What is a POS System?

A point of sale is a comprehensive software and hardware solution that helps businesses to process the transactions of sales efficiently. The global POS terminal market size was estimated at USD 113.38 billion in 2024, and is projected to reach USD 181.47 billion by 2030, growing at a CAGR of 8.1% from 2025 to 2030. Furthermore, the transaction value for mobile POS payments is projected to reach US$25.31 trillion by 2030. The digits depict that the POS system has the tendency to grow at an exponential rate.

With the help of these components, a POS system in place can smooth the checkout processes, reduce the risk of errors, and enhance customer service. For businesses looking for tailored solutions, harnessing POS software development solutions can help them create customized POS systems. 

How Does a POS System Work?

You need to understand that a POS system works by combining hardware and software to facilitate smooth sales transactions and real-time business management. When a client makes a purchase, the system tends to capture the transaction details through a different set of devices, like barcodes or even touchscreen interfaces. 

It is the POS system in place that processes the payments through several methods like credit/debit cards, mobile-wallets, cash, or even contactless payments, thus ensuring security and speed. Moving ahead, it is the POS system that updates the inventory levels, manages the customer information, and records the sales data for detailed reporting and analytics. It is this seamless coordination that helps businesses to easily track their stocks, monitor sales trends, and optimize operations efficiently.

Then, a cloud-based POS system helps businesses with remote access, multi-store synchronization, and efficiency, which can be of great advantage to enterprises. If you’re someone looking forward to tailoring your POS system to fit your unique business needs, then investing in an expert custom POS software development can help you boost your overall performance.

The first and foremost step is to analyze the type of POS system that would fit in with your business needs. The most common types of POS systems are: self-service kiosks, mobile POS systems, and desktop POS systems.

Self-Service Kiosks

Such a system in place helps the customers to place orders or make payments independently. Most of the time, these services are seen in quick-service restaurants, theatres, and airports. They work in the best possible ways to enhance operational efficiency, reduce wait times, and empower customers to control their transactions. 

Mobile POS Systems

Mobile POS systems work on devices that are handheld, such as smartphones and tablets. Such systems usually have inculcated card readers that can easily be connected to the smart devices, thus making the mobile POS system more flexible and portable. The major benefit of these systems is mobility. Simply put, it allows businesses to take payments anywhere, thus making them useful for on-the-go or temporary setups like food trucks, market stalls, and much more.

Desktop POS Systems

These are POS software installed on the computers with a dedicated workstation or terminal. These systems are quite versatile and can be used by various businesses with a fixed checkout location. A desktop POS system can offer several features to businesses, including inventory management, sales reporting, and employee tracking.

Step 2: Decide on Data Storage

The next crucial aspect is to decide on the aspect of data storage. That said, choosing between on-premise and cloud-based data storage for a custom POS software architecture involves considering various factors related to your business needs, budget, technical requirements, and scalability. To understand and get clarity on which one to pick, let us compare both, keeping in mind a few factors. 

Factor 1: Cost Considerations

• On-Premise: When it comes to cost consideration, the upfront cost can be much higher. This cost integrates the cost of server hardware, equipment needed for the network, and the cost associated with setting up to maintain a physical space. 

• Cloud-Based: The cost of cloud-based is initially lower. However, there will be ongoing costs for subscriptions. These solutions are often based on a pay-as-you-go model, thus allowing you to scale your storage as per your business needs. 

Factor 2: Scalability

• On-Premise: Scaling on-premises can be complex and time-consuming. For instance, if your business experiences growth, chances are you will have to invest in additional hardware and infrastructure upgrades. 

• Cloud-Based: Based on your business requirements, with a cloud POS system design, you can very easily adjust and make changes in your storage capacity by either scaling up or down, without investing in hardware. 

Factor 3: Management and Maintenance

• On-Premise: For on-premise solutions, it will be your development team responsible for the updates, hardware maintenance, and security. Though this needs ongoing monitoring and can be resource-intensive.

• Cloud-Based: Cloud providers are responsible for looking after the maintenance, updates, and security of the infrastructure. This gives the IT team the time to focus on other important areas.

Factor 4: Accessibility and Remote Management

• On-Premise: In terms of accessibility, with on-premises, it can be daunting for remote access and management. It might require additional configuration for secure remote access.

• Cloud-Based: With cloud solutions, you get convenient remote access, which allows authorized users to manage the system from anywhere with an internet connection.

Factor 5: Compliance and Security

• On-Premise: With on-premise, you will have direct responsibility and control over the security measures implemented. This can prove to be beneficial, as having utmost security is usually the most daunting part of hospitality or restaurant POS systems.

• Cloud-Based: Usually, the cloud providers invest heavily in integrating the latest security measures, yet again, you will have to ensure that the chosen provider complies with the relevant industry standards.

Factor 6: Backup Recovery

• On-Premise: Here, the responsibility of implementing a robust backup recovery mechanism is entirely on you. This could involve additional costs on your side.

• Cloud-Based: Cloud providers do offer some type of automated backup and recovery mechanism as an integral part of their services.

Step 3: Decide on Important Integrations

1. CRM Integration

Including a CRM system in your POS helps you manage the customer information, their preferences, and interactions with ease. That said, you can consider adding features like tailored customer experience, targeted marketing, and loyalty programs. 

2. Inventory Management System

By integrating an inventory management system in place, you can be assured of accurate tracking of your product levels. This works in the best possible ways to stay ahead of stockouts, and it polishes and streamlines replenishment processes. 

3. Employee Management System

With the help of an employee management system in place, you’ll easily be able to streamline the workforce-related processes, such as scheduling, time-tracking, and performance management. It’ll cut down on over-staffing situations and ensure accurate payout calculations.

4. eCommerce Platform

Combining your POS with an eCommerce platform aligns both the online and offline sales. It works in the best possible ways to provide one of the best experiences to the customers, thus ensuring centralized order management. 

5. Payment Processor

If you want to secure and make your payment transactions efficient, then integrating a payment processor can be of great benefit. It helps in reducing the transaction time and improves the overall checkout experience. 

Step 4: Select the Necessary Features

The next step is to choose and include the most necessary features. The list of POS basic features includes features like transaction processing, inventory management, hardware integration, sales reporting, multi-location support, employee management, and security features. Depending on how you’d want to customize your POS software development, you can integrate these features and get started. 

Step 5: Pay Attention to UI/UX Design Elements

Now moving ahead, the next step is to pay utmost attention to your UI/UX design. That said, for the frontend of the POS system, there are two categories that you’ll have to focus on: UI/UX for customers and UI/UX for administrators.

For customers, UI/UX ensures that you focus on: intuitive navigation, streamlined checkout processes, user-friendly touchscreen interface, clear product scanning, responsive error handling, payment options, user assistance and guidance, and accessibility features. 

On the other hand, in UI/UX for administrators, ensure that you pay attention to: intuitive navigation, dashboard overview, role-based access control, efficient search and filtering, real-time updates, transaction management, inventory control, and employee performance tracking. 

Step 6: Get Started with Backend Development of POS System

The next step in the POS software development is to get started with the backend development of the POS system. For the backend development, ensure that you look for a scalable architecture based on the specific requirements of the POS system. Then, implement end-to-end encryption for the security measures. 

Step 7: Proceed to the POS System Testing

After you’re done with all the steps of POS software development, the next step includes proceeding to the final testing of this system. Ensure that you use all the different approaches from functional testing, integrational testing, to user acceptance testing. This will ensure that your POS system meets the requirements and the expectations of the actual users, and they will be able to validate its usability and functionality. 

Step 8: Implement, Maintain, and Scale your POS System

The last step in POS software development is to implement, maintain, and scale your POS system to stay ahead of the competition. Ensure that you deploy your POS software in the live environment, then ensure its smooth integration with the existing hardware, business operations, and payment gateways.

Then, the next step would be to make sure that you regularly monitor the performance of the system. Gather real-time user feedback and improve the software. Furthermore, plan for the future growth by optimizing the software architecture to handle the increased transactions, adding new features based on the latest market trends.
