What is a POS system?

A POS system, short for point-of-sale, is a tool businesses use for in-person sales, including devices, software, and payment services. It handles customer purchases, accepts payments, and issues receipts.

Modern POS systems go beyond traditional cash registers. They can generate reports, assist with inventory management, and track employee hours, offering a range of functionalities for businesses.

Key components of a POS system include:


  • Cash Register/Drawer: A safe place to store cash and coins.
  • Barcode Scanner: Quickly input item info by scanning product barcodes.
  • Credit Card Terminal: This lets businesses accept credit and debit card payments.
  • Touchscreen Monitor/Computer: Use it to run the POS software and enter transaction details.
  • Customer Display: A handy tool for showing customers their items and prices.
  • POS Terminal: The central unit that links all hardware and runs the POS software.


  • Point of Sale Software: This is the primary tool for handling sales, managing inventory, and creating reports.
  • Payment Processing Software: This software handles electronic payments and works with the POS system.
  • Inventory Management Software: Keep track of your stock levels, reorder when needed, and manage product information quickly.
  • Employee Management Software: Control user access, monitor employee sales, and keep an eye on work hours efficiently.
  • Reporting and Analytics: Get reports on sales, inventory, and other essential business metrics for better analysis.
  • Customer Relationship Management (CRM): It’s optional but handy for keeping tabs on customer data and preferences.
  • Cloud-based Functionality: While not necessary, it’s becoming more common. It allows businesses to access and manage their POS system remotely.

Understanding how a POS system works

A POS system helps your business take payments and manage sales. Simply put, it adds up what a customer wants to buy, handles the payment, and updates your inventory. 

Usually, the system works like this:

A flowchart showcasing the 4 steps on how a POS System works.

1. The customer makes a purchase

Customers choose what they want and then go to the checkout counter. At the counter, either the cashier or the customer uses a barcode scanner to scan the product barcodes. If no barcodes are available for an item, it can still be added to the system by manually entering its details.

2. The system calculates the total

When you scan or input items, the POS system instantly calculates the total cost by adding up their prices. It also considers taxes, discounts, or promotions that might change the final amount.

3. The customer makes the payment

The customer then provides payment for the total amount. Payment can be made using various methods such as cash, credit/debit cards, mobile payments, or other electronic forms of payment such as loyalty points or gift cards.

If the payment is made by card, the system may prompt the customer to insert, swipe, or tap their card on a card reader to complete the transaction.

4. POS transaction is finalized

When the payment goes through, the POS system completes the transaction. It gives your customer a receipt with all the details about what they bought, the total cost, and any change they might get.

It also keeps track of inventory, sales reports, and other vital information to help your business run smoothly.

Why should you use a POS System?

Improves operational efficiency

Joy Baer’s research in “The Time to Win” reveals that 50% of customers won’t wait more than three minutes in a store. Customers are willing to pay 19% more for “always immediate service,” emphasizing the importance of speed and convenience.

Point of Sale (POS) systems are vital in speeding up checkouts, ensuring faster and more efficient transactions. In retail stores and restaurants, where customer satisfaction is critical, quick and accurate transactions contribute significantly to customer happiness.

Expands your payment capabilities

Digital payments are on the rise globally, with two-thirds of adults using them, particularly in developing economies where the share has grown from 35% in 2014 to 57% in 2021, according to World Bank Group data.

Modern POS systems support diverse payment methods, expanding your customer base and boosting sales opportunities. Efficient and secure payment processing minimizes errors for a seamless transaction experience.

Improves sales reporting and analytics

BCG states that companies excelling in personalization experience better marketing efficiency, increased digital sales, and enduring customer relationships, resulting in growth rates rising by 6% to 10%.

POS systems generate detailed sales reports and analytics, providing crucial insights for business owners. This information aids in making informed decisions, such as identifying popular products, peak sales times, and customer buying habits, ultimately helping optimize business operations and enhance profitability.

Better employee management

A study found that U.S. employers lose over $400 billion yearly due to decreased productivity. Even small breaks of 10 or 15 minutes may not seem like much, but they add to significant losses over time.

POS systems can help track employee performance by keeping an eye on sales productivity and identifying top-performing staff. Features like employee logins enhance accountability, preventing unauthorized transactions and making the work environment more secure and trustworthy.

Enhances your security

Handling cash for businesses means keeping it safe, secure, and accounted for, which can be tricky due to transportation and security issues. Small businesses in less advantaged areas, without access to advanced security or cash transport services, bear a higher burden as cash theft amounts to approximately $40 billion annually in the U.S. retail sector.

POS systems enhance security through encrypted transactions and user authentication, minimizing the risk of fraud. Centralizing transaction data helps businesses safeguard sensitive information, ensuring compliance with industry standards and regulations.

Choosing a POS system for your business 

Flowchart showcasing the steps when considering getting a POS System for your business

1. Identify your business needs

Understand your business needs by looking at what you sell, who you sell to, and how much you sell. Decide if you need the basics, like keeping track of inventory, sales reports, and managing customer relationships, or more advanced features like connecting to online stores.

2. Understand your budget constraints

Set a budget for your POS system, factoring in initial setup costs and ongoing expenses like subscriptions, transactions, and support. Make sure to compare pricing models to find the best match for your budget, which includes one-time purchases, subscriptions, or per-transaction options.

3. Consider ease of use and training

Select a POS system that’s easy for your staff to use, reducing the need for extensive training. An intuitive interface with features like touchscreen functionality and customization options can minimize errors and enhance efficiency.

Check if the vendor provides thorough training resources, like tutorials and documentation, if training is required. Well-trained staff will facilitate a smoother transition to the new POS system.

4. Check for compatibility

Make sure the POS system easily works with your current tech setup. Check if it’s compatible with your accounting software, e-commerce platform, and other essential tools. 

Integration can make things smoother, cut down on manual data entry, and give you a better overall picture of how your business is doing.

5. Consider scalability of your business

Choose a POS system that can adapt as your business grows. Think about your future needs, expansion goals, and evolving technology. This way, your investment in a POS system becomes a lasting solution, not just a quick fix. 

6. Read reviews and get recommendations

Explore customer reviews and testimonials for firsthand insights into how businesses like yours experience the POS system. Request references from the POS provider. The vendor can assist you in selecting appropriate software with expert advice.

Additionally, read reviews from your industry peers and seek recommendations from business networks or associations to evaluate the performance, reliability, and customer support of various POS solutions.

7. Trial the system

Explore free trials or demos from POS providers to test if their system aligns with your needs and integrates smoothly with your business. This hands-on experience helps you make an informed decision before making a full purchase.
