Light vs OneStream

OneStream is an enterprise corporate performance management platform that unifies financial close and consolidation, planning, reporting and analytics on one data model. It is strong on group consolidation, account reconciliations, driver-based and workforce planning, tax provisioning and ESG reporting, with AI agents built into those workflows. It is not an ERP: it sits alongside the ERPs your entities run and pulls their data in through connectors. Light is the agentic ERP where the ledger and the consolidation are the same system, so the group numbers are the books rather than a platform built above them.
