possible, look for a company that offers around the clock customer support so that someone is always available to help you if needed.

Which types of hardware and software does a POS system typically include?

POS hardware typically includes things like a receipt printer, a checkout counter, and payment processing hardware and software. Besides that, modern POS systems can also include barcode scanners, customer displays, and a cash drawer. Each of these items plays a specific role when managing your sales. For example, the receipt printer is used to print receipts for customers and the checkout counter is used to total the amount of the sale and to process payments.

Other types of hardware that you might need include an electronic signature capture device, a pin pad, and a barcode label printer. On the other hand, when it comes to software, you will probably need to choose a POS system that includes features like inventory management, sales reporting, and customer loyalty programs.
