A corporate card is usually a credit card held by a corporate company. These cards can have certain executives or employees as authorized users. Then they can be used when travel like flights or hotels need to be booked for corporate travel. Or when food has to be purchased for a business event. This is a good way for companies to keep track of the money they’re spending. It can also be useful come tax season because those expenses can be tax write-offs that are easier to file if they’re organized on one credit card solely used for corporate charges.
