We refer to this as “deep learning” because the neural networks that enable this kind of learning can be numerous layers deep.

Any out-of-policy or non-business related expenses claimed as a business expense should raise a flag for an expense auditor to review. This can lead to requests for further proof, such as manager approval records or merchant receipts. An expense auditor may deny a fraudulent, unreasonable, or non-compliant claim, leading to denial of the reimbursement.

Finance managers can then record the reimbursed amounts as business expenses, which then affects their net income and tax exemptions.
