Revenue recognition, close management, multi-entity and approval controls, in a system where the subledgers are the ledger rather than modules synced to it.
Revenue, AR, AP and schedules post into the same journal the statements read. There is no integration between them to break.
Executable checks, flux analysis, subledger tie-outs and a period lock that actually locks.
Approval ceilings, segregation of duties and an audit trail that does not need maintaining.
Each of these is a product page describing code that exists.
A seeded company, a close in progress, and every number computed by the engines.
