What Is a POS System?

A Point of Sale (POS) system is an integrated software and hardware solution for both big and small businesses to manage sales. POS systems take the place of conventional cash registers by handling transactions, plus POS systems can:

• Process all types of payments
• Track inventory
• Manage your accounting needs
• Calculate sales tax
• Track employee work hours, vacation time, and absences
• Handle payroll
• Manage loyalty programs
• Track sales history
• Calculate pricing and discounts

How Does a POS System Work?

A POS system is made up of 2 main parts—first, there's the hardware, including a printer, cash drawer, and a POS terminal. Then there's the software, which is the computer program that operates the whole system. A POS system works by connecting your credit card processing apps, accounting apps, inventory apps, and other point of sale-related business apps into a single unit.

The Types of POS Software and Their Costs

There are 4 main types of POS software:

1. Mobile POS software

This software is cloud-based and comes as an app on your smartphone or tablet. It’s usually compatible with a receipt printer and a credit card swiper, but not as powerful as a full terminal POS system. It’s ideal for sole traders such as plumbers or mobile food cart owners.

2. Tablet POS software

The tablet version is similar to mobile POS software, but offers more features and capabilities. You could use tablet POS software to manage a large and complex retail organization, including inventory tracking, employee time tracking, payroll, and accounting. They are compatible with many POS hardware solutions to form a complete POS system for any situation.

3. Terminal POS software

This is a fixed POS software with full back-office capabilities. It can be cloud-based or on-premise. Terminal POS software is best suited to large retail stores, spas, malls, and other brick and mortar big or small businesses.

4. Self-service or unattended POS software

This is designed to be used in kiosks and outdoor units where it's not practical to post an employee. It is often integrated with another POS system nearby, like to provide an extra sales point in a busy grocery store. It can be cloud-based or on-premise since it's not used with a mobile system.

You’ll also find POS software designed for the unique needs of specific industries, such as restaurant and hospitality businesses, apparel retail, financial services, academia and education, and pharmaceuticals POS software.

The costs of your POS software will vary depending on the type of software you choose. Mobile POS software such as a smartphone app can begin as cheap as $50 per month, while more complex software can reach several hundred dollars monthly. When you buy POS software, you’ll usually need to pay an upfront purchase price, plus an ongoing monthly or yearly payment processing fee.

Other factors that may affect the cost of your POS software include:

• How many features you add
• Any hardware included
• Number of integrations
• Your operating system

Getting the Right POS Hardware

POS hardware is the indispensable other half of your POS system. You’ll need to get the right hardware to match the actions and transactions you want to carry out using your POS system. A basic set of POS hardware consists of:

• Printer to offer hard copies of receipts (retail stores, restaurants, and other brick and mortar small businesses are likely to need this)
• A POS terminal, or iPad or Android tablet to run your POS software
• Credit card reader
• A cash drawer to keep cash transactions secure and logged into your system

Depending on your business, you might also need:

• Extra tablets so wait staff can process orders at the table in restaurants
• A router to strengthen your internet for cloud-based POS systems
• A local server to host your on-premise POS software
• Weight scales for food retailers
• Barcode scanners
• Networking cables to connect all of your hardware
• An extra kitchen printer
• Self-serve checkout kiosks

The Benefits of a POS System For Your Business

With a POS system, your business can retain more customers through a better, targeted loyalty program and you can also track inventory so that you never run out of stock unexpectedly. A POS system can help you run complex discount offers when appropriate.

With the right POS system, you can also analyze sales history to discover seasonal buying trends and correlations, which can come in useful when you want to increase sales. You can also remove manual error by using barcode scanners and automatic synchronization, as well as combat absenteeism with a more reliable employee tracking system.

Other major benefits include improving payment security as well as the ability to make more sales thanks to your ability to accept more types of payment.

Cloud-Based vs. On-Premise POS Systems

A cloud-based POS system stores data on remote servers and can be accessed online, whereas a traditional or on-premise POS system stores data on a local server and can be accessed through an internal network. Here’s a breakdown of the main differences between a cloud-based POS and an on-premise POS:

If you have long-term business plans and if your requirements are likely to continue to evolve as your business grows, then a cloud-based POS system is probably the best choice for you. On the other hand, if you have fixed needs or a small budget, you might be best served by choosing a traditional POS system.

How to Choose a POS System Provider

Asking yourself these questions will help you choose the right POS system provider:

• What features do I need?
• Do I want to save money upfront or keep my monthly costs down?
• What hardware do I need? If you need a lot of items, a provider that bundles hardware together with the software is a better bet, but if you're going to be using your existing iPad, you’ll need something different.
• Does it integrate well with my existing business apps?
• Is the pricing transparent?
• Is it easy to set up and use? If it’s more complex, does it offer training?
• What analytics does it offer and what metrics can it check? Make sure that the ones that are most important to you are included in the package.
• How good is the customer service?
• Is it simple to scale up as your business grows?
