I wonder why companies prefer to use a corporate credit card over debit cards (which are very easy to get)? Do they just like having the line of credit? Is it really worth the extra complication/hassle/thing to worry about just to push off payments by ~15 days (Stripe seems to require that the balance be paid off each month)? I also wonder how that is enforced (by reducing credit limits as a company's bank balance starts to decrease, or by charging interest, or by just eating the defaults)?

Or is it about managing/reporting expenses better across groups an organization? Or do companies just like the rewards?

I understand that interchange fees are higher for credit cards - so are corporate credit cards basically a way to extract additional fees from merchants and distribute them in the form of rewards/cash back to the cardholders?
