What implication does using a per diem have on travel expenses for employees?

Using a per diem for travel expenses provides employees with a predetermined daily allowance to cover costs such as meals, lodging, and incidentals while traveling for work. This approach significantly simplifies the reimbursement process because employees do not need to save or submit itemized receipts for every expense they incur. Instead, they receive the set daily amount, which reduces administrative burdens for both the employee and the employer and encourages easier tracking of travel-related costs.

This structure contrasts with reimbursement methods that require detailed records, which can be time-consuming for employees to compile and for organizers to process. By contrast, the other choices do not align with how per diem is typically utilized, such as implying it serves as a fixed salary or suggesting it is relevant only to international travel. Thus, the simplicity and efficiency of using a per diem is what makes this method advantageous for managing travel expenses.
