One chart, one code structure
A shared chart makes consolidation straightforward because account codes line up across entities. Intercompany pairing becomes mechanical rather than interpretive — a due-to account in one entity is matched by code, not by judgement.
The cost is that entity-specific reporting gets slightly blunter, because every entity carries accounts it doesn't use. For a group running similar operations across two or three entities, that bluntness is a fine trade.
Suited to: groups of 2–4 entities with related operations and a small finance team.
