How do I increase my Amex Blue Business Cash credit limit?

You can request an Amex Blue Business Cash credit limit increase online, through the American Express mobile app, or by calling customer service at 1-800-492-3344. To raise your chances of being approved for a higher credit limit, pay your bill on time for at least six straight months, reduce your outstanding debt, and update the income American Express has on file. American Express will be more likely to increase your credit limit if the revised income clearly shows that you can afford a higher limit.

4. Enter your total annual income and the amount of the increase you want. Click "Continue."
5. Confirm the information entered and click “Submit Request” to complete the request.

You should receive a decision in just a few seconds. If you’re approved for an Amex Blue Business Cash credit limit increase, the new limit is effective immediately.

Impact of an Amex Blue Business Cash Credit Limit Increase on Your Credit Score

When you request an Amex Blue Business Cash credit limit increase, American Express will conduct a soft pull of your credit report, which does not affect your credit score. However, some Amex Blue Business Cash credit limit increase requests may involve a hard pull, which will cause a short-term dip in your credit score. American Express cannot do a hard pull without your permission.

Alternatively, you could be eligible for an Amex Blue Business Cash credit limit increase without even requesting one. The Amex Blue Business Cash may offer an automatic credit limit increase if American Express’s regular review of your account shows a history of on-time payments and low debt.
