Tired of Payment Platforms That Can't Keep Up?

You're scaling globally, but your payment infrastructure is a complex web of gateways, processors, and acquirers. This patchwork creates data silos, increases costs, and slows down innovation. Building a unified commerce platform like Adyen isn't just about processing payments; it's about owning your entire financial stack to unlock new revenue streams, improve customer experiences, and gain a true competitive edge. We provide the blueprint and the AI-enabled engineering talent to build a platform that's not just a clone, but a strategic asset tailored to your specific business model.

Building a Unified Payment Orchestration Layer for a Global SaaS Leader

Industry: FinTech & SaaS

Client Overview: A leading B2B SaaS company providing subscription billing services to enterprise clients across North America and Europe. They were struggling with a fragmented payment infrastructure, relying on multiple third-party gateways, which led to high operational costs, inconsistent data, and difficulty in expanding to new markets.

"CIS didn't just build a gateway; they engineered a central nervous system for our entire payments operation. Their expertise in compliance and high-availability systems was a game-changer. We now onboard new markets in weeks, not months."
Michael Harper, CTO, ScaleUp SaaS Inc.

Problem

The client's growth was being throttled by their payment stack. Each new country required a new, complex gateway integration, increasing technical debt and maintenance overhead. They lacked a unified view of their transaction data, making reconciliation a nightmare and preventing them from optimizing payment routing for cost and success rates.

Key Challenges:

  • Integrating over 15 disparate payment gateways into a single, manageable system.
  • Ensuring PCI DSS Level 1 compliance for the new centralized platform.
  • Migrating millions of active subscriptions and tokenized payment methods without service interruption.
  • Developing an intelligent transaction routing engine to reduce processing fees.

Our Solution:

We designed and built a cloud-native Payment Orchestration Platform that acted as a single API layer on top of their existing gateways. Our AI-enabled team delivered a multi-faceted solution:

  • Unified API: A single, RESTful API for all payment operations, abstracting away the complexity of individual gateway integrations.
  • AI-Powered Routing: A machine learning model that analyzes transaction data in real-time to route payments to the acquirer most likely to approve it at the lowest cost.
  • Centralized Vault: A PCI-compliant, agnostic token vault to securely store customer payment data, giving the client full control and eliminating vendor lock-in.
  • Phased Migration Strategy: A carefully planned, zero-downtime migration plan that moved merchants and their subscriptions to the new platform region by region.

Developing a Real-Time Settlement System for a Logistics Giant

Industry: Logistics & Supply Chain

Client Overview: A Fortune 500 logistics company managing millions of shipments daily. Their existing payment settlement process was batch-based, running overnight, which created cash flow delays for their network of thousands of independent carriers and introduced significant reconciliation challenges.

"The real-time settlement platform from CIS transformed our relationship with our carriers. Paying them instantly upon delivery has become a major competitive advantage in a tight labor market. The system has been flawlessly reliable since launch."
Jenna Clay, VP of Operations, Global Freight Corp.

Problem

The 24-48 hour delay in paying carriers was causing dissatisfaction and churn. The manual, batch-based reconciliation process was error-prone and required a large back-office team to manage disputes and discrepancies. They needed a system that could handle complex, multi-party transactions and settle funds in near real-time.

Key Challenges:

  • Processing a high volume of transactions with very low latency.
  • Integrating with multiple banking systems and payment rails (ACH, FedWire).
  • Ensuring transactional integrity and creating an immutable audit trail for every dollar.
  • Building a complex rules engine to handle fuel surcharges, accessorial fees, and carrier advances.

Our Solution:

We engineered a high-performance, event-driven settlement platform using a microservices architecture. The solution was built for speed, accuracy, and auditability:

  • Event-Driven Core: Built on Kafka and Flink to process millions of transaction events (delivery confirmation, fee calculation, etc.) in real-time.
  • Smart Contract Logic: A custom rules engine that automatically calculated the final settlement amount based on predefined contractual terms for each carrier.
  • Direct Bank Integration: Secure, direct API integrations with the client's partner banks to initiate and track payments across various rails.
  • Reconciliation Dashboard: A web-based portal providing real-time visibility into the entire settlement lifecycle, dramatically reducing the need for manual intervention.

Building the In-App Payment & Wallet System for a Leading Ride-Hailing App

Industry: Transportation & Mobility

Client Overview: A rapidly growing ride-hailing company in the EMEA region, competing with global giants. To improve user experience and driver loyalty, they needed to move beyond basic credit card processing and build a sophisticated in-app wallet and multi-faceted payment system.

"CIS delivered a world-class payment and wallet system that is now the backbone of our user experience. Their ability to handle the complexities of split payments, driver payouts, and fraud in a mobile-first environment was exceptional."
Farid Al-Jamil, Founder & CEO, GoFast Mobility

Problem

The client was losing customers due to a clunky payment experience and drivers due to slow payout cycles. They couldn't support local payment methods, which was a major barrier to growth in new markets. They also faced a high rate of payment fraud from stolen credit cards.

Key Challenges:

  • Handling millions of micro-transactions securely and cost-effectively.
  • Building a closed-loop wallet system with top-up and withdrawal capabilities.
  • Implementing a complex split-payment system to route funds to drivers, the company, and tax authorities.
  • Developing a mobile-centric fraud detection system that didn't add friction for legitimate users.

Our Solution:

We developed a comprehensive, mobile-first payment platform integrated directly into their existing application. This was more than a feature; it was a core product pillar:

  • E-Wallet System: A secure, scalable digital wallet allowing users to store funds, earn rewards, and pay for rides instantly.
  • Automated Payout Engine: A system that calculated and disbursed driver earnings on a daily basis, significantly improving driver satisfaction and retention.
  • Local Payment Integrations: Deep integrations with regional mobile money providers and direct debit systems, unlocking new customer segments.
  • Behavioral Fraud Detection: An AI model that analyzed in-app behavior, location data, and transaction patterns to identify and block fraudulent activities in real-time.
