A Complete Banking Infrastructure Platform Built for Scale

From accounts and payments to lending and compliance, SiteTwin provides every building block you need to create world-class financial products — all through a single, unified platform.

Ledger & Account Management

Our double-entry ledger engine supports unlimited account hierarchies, multi-currency balances, and real-time reconciliation. Create checking accounts, savings accounts, virtual cards, and custom account types with configurable rules for interest accrual, fees, and limits. The ledger processes thousands of entries per second with guaranteed ACID compliance, ensuring your financial data is always accurate and auditable.

Payment Processing & Transfers

Connect to ACH, wire transfers, SEPA, Faster Payments, and card networks through a single integration point. SiteTwin handles payment routing, retry logic, and settlement automatically. Support real-time payments, scheduled transfers, batch processing, and recurring billing — all with built-in fraud screening and transaction monitoring to protect your customers and your business.

KYC & Identity Verification

Onboard customers in minutes with our intelligent identity verification pipeline. SiteTwin orchestrates document verification, biometric checks, watchlist screening, and risk scoring across multiple data providers. Our adaptive verification flows adjust requirements based on risk level, reducing friction for low-risk customers while maintaining rigorous checks for higher-risk scenarios. Full audit trails ensure regulatory compliance.

Lending & Credit Decisioning

Launch lending products with our configurable credit engine. Define custom scoring models, set underwriting rules, and automate loan origination, servicing, and collections. SiteTwin supports consumer loans, lines of credit, buy-now-pay-later, and invoice financing. Real-time credit bureau integrations and alternative data sources help you make smarter lending decisions while managing portfolio risk effectively.

Multi-Currency & FX Engine

Serve global customers with accounts that hold balances in 50+ currencies. Our FX engine provides competitive real-time exchange rates, transparent fee structures, and automated currency conversion. Whether your customers need to send international remittances, receive payments in foreign currencies, or manage multi-currency treasuries, SiteTwin makes cross-border finance simple and cost-effective.

Developer Tools & Documentation

Get up and running fast with comprehensive API documentation, interactive sandbox environments, SDKs in Python, Node.js, Ruby, and Go, plus pre-built UI components. Our developer portal includes step-by-step guides, code samples, and webhook testing tools. Dedicated developer support engineers are available to help you architect solutions and troubleshoot integrations at every stage of your build.

Why Leading Fintechs and Banks Choose SiteTwin as Their Infrastructure Partner

Building financial products from scratch is extraordinarily complex. Between integrating with payment networks, navigating regulatory requirements across multiple jurisdictions, implementing robust security measures, and maintaining the reliability that financial services demand, the engineering burden can be overwhelming. This is precisely why forward-thinking companies choose SiteTwin. Our platform abstracts away the undifferentiated heavy lifting of banking infrastructure, allowing your team to focus on what truly matters: creating exceptional customer experiences and innovative financial products that set you apart from the competition. Instead of spending 18 months and millions of dollars building core banking systems, you can launch your first product in as little as 6 weeks. SiteTwin is not just a collection of APIs — it's a cohesive, battle-tested platform that has been refined through years of real-world usage by hundreds of companies. Every module is designed to work seamlessly together, from account creation through payment processing, compliance monitoring, and reporting. This integrated approach eliminates the integration headaches and data silos that plague companies stitching together point solutions from multiple vendors. Our customers range from early-stage startups launching their first financial product to publicly traded companies processing billions in annual transaction volume. What they all share is a commitment to moving fast without compromising on security, compliance, or reliability. SiteTwin makes that possible by providing infrastructure that scales automatically, stays compliant with evolving regulations, and maintains the 99.99% uptime that financial services demand. We also believe in transparency. Our pricing is straightforward with no hidden fees, our documentation is comprehensive and always up-to-date, and our support team is staffed by engineers who understand both the technology and the regulatory landscape. When you partner with SiteTwin, you gain more than a vendor — you gain a strategic ally in your mission to transform financial services.

Our streamlined onboarding process is designed to get you building and shipping financial products as quickly as possible, with expert guidance at every stage.
