The American Express Blue Business Plus Card is a no-annual-fee business credit card that earns 2x Membership Rewards points on eligible purchases up to $50,000 per year, then 1x after that ceiling.
It is structurally identical to the Blue Business Cash Card in its fee and spending structure, with one key distinction: it earns transferable Membership Rewards points instead of fixed-value cash back.
What the product is structurally
The Blue Business Plus Card is an American Express credit card on a revolving line. Points accumulate in the cardholder’s Membership Rewards account, connecting to American Express’s transfer partner network of airlines and hotels.
Like the Blue Business Cash Card, it includes the Expanded Buying Power feature, which allows certain purchases above the stated credit limit. The amount of available Expanded Buying Power fluctuates based on payment history and Amex’s credit assessment.
Employee cards are free and contribute earned points to the primary account’s Membership Rewards balance.
How it works in practice
All eligible purchases earn 2x Membership Rewards points through $50,000 in spending each calendar year. Above that threshold, the rate falls to 1x. The cap resets at the start of each calendar year.
Points earned on the Blue Business Plus Card belong to the same Membership Rewards pool as points earned on other Amex cards like the Amex Gold or Amex Platinum. This allows businesses to consolidate points from multiple cards into a single pool before transferring to a partner.
Transfer partners include Delta SkyMiles, British Airways Avios, Air Canada Aeroplan, Hilton Honors, Marriott Bonvoy, and others, typically at a 1:1 ratio. The value of each transferred point depends on the redemption chosen within that program.
Points can also be redeemed for travel through amextravel.com, as statement credits, or for gift cards, though these redemption channels typically deliver lower per-point value than airline or hotel transfers.
Fees and pricing mechanics
There is no annual fee. American Express does not charge foreign transaction fees on the Blue Business Plus Card.
The welcome offer, as of early 2026, provides a defined points bonus after meeting a spending threshold within the first months of account opening. Exact terms are disclosed during application and subject to change.
The variable APR applies to balances not paid in full. Points accumulate regardless of balance status, but interest charges on carried balances reduce the effective value of those earned points in dollar terms.
Limits, eligibility, and availability
The $50,000 annual spending cap affects the card’s value proposition for higher-volume businesses. A business spending $100,000 per year would earn 2x points on the first $50,000 and 1x on the second $50,000, for a blended effective rate below 2x annually.
Eligibility requirements are the same as the Blue Business Cash Card: a U.S. business and a creditworthy applicant with a Social Security number or ITIN. The product covers sole proprietors through larger corporate entities.
The card is not available to non-U.S. residents or businesses incorporated outside the United States.
Tradeoffs, risks, or limitations
The core tradeoff is rewards flexibility versus simplicity. The Blue Business Cash Card delivers a fixed dollar value per dollar spent. The Blue Business Plus Card delivers a variable value depending on how the earned points are redeemed.
If points are redeemed for statement credits or at base travel rates, the effective per-point value may fall below 1 cent — meaning the 2x rate delivers less than 2% in cash equivalent. High-value airline award redemptions can exceed 2 cents per point, making the Blue Business Plus Card potentially more valuable than its cash counterpart — but only with active management of the redemption strategy.
The $50,000 annual cap creates a structural ceiling on how much high-rate earning is possible. Businesses with flat spending above this level may find cards without caps more efficient.
American Express acceptance is not universal. Some merchants, particularly smaller or international ones, accept only Visa or Mastercard. This can limit the card’s practical earn rate in certain spending contexts.
