What can it do for your business?

The uses are as varied as the companies who take advantage of them.

Like any business relationship where trust builds over time, business owners who have consistently paid at least their minimum due on time may have higher spending capacity over their credit limits.

For instance, a company with a $20,000 credit line could make a $35,000 technology upgrade on their Blue Business Cash™ Card, earning $700 cash back to reinvest in their business. 

Already have Expanded Buying Power?

Blue Business Cash™, Blue Business® Plus, and SimplyCash® Plus are eligible Cards.

Expanded Buying Power varies based on factors such as your payment history and credit records. It’s not unlimited and it does change. To double-check if a purchase above your limit will be approved, use the “Check Spending Power” tool within your American Express online account, the American Express® App4, or the American Express® Business App5.
