RPA procurement automation system combining UiPath orchestration with AI-powered document intelligence to automate invoice processing end-to-end. PDF invoices flow through OCR and NLP engines for semantic analysis, generating structured JSON data that feeds a UiPath queue for robotic processing. Dispatcher and Performer robots execute UI automation against SAP ERP and Mouser portals, with centralized middleware managing credentials, logs, and transaction monitoring. This architecture demonstrates best practices for scaling RPA with AI: decoupling ingestion from automation, centralizing orchestration, and maintaining audit trails across external systems.
