What is the primary function of an expense report?

The primary function of an expense report is to document and justify business expenses. This report allows employees to provide detailed information about expenditures incurred while performing their job duties, ensuring that all expenses are accounted for and can be reimbursed if applicable. An expense report typically includes receipts, descriptions of the expenses, and the purpose of each cost, which is necessary for transparency and financial accountability within an organization.

Choosing this option highlights the importance of maintaining accurate financial records and adhering to company policies regarding reimbursements. The other options focus on aspects unrelated to the financial management of business expenses, such as employee performance evaluation, market analysis, or tracking hours worked, which are distinct functions not covered by an expense report.
