The benefits of PoS systems

With PoS solutions, retailers can increase their operational efficiency, improve customer experiences, and reach high servicing standards.

For retailers

All-in-one system

PoS software allows for managing sales, customers, and inventory from a single place.

Streamlined operations

PoS systems smoothly connect different aspects of retail operations, making transaction, stock, customer, and staff management easier.

Valuable insights

With PoS reports, retailers can track diverse business metrics, identify customer behavior trends, and evaluate staff’s performance.

Better customer service

By automating processes, PoS systems help in-store staff focus on communicating with consumers and doing their job more accurately instead of dealing with routine tasks.

Improved inventory management

Businesses can track their inventory in real-time and know when to replenish the stock.

For customers

Flexible payment options

Modern PoS software supports various payment methods, so customers can choose the option they prefer.

Faster checkout

With integrated barcode scanners, card swipers, and printers, a PoS system allows customers to process a transaction faster and easier.

Personalized experiences

By scanning their loyalty cards at the PoS system, customers can get personalized promotions and bonuses on special occasions like birthdays.

Easy item lookup

PoS systems enable customers to check an item's availability or location in real-time, making shopping easier.

Convenient self-service

Using self-service PoS kiosks, customers can make an order and check out without a cashier’s assistance, which saves time.

FAQ about PoS systems

What is the difference between a PoS system and a cash register?

Retailers use both cash registers and point-of-sale systems to process payments. Cash registers can only process payments, calculate taxes, and print receipts, while PoS systems streamline retail business transactions and operations using more advanced functionality like inventory management, employee management, and reporting.

How do I know if I need a PoS system?

Every retailer that sells goods or services in person needs a PoS system to accept and process payments, regardless the size of the company. However, the type of PoS solution and its final feature set will vary for different industries and businesses.

What problems can retailers have with PoS systems and how to solve them?

Security issues

To mitigate the risks associated with cyber attacks, retailers should ensure compliance of the PoS components with the PCI standards, protect data with encryption, and apply multi-factor authentication practices.

Improper PoS installation

During the installation, collaborate with the PoS implementation company to ensure that it meets your requirements. Check these critical aspects in your installed system:

  • Wires and cables are properly installed and plugged in
  • Software is compatible with your devices
  • Inspect access to the system in different user roles
  • Make sure that the system is configured according to your requirements and all integrations function smoothly
  • Check if the internet connection is secure and strong to support your PoS activity

Waiting for your issues to be fixed by the PoS providers’ support team can interrupt your operations, so retailers can save time by preventing or learning to solve the most common problems themselves.

  • Properly train your staff to use your PoS system correctly and identify the most frequent issues
  • Get a secure remote access solution for your IT team to troubleshoot remotely
  • Run regular checks of your PoS system
  • Establish a process for swiftly addressing PoS problems with your services provider
