The retail industry is undergoing a massive revolution, thanks to new technologies and a spike in data analytics platforms. At the center of the retail technology environment is point of sales (POS) systems.

POS systems have evolved far beyond just the point of transaction. Today, they’re the foundation for running a successful small business.

Dick Calio, founder of R.J. Calio Consulting – a full-service consultancy specializing in retail technology strategy – regularly performs POS implementations for retail chains. He typically focuses on retailers with 30-35 stores or more.

“The retail industry is undergoing a dramatic disruption,” Calio said. “They’re focused on how to keep the customers engaged. Customers want to buy whenever, however, and wherever they want. Retailers now need to engage on customers’ terms.”

What is a POS system?

POS refers to the point where a purchase is made and the payment is accepted. In the old days, this was just a cash register, but modern POS systems are a combination of internet-connected hardware and software that performs these tasks:

  • Stores information about each product or service, including price
  • Allows the cashier to select items being purchased by searching on a screen or using a barcode scanner
  • Adds up the purchase amount, calculates sales tax and any shipping charges
  • Gives cashiers the ability to apply discounts via coupons, coupon codes or manager overrides
  • Keeps customer data and purchase history
  • Updates the inventory to account for purchased or returned items
  • Accepts payment directly or through an attached credit card reader
  • Creates cash flow statements and reports on sales, inventory and employee productivity 
  • Allows business owners to schedule employees
  • Sends orders to appropriate stations in a kitchen and optimizes a restaurant’s seating capability

Must-have features in retail POS system

Integration is critical for POS systems, Calio said. Retailers need a reliable POS system that easily integrates with third-party applications. POS is only as good as the other applications it interacts with; it’s just one piece within your shopper engagement toolkit.

“Thirty-five years ago, POS systems used to be just that: point of sale,” Calio said. “But now it’s the hub of a store’s entire IT infrastructure. And its main goal now is to drive shopper engagement.”

These are some of the top features to consider when evaluating retail POS systems:

  • E-commerce capability: Look for a system that can support and integrate with other technologies, giving you complete control over how to display, manage and customize your online presence.
  • Warehouse management: This feature is critical to streamlining your operations (and reducing headaches), including tracking inventory and stock locations. This is your key to moving faster and working smarter.
  • Omnichannel experience: Retailers no longer have the luxury of operating in silos. Customers want an omnichannel experience. The right POS system can help you achieve that by providing insights into the entire customer buying journey – no matter where or how they like to shop. This includes customer experiences, such as: “buy online, pick up in-store,” “buy online, ship from store,” and “buy in-store, return to another store.”
  • Open API: An open API gives you increased flexibility, with benefits like easy integration with third-party systems and easy access to data.
  • SaaS-based programs: Software as a service (SaaS) gives you the software, support and upgrades in one monthly fee. It also eliminates hurdles retailers previously faced with credit card compliance and security.

Benefits of a retail POS system

When you integrate a retail POS system, your business gains these advantages:

  • Efficiency: According to Expert Market’s website, the most obvious benefit of a retail POS system is efficiency. POS systems are easy for employees to use and offer a much smaller margin for human error. Increasing efficiency can make employees happier, which will, in turn, make customers happy.
  • Stock management: POS inventory management features are essential for a retail business. Traditionally, a company would have to conduct a physical inventory. POS systems allow retailers to view their inventory at any time. Many POS systems also provide low stock alerts. This can be invaluable for businesses that rely heavily on inventory.
  • Digital product database: For companies with more than one retail location, a digital product database allows prices to be set consistently from store to store. Sales and special discounts are much easier to manage because they go into effect at all stores simultaneously.
  • Consistency: Consistency is an essential aspect of customer satisfaction and customer loyalty. Today’s customers generally expect to find consistency between online and in-store pricing, and pricing from one store to another.
  • Employee tracking: POS systems allow for easy employee tracking. You can view sales figures for individual employees and any mistakes that need correcting. This makes it easy to provide incentives for top-performing employees, which fosters healthy competition.

Other POS system features allow you to provide extra training or reevaluate employees who are performing below average. They can also give you the information you need to decide the best employees to staff at the busiest times.

Retail POS system costs

There are three components to a POS system: hardware, software and payment processing. Many components are compatible, allowing you to choose the hardware, software and payment processor that gives you the best deal.

  • Hardware: The cost of a card reader ranges from $20 to $100. If you need a mobile device to run the software, factor in those costs. Most small businesses choose basic peripherals, including a tablet stand, cash drawer, card reader and receipt printer. This kind of setup costs $600 to $1,000.
  • POS software: Payment processors – like PayPal – offer basic POS systems when you select them as your payment processor. For example, Lightspeed costs $69 a month for the basic plan and $229 a month for the pro plan, which is billed annually. It also offers a 14-day free trial.
  • Payment processing: Credit card processing rates vary. Some systems offer you the choice of using a third-party processor or their in-house processor. This gives you more flexibility.
