Jack Henry provides financial technology software and services to community banks, regional banks, and credit unions. The company's primary offering is core processing software, which serves as the central operating system financial institutions use to process deposits, manage loans, execute transactions, and maintain account records. Jack Henry offers bank-focused core platforms including SilverLake, CIF 20/20, and Core Director, alongside its Symitar platform for credit unions. Beyond core processing, the company sells complementary products such as the Banno digital banking platform, payment processing across card and real-time payment networks, fraud detection tools, and treasury management solutions. Jack Henry operates across four segments: Payments, Complementary, Core, and Corporate Services. The company generates most of its revenue through recurring, multi-year contracts tied to account volumes and private cloud hosting, per-user SaaS subscriptions for digital tools, and transaction-based payment processing fees. Jack Henry sells its products through a direct sales force, cross-selling add-on capabilities to existing core clients while expanding modular solutions to third-party institutions.
