Corefy is a payment orchestration and white-label infrastructure platform built for payment institutions, PSPs, fintech companies, online platforms, and large merchants that operate complex payment setups. The platform helps businesses manage their entire payment ecosystem through a single system. It brings together payment and payout processing, routing and cascading logic, analytics, tokenisation, anti-fraud controls, and operational tools into one configurable infrastructure layer. Instead of maintaining numerous direct integrations with different providers, companies can connect to Corefy and access a network of more than 600 ready-to-use connectors with global PSPs, acquirers, and alternative payment providers. A key capability of the platform is its advanced routing and cascading engine powered by over 100 configurable attributes, including metadata. Businesses can define detailed rules that determine how transactions are distributed across providers based on parameters such as geography, BIN, currency, performance indicators, or risk signals. This flexibility allows teams to optimise approval rates, balance payment traffic, and improve operational stability without rebuilding their infrastructure. Corefy also supports organisations launching their own payment products through white-label capabilities. The platform includes tools for merchant account hierarchy management, role-based permissions, reporting, and operational oversight. For companies that already operate payment infrastructure but want to expand their connectivity, Corefy offers Payment bridge — a solution that enables fast deployment of new payment integrations without complex system migrations. Corefy’s infrastructure has processed over 1 billion transactions and supports payment providers and digital businesses worldwide.
