The Expanded Buying Power feature in the Blue Business® Plus card American Express® gives you more room on your spending when business spending gets dynamic. It allows you to spend beyond your original credit limit. This extra credit limit is not unlimited, though. It is given to you based on a host of factors such as your use of the card, your payment history, your credit history and other financial information you have provided upon application.

With the Blue Business® Plus card American Express® you will earn 2X Membership Rewards points on everyday eligible business purchases up to $50,000 per calendar year. Once you have reached the $50,000 threshold, you will start earning 1X Membership Points on eligible business purchases. The points are redeemable for travel, gift cards and statement credits. You can transfer points to a number of partner airlines, most of them at a 1:1 ratio.
