Your fintech holding company owns two operating entities: NG Ltd in Nigeria and KE Ltd in Kenya. Each has its own books, its own currency (NGN and KES, for this lesson both in NGN for simplicity), its own bank account, its own revenue. Some transactions flow BETWEEN entities, NG pays KE for shared engineering services. From the holding company's perspective (the consolidated group), inter-company revenue and expense must CANCEL, otherwise you'd be double-counting the same money. This lesson posts the per-entity entries, then the elimination entry that produces the consolidated view investors and auditors actually see.
