FinTech development

FinTech, or Financial Technology, refers to digital technology for financial services—payments, financial management, credit, and investments. FinTech development involves building these services in accordance with the security, traceability, and regulatory compliance requirements that financial data demands. At Quality Think, we build digital solutions that help FinTech companies create secure, fast, and user-friendly experiences.

Technology that simplifies finance

Do you have an idea for a new payment service, a financial management tool, or a platform designed to simplify financial processes? We love taking on complex financial challenges and transforming them into secure, intuitive, and scalable technical solutions. Payment flows, KYC processes, investment platforms, digital banking interfaces, mobile apps? We’ll take care of it.

Don't let technology stand in the way of trust

In fintech, trust is everything. A complicated onboarding process, an unclear interface, or a slow process is enough to lose a customer. We solve that. When we build fintech solutions, we always put security and user-friendliness at the center. Whether it’s building a new payment platform, integrating open banking APIs, or creating digital onboarding flows, we ensure that the technology always builds trust—not undermines it. PSD2 makes that balance a technical requirement: your APIs must be open to third-party providers while also being protected by strong customer authentication, explicit consent, and traceability in every call.

Here's how we build when requirements are based on financial data

Secure Logins and Access Control

Authentication is rarely just a login box. We build customized solutions for secure logins and strict, role-based access control, so that each user can only access what they’re actually supposed to. The same principles apply when it comes to protecting account permissions, authorizations, or customer records.

Encryption and Protection of Sensitive Information

All traffic is encrypted using SSL and HTTPS, ensuring that passwords and personal data cannot be intercepted as they travel between the user’s device and the service. We distinguish between what can be stored and what is merely passing through, and protect public forms and APIs against automated attacks—including with reCAPTCHA v3—without creating obstacles for your legitimate users.

GDPR from the Architecture Upward

Personal data in financial services is rarely collected on a voluntary basis—which makes it all the more important that it is handled correctly. We build our systems in accordance with the GDPR from the ground up: data minimization, clear consent, documented retention periods, and logging that makes it possible to determine retrospectively who did what and when. If needed, we help conduct security audits of existing systems.

Post-Launch Management and Monitoring

A financial service isn’t secure at launch—it’s kept secure. Through QT Support, we take responsibility for the codebase, frameworks, plugins, and databases, providing ongoing security updates and automatic monitoring that alerts us to any anomalies. You can reach us weekdays from 8 a.m. to 5 p.m. via the help desk or by phone and receive a response the same day, with full transparency regarding the status and time spent on each case.

Financial flows we have already implemented in production

Automated invoicing via the Fortnox API with OAuth management, duplicate protection, and reconciliation against the customer’s history and delivery terms. Gift cards issued and redeemed at partner stores, a platform with integrations with WooCommerce and Sitoo. Klarna integrations in e-commerce platforms. Role-based access control and encrypted remote access in a VPN platform for industrial routers.

None of the customers behind them are fintech companies. The requirements for traceability, authorization, and ensuring that a transaction is never recorded twice are the same.
