What term is used to describe a dollar amount charged to cover hotel, meals, and transportation costs for a designer's travel out of town for a project?

The term "Per Diem" refers specifically to a daily allowance provided to cover travel-related costs such as meals, lodging, and transportation when a designer or any professional is traveling for work. This amount is usually predetermined and allocated on a daily basis, making it easier for both the designer and the client to manage travel expenses.

The per diem allows designers to maintain financial control while away from their home office, enabling them to focus on the project without worrying about receipt collection for every meal or travel-related incident. This simplifies accounting processes for firms and provides clarity for budget expectations.

In contrast, a retainer represents a fee paid up front to secure the designer's services. An invoice is a document requesting payment for services rendered or goods provided. Expense reimbursement refers to reimbursement for specific out-of-pocket costs incurred, rather than a predetermined daily allowance. Thus, per diem is the most accurate term for a specific daily allowance related to travel costs.
