Fintech Software Development Services
We build custom banking software, payment processing systems and regulatory-compliant fintech platforms for banks, neobanks, payment providers and lending companies. Full-cycle custom fintech software development, from architecture to launch, with KYC/AML, PCI DSS and GDPR compliance built in from day one.
Here’s what teams get when they work with a fintech software development company that treats compliance and architecture as one job instead of two:
for MVP fintech products when core banking, payments and compliance are architected together instead of stitched from separate vendors
built into the architecture from day one — not retrofitted before a security audit
typical time to a working fintech MVP
across live projects — PayPal, Stripe, Plaid, Railz, Yodlee and more
What’s built into a Dotcode fintech platform
Every fintech software development services engagement at Dotcode is scoped against the compliance standards and payment rails that apply to your market. KYC, AML, PCI DSS and core banking architecture is defined before the first sprint, not added before an audit.
Built to satisfy the regulators your users answer to — from KYC and AML checks to PCI DSS, GDPR and SEC-level reporting.
Support channels your users actually reach for, wired into the same platform as your core banking data.
The operational backbone — accounts, transactions, deposits and lending — all on one system of record.
Card and wallet rails your users already trust, ready to plug into your product.
A fintech product rarely stands alone — as a fintech software development agency, we connect it to the payment rails and banking APIs your users and regulators expect.
Security that holds up when an auditor starts asking hard questions about your fintech software development services partner, not just when nobody’s looking.
Fintech companies we build software for
From an early-stage neobank shipping its first MVP to a payment platform processing millions of transactions — the development model adapts to where you are.
As a fintech software development firm, we’ve shipped platforms across most corners of financial services. A few examples of who we typically build for:
Core banking modernization, multi-channel banking and CRM integration for institutions moving off legacy systems.
Full-stack digital banking platforms built for speed-to-market without cutting compliance corners.
Payment gateway integration, multi-currency processing and fraud detection for high transaction volumes.
Loan origination, credit scoring and repayment management built around your underwriting model — the same fintech software development services stack whether you’re scoring consumer loans or commercial credit.
Portfolio management, robo-advisory and trading infrastructure with SEC-aware architecture. This is custom fintech software development for platforms that can’t afford to get compliance wrong.
Trading platforms and blockchain integrations with the same compliance discipline as traditional finance.
Account management, transaction processing, deposits and multi-channel banking on architecture that scales with volume.
PayPal, Stripe, MangoPay, Railz, Plaid and card-scheme integrations wired into one reconciled flow.
Full-stack mobile-first banking experiences, from onboarding to card issuing.
KYC, AML transaction monitoring and audit-ready reporting built into the platform — software development for fintech that treats compliance as core architecture, not a bolt-on.
Loan origination, credit scoring and repayment management built around your underwriting model, delivered as one fintech software development service instead of a patchwork of vendors.
Bespoke platforms for what off-the-shelf tools don’t cover — built, owned and supported end to end. This is custom fintech software development in the fullest sense: nothing licensed, nothing you don’t control.
Custom fintech software vs banking-as-a-service platforms

Platform-level only
Configured for your license & jurisdiction
Extra fees per tier
Built for growth from day one
Vendor lock-in
100% yours from day one
One-size-fits-all rules
Tuned to your risk model
The financial market's gone digital — paperless workflows, AI-driven decisioning, automation replacing manual review. As a fintech software development company, we help you build for where the industry's heading, not where it was five years ago.
Compliance frameworks shift by jurisdiction and by year. Our software development for fintech bakes in the standards regulators actually check for, so a rule change doesn't mean rebuilding your platform.
From the first architecture diagram to a live production deploy, we stay the same fintech software development firm throughout — no handoffs between teams who've never talked to each other.
Transaction volumes spike; your architecture shouldn't. We build for scale from the start, so this fintech software development service keeps performing at 10x your current volume, not just today's.
We take care of that through smart development that saves your resources, not just reducing prices.
Our post-payment work format eliminates risks for your side.
dotcode keeps track of time and tasks with a reliable time and task tracking system to maintain full visibility.
We’re always here for our clients and keep all lines of communication readily open
No copy-pasting, our original code is yours, stored on your GitHub, and protected by a signed NDA
We adopt an Agile approach for quick and successful project completion
Our expertise in Fintech industry
An AI-driven trading engine built for a crypto platform handling live market data and automated execution. The architecture had to process pricing signals in near real time while keeping the same compliance discipline you’d expect from a regulated exchange, not a side project.
It covers core banking systems, payment gateway integration, digital banking platforms, lending and credit scoring engines, RegTech and compliance reporting, and fraud detection. Most projects use a mix of these depending on what you’re building — a neobank MVP might start with onboarding, a debit card and one payment rail, while a lending platform leans harder on credit scoring and repayment logic from day one. Get project estimate.
Cost depends on scope — a lending MVP with one payment integration costs a lot less than a full digital bank with card issuing, multi-currency support and a compliance dashboard. Team size, integration count and how many jurisdictions you need to cover all move the number. The fastest way to get a real figure is a project-specific estimate rather than a rule of thumb.

PayPal, Stripe, Square, MangoPay, Plaid, Railz, Yodlee, TrueLayer, and card schemes including Visa, Mastercard and American Express, plus identity verification through Jumio, Onfido and Veriff. If your stack uses something else, tell us — we’ll scope the integration rather than force you onto a provider we already know.
Yes. Compliance isn’t an add-on step at the end — KYC, AML and PCI DSS requirements get built into the architecture from the first sprint, not patched in before an audit. That’s usually the difference between a launch that goes smoothly and one that stalls at the compliance review.
Regularly. As a fintech software development provider working with early-stage teams, we know the tradeoffs between shipping fast and building something that survives a regulator’s review — and we build for both.
Yes — including AI-driven trading infrastructure. Our Bedrock case study shows what that looks like in production. View Bedrock case study.
A working MVP usually takes 6–10 weeks. Full custom fintech software development services for a production platform with multiple integrations run longer — the fastest way to get a real timeline is to scope your specific project. Get project estimate.
Tell us about your project — we'll scope the compliance requirements, map the payment integrations, and show you what 6–10 weeks to a working version looks like.
