While the terms 'corporate card' and 'business credit card' are often used interchangeably, they can mean radically different things in how they're used and who maintains liability and responsibility for the charges. Most commonly, corporate cards are issued to larger companies with significant revenues. Liability may be negotiated between the business and the issuer. They don't often carry a personal guarantee. Many business credit cards give the business the ability to add authorized users, and issuers have come a long way in recent years in adding new features to monitor spending and manage the authorized cards to allow employees to spend as needed while giving the business owner more oversight.
