Amex Blue Business Plus Review: No Annual Fee, 2× Membership Rewards on $50K, and a 0% Intro APR
TravelThe Amex Blue Business Plus card earns 2× Membership Rewards points on every business purchase up to $50,000 per calendar year, with no annual fee. Above $50K, the earn rate drops to 1× — so for businesses spending more than that annually, there’s a ceiling on the card’s efficiency.
For businesses under that spend threshold — and for any business that wants transferable points rather than cash back from a no-fee card — the Blue Business Plus occupies a specific and useful position in the Amex lineup.
The Core Value Proposition
Welcome offer: 15,000 Membership Rewards after $3,000 in three months. At a standard ~1.7 cents per point valuation, that’s $255 in travel value — modest but reasonable for a no-fee card.
Earn rate: 2× MR on everything, first $50K/year. The simplicity is the point: no rotating categories, no tracking spend across bonus tiers, no merchant-category exclusions. Everything earns 2× until the cap.
0% intro APR: 12 months on purchases. For businesses with large purchases planned in the next year — equipment, inventory, software contracts — this is meaningful financing flexibility without interest.
No annual fee: The lifetime cost of holding this card is zero (beyond any interest charged if you carry a balance after the intro period).
The Membership Rewards Ecosystem
The Blue Business Plus earns transferable MR points — the same currency as the Amex Business Platinum and Gold. This matters for two reasons:
First, points transfer to ~20 airline and hotel partners, including Delta SkyMiles, British Airways Avios, Air Canada Aeroplan, ANA, Singapore KrisFlyer, and Marriott Bonvoy, among others. At 1:1 transfer ratios and airline sweet spots, points can be worth significantly more than 1.7 cents in premium cabin bookings.
Second, the card functions as a “hub” for Membership Rewards. If you hold a premium Amex card (Platinum, Gold) and are considering canceling it, downgrading or keeping the Blue Business Plus preserves your MR balance without requiring the premium card’s annual fee. Without a card in the account, MR points expire.
The “Plus” vs “Cash” Decision
Amex also offers the Blue Business Cash card with identical structure — no fee, 2% cash back on the first $50K — for people who prefer cash over transferable points. The Blue Business Plus is the better option for anyone who values transfer flexibility and occasionally books premium travel. The Blue Business Cash is the simpler option for people who redeem points as statement credits and don’t want to manage a transfer ecosystem.
The So What
The Amex Blue Business Plus is the cleanest “set it and forget it” business card for moderate-volume Membership Rewards earners. No annual fee eliminates the mental overhead of calculating whether the card pays for itself each year. 2× on everything under $50K means no category management. The 12-month 0% APR makes it especially useful at card opening for businesses with large planned purchases.
The ceiling is $50K — above that, a Platinum or Gold with higher category earn rates becomes the more efficient card. Below that, it’s hard to argue with transferable points at no annual fee.
