What information is typically required from travelers for reimbursement of expenses?

The requirement for receipts for all claimed expenses is essential for reimbursement processes. Receipts serve as proof of the actual expenditures incurred during travel, providing a clear record that can be audited if necessary. This documentation is crucial for ensuring that the expenses are legitimate and align with the guidelines set by the organization or governing body overseeing the reimbursement. Without receipts, it would be challenging to verify the accuracy of the claims or to justify the expenditure to stakeholders, such as finance departments or auditors.

In contrast, personal preferences regarding travel, detailed breakdowns of meal selections, and lists of approved vendors, while potentially relevant in certain contexts, do not directly validate the reimbursement claims as effectively as receipts do.
