But what exactly is a POS system and how do you select the right solution for your business?

To answer that question, we’ve put together a guide on all things point-of-sale. Below, you’ll learn why POS systems are essential, what features to look for in a solution, and the top POS software in the market.

Let’s get started.

What is a POS system?

A POS system is a solution that facilitates in-person transactions by enabling merchants to ring up sales.

But that’s just the tip of the iceberg.

Today, POS systems go beyond simple sales processing capabilities. Most modern POS solutions are designed with advanced features such as:

  • E-commerce integration capabilities
  • Contactless payment options
  • Mobile POS abilities
  • Reporting and analytics

For many users, the POS is the central hub for their business operations. Everything is tracked and monitored, including customer management, payment processing, and inventory management. As such, merchants are increasingly using POS software to run their businesses. So much so that the POS software market is expected to hit $18.1 billion by the year 2027.

What Merchants Should Look For In A Merchant Pos System

What is a POS system used for?

As a small business owner, you are probably used to doing everything yourself. However, wearing the hat of CEO, marketing manager, accountant, and all these other roles can become overwhelming.

With overwork being the most common cause of burnout for business owners, now is the time to learn how to work smarter, not harder. A POS system offers a great stepping-stone for this quest.

With the right POS system, you can streamline or automate many tasks, including:

Ringing up sales

The primary function of a POS system is to ring up sales. As such, point-of-sale solutions typically come with a sales screen or monitor where cashiers can add products to the sale.

In addition, POS systems often connect with your payment processor, allowing you to accept credit cards, and other methods (e.g., contactless and mobile payments).

Inventory management

Most modern POS systems can also track and record inventory movements. So whenever you make a sale, the system updates your stock levels accordingly.

You can easily monitor things like restocking, returns, and sales with the right POS technology.

Tracking business financials

Modern POS systems can integrate with existing accounting systems. Thanks to this capability, your tax preparation needs are simplified significantly.

Reporting and analytics

Many point-of-sale systems also come with reporting and analytics capabilities so you can track your sales, product performance, top customers, and more.

All that data can then be used to make more informed decisions in your business.

Supervising employees

Many POS systems have employee management capabilities, enabling you to monitor sales per employee, staff activity, and more.

The types of businesses that use POS systems

Point of sale systems are seen throughout multiple industries. Chances are, if you own a business, you have probably used this type of system at one point or another. Some of the industries that use POS systems include:


POS systems are a staple at retail stores that sell physical goods. Below are a few examples of the types of business that benefit most from point-of-sale solutions:

  • Clothing and shoes
  • Electronics
  • Food
  • Pet supplies
  • Entertainment
  • Beauty supplies
  • Alcohol
  • Tools
  • Home goods


You will likely interact with a POS system when you go to a restaurant or stay at a hotel. Some of the other businesses in the hospitality industry that utilize a POS include:

  • Restaurants
  • Bakeries
  • Travel agencies
  • Coffee shops
  • Flight attendants
  • Wedding services
  • Chauffeurs and drivers
  • Housekeeping
  • Valets

Consumer services

Consumer services include any situation where you receive a service instead of a physical product. For example, you have received consumer service if you get your car washed or your hair and nails done.

Some other businesses that fall into this category include:

  • Salons and barbershops
  • Spas
  • Therapists

What should merchants look for in a POS system?

As you can see, POS systems are used in multiple industries and offer many benefits. Now that you know how beneficial it can be, it is time to explore what type of POS solution your business needs. Some factors to consider when evaluating a POS system include the following.

Ease of use

Setting up a POS system should not require an engineering degree. Instead, you should find one that is user-friendly. The system also needs to be easy enough to use that you don’t have to constantly refer to your manual or call for help from tech support constantly.

Integrated payment processing

Finding a POS system that provides integrated payment processing will help you streamline all payment transactions. That’s because the payment processor and POS system will exchange all needed data automatically.

If you don’t have a system with payment processing, you have to enter customer debit card and credit card information manually. That means each time a sale is made, you have to spend more time keying in the information, which then opens up room for human error.

Hardware considerations

The type and size of your business will dictate the type of hardware needed. Your checkout process also impacts your needs. Having a cash drawer, credit card reader, and iPad or Android tablet is beneficial if you have a small retail business.

More advanced equipment is available for larger operations, including barcode scanners, receipt printers, and terminals.

Inventory management capabilities

A small business owner may think they don’t need this feature. This is especially true if the retailer doesn’t carry many different items. However, it’s worth noting that inventory management is more than knowing how much stock you have on-site.

With this feature, you can track your inventory in real-time and avoid manually counting every item. It can also send you notifications or alerts if stock levels are too low and provide inventory reports. This will help you identify the extremely popular products and those that aren’t as popular.

Choosing a POS system with inventory management will help you plan and ensure you stay stocked in the products your customers order most.

PCI compliance

Payment security is a must-have feature. This is particularly the case for smaller businesses because these entities are victims of almost 43% of all cyberattacks.

All POS systems should comply with all data security standards set by the PCI (Payment Card Industry). It’s also wise to find a solution that will help you further safeguard customer’s payment information. Some of the features that make this possible include:

  • Data tokenization
  • End-to-end encryption

Employee management

POS systems featuring employee management capabilities can help you manage your staff each day and help you save money and time. With this functionality, your employees can clock in and out using the system. If you choose a more robust system, you can set limits that prohibit employees from clocking out before inputting their tip amount for their shift.

It’s also possible to set permissions based on different worker’s seniority and role in the company. This ensures employees can access the features they need and nothing else in the system.

You can also find systems that will split, pool, and track tips among servers. This eliminates having to handle this task manually.

Customer support

It doesn’t matter how tech-savvy you are. Having access to a POS system’s customer support team is invaluable.
Even if you don’t run into issues as you set up the system, it is still wise to choose a POS system that offers 24/7 support. This support may be offered via phone, email, or live chat.


The cost of the POS system is a factor that most businesses must consider. Most POS systems these days charge monthly or annual subscription fees, based on factors like number of users or outlets, size of your catalog, types of features, and more.
