Fintech software development
Back office, bank and payment gateway integrations, reconciliation and reporting, with roles and change logs from day one. From €2,000 + VAT.
01 — What we do
Fintech software services we provide
- 01
Payment gateway integration
We connect products to Stripe, Adyen, and similar providers, handling checkout flows, tokenization, refunds, and webhook-driven reconciliation.
- 02
Secure transaction data handling
We design data models and access controls around the assumption that transaction records are sensitive by default, with encryption and audit trails built in.
- 03
Real-time financial data sync
We build systems that keep balances, statuses, and records consistent across services and tenants as data changes, using event-driven architecture.
- 04
Dashboard & reporting for financial data
We turn transaction and account data into dashboards and reports that finance teams and end users can query and trust.
- 05
Backend architecture for regulated-adjacent data
We structure backend systems, including multi-tenant environments, so sensitive financial data stays isolated, traceable, and ready for compliance work.
- 06
API integration with banking & payment providers
We integrate with banking APIs, card networks, and payment processors, handling authentication, rate limits, and error states.
02 — When
When companies come to us for fintech software
You need to add payments to an existing product. Your app already has users, and now you need to accept, move, or reconcile money without rebuilding the whole system.
You're building a financial dashboard or reporting tool. Raw transaction data needs to become something a finance team, an operator, or a customer can actually read and act on.
You need secure, real-time transaction data sync. Balances, statuses, and records have to stay consistent across services and tenants, with no dropped updates and no race conditions.
Your current fintech vendor can't move fast enough. You inherited a codebase or a stalled team, and you need engineers who can get inside an existing system and ship again.
04 — Process
Our fintech development process
- 01
Discovery & compliance-aware scoping
We map what the system needs to do, what data it touches, and what compliance requirements your legal or compliance team has already defined.
- 02
Architecture
We design the data model, service boundaries, and integration points before writing product code, with attention to how money and sensitive data move through the system.
- 03
Secure development practices
We build with encryption at rest and in transit, scoped access controls, and audit logging as defaults, not add-ons.
- 04
Integration with payment & banking APIs
We connect the product to the payment processors, banks, or financial data providers it needs, and handle the edge cases.
- 05
QA
We test transaction flows, data sync, and edge cases specifically, not just the happy path, since financial systems fail loudly when they fail.
- 06
Launch & support
We deploy, monitor, and stay available to fix and extend the system as your product and its data volume grow.

Frequently asked questions
Not yet. What we have is real experience with the underlying work: payment integrations, secure real-time data sync, and multi-tenant systems handling sensitive data.
