Retail businesses rely on their point-of-sale (POS) system to keep their businesses running smoothly. Customer management, inventory control, payment processing, and employee management—retail POS systems need to cover a lot of ground. To help you find the best POS system for your retail business, we reviewed the top retail POS systems on the market and, using our expert analysis and in-depth evaluation, narrowed them down to the top five options. 

Based on our findings, the top five retail POS systems are:

In this guide, we will examine each of the top POS systems, reviewing and comparing them based on their strengths, weaknesses, best applications, pricing, and key features.   

  • March 11, 2024: Complete rewrite of full buyer’s guide with new vendors and the addition of rubric scoring.

At TechnologyAdvice, we assess a wide range of factors before selecting our top choices for a given category. To make our selections, we rely on our extensive research, product information, vendor websites, competitor research, and first-hand experience. We then consider what makes a solution best for customer-specific needs. 

By defining business needs, we can determine the essential features organizations in various sectors require, and select platforms that will cover all bases. Reputable providers known for their ease of use and customer satisfaction are added to our compilation list for further analysis. We then evaluate each solution on the list based on the features they offer, considering the platform’s usability, integration capabilities, customization options, mobile access, and any other relevant functionalities.

Price plans, hidden fees, customer reviews, and customer support are also assessed in the selection process. TechnologyAdvice writers will often take advantage of free trials and demos to get a first-hand user experience of available software. Finally, we curate a comprehensive list based on the previously stated factors, ensuring readers have the necessary tools to make an informed decision.

We rely on an internal algorithm to calculate star ratings, which are based on many factors.  

My research focused on your top-of-mind concerns like price, core features, user experience, and security. Each category also includes my expert score, which contributes to its overall score.

​​As the market changes, we reevaluate our choices so you always receive the best insight for your purchasing decision.

User reviews from third-party software platforms like Capterra and G2 accounted for a small portion of the software’s overall score. I focused on software that received at least 3.5 out of 5 stars on these sites. Because users have real-world experience with each platform, they played a significant role in narrowing down my list of top products to compare.

Pricing: 

Software with transparent pricing, affordable subscriptions, no fees for additional registers, and integrated payment processing received the highest scores. I also considered each platform’s “value for money,” which determines whether the number of features in each price tier or module is competitive with other vendors in the space.

Platform and interface: 

How easy is the platform to use? Will it be able to grow with me? What is the customer service like? And will employees’ data be safe? This category covers the intrinsic features of most software platforms and vendors, including how well they will integrate with your current tech stack. 

Hardware and basic functions: 

We prioritize systems that can work on any hardware, especially low-cost options like iPad. We also consider durability and market-specific hardware options for each vendor. Scanner and scale tools, checkout options, and employee management capabilities are also major decision-making factors. Finally, we consider if the POS system offers a customer-facing display, as the best displays let customers enter loyalty information and payment options.  

Help and ease of use:

Because business owners need to spend the most time attending to customer needs instead of handling tech issues, we prioritize customer support and ease of use. In retail, restaurant, grocery, or any other spaces in which POS systems are used, problems must be fixed in real time. Our scores in this category center around customer support hours, level of support at each price tier, intuitiveness of the interface, and ease of integration with non-native apps.

Shopify includes sales channels for your online store, Instagram, Facebook, TikTok, eBay, Google, Amazon, and more. Simply add the sales channels you want to track and Shopify will take care of the rest. 
  • Online store: Every POS account comes with a very basic online store builder where you can create your ecommerce shop. In addition to the ecommerce store that comes as part of your POS account, you can also upgrade to one of Shopify’s ecommerce plans for access to the best ecommerce platform in the game that will seamlessly pair with your POS.  
  • Shopify app store: You can integrate hundreds of third-party tools to your Shopify POS for things like loyalty programs, inventory management, outreach marketing, analytics, and more via the Shopify app store. Note, however, that many of these tools come with their own monthly fee.

Along with its two software plans, Shopify also offers a number of hardware options for both in-store and mobile operations.

Shopify’s hardware options include: 

Shopify POS is a top choice for retail businesses that focus more on ecommerce, social, and marketplace selling but still need a POS system to support in-person sales. The Shopify POS system has everything you need to complete transactions, keep track of your customers, manage your inventory, and take your business on the go. 

What makes Shopify stand out from the rest is its omnichannel selling tools. No other POS system on the market has so many sales channel integrations, meaning you can sell your products practically anywhere, and Shopify will track your sales and inventory on one platform. The Shopify app store also has hundreds of add-ons that seamlessly integrate with your POS, so you can customize your toolkit based on your unique business needs.

Shopify’s POS comes with all the tools you need to manage your in-store operations along with an ecommerce site builder. You do, however, have the option to upgrade your POS or ecommerce plans to more advanced versions. Shopify’s greatest strength is its tools for unifying in-store with online, perfect for sellers looking to sell across multiple channels.

  • Reporting: PayPal Zettle will generate reports on your sales, products, and inventory segments.  
  • PayPal integration: Because the system is part of the PayPal ecosystem, PayPal is integrated into your checkout page. This means that customers can pay through PayPal, giving them access to PayPal’s financing options like pay-in-four and PayPal Credit.

PayPal Zettle, formerly iZettle, is PayPal’s free POS system. Like Square, PayPal Zettle only charges transaction fees with no monthly software fees. The POS system has all the basic features a small retailer needs to complete sales, track inventory, manage customers, and take their business on the go. Additionally, because the system is tied to PayPal, the processing rates are extremely low—perfect if you need to keep expenses down. 

The biggest drawback of using Zettle is that there are no additional plans or features to support you as you grow. This means that if you outgrow the basic functionality of your Zettle POS system, you will have to look to a different POS provider. Additionally, there is limited ecommerce and no social media or marketplace integrations.

  • Reporting: Clover generates real-time sales reports, sales reports that look at product performances and sales over time at a granular level, along with tax reports. 
  • Ecommerce: Clover offers an ecommerce platform for an additional fee, but also integrates with existing online stores so you can track your online and in-person sales all from one place. 
  • Payment processing: Clover offers payment processing via Clover Payments or you can configure your system to use any other payment processor of your choice. Be warned, however, once your POS is set up with one merchant, you cannot change to another. 
  • Customer management: Create customer profiles that store contact information and purchase histories, store them in your customer database, and learn more about your shoppers with customer reporting.  
  • Promotional and marketing tools: Create promotions, use Clover’s free included loyalty program to drive repeat visits, offer both physical and digital gift cards to shoppers, and promote user reviews with review prompts that are built into your digital receipts. 
  • Employee management: Create individual log-ins and permissions and manage your employees’ shifts. Note that there are no permissions or access controls. 
  • Rapid deposits: For an additional 1.5% processing fee, you can receive rapid deposits, meaning you can get your money within minutes of any credit card sale.

Clover’s Retail System consists of three plans that vary based on both the tools and hardware included. These plans are priced monthly, with one rate based on if you are paying for your hardware as part of your monthly fee and another for if you paid for your hardware outright and are only paying for the software. These plans are priced as follows: 

  • Starter: $60/month for 36 months or $799+ $14.95/month
  • Standard: $135/month for 36 months or $1,799+ $49.95/month

Clover is unique for two reasons. First, unlike the other options on our list, Clover’s plans include both software and hardware. And second, Clover does not require you to use an in-house payment processor and will let you integrate any third-party merchant account for no additional charge. This makes Clover ideal for businesses that want to take care of their hardware and software needs with a single plan, or for businesses that could benefit from being able to choose their own payment processor. 

Clover is also unique because it offers a free loyalty program and more advanced promotional tools in all of its plans. However, you might look to a different option, like Shopify, if you are most focused on online sales, as Clover is best suited for primarily brick-and-mortar retailers.

Clover does, however, offer its own processing, Clover Payments, if you want to go with an in-house option. Clover is also unique because, when you sign up, you not only are signing up for POS software, but you will also need to get Clover’s proprietary hardware. This means you won’t need to shop around or run the system from your personal devices—everything is included in your Clover plan.

Key components of POS systems for retail

When you are looking for a POS system for your retail business, below are the tools you should look for. While you might not need all these tools now, the POS provider you choose should offer them for you to consider as you grow.

  • Payment processing: Some providers require you to use an in-house payment processor, and others allow (or require) you to use a third-party merchant instead. Consider which option is better for you. High-volume businesses typically get better value when they can choose their own merchant account. 
  • Hardware: The best POS systems for retail offer hardware for in-store and on-the-go sales that you can pay for via monthly financing so you don’t run yourself dry before ever making a sale. 
  • Mobile compatibility: To ensure you can complete sales anywhere, your POS should be mobile compatible.
  • Inventory management tools: Your POS should have tools for placing and tracking orders, adding inventory to your catalog, and integrated tracking as products sell across all locations and channels. Additionally, you should be able to view inventory reports and analyses.  
  • Reporting: Retail POS systems should offer reports on your inventory, staff performance, marketing initiatives, customer relationships, and your sales channels. The best systems will also offer custom reporting options and actionable analyses of your performance.  
  • Customer relationship management tools: Your retail POS system should have tools for creating customer profiles that log their purchases, contact information, and relevant notes. The best systems will also include tools like loyalty programs and customer segmentation reports.  
  • Marketing features: Marketing tools for sending texts and emails should be integrated into your retail POS. Additionally, more advanced systems will have tools for measuring the success of your marketing campaigns and suggestions for how to improve. 
  • Multilocation management: Your retail POS system needs to be able to track inventory and sales across multiple locations and create reports for both cumulative performance and individual stores and sales channels. 
  • Omnichannel sales: Along with managing multiple store locations, your retail POS system should also be able to manage all your additional sales channels, including your online store, any social media shops, and marketplaces like Amazon and Google Shop. 
  • Integration options: If you have an existing online store or particular tools that you want to be able to use alongside your POS system, be sure they integrate or there is a custom API option so you can keep all your tools on one platform.

FAQs

While it is not impossible to run your retail business without a POS system, it is certainly 100 times more challenging. POS systems streamline your operations, allowing you to complete sales, track inventory, and manage your staff and customers all from one place.

While there are a number of top-notch options available for free, like Square and PayPal Zettle, most larger retail businesses can expect to pay $60–$200 per month per register. However, the cost is well-worth the saved time and expenses in your business operations.
