The American Express Blue Business Cash Card is a no-annual-fee business credit card that earns 2% cash back on eligible purchases up to $50,000 per calendar year. After reaching that threshold, the earn rate drops to 1%.
American Express issues the card with the Expanded Buying Power feature, which allows spending beyond the credit limit in certain circumstances. Cash back applies to eligible purchases regardless of whether the balance is paid in full each month.
What the product is structurally
Structurally, the Blue Business Cash Card is an American Express business credit card on a revolving credit line. The product earns cash back in the form of a statement credit — it does not accumulate Membership Rewards points. This distinguishes it from the Blue Business Plus Card, which earns points instead of cash.
The Expanded Buying Power feature allows cardholders to make purchases above the credit limit up to an Amex-calculated maximum. This maximum changes based on payment history, credit profile, and account usage. Charges above the limit must be paid in full by the next statement due date.
Employee cards are available at no cost and pool rewards into the primary account.
How it works in practice
The 2% cash back applies uniformly to all eligible purchases through $50,000 in spending per calendar year — the cap resets on January 1. Above $50,000, all purchases earn 1%. There are no category exclusions or rotating bonus structures within this range.
Cash back appears as a statement credit, applied on the billing statement after it is earned. It does not require manual redemption and does not expire while the account is open and in good standing.
The introductory offer, as of early 2026, provides a statement credit for spending a defined amount in multiple tiers within the first months of account opening. The specific structure changes periodically; current terms are disclosed during the application process.
Fees and pricing mechanics
There is no annual fee. American Express does not charge foreign transaction fees on purchases made outside the United States.
Cash back accumulates at the published rate and converts to statement credit automatically. There are no points or miles currencies to manage, and no partner transfer options — the value is fixed in dollar terms.
The variable APR applies to balances carried beyond the payment due date. Expanded Buying Power charges must be paid in full by the due date or they accrue interest at the applicable rate.
Limits, eligibility, and availability
The $50,000 annual spending cap is meaningful for higher-volume businesses. A company spending $80,000 per year in eligible purchases would earn 2% on the first $50,000 and 1% on the remaining $30,000, for an effective blended rate below 2%.
Eligibility requires a U.S. business and applicant. American Express evaluates both the business and the personal credit of the applicant. A Social Security number or ITIN is required.
The card is available to sole proprietors, LLCs, partnerships, and corporations. It is not available to non-U.S. businesses.
Tradeoffs, risks, or limitations
The $50,000 annual cap is the primary structural limitation. Businesses with spend above this threshold see the effective rate fall below 2% on an annual basis. For high-volume businesses, cards without a cap — such as the Wells Fargo Signify or Capital One Spark Cash — may provide more consistent returns.
The product earns cash back directly rather than Membership Rewards points. Businesses that value transferable points for airline award redemptions would need to evaluate the Blue Business Plus Card, which has the same structure but earns 2x points instead of 2% cash.
The Expanded Buying Power feature introduces a variable limit above the stated credit ceiling. The amount available under this feature is not guaranteed and can change without notice based on Amex’s internal assessments.
