What We Build for Banks, Payment Providers, and Fintech Platforms

Fintech buyers rarely need one thing. Most engagements touch two or three of these categories at once, and each one carries its own compliance surface, so we scope and staff them accordingly rather than treating a lending build the same way we'd treat a wallet.

Core Banking & Ledger Systems

We build double-entry ledger cores, account management layers, and transaction processing engines that reconcile in real time, not on a nightly batch job that leaves your support team guessing until morning.

Payment Gateway & Rails Integration

Multi-currency payment processing, ACH and SEPA Instant connectivity, and card network integration, built with tokenization instead of raw PAN storage so your PCI scope stays as small as the architecture allows.

Digital Wallets & P2P Transfers

Custodial and non-custodial wallet infrastructure with real-time balance sync, split payments, and fraud checks that run before a transfer clears instead of flagging it after the money has already moved.

Lending & Credit Decisioning Platforms

Loan origination workflows, underwriting engines, and credit decisioning logic that can explain a rejection, which matters more every year as regulators push explainability requirements into automated lending decisions.

Wealth & Investment Management Tools

Portfolio tracking, robo-advisory logic, and trading interfaces built to handle real-time market data feeds without the UI lagging behind the number that actually matters to the user watching it.

Insurance & InsurTech Platforms

Policy administration, claims processing automation, and underwriting rules engines that connect cleanly to the actuarial models your team already trusts instead of forcing a rebuild around ours.

Trading & Exchange Systems

Order matching engines, market data pipelines, and institutional-grade trading interfaces built for the latency and audit trail requirements that separate a demo from a production trading platform.

Compliance & RegTech Tooling

KYC and AML workflow automation, transaction monitoring dashboards, and audit trail systems designed so your compliance team can pull evidence in minutes instead of reconstructing it during an examination.

Why Generic Development Teams Struggle With Fintech Builds

Most software agencies can ship a working app. Fewer can ship one that survives a SOC 2 audit, a payment network security review, and a regulator’s questions about where customer data actually lives. The gap shows up late, usually right before launch, when a generic build has to be partially rearchitected to pass a review nobody scoped for at the start.

Fintech development isn’t harder because the code is harder. It’s harder because every architectural choice, where data sits, how a service authenticates, what gets logged, doubles as a compliance decision. Treating those as afterthoughts is how a six-month build becomes a nine-month one.

What Changes When Your Outsourcing Partner Becomes an ICT Third Party

Under DORA, once you outsource fintech development, your vendor doesn't sit outside your regulatory perimeter. It becomes an ICT third-party provider, and you remain fully accountable for what that vendor builds and how it's documented. That means your contract needs specific clauses around audit rights, subcontracting controls, and incident notification, and you need a Register of Information that names the vendor and describes what they touch. Not a paperwork exercise. It changes how a vendor should be selected in the first place, because a partner who can't produce audit-ready documentation on request becomes your compliance gap during the next examination, not theirs. How we structure engagements around this:

Audit Trail Documentation by Default

Every engagement produces the change logs, access records, and decision documentation a Register of Information entry actually requires, generated as part of delivery rather than assembled after the fact.

Senior Engineers Only, No Mid-Build Swaps

The team assigned at kickoff is the team that delivers. Swapping juniors in after signing is one of the most common vendor risk findings we’ve seen clients flag from prior partners.

Exit and Transition Terms Defined Upfront

Source code, documentation, and infrastructure access transfer cleanly if you bring development in-house later, with the transition plan agreed before the engagement starts, not negotiated during an exit.

Subcontracting Disclosed, Not Discovered

If any part of delivery touches a subcontractor, that’s stated in the contract. Regulators increasingly ask about fourth-party risk, and an undisclosed subcontractor is a finding waiting to happen.

Fintech Compliance Standards We Build Against

Compliance claims are easy to print on a homepage. What actually matters is whether the architecture holds up when a payment network, an auditor, or a regulator asks to see the evidence. Every fintech engagement is built against the current version of the relevant standard, not whatever was current when the last project shipped, and the documentation to prove it is part of delivery, not a separate deliverable billed later.

PCI DSS 4.0.1 controls enforced in CI/CD pipelines
SOC 2 Type II-ready infrastructure and logging
DORA-aligned ICT risk and incident documentation
GDPR data residency and access controls
Tokenized payment data, never raw PAN storage

Built for the Specific Sector You Operate In

Banking, payments, lending, and wealth management don't share a compliance profile even though they all fall under "fintech." A lending platform's biggest exposure is explainability in credit decisions. A payments platform's biggest exposure is cardholder data scope. We scope each build around what actually applies to that sector instead of applying one generic compliance layer to everything.

Banking & NBFCs

Core banking modernization, digital-first account opening, and ledger systems built for institutions moving off legacy cores without a multi-year migration freeze.

How a Fintech Engagement Is Actually Staffed and Governed

Most outsourcing problems trace back to unclear ownership rather than weak engineering. Before a line of code is written, we define who decides what, how architecture changes get approved, and how often you'll see working software instead of a status deck. That structure is what makes a distributed team behave like an extension of yours instead of a black box you're checking in on.

Decision Ownership Defined

Architecture, security, and delivery decisions each have a named owner on both sides before kickoff, so a scope question doesn’t sit unanswered for a week while someone figures out who’s supposed to answer it.

Weekly Working Demos

You see working software every week, not a slide summarizing what was supposed to happen. If something’s behind, you find out from the demo, not from a retrospective three sprints later.

NDA and Code Ownership

Every engagement starts under an NDA, and full source code ownership transfers to you at delivery. That’s the baseline, not a negotiated add-on.

What Your Fintech Platform Actually Has to Connect To

Core Banking Integration

Connects to legacy and modern core banking systems through existing API layers or custom middleware where the core doesn't expose one cleanly.

Real-time balance and transaction sync
Legacy core API wrapping where needed
Dual-write reconciliation during migration windows

Outcome:

no forced core replacement just to ship a new feature

Payment Rail Connectivity

Built for ACH, SEPA Instant, and card network connectivity, with an eye on the SWIFT ISO 20022 structured-address migration landing in November 2026.

ACH and SEPA Instant integration
Card network tokenization support
ISO 20022 message format readiness

Outcome:

payment infrastructure that doesn't need a rebuild for the next mandate

KYC & AML Tooling

Connects to identity verification and transaction monitoring vendors rather than building screening logic from scratch, which shortens both build time and audit prep.

Identity verification API integration
Real-time transaction monitoring hooks
Case management workflow automation

Outcome:

AML coverage that's provable, not just claimed

Data & Analytics Pipelines

Structured data pipelines feed reporting, fraud models, and regulatory filings from the same source instead of three disconnected exports that never quite agree with each other.

Real-time and batch pipeline options
Fraud model feature pipelines
Regulatory reporting data feeds

Outcome:

one source of truth for numbers that get audited

FINTECH ENGAGEMENT TIERS

Choose the Right Engagemnt Model

Most fintech builds fall into one of three cost bands depending on compliance scope and integration complexity. Here's how projects typically break down.

MVP Validation

$15,000 – $35,000 Best for testing a lending, payments, or wallet concept before committing to a full build

Core feature set only
Single compliance regime (typically PCI DSS or GDPR)
6-12 week typical timeline

POPULAR

Core Platform Build

$35,000 – $70,000 Best for a production-ready platform serving real customers under active regulatory scrutiny

Full feature set with integrations
Multi-standard compliance (PCI DSS, SOC 2, GDPR)
4-7 month typical timeline

Enterprise & Multi-Region Platform

$70,000 – $200,000+ Best for regulated institutions operating across multiple jurisdictions

Custom architecture, multi-region data residency
DORA, PSD3, regional regulator alignment
Ongoing engagement, not a fixed end date

FINTECH ENGAGEMENT PROCESS

How a Fintech Engagement Actually Runs

Every engagement follows the same disciplined path, whether the outcome is an AI system, a custom platform, or a cloud migration. No surprises, no shortcuts.

Scope & Map

We define what's in scope, which regulations apply, and who owns which decisions before any architecture work starts.

Architect

Data flow, access control, and integration points get designed against the standards identified in scoping, not retrofitted later.

Build & Test

Development runs in sprints with weekly demos, security testing built into the pipeline rather than scheduled as a final gate.

Deliver & Document

Handover includes source code, architecture documentation, and the audit trail evidence your compliance team will eventually need to produce.

What to Keep In-House and What to Outsource

Not every part of a fintech build belongs outside your walls. This is roughly how the decision plays out in practice.

Function	Keep In-House	Outsource Candidate	Why
Core risk logic and pricing models	Yes	No	Proprietary IP that defines competitive advantage
Payment gateway integration	No	Yes	Well-understood, repeatable, execution-heavy
Compliance strategy and interpretation	Yes	No	Requires ongoing regulatory judgment, not a one-time build
KYC/AML tooling integration	No	Yes	Vendor integration work, not proprietary logic
Core banking ledger architecture	Shared	Shared	High-stakes design decisions need internal ownership with outsourced execution capacity
Mobile and web application development	No	Yes	High execution intensity, low strategic differentiation
Fraud model feature engineering	Shared	Shared	Model strategy stays internal, pipeline build can be outsourced

Insights & Trends

Why Fintech Teams Choose Citrusbug for Outsourced Development

Vendor Risk Ready

Engagements produce the audit trail and documentation your Register of Information entry needs, without a separate request or added fee.

Senior Engineers Only

The engineers assigned at kickoff deliver the project. No mid-build swaps to junior staff after the contract is signed.

Secure by Architecture

Security and compliance controls are designed into the architecture from the first sprint through our Secure ADLC methodology, not added before launch.

Stalled Project Recovery

We take over fintech builds of a previous vendor left unfinished or under-documented and get them to a compliant, working state.

Fixed-Price or Flexible Models

Fixed-Price, Time and Material, and Dedicated Team engagement options, matched to how much your scope is likely to shift.

Full Ownership at Delivery

Source code, documentation, and infrastructure access transfer completely at handover. Nothing stays locked to us.

Frequently Asked Questions

What parts of fintech development should never be outsourced?

Core risk logic, proprietary pricing models, and compliance strategy should stay internal. Execution-heavy work like integrations and application development is a strong outsourcing candidate.

How do you handle compliance when we outsource core banking or payments development?

Compliance requirements are mapped during scoping, before architecture starts, and the resulting documentation satisfies PCI DSS, SOC 2, and DORA evidence requirements simultaneously where they overlap.

Who owns the source code and IP after the engagement ends?

You do. Full source code and IP ownership transfer at delivery under NDA, with no licensing or usage restrictions afterward.

What happens under DORA if you're our ICT third-party provider?

We provide the audit rights, incident notification terms, and documentation your Register of Information entry requires. You retain full regulatory accountability, and we support the evidence trail that accountability needs.

Can you take over a fintech project a previous vendor stalled or left unfinished?

Yes. We assess the existing codebase and documentation first, then scope a path to a compliant, working state rather than assuming a full rebuild is necessary.

How do you staff a fintech engagement, and can we see who's assigned before signing?

Yes. Senior engineers are named before kickoff, and that team delivers the project without being swapped for junior staff mid-build.

What's the realistic timeline for a compliant MVP versus a full platform?

MVPs typically run 6-12 weeks. Core platforms with multi-standard compliance typically run 4-7 months, depending on integration complexity.

How do you handle data residency for EU or multi-region fintech clients?

Data residency requirements are defined during scoping and built into the architecture, including regional data storage boundaries required under GDPR and DORA.

What does the exit or transition plan look like if we bring development in-house later?

Exit and transition terms are agreed before the engagement starts, covering code transfer, documentation handover, and knowledge transfer sessions with your incoming team.
