American Express OPEN is the division of Amex that deals with small business credit cards, including two of the most recognizable business credit cards available — the Business Gold Rewards Card and the Business Platinum Card. Amex OPEN cards come with a variety of exclusive perks, such as OPEN Savings, which provides additional Membership Reward points and special discounts on eligible purchases. Many Amex OPEN cards are charge cards, not revolving credit cards. This means you’ll need to pay off your balance in full each month, rather than being able to carry a balance from month to month. On the plus side, charge cards don’t charge interest fees because you pay off your balance each billing cycle. Similar to the Ink Business Preferred card from Chase, the Amex OPEN Business Gold Rewards Card offers bonus rewards in business-centered categories, including shipping charges. Unlike the Ink Business card, however, the Business Gold card lets you choose the category for which you want the biggest bonus. The Platinum Card is a good option for frequent travelers, providing a significant Membership Rewards point bonus for travel purchases made through the Amex travel portal. Your Platinum Card also comes with an annual airline credit, airport lounge access, as well as providing bonus rewards for large purchases. The Business Platinum Card is by far one of the most premium business cards you can carry and comes with vast benefits for business persons who spend a lot of time in airports.
