Building, optimising, and future-proofing existing infrastructures with payment gateways

about the project

In an increasingly competitive digital commerce landscape, businesses must deliver fast, secure, and seamless payment experiences to meet customer expectations and scale operations. When a rapidly growing eCommerce brand approached Aisling to transform its aging payment infrastructure, the goal was clear: modernise the system, reduce friction at checkout, and build a future-ready platform that could handle global expansion. Through a strategic, three-phase approach—build, optimise, and future-proof—Aisling delivered a robust solution that streamlined payments, improved performance, and positioned the company for long-term success.

The Challenge

The client, a mid-sized eCommerce retailer operating in North America and Europe, was facing a set of challenges common to many scaling businesses:

  • A legacy payment system that lacked flexibility and was difficult to maintain

  • Frequent transaction failures and long settlement times

  • Limited support for modern payment methods like Apple Pay, Google Pay, and Buy Now, Pay Later (BNPL)

  • No clear roadmap for integrating global currencies or compliance with regional regulations

As the business prepared to expand into new international markets and launch a subscription-based product line, it became evident that the current infrastructure would not scale with demand.

The Solution: Aisling’s Three-Phase Approach

1. Building a Modern Payment Foundation

Aisling began with a full audit of the company’s existing payment stack, including integrations, processing flow, customer touchpoints, and security posture. Based on this analysis, we recommended and implemented a modern payment gateway that offered:

  • Seamless integration with the company’s eCommerce platform and backend ERP

  • Multi-currency support for cross-border sales

  • Compliance with PCI-DSS and GDPR standards

  • Developer-friendly APIs for future customisation

We worked closely with the client’s internal IT and finance teams to execute a smooth migration with minimal disruption to daily operations.

2. Optimising for Performance and Conversion

After stabilising the core infrastructure, Aisling focused on enhancing payment performance and user experience:

  • Implemented one-click checkout and tokenisation to speed up repeat purchases

  • Integrated support for digital wallets, BNPL, and local payment methods

  • Automated reconciliation and real-time reporting tools for the finance team

  • Reduced checkout abandonment through UX adjustments and A/B testing

As a result, transaction success rates increased by 22%, and cart abandonment dropped by 18% within the first three months.

3. Future-Proofing for Scale and Innovation

With the infrastructure now modern and optimised, Aisling helped the client design a roadmap for long-term scalability. This included:

  • Adding redundancy across payment processors to reduce single-point failure risks

  • Preparing APIs for mobile app integration and subscription billing logic

  • Building a compliance framework to support upcoming regulations in APAC markets

  • Implementing AI-driven fraud detection to scale with growing transaction volumes

Aisling also provided ongoing strategic IT consulting and support, ensuring that the client could confidently enter new markets and channels with a future-ready payment system in place.

The Results

Conclusion

This engagement is a prime example of how Aisling helps businesses transform their IT and operational infrastructure to meet today’s demands and tomorrow’s opportunities. By building a modern payment ecosystem, optimising it for performance, and future-proofing it for growth, Aisling empowered the client to scale with confidence and stay ahead of the curve in a fast-moving digital market.
