A multi-entity close can look complete while one basic fact remains unproven: which legal entity actually owns each bank account. The ledger may show a tidy cash balance for every company, and the consolidation worksheet may balance, but if the account-to-entity link is wrong, the cash, the intercompany balances, and the eliminations are all resting on a nickname in the accounting software.
This protocol asks how an offshore bookkeeping team can test that link from observable records. The unit is one bank account for one legal entity for one reporting period. A single account can produce several units over time if ownership, signatories, or the entity structure changes. The output is a tested link with a source, an effective date, a reviewer, and a stated limitation. It is not a legal opinion and it does not replace the client's consolidation policy.
The scope is the cash side of a multi-entity close: bank accounts, card accounts, and payment-processor accounts that feed the ledger. The protocol does not cover every intercompany transaction, nor does it decide whether an entity should be consolidated. It tests whether the evidence needed to support the cash mapping is present and reviewable before the accounting owner signs the consolidation.
