Overhauling a Global B2B Marketplace’s Payment System
A seamless, secure payment system is essential for success in today’s competitive B2B marketplace, especially as businesses expand globally. When a prominent B2B marketplace enlisted QSoft to modernize its payment infrastructure, the goal was to enhance international payment capabilities, boost transaction speeds, and implement advanced fraud detection. The marketplace’s legacy system was struggling to scale with a growing global user base, resulting in inefficiencies and vulnerabilities that risked both customer trust and operational stability. QSoft’s integration of microservices architecture, global payment gateways, and AI-driven fraud detection transformed the platform, equipping it to handle global transactions with optimal speed, security, and scalability.
Navigating Complex International Payment Regulations
One of the most critical challenges faced by global B2B payment platforms is the complexity of managing international payment regulations. The B2B marketplace operated in multiple countries, each with unique compliance requirements, tax laws, and financial regulations. The existing infrastructure struggled to navigate this regulatory complexity, leading to slow payment processing and compliance issues. Without a scalable and flexible solution, expanding into new markets posed significant obstacles, risking regulatory violations and hindering the platform’s growth in the global marketplace.
To overcome this challenge, QSoft implemented a scalable microservices architecture tailored to the needs of the B2B marketplace. The new architecture allowed the platform to modularize payment processes and improve payment gateway integration, ensuring that each microservice could manage distinct tasks like currency conversion, tax handling, and regulatory compliance. This modularity offered the platform the flexibility to adapt to different regional requirements and quickly respond to changes in global financial regulations.
QSoft integrated Stripe and PayPal, two industry-leading global payment gateways, to handle multi-currency transactions and ensure compliance with regional tax laws such as VAT and sales tax. These gateways provided real-time currency conversion and automated tax calculations, which were previously bottlenecks in the transaction process. By leveraging Spring Boot to develop microservices and AWS Lambda for on-demand compliance checks, the platform achieved automated enforcement of local regulations. For instance, when a transaction occurred in the European Union, a Lambda function applied GDPR compliance and calculated VAT in real-time.
The system also incorporated AWS Config for continuous monitoring of regulatory changes, ensuring the payment infrastructure remained compliant with evolving global laws. This was particularly critical in regions like India, where Goods and Services Tax (GST) calculations needed to be applied automatically before transactions were finalized. With Amazon CloudFront, the platform further optimized the global delivery of payment processing requests, reducing latency for users across multiple regions.
Results: By implementing a microservices-based payment system and integrating global payment gateways, QSoft helped the marketplace reduce transaction times by 50%. The platform’s ability to automatically handle multi-currency payments, regional taxes, and compliance requirements enabled it to scale into new markets without encountering regulatory issues, improving global transaction efficiency and user satisfaction.
Enhancing Security with AI-Powered Fraud Detection
As the platform grew, its vulnerability to online payment fraud increased. The existing infrastructure lacked the agility to integrate modern fraud prevention tools, leaving it exposed to risks such as unauthorized transactions and identity theft. Additionally, the marketplace’s legacy systems were slow to process data from new fraud detection algorithms, making it difficult to prevent fraud in real-time. This posed a severe threat to both the financial stability of the platform and the trust of its global user base.
QSoft addressed this challenge by integrating AI-powered fraud detection with machine learning algorithms built on Amazon SageMaker. This allowed the marketplace to process and analyze payment data in real-time, detecting anomalies and suspicious activities across millions of transactions. SageMaker’s machine learning models were trained using historical transaction data and applied advanced algorithms like Isolation Forest to detect patterns associated with fraudulent behavior, such as multiple high-value transactions within a short period or transactions originating from high-risk regions.
To further enhance security, QSoft implemented AWS WAF (Web Application Firewall) and AWS Shield to protect the platform against DDoS attacks and malicious traffic. The fraud detection system was closely integrated with these services, providing comprehensive protection from both automated threats and human-driven fraud attempts. By deploying end-to-end encryption using AWS Key Management Service (KMS), the platform ensured that all payment data remained secure, both in transit and at rest.
Amazon Cognito was also integrated for user authentication, enabling multi-factor authentication (MFA) and identity verification. This added an extra layer of security, ensuring that only authorized users could access payment features and reducing the risk of unauthorized transactions. Amazon CloudWatch provided real-time monitoring of transaction activity, allowing security teams to react immediately to any flagged transactions. Suspicious activities, such as transactions originating from unusual locations or accounts with inconsistent histories, were automatically blocked or flagged for further investigation.
Results: With the integration of AI-powered fraud detection, the platform reduced fraudulent transactions by 70%, significantly enhancing security and protecting both buyers and sellers. The move to real-time fraud prevention allowed the marketplace to swiftly respond to emerging threats, minimizing financial losses and preserving user trust. Combined with the transition to a microservices architecture, the marketplace also experienced a 50% improvement in transaction processing speeds, delivering a more secure and efficient user experience.
