Fintech Software Development Company

Q: How much does fintech software development cost?

Custom fintech software development typically costs between $25,000 and $250,000 or more, depending on platform complexity, number of integrations, and compliance requirements. A focused payment tool or KYC workflow: $25,000–$60,000. A mid-complexity lending or insurance platform: $60,000–$120,000. A full neobanking platform with card issuance and multi-currency support: $120,000–$250,000+. The three biggest cost drivers are the number of financial integrations, the level of regulatory compliance required (PCI DSS, SOC 2, regional banking regulations), and whether the product needs real-time transaction processing. Contact us for a tailored estimate.

Q: How long does it take to build a fintech application?

A focused fintech tool takes 10–14 weeks. A mid-complexity platform takes 14–22 weeks. A full-scale neobanking or trading platform takes 22–30+ weeks. These timelines include discovery, design, development, security testing, compliance validation, and deployment. Compliance validation alone adds 3–4 weeks that non-financial software does not require.

Q: How do you ensure PCI DSS compliance in fintech development?

PCI DSS compliance is architected from day one, not added as a final step. Every system we build includes cardholder data tokenisation, field-level AES-256 encryption, network segmentation, role-based access control, immutable audit logging, and vulnerability scanning. We deploy on PCI DSS-eligible cloud infrastructure (AWS, Azure) and conduct a full penetration test before every go-live.

Q: Can you integrate with our existing banking or payment systems?

Yes. We build integration layers using open banking APIs, FIX protocol, ISO 20022, SWIFT messaging, and REST APIs to connect with core banking systems, payment networks, card issuers, KYC providers, and credit bureaus. Over 80% of our fintech clients start by extending their existing systems, not replacing them.

Q: What types of fintech businesses do you work with?

We work with neobanks, payment processors, lending platforms, InsurTech companies, wealth management firms, and financial SaaS products — from seed-stage startups to mid-market enterprises. Our best-fit clients are fintech companies that need custom-built, regulation-compliant platforms they fully own.

Q: Do we own the source code?

Yes, completely. All source code, design files, documentation, and intellectual property belong to you from Day 1. Full repository access is provided throughout the engagement. No lock-in, no exit penalties.

Q: How is Deorwine different from other fintech development companies?

We are a product engineering partner, not a body shop. We own delivery outcomes end-to-end — from regulatory discovery to go-live and post-launch compliance maintenance. We understand financial regulations (PCI DSS, SOC 2, KYC/AML, GDPR), not just code. Every project comes with defined KPIs benchmarked against your current operations and measured post-launch. We have delivered 30+ fintech and financial platforms across the USA, UK, UAE, Singapore, and India. The engineers who scope your project are the ones who build it.

Q: Do you work with fintech startups or only enterprises?

Both. For startups, we provide lean MVP builds with compliance foundations built in from the start, so your platform can scale without being rebuilt as you grow. For enterprises and regulated institutions, we handle complex legacy modernisation, multi-market compliance, and high-volume platform builds.

Q: Is my idea protected during the development process?

Yes. We sign a mutual Non-Disclosure Agreement before any discovery or scoping conversation begins. All project information, business logic, and proprietary financial models remain strictly confidential throughout and after the engagement.

We design and build PCI DSS, SOC 2, and KYC/AML-compliant fintech software for neobanks, payment processors, lending platforms, insurance companies, and trading systems. Every product is engineered for compliance, performance, and long-term scale with delivery outcomes we own end-to-end.

Fintech Software Development Consultation

Fintech software development consultation is the process of assessing your financial workflows, regulatory obligations (PCI DSS, SOC 2, KYC/AML), technology gaps, and security requirements — producing a compliance blueprint and delivery roadmap before a single line of code is written. A structured consultation typically takes 2–3 weeks and produces a platform specification covering regulatory obligations, tech stack, and integration architecture.

Deorwine's consultation process covers regulatory compliance audits (PCI DSS, SOC 2, GDPR, CBUAE, FCA), core banking integration planning, open banking API strategy, and technology stack selection. We give fintech businesses a clear, risk-free roadmap so you know exactly what you're building, what it will cost, and how long it will take.

Compliance Assessment

We map your product against PCI DSS, SOC 2, KYC/AML, and regional regulatory requirements before architecture decisions are made.

Workflow Discovery

We document your financial processes, transaction flows, user journeys, and operational pain points — identifying where technology can eliminate friction and cost.

Technology Roadmap

We recommend the right stack, API strategy, core banking integration path, and compliance tooling specific to your market and business model.
