What Is a Point of Sale (POS)?
The Point of Sale – or POS – is more than just the place where a product is sold. It is the decisive interface between customer and product, between supply and demand. In brick-and-mortar retail, the POS marks the point where a customer decides to purchase. In the digital world, it is the user interface in an online shop or app where the purchase is completed. For retailers, the POS is a strategic lever to create purchase incentives, shape experiences and build customer loyalty. This guide explains what the term means, the role of the POS in modern retail, and how it can be used effectively for sales promotion.

1. What is a Point of Sale (POS)?
The Point of Sale (POS) is the place where a transaction is completed from the retailer’s perspective. It’s where the product is paid for – at the checkout counter, via a self-checkout terminal or through a mobile device.
From the customer’s perspective, the term Point of Purchase (POP) is often used. This is the place where the purchase decision is made. While POS and POP often overlap spatially, they serve different purposes: POP initiates the buying impulse, POS completes the transaction.
2. Functions and Components of a POS
A modern POS combines systems, technologies and touchpoints with one goal: to enable fast, seamless and service-oriented transactions.
Hardware:
- Touch-enabled checkout terminals
- Scanners, receipt printers, customer displays
- Mobile sales devices, self-checkout stations
- Complementary tech like RFID, IoT buttons or sensors
Software:
- POS software with ERP or merchandise system integration
- CRM systems for customer retention
- Digital signage to communicate offers in real time
- Omnichannel functionality like Click & Collect or Order-in-Store
All components work together to provide a consistent, efficient and convenient customer experience – both online and in-store.

3. Sales Promotion at the Point of Sale
The POS is one of the most powerful places for effective sales promotion. It is where buying decisions are influenced, product preferences shaped and brand visibility increased.
Typical sales promotion measures at the POS:
Traditional physical measures:
- Secondary product placements and promotional displays
- Shelf talkers, ceiling danglers, wobblers, floor stands
- Tastings, sampling, product trials
- Promoters and trained advisors on-site
- In-store raffles, giveaways and printed coupons
- Discount campaigns and couponing, e.g. through printed vouchers or discount stamps
Digital and interactive measures:
- Digital screens showing promotions, videos or service info
- Touch-enabled displays with product detail access
- Lift & Learn technology triggering content when products are picked up
- QR codes or NFC tags linking to additional info or webshops
- Time- and location-specific content for targeted messaging
- Integrated apps or customer cards that can be activated at terminals or mobile devices
The combination of analog and digital tools creates an experience that informs, engages and converts.
4. Can a Point of Sale Be Online?
A POS doesn’t need to be physical. In the digital realm, any platform where a transaction takes place is considered a POS. Online stores, shopping apps and social commerce all fulfill this role. What matters is not the location, but the function: completing a purchase.
Examples of online POS:
- Checkout processes in webshops
- Purchase flows in shopping apps
- “Buy now” buttons on social media platforms
Retailer challenge:
The digital POS presents retailers with the challenge of creating seamless, cross-channel customer experiences. This requires merging touchpoints across systems, maintaining consistent data and rethinking internal workflows across sales and marketing. A solid system architecture and integrated strategy are critical to success.
5. The Importance of the POS in Modern Retail
The POS is the final and often most decisive customer touchpoint. A well-designed POS not only increases conversion rates but also enhances satisfaction and brand perception.
Key aspects:
- Customers expect smooth, intuitive processes
- POS design influences dwell time and purchasing behavior
- POS data delivers insights for marketing, assortment and operations
- Efficient POS systems reduce errors, streamline workflows and support staff
In practice, the POS is not just the end of the customer journey – it can also be the beginning of long-term relationships.

6. Conclusion
The Point of Sale is more than a checkout point. It’s the bridge between product and customer, between brand and experience. Businesses that actively shape their POS strategy and connect it with digital technologies strengthen their position in a competitive retail environment.
