Real-World BNPL Platform Implementations
We don't just talk about building FinTech solutions; we deliver them. Explore how we've helped businesses like yours take control of their financing.
White-Label BNPL for a Major Online Furniture Retailer
Industry: E-commerce & Retail
Client Overview: A rapidly growing online furniture retailer with over $50M in annual revenue was experiencing high cart abandonment rates for large-ticket items. They were losing significant margin to third-party BNPL providers and wanted to create a branded, integrated financing experience to improve conversions and customer loyalty.
"Developing our own financing solution with CIS was a game-changer. We've not only seen a significant lift in sales but now we have direct insight into our customers' purchasing behavior. The platform is seamless, and the ROI was clear within the first year."
Key Challenges:
- High transaction fees (5-6%) from existing BNPL partners.
- Lack of control over the user experience and branding at checkout.
- No access to valuable customer financing data.
- Need for a solution that could handle high-value, long-term installment plans.
Our Solution:
We developed a fully white-labeled, API-driven BNPL platform integrated directly into their e-commerce checkout. The solution included:
- A custom risk engine tailored to their customer base and product categories.
- A seamless, on-site application process that delivered instant decisions.
- A customer portal for managing payments under the retailer's brand.
- A merchant dashboard for their finance team to track loan performance and settlements.
MVP Launch for a Venture-Backed FinTech Startup
Industry: Financial Technology (FinTech)
Client Overview: A startup founded by experienced FinTech professionals aimed to disrupt the BNPL market by focusing on a specific niche: home improvement services. They needed to build and launch a robust Minimum Viable Product (MVP) quickly to secure their Series A funding and onboard their first cohort of service providers.
"CIS was the perfect partner for our MVP. Their speed and expertise were incredible. They understood the urgency and delivered a scalable, secure platform that impressed our investors and allowed us to hit the ground running."
Key Challenges:
- Aggressive 4-month timeline to develop and launch the MVP.
- Limited initial budget requiring a focus on core, essential features.
- The need for a highly secure and scalable architecture to attract investors.
- Complexities of underwriting for service-based transactions versus traditional retail.
Our Solution:
We deployed a dedicated FinTech POD that worked in tight, agile sprints with the founder. We focused on building the core engine first:
- A streamlined onboarding process for both consumers and service providers.
- A flexible loan origination system to handle project-based financing.
- Secure integration with Plaid for bank verification and a payment processor.
- A functional admin panel for the startup's team to manage operations.
Digital Transformation for a Regional Bank's Lending
Industry: Banking & Financial Services
Client Overview: A well-established regional bank was losing its younger customer base to agile neobanks and FinTech apps offering modern, digital lending experiences. Their existing personal loan process was cumbersome and paper-based. They needed to launch a digital, app-based installment loan product to compete effectively.
"CIS helped us bridge the gap between traditional banking and modern FinTech. The new platform has revitalized our personal lending division, making us competitive with digital-first players and significantly improving our customer experience."
Key Challenges:
- Integrating a new digital platform with their legacy core banking system.
- Ensuring bank-grade security and compliance with all financial regulations.
- Creating a user experience that was simple enough for digitally-native customers.
- Retraining internal staff to manage a fully digital loan origination process.
Our Solution:
We architected a modern, microservices-based platform that acted as an agile layer on top of their existing core system. The solution featured:
- A branded mobile app (iOS & Android) for loan applications and management.
- Secure API gateways to communicate with the core banking system for funding and servicing.
- Integration of their own underwriting rules into an automated decision engine.
- A comprehensive admin portal for bank staff with role-based access and audit trails.
What Our Partners Say
We build more than software; we build long-term partnerships. Here’s what our clients have to say about their experience working with us on complex FinTech projects.
"The AI-powered risk module CIS built for us is phenomenal. It's more accurate than any off-the-shelf solution we tested and gives us a real competitive edge. Their team's deep understanding of machine learning in a financial context was impressive."

Frequently Asked Questions
The timeline varies based on complexity. A Minimum Viable Product (MVP) with core features can be launched in 4-6 months. A full-featured, enterprise-grade platform with advanced AI, extensive integrations, and mobile apps could take 9-12+ months. Our phased approach focuses on getting you to market quickly while planning for future scalability.
Initially, using a third-party service has a lower upfront cost. However, you pay 3-7% on every transaction, which erodes margins significantly at scale. Building your own platform is a strategic investment. The upfront cost is higher, but you eliminate transaction fees, own the customer data, control the user experience, and create a new revenue stream, leading to a much higher ROI over time.
We build the technical framework for compliance, but we are not a law firm. We partner with your legal and compliance teams to implement features that meet regulatory requirements, such as KYC/AML checks through trusted API integrations (e.g., Plaid, Onfido), state-specific interest rate caps, and transparent Truth in Lending Act (TILA) disclosures. Our systems are designed to be auditable and adaptable to changing regulations.
Our AI-powered risk engine uses a combination of machine learning models. We utilize supervised learning (like logistic regression and gradient boosting) on historical data to predict default risk. We also incorporate unsupervised learning to detect anomalies and potential fraud patterns. The system can analyze traditional credit data alongside alternative data points (e.g., transaction history, digital footprint) for a more accurate and inclusive assessment.
Absolutely. We design our BNPL solutions with a robust, API-first architecture. This allows for seamless integration with all major e-commerce platforms, including Shopify, Magento (Adobe Commerce), BigCommerce, and WooCommerce, as well as custom-built systems. We provide clear documentation and developer support to make the integration process as smooth as possible for your merchants.
