The problem
Building on a white-label banking platform that handles 80% of your product requirements but creates workarounds for the 20% that differentiates your offering from every other fintech using the same provider?
Compliance team spending days each month assembling KYC, AML transaction monitoring, and regulatory reporting data manually because the systems holding that data don't talk to each other?
The short answer
RaftLabs builds custom fintech software for financial institutions, fintech startups, and embedded finance businesses. We've shipped payment processing platforms, digital banking and neobank systems, loan origination and servicing software, wealth management platforms, KYC/AML compliance tools, and personal finance apps for 15+ fintech clients across the US, UK, and Australia. Most projects deliver in 10 to 16 weeks at a fixed, agreed cost.
Companies we've built for


White-label fintech platforms and banking-as-a-service providers have made it fast to launch a standard financial product. A lending product, a digital wallet, or a savings account can be live in weeks on the right BaaS platform.
The ceiling appears when your differentiation requires behavior the platform's configuration layer wasn't designed to support. A custom risk model the platform's underwriting engine can't express. A multi-currency account structure that doesn't fit the data model. A compliance workflow specific to a regulated market the platform only partially covers. At that point, the choice is between compromising the product or building what the platform can't deliver.
We've built payment processing systems, lending platforms, digital banking cores, wealth management tools, and KYC/AML compliance infrastructure for fintech and financial services businesses. The regulatory context is designed in from the first sprint: PSD2, FCA authorization, GDPR in financial services, and open banking standards. So are the technical specifics: double-entry accounting accuracy, idempotent payment processing, and audit trail requirements for regulated transactions. Nothing is retrofitted when a compliance review or a scaling problem forces the question.
Payment reconciliation done manually because the payment gateway and the ledger don't connect
Incoming payments, refunds, and failed transactions matched by hand each day is slow, error-prone, and gets worse as transaction volume grows. Left unaddressed, discrepancies sit undetected until end-of-day or end-of-month close, creating financial exposure and delaying reporting. An automated reconciliation system matches payment gateway events to ledger entries in real time, so your finance team catches discrepancies immediately rather than hunting for them hours later.
KYC and identity verification handled through a manual document review process
When onboarding requires a staff member to review identity documents and check PEP and sanctions lists by hand, the process becomes a bottleneck as application volume rises and a compliance gap when it doesn't. The cost of that gap is a regulatory breach, a failed audit, or a fraudulent account that passed because no one had time to look closely. Automated digital KYC with document verification, liveness checks, and real-time PEP/sanctions screening converts a multi-day manual process into a minutes-long automated one.
Loan underwriting decisions made from credit bureau data without an automated decision engine
When a credit analyst reviews each application manually, pulling bureau data and assessing affordability from bank statements, throughput is capped at the number of analysts you have. Decision inconsistency also increases credit risk: two analysts applying the same policy to the same file don't always reach the same outcome. An automated underwriting decision engine applies your credit policy consistently and cuts decision time from days to seconds for applications within your automated appetite.
Transaction monitoring for AML running on spreadsheet rules with no alert workflow
According to the Nilson Report (2024), global payment card fraud losses reached $33.83 billion in 2023, with the United States accounting for 42% of worldwide losses. When AML monitoring is a monthly spreadsheet exercise reviewing transactions above a threshold, coverage is limited and the review is always retrospective. By the time a suspicious pattern surfaces, the activity is weeks old and the regulatory obligation to file a SAR may already be overdue. A real-time transaction monitoring system with configured rules and an alert triage workflow gives your compliance team a manageable daily queue rather than a backlog they can't clear.
We integrate with Stripe, Adyen, Braintree, and direct acquiring networks, so you're not locked to a single gateway. Multi-currency transaction processing and FX management sit alongside reconciliation automation that matches payment events to ledger entries and flags discrepancies before end-of-day. Fraud detection rules and velocity controls reduce chargebacks. PCI DSS compliant data handling is built in from the start.
Built for fintech companies building payment products, businesses replacing manual reconciliation, and platforms embedding payments into a non-financial product.
Core account management with a double-entry ledger, transaction history, and balance calculation gives you the financial accuracy a regulated product requires. Current and savings account configuration, card program integration with issuance and controls, and open banking connectivity under PSD2 cover the product surface your customers expect. Digital KYC handles onboarding without a manual review queue.
Built for challenger banks and neobanks that have outgrown their BaaS platform, financial institutions building a digital-first product, and embedded finance businesses adding banking features.
Loan origination covers application intake, credit bureau integration, and an underwriting decision engine built to your credit policy, not a generic risk template. Loan servicing handles repayment scheduling, arrears management, early settlement, and collections workflows for delinquent accounts. Open banking affordability assessment replaces manual bank statement review. FCA-compliant documentation and portfolio reporting for funders are included.
Built for consumer and SME lenders replacing manual underwriting, BNPL platforms building a custom credit product, and specialist lenders whose credit model can't be configured in a standard system.
Portfolio management with multi-asset support, performance calculation, and rebalancing replaces the spreadsheet workflows that break under client volume. Robo-advisory covers risk profiling, model portfolio construction, and automated execution. Custody integration with brokers and custodians, FCA suitability and appropriateness assessment, and open banking account aggregation for a whole-of-wealth view round out the platform.
Built for wealth managers replacing legacy portfolio software, robo-advisory startups building a custom investment product, and platforms adding investment features to an existing financial services offering.
Digital KYC with document verification, liveness checks, and real-time PEP/sanctions screening replaces the manual review queue that slows onboarding. Transaction monitoring with configured rules and ML-powered alert generation gives your compliance team a daily triage queue instead of a spreadsheet of every transaction above a threshold. SAR workflow covers internal review, escalation, and NCA submission. Every compliance action is logged in a full audit trail so your next regulatory review has everything it needs.
Built for regulated businesses building compliance infrastructure, fintech companies that have outgrown manual KYC, and RegTech businesses building a compliance product.
Open banking account aggregation pulls transactions across multiple banks into a single view, so users don't have to piece together their finances manually. Transaction categorization with custom rules and merchant enrichment gives them accurate spending breakdowns. Budgeting tools with limits, alerts, and savings goals, credit score monitoring, and financial insights round out the product. Native iOS and Android apps with biometric authentication keep it secure.
Built for consumer fintech startups building a personal finance product, financial services companies adding money management to their proposition, and employers building a financial wellbeing benefit.

BaaS platforms accelerate launch and handle regulatory heavy lifting for standard financial products. Custom software becomes the right choice when the product requires behavior the platform's configuration layer can't support, when the platform's pricing becomes a constraint at the target transaction volume, when the compliance workflow requires jurisdiction-specific steps the platform doesn't handle, or when the fintech is building a product to sell to other financial institutions rather than use internally. The decision often comes at a specific transaction volume or product complexity threshold rather than at the start.
Yes. We understand FCA authorization categories, the Consumer Duty requirements that apply to regulated financial products, the operational resilience obligations for critical systems, and the GDPR requirements specific to financial data. We don't provide legal or compliance advice, but we build systems designed to meet the regulatory requirements your compliance team specifies. Compliance requirements are factored into the system architecture during discovery, not bolted on after go-live.
Financial data requires security measures beyond the standard web application baseline. That means PCI DSS compliance for payment card data, strong customer authentication under PSD2, encryption of financial records at rest and in transit, access controls limiting which systems and users can read specific financial data, and an audit trail of every access and modification to sensitive records. We design these controls into the architecture during discovery rather than adding them at the end. Penetration testing is facilitated before go-live.
A focused build, such as a payment reconciliation system or a digital KYC workflow, typically runs $30,000 to $65,000. A lending origination and servicing platform runs $50,000 to $100,000. A full fintech platform covering payments, accounts, compliance, and reporting runs $100,000 to $250,000 or more, depending on product complexity, the regulatory permissions required, and the number of third-party integrations. Fixed cost is agreed before development starts.
