The purchase card is called the purchase card, which means that small batch purchases are paid directly by the company's credit card and then settled to the credit card company every month. This is the simplest explanation. Its advantages are flexibility, no need to place orders, and low order processing cost. You should know that the average processing cost of an order in the United States is about 100 (including all order-related activities, such as placing orders, tracking orders, receiving goods, paying, etc. Of course, different statistics may give different figures). The disadvantage is that it is difficult to track expenses.
