FinTech Software Development Services

We build payment and billing systems, pricing and analytics platforms, customer-facing financial dashboards, client portals, and the secure backends behind them using React, Node.js, Python, .NET, and AWS.

Recent work includes Tie's configurable subscription-billing system and Longtail's autonomous airline-pricing analytics platform. We integrate Stripe, PayPal, banking APIs, and KYC/AML providers into a compliant, scalable architecture.

Yes, we build the core components these platforms depend on: real-time data pipelines, pricing algorithms, and secure analytics dashboards. For Longtail, an autonomous airline-pricing platform, we built and own the customer-facing analytics dashboard and admin console on a NestJS + PostgreSQL backend, AWS infrastructure (Terraform, Lambda, RDS), and Auth0 identity, shipping to production on every merge.

We build configurable payment and subscription-billing systems and integrate gateways like Stripe and PayPal. For Tie, we rebuilt the billing subsystem on Salesbricks with a configurable "bricks" pricing model and migrated active subscribers off Chargify with zero billing disruption. For Bookis, we built Stripe and Vipps payment flows plus a dynamic, AI-driven pricing engine that analyzes competitor listings to set prices automatically.

Security is built in from day one: end-to-end encryption, multi-factor authentication, secure APIs, and regular penetration testing. Our information-security management follows ISO 27001, with formal certification in its final stage, and we architect to meet PCI DSS, GDPR, and PSD2 requirements. We integrate KYC/AML providers for identity and anti-fraud checks, with audit logging and role-based access on every build.

A fintech MVP averages around $40,000, typically $30,000–$50,000 depending on features. Full-scale platforms with KYC, payment processing, and analytics can exceed $200,000. Cost depends on integrations, compliance scope, and timeline.

After a short discovery phase, we provide a detailed estimate broken down by module and sprint, so you can prioritize against budget.

A fintech MVP typically takes 8-12 weeks; a full-scale product with KYC, payment processing, and analytics runs 4-6 months or more. Discovery usually takes 1-3 weeks. We work in Agile sprints, delivering usable components early and iterating on your feedback, so you see working software well before the full build is complete.

Yes, and we recommend it. We begin with a short discovery phase to define the scope, then build a focused MVP that proves the core financial workflow with real users before scaling. This de-risks the investment: you validate demand and compliance assumptions early, then grow the architecture as adoption increases, rather than overbuilding before you have a market signal.

Look for proven payments and compliance experience, named clients with shipped outcomes, and engineers who stay for the long haul. DBB Software brings payment and billing depth (Tie's Chargify-to-Salesbricks migration), real-time analytics (Longtail's airline-pricing platform), and embedded teams that own infrastructure end-to-end, all built to fintech security standards.
