Every day in the underwriting queue costs the borrower their patience and costs you the deal. Manual credit reviews that could be automated, document requests that could be pre-filled from open banking data, and application portals that don't work on mobile, these aren't just UX problems. They're revenue problems.
Custom lending software is built around your products, your risk rules, and your borrower experience goals. Not a generic lending platform that treats every loan type the same.
The Mortgage Bankers Association puts the fully loaded cost to originate a single mortgage at more than $11,000 per loan (Mortgage Bankers Association, 2024), once you count staff time, compliance overhead, and rework on incomplete files. Manual workflows carry most of that cost. Every step you automate, document intake from open banking, credit and identity pulls, rules-based decisioning, takes a bite out of the per-loan number and the days-to-decision it drives.
Mortgage builds have their own requirements. Rate lock management so borrowers aren't left exposed between application and close. Pipeline dashboards for loan officers tracking multiple live files. Automated underwriting system (AUS) integration with Fannie Mae Desktop Underwriter and Freddie Mac Loan Product Advisor. Disclosure workflow automation that generates TRID-compliant Loan Estimates and Closing Disclosures within the 3-business-day window (US). In the UK, that means MCOB-compliant suitability assessments, MCD affordability calculations, and ESIS/KFI document generation. We build mortgage software to the regulatory requirements of your market, not to a generic origination template.
For the document processing automation that handles borrower document intake and verification, we scope that within the same engagement. For business process automation of compliance reporting and operational workflows, see our dedicated service.
Capabilities
What we build
01Loan origination systems
End-to-end application workflow from initial enquiry through to offer and acceptance, with configurable forms per loan product because consumer, SME, and mortgage flows collect different data and trigger different compliance checks. For mortgage: rate lock management, loan-officer pipeline dashboards, automated underwriting decisions, and appraisal ordering.
- Built with
- Fannie Mae DU · Freddie Mac LPA · AUS integration
02Underwriting automation
Credit decisioning engines that apply your risk rules automatically. Bureau data, open banking analysis, income verification, and fraud checks are pulled and assessed without manual intervention, with auto-approve, auto-decline, and refer workflows based on your thresholds.
Digital application portals that work on mobile and desktop, with document upload, real-time status updates, and post-funding account management. A borrower experience that matches what they expect from modern financial products.
- Built with
- OCR pre-fill
04Loan servicing platforms
Repayment tracking, arrears management, and settlement calculations, with automated payment collection via direct debit or open banking. Delinquency staging, dunning workflows, promise-to-pay tracking, hardship handling, and regulatory reporting: the operational backbone and collections engine for managing your loan book after origination.
05Credit bureau and data integration
Integration with credit bureaus, open banking platforms, income verification, identity verification, and fraud detection, with data pulled automatically at the point of application. Consent management and data retention are built to your regulatory requirements.
06Compliance and reporting
Responsible lending checks, affordability assessments, and disclosure workflows built in. For US mortgage: TRID disclosures, HMDA reporting, and Qualified Mortgage eligibility. For the UK: MCOB suitability, MCD affordability, and ESIS/KFI generation, with audit trails for every credit decision.
- Built with
- TRID · HMDA · QM · MCOB · ESIS/KFI
Why us
Why teams choose RaftLabs
01Senior engineers build what they scope
The engineers who assess your problem also build the solution. No bait-and-switch, no offshore handoff after the contract is signed. The team you meet in week 1 ships in week 12.
02Fixed price before development starts
We scope the work, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.
03Financial software shipped since 2015
Real engagements across SaaS, fintech, healthcare, and logistics, not every one published as a named case study. Track record across AI, SaaS, mobile, automation, and enterprise platforms in healthcare, fintech, logistics, and hospitality.
04Compliance built in from the start
SOC 2, GDPR, and the lending-specific regimes are scoped in week 1, not retrofitted before launch. That means TILA/Reg Z disclosures, ECOA/Reg B fair-lending logic and adverse-action notices, KYC/AML controls, FCRA-compliant credit pulls, and regulatory reporting are part of the architecture, not bolted on at the end.
01Loan product & compliance scoping
We start by documenting your loan products, your credit risk rules, and your regulatory obligations before designing anything. Consumer lending, SME lending, mortgage, BNPL, each has different decisioning logic, different compliance requirements, and different borrower experience expectations. The architecture follows from the product, not the other way around.
Loan product documentation: types, terms, eligibility criteria, risk tiers
Regulatory requirements mapping: responsible lending, KYC/AML, reporting obligations
Borrower journey mapping from application to disbursement and repayment
Fixed-cost scope for the first phase with milestone delivery dates
02Credit decisioning design
We design your credit decisioning engine before building it. Rules-based logic for auto-approve and auto-decline. Scoring model integration for risk-graded decisions. Referral routing for edge cases. Every decision logged with the supporting data so your compliance team can audit it and your risk team can improve the rules over time.
Decisioning rules design with your risk and compliance team
Scoring model integration architecture (bureau data, open banking, income verification)
Referral and underwriter queue design for out-of-rules applications
Audit trail architecture for every credit decision
03Platform build
We build in 2-week sprints. Origination, decisioning, borrower portal, and servicing modules are built in sequence against agreed specifications. Compliance controls are built alongside functional features, not added at the end. Your compliance team can review what's been built at each sprint, not just at launch.
2-week sprints with working platform demos at the end of each
Compliance controls built into each sprint, not deferred
Automated tests for business rules, decisioning logic, and regulatory workflows
Code review and integration tests as standard practice
04Integration & compliance testing
We connect the platform to credit bureaus, open banking APIs, identity verification services, and payment providers. Each integration is tested against real data before go-live. Compliance testing covers responsible lending checks, consent management, data retention rules, and regulatory reporting. Your compliance team signs off before launch.
Credit bureau, open banking, and identity verification integrations tested end-to-end
Responsible lending and affordability check validation
Regulatory reporting tested against your jurisdiction's requirements
Penetration test support and security review documentation
05Launch & regulatory review
We deploy to production and support your compliance team's pre-launch review. Documentation covers data flows, consent management, credit decision logic, and security controls in the format regulators and auditors expect. Post-launch monitoring covers decision rates, application volumes, system errors, and latency.
Production deployment with monitoring and alerting
Compliance documentation: data flow maps, decision audit trails, consent records
Regulatory reporting validation in production
Post-launch support plan and incident response process
