Read articleFinTech & Payments
FinTech software development for teams building payment flows, financial dashboards and finance apps. We focus on secure code, clear audit trails and integrations that behave predictably.



Overview

FinTech software development has less room for error than most projects. Money moves, records must stay accurate and users expect their data to be protected. We design for that from the first sketch, with careful access control, clear logging and code that other developers can review and maintain.
We build payment integrations, customer dashboards, wallet and ledger style features, invoicing and reporting tools, and the web and mobile apps around them. We know how a real checkout, callback and refund flow behaves, because payment integration is part of our regular work.
Whether you need a custom web application or a mobile app, we start by agreeing which regulations and partner requirements apply to you. Your compliance advisers set those rules. We build to them and document what we build. We agree the technology with you after we understand your goals, users and budget. If you accept card payments, the PCI Security Standards Council explains the security rules that card brands expect merchants to follow.
Industry challenges
Financial data attracts attackers. Authentication, encryption, input handling and access rules all have to be designed in, not added later.
Every transaction and change needs a reliable record. Rounding, currency handling and retries must be handled with care.
Payment providers, banks and data services each have their own rules, limits and failure modes that the software must cope with.
Requirements differ by country and product. The software has to support the checks and records that your advisers and partners ask for.

What we build
Checkout, callback, refund and reconciliation flows for the gateways your customers use, built with clear error handling.
Balances, top ups, transfers and transaction history with consistent records behind every movement.
Clear views of balances, transactions and trends for customers or for your own team.
Invoices, recurring billing, reminders and statements connected to your accounting tools.
iOS and Android apps for payments, tracking and account management that share logic with your web platform.
Secure APIs and connectors to banks, accounting software and data providers.
