What does POS stand for?

POS stands for Point of Sale, which refers to the physical location of a transaction between a merchant and a customer. This includes hardware such as a cash register, receipt printer, credit card reader, and barcode scanner, as well as software for payment processing, employee management, inventory management, and reporting.

How does a POS system work?

A POS system connects hardware (such as a register, credit card reader, cash drawer, receipt printer, and barcode scanner) with software to process payments, manage inventory, track sales, and analyze customer behavior in real-time. When a customer makes a purchase, the POS system processes the transaction data. The system calculates the total amount due, applies for relevant discounts or promotions, and handles various payment methods, such as cash, credit cards, or digital wallets. 

Additionally, a POS system updates the inventory in real-time, deducting sold items from the available stock. This feature ensures accurate stock management and helps merchants avoid stock-outs or overstocking. Furthermore, a POS system can generate detailed reports on sales, inventory levels, and customer behaviors, providing valuable insights for business analysis and decision-making.

What are the benefits of POS systems?

A robust POS system can revolutionize businesses’ operations and contribute to their success. Let’s explore the key benefits of POS systems in detail:

Payment processing

A POS system enables businesses to accept various payment methods, including credit cards, debit cards, mobile payments, and cash. Depending on the integrations, merchants can process transactions quickly and securely, reducing checkout times and enhancing the overall customer experience.

Staff management

A POS system provides features for employee management, such as:

  • Monitoring working hours
  • Tracking sale figures per employee & time slot

With these features, merchants can streamline their staffing processes, track employee performance, and make data-driven decisions to improve operational efficiency. This benefit of POS system is beneficial for retail or hospitality industries.

Inventory management

A POS system offers robust inventory management capabilities, avoiding stock-outs, minimizing overstocking, and optimizing inventory turnover. It allows retail business owners to track stock levels and gain real-time visibility into their inventory. Every transaction updates the inventory by deducting the items sold immediately, allowing for exact store stock quantities monitoring.

Furthermore, the POS system can keep a record of the best-selling items and automatically restock them when the inventory runs low. 

Customer satisfaction & loyalty

A POS system allows business owners to store customer data, including purchase history and preferences, enabling personalized interactions and targeted marketing campaigns. This ensures customer satisfaction and loyalty boosts their propensity to revisit the store.

Online Order Management

The POS system with integrated online order management capabilities ensures seamless order processing across multiple channels. It enables business operators to synchronize inventory levels between online and offline stores, track online orders, and manage fulfillment efficiently.

Reporting & analysis 

Data-driven decision-making is essential for business growth and success. Instead of creating manual reports, a POS system provides comprehensive reporting and analysis tools, allowing business retailers to gain valuable insights into their operations. Automated reports show various aspects of the business, such as sales, pricing, purchases, contact, and inventories.

These insights enable merchants to identify strengths, weaknesses, and opportunities, optimize strategies, and make data-backed decisions to drive profitability and growth.  

Which hardware and software does a POS system typically include?

A POS system integrates hardware and software components, functioning harmoniously to streamline multiple business operations.

POS Hardware 

POS hardware refers to the physical devices and equipment that enable merchants to accept payments and perform other essential tasks. Here are some commonly used POS hardware components: 

  • Register: A register assists in accurately calculating and efficiently handling customer transactions. Without it, the store may seem outdated and unprepared to handle transactions efficiently.
  • Credit card reader: A device that reads and processes credit and debit card information, allowing business operators to accept card payments securely. 
  • Cash drawer: A secure compartment stores cash received from customer transactions. Connecting Point of Sale (POS) software to a cash drawer helps reduce the risk of fraud by systematically recording every instance of drawer access. This enhances transparency, lowers the potential for unauthorized transactions, and promotes a more secure transaction. 
  • Receipt printer: A printer generates receipts for customers after a transaction is completed, providing them with a record of the purchase.
  • Barcode scanner: A device scans product barcodes for quick and accurate product details, enabling efficient inventory management and faster checkout.

POS Software

POS software is the digital component of a POS system that controls and manages the operations and functionalities. Here are some key features typically found in POS software:

  • Payment processing: POS software integrates with payment gateways and enables wholesalers to process various payment methods, including Cash, Secure Online Payments, Magstripe Credit Cards, Chip Cards, and Contactless Payments.
  • Employee management: POS software allows business owners to manage employee profiles, track hours worked, assign roles and permissions, and generate reports for better workforce management. 
  • Inventory management: POS software provides tools to track and manage product levels and ensure efficient inventory control. Automatic inventory software links up with your sales data and alerts merchants when a product runs low in stock.
  • POS reports: The software generates detailed reports on sales performance, inventory status, employee productivity, and other vital metrics, helping business owners gain insights and make data-driven decisions.

How much does a POS system cost? 

A POS system cost varies and hinges on several factors, including business types and desired features and functionalities ranging from $3.000 to $10.000

POS software cost

The price of POS software can vary depending on various factors, such as the system’s complexity, the number of features included, and the provider’s pricing structure.

  • Cloud-based POS software: This type of software operates on the Software-as-a-Service (SaaS) model and is hosted in the cloud
  • Legacy or on-premise POS systems: These systems are hosted on a local server or operated on-premise.
  • Hybrid POS systems: A solution that combines cloud-based and on-premise functionalities.

It’s essential to consider both the short-term and long-term expenses associated with POS software, including hardware costs, installation fees, ongoing support charges, and additional modules or add-ons. By carefully assessing your business needs and evaluating different providers, you can make an informed decision that aligns with your budget and requirements.

Real-world examples or case studies of businesses benefitting from Shopify POS

Shopify POS has empowered numerous enterprises to streamline their operations and achieve success. Here are a few real-world examples: 

Switching to Shopify POS results in a 20% growth in Tigerlily’s store average order value.

Tigerlily is a premium swimwear brand in Australia that operates both online and in 11 brick-and-mortar stores. Despite recognizing the importance of serving customers, Tigerlily faced a challenge in creating a consistent customer experience across its online and physical store sales channels.

To address this issue, the company switched to Shopify POS to unify its sales channels and support hybrid shopping options. Since implementing Shopify POS, Tigerlily has experienced a 20% growth in store average order value and 20% rise in group revenue in FY23 compared to FY22. 

Additionally, multichannel shoppers have shown higher average order value than single-channel shoppers by 4%. With detailed reports and centralized reporting, Tigerlily can offer more personalized recommendations to shoppers and increase revenue.

Since switching to Shopify POS and bringing our sales channels together, we’ve seen a 20% growth in store average order values and year-over. Customers appreciate that our experience online and offline feels consistent, which helps drive more sales” – Travis Wright, CEO, Tigerlily
