Our approach

Intellias empowers financial institutions, fintechs, and other payment companies to build fast, secure, and scalable payment solutions. We take a collaborative and outcome-driven approach.

01

Discovery & strategy

We gather functional requirements, perform compliance & regulatory review (e.g., PCI DSS, PSD2, FedNow) establish business-centric roadmapping, and develop your platform and ecosystem strategy.

02

Technical design

Based on our assessment, we determine if it is better to buy a payment software product or build a custom system. Then we design the architecture, select the technology stack, and determine the integration architecture (banking core, payment gateways).

03

Agile development & QA

Next, our engineers create microservices & cloud native builds with API-first development practices and automated testing through CI/CD pipelines before we audit performance and compliance.

04

Integration & certification

Before implementation, our engineers validate the real-time flow of data, establish payment gateway integrations (Visa, Mastercard, SEPA, SWIFT), and connect KYC/AML tools, fraud engines, and acquirers.

05

Launch & continuous support

Finally, we begin to phase out your old system and support you as you go live. Our support continues through operation & user manuals, as well as continuous optimization and product scaling.

Get secure, lightning-fast payments from a modern system that won’t break the bank.

FAQs

We help companies build and manage modern payment systems by integrating payment rails, sponsor banks, and card-issuing infrastructure. Our services cover everything from handling interchange fees and compliance to optimizing performance across payment gateways. We also support high-load transaction processing and use AI/ML to improve payment efficiency and expense tracking. Our payment consulting team checks how your transactions are routed, learns where interchange fees are most expensive, and decides how to proceed. We also review fraud and chargeback handling to stop revenue leaks before they become a problem.

Yes, our payment processing consultants build systems that are secure by design. For fraud detection, we also deploy machine learning techniques that score transactions instantly and block threats while letting legitimate payments through. To stay compliant with global AML rules, we connect you to real-time watchlists and keep your transaction monitoring sharp as rules change. We also make onboarding smooth with secure eKYC flows that check IDs and confirm each user’s identity.

Integration is a big part of what we do. We build API connections that link your current bank platforms with modern networks like SEPA, SWIFT, and instant payment rails such as FedNow. If you accept Visa, Mastercard, UnionPay, or Amex, we design connections to ensure data stays secure in transit and at rest. We also test every connection.

Our vast expertise in building high-load payment processing systems for some of the largest banks and other FinTech businesses is what sets us apart. Our business model puts our clients’ needs first as the core of our services. We work alongside you as partners to design, build, and scale digital payment solutions. Our engineers map out the payment technology architecture that best fits your business and choose the tech stack that works in your environment. We follow the Payment Card Industry Data Security Standard (PCI DSS), so your data is not only secure but compliant. Because we practice CI/CD methods, we continue to improve your system even after it goes live.

AI can find patterns in existing data that give you an idea of how well your payment processing services are performing. You can see areas where everything is running smoothly and trouble spots. AI even lets you detect fraud before it happens. Therefore, we create dashboards that help you understand the data. This information then becomes part of your strategy. You can use this information to make a variety of business decisions, including improving pricing, adjusting operations to suit customer needs, or even launching new payment services. Furthermore, using AI results in smoother handling of edge payment cases, like better refund strategies.

We do. Our payment processing consultants will help you set up BNPL services that fit your business needs. We can use a trusted BNPL provider or build a custom BNPL system under your brand. Furthermore, we handle credit checks, repayment flows, and other methods to help your customers split payments. Our team also integrates BNPL data with the rest of the payment processing technology to unify data and ensure clear reporting.
