TRANSFORMING FINANCIAL DATA WORKFLOWS: SERVICE-ORIENTED INTEGRATION OF THIRD-PARTY PAYMENT GATEWAYS WITH ORACLE EBS IN GOVERNMENT FINANCE SYSTEMS

Abstract

Modernizing financial workflows in U.S. government agencies is critical to improving operational efficiency, ensuring compliance, and delivering citizen-centric services. Oracle E-Business Suite (EBS), widely adopted across public sector organizations, often relies on batch-based, manual payment processes that limit transparency, delay disbursements, and increase reconciliation errors. This paper presents a service-oriented architecture (SOA) framework for integrating third-party payment gateways—such as Pay.gov, Stripe, or regional banking APIs—with Oracle EBS to streamline transaction workflows and enable real-time financial data exchange. The proposed integration leverages secure APIs, middleware orchestration, and role based controls to reduce latency, strengthen auditability, and meet federal compliance standards like FISMA and PCI-DSS. A case study from a U.S. state agency is used to demonstrate tangible improvements, including a 60% reduction in payment reconciliation time and enhanced citizen refund processing. The approach not only supports operational agility and cybersecurity goals but also contributes to broader digital transformation initiatives across the American public sector. By adopting a service-oriented integration model, local and state governments can modernize legacy ERP ecosystems and enable more responsive, accountable financial operations.
