An expense report is a document used by employees to itemize and request reimbursement for expenses incurred while performing their job duties. This can include costs for travel, meals, lodging, and other business-related expenses. The report typically includes receipts and a detailed explanation of each expense to ensure transparency and accountability. Companies often have specific guidelines for submitting expense reports, including deadlines and allowable expenses. Once submitted, the report is reviewed by a manager or finance department, which verifies the expenses before processing the reimbursement. Properly maintained expense reports help organizations manage their budgets effectively.
