A member sells a full business-management suite with a native general ledger plus at least one operational domain (inventory and order management, manufacturing or MRP, distribution, projects, field service, retail or hospitality operations) under one data model, delivered as multi-tenant cloud and built cloud-native or re-platformed since about 2008; the incumbent suites (NetSuite, Oracle Fusion, SAP, Dynamics 365, Infor, Epicor, IFS, Workday, Sage Intacct, Intuit Enterprise Suite) are excluded by rule, and accounting-only platforms, AI-native ledgers, operations platforms that keep the customer's ledger, and small-business accounting tools with a stock module are adjacent.
