ChatFin is like hiring a tireless accounting assistant that lives inside your existing finance software and quietly handles the repetitive parts of closing the books, paying bills, and chasing invoices. ChatFin deploys agentic AI across the finance spend lifecycle — pre-authorization, receipt capture, coding, approval, ERP posting, spend analytics, and vendor benchmarking — connecting natively, without CSV exports, to 16+ ERP systems including NetSuite, SAP, Oracle EBS and Workday. It includes human-in-the-loop approval workflows and a full audit trail, and claims to shrink month-end close from 10 days to 3.
