Complexity grows quietly
One entity is usually readable. Two or three can still feel manageable. Then a new company, payment flow, or reporting currency appears, and the owner no longer knows whether the group view is complete.
Multi-entity reporting works best when the structure is designed before the month-end pressure starts.
Keep two layers
- Entity-level reports for local detail
- Group-level summaries for owner decisions
- Clear eliminations and intercompany notes
- A single language for KPIs across the group
- A short list of exceptions instead of a long list of every transaction
The goal is not to hide detail. The goal is to separate detail from the decisions that need to be made at group level.
A practical rule
If a number appears in the group report, the owner should be able to trace it back to the entity-level source. If that trace takes too long, the reporting model needs simplification.
