+44 203 507 0033Finance and Insurance Software Development Company
The worst time to discover your financial software cannot handle regulatory scrutiny is when the regulator is already in the building. We build custom financial software for banks, fintechs, and financial services businesses where compliance is designed into the architecture from sprint one, not bolted on after the first audit finding.
Eighteen years building in one of the most unforgiving software environments that exists. We start every engagement with what your FCA permissions, your product obligations, and your customer commitments actually require.

Reasons financial services software projects fail
before they reach the user
Compliance is treated as a project phase rather than an architectural requirement
The most expensive mistake in financial software development is building the product first and mapping the regulatory obligations afterwards. FCA, PRA, MiFID II, PSD2, and the relevant SEC or FINRA frameworks do not describe features you add to a financial platform. They describe how the platform must behave at a structural level. We build regulatory compliance into the architecture of every custom finance software engagement from the first sprint.
ChannelPorts NCTS5 cut declaration error rates by 15% and processing times by 30%.
Your critical financial systems run on legacy core infrastructure
The bank or insurer running on a 1990s core system is not running it because the technology is good. It is running it because every failed attempt to replace it has reinforced the perception that the cost of change outweighs the cost of staying. Custom banking software development does not always require replacing the core. We build modern API layers, microservices architectures, and financial software integration platforms that connect legacy infrastructure to modern financial products without the risk of a full core replacement.
Your customer-facing financial products are constrained by what the vendor platform allows
Your product team has a clear view of the customer experience they want to deliver. Your vendor platform has a clear view of what it supports. The gap between those two positions is where financial services businesses lose competitive ground to newer entrants who built their fintech software development platforms from scratch around the specific product they wanted to offer. Custom fintech software development removes that constraint entirely.
Your operational data lives across disconnected systems
Your transaction data, your compliance records, your customer data, and your risk management information sit in separate systems that were never designed to produce a coherent operational picture. Your team reconciles them manually every month close. We build financial services software that connects your operational data end-to-end so your risk, compliance, and finance functions work from one live, accurate source.
EPIC Global Solutions improved operational efficiency by 33% and scalability by 29%.
Financial services software built for the wrong environment
costs more than it saves
Most financial services businesses are not short of software. They are running too much of it, none of it talking to anything else, all of it accumulating compliance obligations the original vendor never anticipated. The global fintech market was valued at $394.88 billion in 2025 and is projected to reach $1,760.18 billion by 2034 at a CAGR of 18.20%. That growth is not coming from financial institutions configuring more generic platforms. It is coming from organisations that built custom financial software development solutions around how their specific financial products work, how their customers use them, and what their regulators require.
The regulatory dimension changes everything in financial services. BFSI software development that does not start with your FCA, PRA, or SEC obligations from the first sprint will produce software that technically functions and commercially underperforms. Compliance is not a feature you add to a financial platform. It is an architectural decision that shapes how your data is stored, how your transactions are processed, how your audit trail is maintained, and how your system behaves when something goes wrong.
Geeks delivers financial software development services for financial institutions, fintech businesses, and financial services companies that have outgrown what a standard platform can provide. Search Acumen, a property data and search business serving law firms and conveyancers, came to us needing AI-powered automation for high-volume financial communications. We built Robbie, a model that now processes over 95% of incoming emails automatically, reduced manual workload by 87%, and contributed directly to a successful acquisition. That is what financial technology software development looks like when it starts with the business problem rather than the technology stack.

How we build financial software development services that
operate correctly in regulated environments
Every finance software development project starts the same way. We map your regulatory obligations and your product model before we design anything.
Regulatory and product discovery
- We spend structured time with your compliance, technology, product, and operations stakeholders to map the regulatory framework your business operates under, the financial products you offer, and the operational workflows those products generate.
- We review your existing financial services software environment, your data architecture, and your integration landscape before making any design or technology recommendations.
Architecture and compliance design
- We design your custom financial software architecture around your specific regulatory requirements, your product model, and your data security obligations using our proprietary wireframing tool VisualSpec.
- Your compliance, technology, and product leads review every workflow and data flow before development begins, not after the system is built.
Agile development with regulatory checkpoints
- We build in two-week sprints with structured compliance review checkpoints built into every cycle so your compliance team tests against real regulatory scenarios throughout the build rather than at the end of it.
- We handle all integrations with your core banking systems, payment rails, regulatory reporting platforms, and any other financial infrastructure your business depends on.
Security and compliance testing
- Every financial software development platform is subject to structured security testing, penetration testing, and compliance validation before it goes near a live financial environment. Financial services software has a higher security and audit trail standard than most other software categories, and we test accordingly.
- We produce the compliance documentation and audit evidence your FCA, PRA, or SEC relationship requires as a structured deliverable within the development process rather than assembling it retrospectively.
Go-live and regulatory notification
- We plan go-live around your regulatory calendar and your operational risk appetite. Switching live financial systems at month-end, during a regulatory reporting window, or during peak transaction volumes creates risk that structured transition planning manages.
- Where your platform change requires FCA or PRA notification, we support your compliance team with the technical evidence and change documentation the notification process requires.
Ongoing development within regulatory constraints
- Financial regulation changes. Consumer Duty, Basel IV, AI Act, and the continuing evolution of open banking standards all create software obligations that did not exist when your platform was first built.
- We maintain and develop the financial technology software development platforms we build as the regulatory and commercial environment evolves, treating every regulatory change as a development requirement rather than a compliance problem.

Finance and Insurance Software Development FAQs
Finance software development is the design and build of custom software for financial services businesses operating in regulated environments. This includes banking software development, payment software development, wealth management platforms, insurance systems, compliance automation tools, and fintech software development for startups building new financial products. Custom financial software solutions are built around your specific regulatory obligations, your product model, and your operational requirements rather than configured from a generic platform.
We build against FCA and PRA requirements for UK-regulated financial services businesses, including Consumer Duty, MiFID II, PSD2, AML, and KYC obligations. For US-market financial software, we build against SEC, FINRA, and FinCEN requirements as applicable to your specific product type and licence. PCI-DSS compliance is a standard requirement for every payment software development engagement. GDPR and UK GDPR data protection requirements apply across all engagements.
Yes. Custom banking software development does not always require replacing the core. We build modern API layers, microservices architectures, and middleware platforms that connect your existing core banking infrastructure to new digital products and customer-facing systems. This approach allows you to modernize your customer experience and your operational capabilities without the cost and risk of a full core replacement programme.
Yes. AI is embedded across a significant proportion of the financial software development work we deliver. We build AI for fraud detection, credit scoring, AML transaction monitoring, and customer communication automation. Every AI capability we build for a regulated financial services context is developed with the FCA's guidance on AI in financial services in mind, including explainability requirements for credit decisioning and the fairness obligations that apply to AI-driven customer outcomes.
Yes. Our fintech development services span the full spectrum from established banks modernizing legacy systems to fintech startups building their first regulated product. For startups, we work from initial concept through to production-ready software including architecture, regulatory infrastructure, and go-live support. We understand that a fintech startup building under an EMI licence or a banking licence faces a different set of development constraints to an incumbent institution, and we design accordingly.
An off-the-shelf financial services software platform is built for the broadest possible range of financial services use cases. Custom fintech platform development is built entirely around your specific product, your specific customer base, and your specific regulatory permissions. The commercial advantage compounds over time. A custom platform can be extended as your product evolves without being constrained by what a vendor roadmap supports or what a generic platform charges for additional capability.
Data security in financial software development is an architectural requirement, not a feature. Every engagement is built against ISO 27001, OWASP security standards, Cyber Essentials, and the specific data security obligations applicable to your financial services licence. We conduct penetration testing, vulnerability assessments, and security code reviews as structured workstreams within every engagement. Production environments are designed with disaster recovery, incident response, and security monitoring built in from the start.
Yes. Accounting software development for financial services businesses carries different requirements to standard business accounting software. Financial instrument accounting, regulatory capital calculation, multi-currency consolidation, and the specific chart of accounts structures applicable to regulated financial entities all require domain knowledge that generic accounting software vendors do not apply. We build custom financial accounting systems around the specific accounting framework applicable to your entity type and jurisdiction.
Timeline depends on scope, complexity, and regulatory certification requirements. A focused fintech development services project covering a specific financial product or workflow can be delivered in months. A full financial technology software development engagement covering a regulated banking product, open banking integrations, KYC onboarding, and AML monitoring takes considerably longer. Every project is scoped in detail before development begins so you have a clear timeline and cost from the start.
We start with a conversation about your business, your regulatory position, your current systems, and what you are trying to build or improve. From there we conduct a structured discovery and produce a detailed proposal covering scope, regulatory approach, architecture, timeline, and cost. No commitment is required for that initial conversation. Book directly at geeks.ltd/book-a-meeting.
There is no fixed price. Cost is shaped by regulatory compliance requirements, workflow complexity, and how many existing systems need to connect to your new platform. Security architecture, audit trails, and data residency rules all add layers that generic estimates cannot account for. Get a quote from here.
