Amex is revolvoing credit which requires that is paid off at the end of the term.
Revolving credit implies that the balance can be "revolved" or carried from one billing cycle to another. American Express charge or T&E cards require payment in full at the end of the billing cycle, while the AMEX credit cards can be revolved.
Not always. I had a normal everyday Amex that would allow normal “pay over time” expenses if the purchase was large enough. I had to put $3,200 of vehicle repairs on it when my wife got stranded in Atlanta a couple years ago. The interest rate was not good (about 19%), and, well, let’s just say that here I am two years later dealing with the collections agency because Amex was the one card I had that wouldn’t play nice with the credit counseling people. Fortunately their balance will be gone in five more painful months, and I can start to throw that money at the rest of my cards and make some good progress.
