My advice would be to make sure you have more than 1 card. There will be a fraudulent purchase at some point leading to a card re-issue. You don't want to be dead in the water for a few days while that happens!
Thats why i like Amex, their fraud detections systems quite advanced. Even when my card had fraud on it and they issued a new card #. All vendors still worked with the old card number.
Not only that. If you have fraud alert, they'll ship you a new card overnight. From a customer perspective Amex is amazing.
That was the case with my discover too
Very true, learned-from-experience type advice. Some banks my not really get the need and ask a bunch of questions, but in my experience they were more excited for the opportunity to charge more credit card fees :)
I would suggest to get the second business card (not for every employee, but for paying your critical service bills) from a different provider altogether, since the goal is to make sure the backup works when the primary one doesn't for whatever reason. So choose for example your bank's card as primary, with a corporate Amex as backup.
Or just get a credit card through your local bank (or anything with a nearby physical branch). I've had corporate cards replaced and reprinted for me same-day.
