What we build
Services for FinTech and Finance.
Custom engineering for fintech firms, payment platforms, lending operations, and finance-adjacent B2B businesses where security posture and audit trails matter.
Financial software development
Custom banking platforms, loan origination software, investment management tools, and the back-office workflows finance operations actually use.
Payment & transaction solutions
Digital wallets, P2P payment systems, subscription billing, and the integration plumbing payment platforms run on. Custom payment plugin work pattern from accept.blue.
Lending & mortgage software
Credit risk analysis, mortgage underwriting workflows, BNPL (buy-now-pay-later) offerings, and the documentation lenders need for state-specific compliance.
InsurTech (Insurance Technology)
AI-powered claim processing, policy management, fraud detection, and customer-facing insurance platform engineering.
Audit-grade logging & controls
Append-only audit trails, segregation of duties, change tracking, and the documentation finance compliance teams expect for SOX, SOC 2, and internal audit.
Adjacent OST experience
Fintech work sits inside OST's broader e-commerce and B2B practice.
accept.blue is on our E-commerce vertical page (B2B fintech, OpenCart plugin engineering). For the full e-commerce capability set including custom payment plugin work for Fire Mountain Solar and 12+ OpenCart engagements, see the E-commerce page. For B2B platform engineering depth, see Manufacturing/Industrial.
FinTech-sector compliance
Frameworks fintech clients ask about.
Scope determined per engagement based on what your platform handles and your jurisdictional reach. OST does not provide direct compliance certification but assists with integrations and best practices. See the Trust Center for the broader posture.
PCI DSS (assisted)
Tokenization through compliant processors, vault integration, and architecture choices that minimize cardholder data scope. Implementation assistance rather than blanket PCI certification.
SOC 2 / ISO 27001 readiness
Security controls, access management, audit logging, and the documentation a SOC 2 auditor accepts. We build platforms that can pass when you formalize the audit.
GLBA & state financial privacy
Gramm-Leach-Bliley Act, state financial privacy laws, and consumer financial data protections scoped per the geographies your platform serves.
GDPR (assisted)
EU and UK data protection. Data processing agreements, cross-border transfer mechanisms, and right-to-erasure workflows. Implementation assistance scoped per engagement.
