Overwork due to repeated work is the most common cause of burnout for business owners and their employees. A good choice of retail POS system can perform many retail processes and workflows on autopilot. From there, POS data analytics solve many business problems by saving valuable resources and time, such as:

  • Inventory management: Keep your inventory up to date by tracking sales and returns and forecast to calculate restocking to avoid deadstock and out-of-stock situations. Also, it can show what products are selling well and what aren’t for you to leverage the quantity.
  • Competitive analysis: Provides solid data and reports like business heatmaps, graphs, and charts so you can understand your company’s performance metrics relative to industry standards and compare them with competitors.
  • Customer experience enhancement: Optimize your customer’s omnichannel journey by integrating mobile, desktop, and in-person experiences. For example, when customers come to your store, the POS counter staff can quickly view their purchase history for suitable suggestions and cross-selling. Such small touches keep customers coming back because they love attention and recognition.
  • Loyalty program: Based on POS data, you can design personalized marketing strategies by tracking customer contact information and their purchases. POS systems can integrate with loyalty programs and customer databases to leverage customer engagement and help you gain more profit.
  • Staff performance: Create staff working schedules and track the sales of each staff to calculate wages and commissions.

In short, modern POS software retail helps you focus on more profitable areas such as consulting, customer care, and achieve new levels of success.

Benefits of POS systems in retail

POS technologies develop at a rapid pace to bring more and more ease, convenience, and comfort for retailers. When a retail POS can’t satisfy the needs of your business, it’s time to switch to a new system.

Some of the most common onset signs of an outdated POS are:

  • It’s impossible or difficult to sync data and manage inventory in real-time
  • It doesn’t support customer loyalty programs
  • It costs too much
  • It can’t help with staff management
  • It’s unportable to move around and take payments
  • It has no option for mobile devices

How to choose the right retail POS for your business

So far we’ve covered the basis details of retail POS. Now let’s look at the 5 essential steps you’ll need to take to get the right POS system for your retail.

  1. List your business requirements for your POS system
  2. Define your budget and prioritize
  3. Compare retail POS solutions based on your requirements
  4. Get a trial or demo of the retail POS
  5. Optimize your POS system for maximum business growth


No business owner wants to go through the retail POS system transition multiple times over a while. Therefore, you should outline the requirements for the POS solution you want before you start looking.

First, you can start with a simple question: How long do I need this solution to work for my business?

You should not stop at asking for today, but think about your expectations in the future as well. 2–3 years might be a reasonable time frame for a technology investment.


After deciding on a timeframe, you should consider the following questions:

  • How many stores will use the POS solution to operate?
  • Do I need to handle multiple growing stores at the same time?
  • Do I just need a simple POS system to handle in-store transactions?
  • What sales promotion do I want to run?
  • Do I want to integrate the POS with any other system such as Quickbook, MYOB, or Xero?
  • Which business operations are doing well and which are not
  • How important is it to synchronize data between the physical stores and online stores?
  • What types of data do I need to sync?
Your business requirements for the retail POS

Your customer experience may not be seamless because your eCommerce and in-store POS systems lack the connection. No matter how much manual effort you put in keeping everything in sync, you may still find an order for an item that’s actually out of stock.

So you can try mapping out your value chain, from supply chain to post-purchase customer care, and then look at each stage to find bottlenecks that could improve the customer experience metrics and profit margin. From there, you can check specifically how the future POS system can improve those stages.

  • Cost: Retailers can rely on accurate real-world data to identify and handle slow-moving or low-margin inventory flows.
  • Revenue: You can minimize the number of employees and optimize sales. You’ll also ensure accurate stocking of high-margin and best-selling products. In addition, you can implement promotions and loyalty programs to increase the average cart size.

Considering these 2 aspects will help you shape the most important features you need in a POS system for retail. Think about the strategy and methods you want to adopt. Then, gather all the challenges in as much detail as possible into a checklist of requirements for potential POS vendors.

Ease of use

Your retail POS needs to be user-friendly and easy for your employees to use without calling technical support or referencing the manual frequently.


Many POS systems have built-in POS and inventory system integration. However, you should also consider a POS developed in an open-source platform like Magento. They provide maximum integration capabilities via APIs to connect with other cooperating systems such as CRM and ERP.

PCI Compliance

You should choose a POS system that is compliant with PCI data security standards to safeguard customer payment data and minimize fraud payments.

In this step, you’ll need to determine how much investment you are willing to spend to achieve your goals and requirements within the defined timeframe, including:

  • Budget
  • Potential revenue
  • Costs you expect to save

You should break down each requirement of step 1 to determine investment costs and opportunity costs to prioritize the components.

The cost of a POS system includes 3 parts:

  • POS software: Your POS license will be one-time payment or subscription depending on different POS providers.
  • POS hardware: The average cost of a card processor is between $20–100. Other peripherals like a receipt printer, cash drawer, and tablet stand will cost you from $600 to $1,000.
  • Payment processing: Payment processing depends on the pricing scheme of your payment processor, accounting for 1.5–3.5% per transaction. You can visit our guide to know more about the average credit card processing fee.

Define your budget to invest in the retail POS system

Even the best retail POS solution sometimes has problems, or you simply want to customize to meet changing business needs. Therefore, a POS system isn’t only about purchase and installation, but also needs the support of a long-term partner to accompany your business growth.

  • What are my expectations for POS deployment and launching?
  • Do I want a dedicated project manager or will I oversee most of the system implementation on my own?
  • How do I want to receive support? How long do I expect to wait for the POS providers to respond? And through which communication channel?

We recommend working with a leading POS system to perform your daily tasks efficiently and achieve your business goals.
