What's inside?
Being the backbone of the whole system, the architecture design of a payment gateway needs to be carefully built, for in-time adjustment to the structure and enhancing the performance in real-life launching. Helping in that time-consuming process, the essential features below are what online businesses need to build up a perfect payment gateway.
Payment Gateway System Design - Backbone Of The Payment System
A payment gateway system design, or payment gateway system architecture, is a functional framework of a technology platform that facilitates and manages online transactions, which securely transmits payment information between the customer, the merchant, and the payment processor.
This payment gateway system design is like the backbone of the completed payment system, developers created it in considering what should be in the structure, what can be omitted, what can be added in to fit with the business’s demands, etc.
The payment gateway system design is the backbone of a payment system.
Different industries will have different payment gateway functional framework that involves the integration of various components. This includes user interfaces, transaction flows, security measures, integration APIs, support for multiple payment methods, compliance with industry standards, scalability, and features for monitoring and analytics—all that to ensure secure, efficient, and reliable processing of electronic payments.
Indeed, a payment gateway system is an indispensable part that facilitates and manages online transactions of online businesses. Most e-commerce platforms, like Shopify for example, enable their merchants the flexibility in choosing payment methods by offering both internal payment gateway services – Shopify Payments, and Shopify third-party payment gateways.

3. Avoid double payment
-
4. Handle timeout and failure
-
5. Fast responses
A payment gateway system design that enables multiple payment methods is a versatile and customer-centric payment gateway. It ensures customer convenience by allowing their preferred payment method, leading to a positive user experience and increased conversion rates with a wider group of international audiences.
Merchants offer flexibility in online payment to cater to changing market demands, reducing business risks of losing customers. Moreover, offering various payment options fosters customer loyalty and satisfaction, contributing to higher retention rates.
Enabling multiple payment methods is a key functional feature in a payment gateway.
Security and privacy are the top concerns in cyberspace, and a payment gateway system design will minimize chargebacks by authenticating transactions and
enhancing overall financial security. Additionally, it contributes to brand reputation by demonstrating a commitment to user safety and fostering loyalty among customers. Ultimately, prioritizing the security of payment details is foundational for the long-term success, credibility, and resilience of a payment gateway service.
Consumer trust and confidence are paramount, as users must feel assured that their financial data is handled securely during online transactions. Regulatory compliance, notably with standards like PCI DSS, is mandatory to avoid legal repercussions and maintain the credibility of the payment gateway. Encryption and tokenization, are crucial for preventing fraud, cyberattacks, and identity theft, safeguarding consumers and merchants.
Double payments, or duplicate transactions, can occur due to technical glitches, user errors, or system failures. Duplicate transactions can lead to accounting discrepancies, operational challenges, and potential disputes. From a customer perspective, being charged twice for a single purchase can result in dissatisfaction and erode trust in the payment system.
A payment gateway system design that can prevent these duplicates is essential to uphold the integrity of financial records and maintain the trust of both merchants and consumers.
Building safeguards into the payment gateway, such as transaction validation checks, unique identifiers, and robust error-handling mechanisms, is necessary to effectively identify and prevent double payments.
Collaborating with various payment gateway providers allows businesses to reach a wider group of global customers.
When customers wait for the payment gateway to process, they will potentially leave for another better option, a better place with better and faster payment services.
That’s why merchants need to find themselves a payment gateway system design with the most innovative technologies. For them to increase their revenue, user experience on the site, trust and credibility, and more.
Customers want to pay and leave, not to put in their private data and wait for payments to be processed again due to failure. In the fast-paced realm of online transactions, delays can lead to frustration and hinder the perception of a reliable payment service.
Moreover, rapid response times contribute to the security of the transaction process by swiftly confirming or declining transactions, minimizing the window for potential fraud. A payment gateway system design offering a fast response feature also plays a crucial role in preventing duplicate transactions and managing real-time notifications for both merchants and customers.
To achieve fast response times, payment gateways must implement optimized and scalable architectures, employ efficient communication protocols, and leverage technologies that minimize processing delays.
The fast-response functionality in a payment gateway helps to reduce the number of abandoned carts and increase customer experience.
B. Non-functional features
Non-functional features specify criteria that are not related to specific behaviors or features but define how well the system performs those behaviors. They are often related to system attributes such as performance, reliability, usability, and security.
-
1. Offering no or low transaction fee
-
2. Highly consistent
-
3. Highly available
-
4. User-friendly UX/UI
-
5. Scalable
Though finding a payment gateway provider with no or low transaction fees might be challenging, as the payment gateway typically charges several types of fees to cover the costs of processing transactions and providing their services, it’s still not impossible to find a payment gateway with competitive and reasonable transaction fees. The key is to carefully research and compare different providers to identify the one that best fits your business needs and budget.
In case you find this a time-consuming task, you may want to take a look at our top picks on payment gateway with the lowest transaction fee.
Consistency in processing transactions helps maintain a coherent and error-free record of financial data, reducing the risk of discrepancies and ensuring accurate accounting for both merchants and users. This consistency is vital in preventing double payments, ensuring that each transaction is processed accurately and reflected consistently across all relevant records.
Moreover, a highly consistent payment gateway enhances the overall trustworthiness of the system, fostering confidence among users and merchants in the accuracy and dependability of the financial transactions facilitated by the platform.
A highly available payment gateway system design minimizes downtime, and is essential for processing transactions in real-time, ensuring that the payment gateway is operational and always accessible. This is crucial in the fast-paced world of online transactions where any service disruptions can lead to financial losses, inconvenience for users, and damage to the reputation of the payment gateway provider.
It also supports the overall resilience of the payment infrastructure against technical failures, cyber threats, or unexpected events. By prioritizing high availability, a payment gateway ensures that users and merchants can rely on the system to facilitate secure and efficient financial transactions without the risk of service interruptions, contributing to the trustworthiness and success of the payment gateway platform.
A user-friendly User Experience (UX) and User Interface (UI) are essential in building a payment gateway to enhance customer satisfaction, streamline the payment process, and reduce errors.
A well-designed interface ensures that both merchants and consumers can easily navigate through the payment gateway, fostering a positive interaction. A clear and intuitive UI in the payment gateway system design contributes to a seamless and efficient payment flow, enhancing overall customer experience and encouraging repeat usage. Intuitive interfaces with well-labeled features and straightforward navigation make it easier for merchants to manage transactions, access analytics, and resolve issues.
A User-friendly interface is reportedly to help increase the conversion rate and customer loyalty of an online business.
A scalable architecture enables the payment gateway to handle increased transaction loads efficiently, whether due to business expansion, seasonal spikes, or unforeseen surges in demand. Scalability is essential to prevent system bottlenecks, maintain fast response times, and support the growing number of user base and transactions.
It also contributes to cost-effectiveness by allocating resources dynamically based on demand, preventing overprovisioning or underutilization.
The above are essential features that e-commerce businesses need to consider for their payment gateways. By addressing these two types of functional and non-functional features, a payment gateway system can ensure not only the correct processing of transactions but also the reliability, security, and performance necessary for a seamless user experience.

Frequently Asked Questions
How is the payment gateway designed?
A payment gateway is designed to facilitate secure online transactions between customers and merchants. The process begins with a customer initiating a transaction on an e-commerce site, with the payment gateway encrypting sensitive information. This encrypted data is then sent to the payment gateway, which validates and forwards it to the acquiring bank for authorization.
The acquiring bank checks the customer's account for funds and sends an authorization response to the payment gateway. The customer is notified of the transaction status, and if approved, the payment gateway initiates settlement, transferring funds from the acquiring bank to the merchant's account.
Security measures, including encryption and fraud detection, are integral to the design. The payment gateway maintains transaction records for accounting and dispute resolution. The entire process ensures a seamless, secure, and efficient online payment experience for customers and merchants alike.
How do you build a payment gateway?

Creating a payment gateway is a complex and challenging task that involves a deep understanding of financial regulations, security protocols, and industry standards. While it is theoretically possible to build a payment gateway on your own, there are several significant challenges and considerations to keep in mind:
Security and Compliance: Payment gateways handle sensitive customer information, and any security lapses can have severe consequences. Adhering to industry standards, such as PCI DSS compliance, is crucial. Meeting these requirements is complex and requires specialized knowledge.
Legal and Regulatory Considerations: The financial industry is highly regulated. Building a payment gateway requires compliance with various national and international regulations. Navigating legal requirements can be challenging and may require legal expertise.
Partnerships with Financial Institutions: A payment gateway needs to establish partnerships with banks or financial institutions to facilitate the processing of transactions. Building these relationships requires industry connections and trust.
