Nothing on this list is unusual for a business that has been trading. It matters here because a higher-risk file is read closely: an underwriter is trying to understand a model rather than tick a box, and it is the gaps that create questions.

Every account is subject to underwriting and approval. Documentation requirements differ by business model and by the reviewing bank.
