Expense reporting is the process by which employees document and submit their business-related expenses for reimbursement. This typically includes costs such as travel, meals, and supplies incurred while performing job duties. Employees usually fill out a form detailing each expense, attaching receipts as proof. Once submitted, the expense report is reviewed by a manager or finance department to ensure accuracy and compliance with company policies. After approval, the employee is reimbursed for the approved expenses, often through payroll or direct deposit. This process helps organizations track spending and manage budgets effectively.
