In the context of corporate travel, an actual expense is the real, documented cost incurred by a traveler during a business trip. This is in contrast to a per diem or estimated amount.
Actual expenses are reimbursed based on receipts and proof of purchase for costs such as airfare, lodging, meals, and ground transportation. This method ensures that the company only covers what was spent, promoting accuracy and accountability in corporate travel budgeting and expense reporting.
