Executive summary
- Context: A leading digital payment services provider needed to scale its core platform to support international expansion and growing transaction volumes. At the same time, it required maintaining strict regulatory compliance and sub-second processing speeds.
- Approach: Working closely with the client's team, the joint project broke down the core platform into flexible, independent services, added automated testing, and expanded payment options across new global markets.
- Impact: The FinTech company successfully expanded to support payments across 50 countries and doubled its monthly transaction volume. Simultaneously, it reduced processing issues and automated 99.95% of transactions end-to-end.
The context
This FinTech company provides digital payment software that handles money transfers for businesses, banks, and fintech platforms. As the company grew, it needed a system that could automatically process millions of transactions across dozens of countries without slowing down or introducing inaccuracies.
Building on the platform’s strong technical foundation, it was upgraded to process more payments securely across major European payment rails (such as SEPA, CHAPS, and BACS). The updates supported new cross-border and instant payment options, maintained fast transactions, and met strict regulatory deadlines (including CASS and SWIFT ISO 20022) without compromising reliability or speed.
Leveraging existing capabilities, the joint initiative focused on three key goals:
- Expand system capacity: Upgrade the core payment setup to process higher transaction volumes instantly, even during complex, high-traffic periods.
- Evolve core architecture for agility: Break down the main system into smaller, self-contained components so engineering teams can update payment features quickly without affecting other parts of the business.
- Expand international capabilities: Update the system to automatically adapt to each country's unique payment rules, currencies, and security checks, making it seamless to enter new global markets.
The approach
Parser partnered directly with the client’s engineering, product, and compliance teams; the joint group ensured full operational continuity and unified technical leadership as business demands expanded.
Working together, the team focused on three critical areas:
- Modernising the payment core: Leveraging internal domain expertise, the team rebuilt the core platform to handle far more traffic without affecting payments’ performance. By splitting the system into flexible, independent components, the client can now quickly add new payment channels and expand into new countries without disrupting daily operations.
- Building quality into delivery: The team built automated testing into the development process early on. They also introduced real-time checks and parallel updates to prevent errors and keep transactions accurate during software releases.
- Meeting strict regulatory deadlines: Our teams collaborated to launch critical compliance tools and global security gateways on schedule. This enabled the team to roll out major new features, such as direct bank debits, smoothly, bringing services to millions of customers without delay.
The impact
- Expansion across 50 countries: Scaled operations securely into 49 additional countries by implementing flexible, international compliance gateways.
- 2x transaction volume growth: Safely doubled monthly transactions while sustaining high processing speeds.
- 99.95% end-to-end automation: Maintained exceptional operational efficiency by automating 99.95% of transactions, effectively eliminating manual processing delays and reducing operational costs.
- Reduction in payment processing errors: Automated verification and tracking reduced payment errors and delays, improving settlement accuracy.
- 40% faster deployment cycles: Accelerated deployment times, enabling the team to roll out new features and improvements multiple times a week without delay.
- Zero-compromise compliance: Met strict international security and financial standards, including PSD2, PCI-DSS, and ISO 20022, while improving internal quality ratings.
