TL;DR

The Blue Business Plus is the most useful no-fee business card in the Amex lineup for businesses that periodically need to float a purchase. The 12-month 0% intro APR plus 2x Membership Rewards on the first $50k of spend ($100,000 in points = $600 cash or up to $2,000 transferred) makes it a structurally strong starter business card.

Math worked example, after intro period

$10,000 balance at 22.49% APR (midpoint of 18.49-26.49%):

• $300 per month: 47 months to payoff, $4,026 interest
• $500 per month: 24 months to payoff, $2,485 interest
• $1,000 per month: 11 months to payoff, $1,135 interest
• Minimum payment only (1% plus interest): 19+ years, over $14,800 in interest

Math worked example during intro period

$10,000 in new purchases during the 0% intro APR period:

• $834 per month for 12 months: $10,008 paid, $0 in interest
• $500 per month for 12 months: $6,000 paid, $4,000 remaining balance at month 13
• After intro period, $4,000 remainder at 22.49% APR accrues interest going forward

The 0% intro applies only during the 12-month window from account opening. Any balance carried past month 12 reverts to the variable APR.

2x MR earning math

The 2x rate applies to the first $50,000 of purchases per calendar year. Maximum 2x earning:

• 100,000 Membership Rewards points (at 2x on $50k)
• Worth $600 cash redemption (at 0.6 cents per point)
• Worth up to $2,000 transferred to airline partners (at 2 cents per point)

After $50,000 in annual spend, the rate drops to 1x. For businesses spending more than $50,000 a year, splitting spend with a higher-tier card (Business Gold for 4x in select categories, Business Platinum for 5x on Amex Travel flights) optimizes the rewards yield.

Why this card has a balance transfer caveat

The Blue Business Plus is structurally a revolving credit card and accepts balance transfers in principle, but Amex does not advertise a 0% intro APR balance transfer promo for this card. The 12-month 0% intro applies to purchases only. Balance transfers (if requested) accrue at the standard purchase APR plus the typical 3% transfer fee. For consolidating business debt, look at non-Amex business cards with explicit 0% transfer offers.

Avalanche priority for businesses

The Blue Business Plus APR (18.49-26.49%) is at the lower-to-mid range for business credit cards. If your specific rate is at the low end (18.49%), this card is likely NOT your highest-rate business debt and other cards take avalanche priority. If your rate is at the high end (26.49%), this is likely your highest-rate card and starts the avalanche.

When the Blue Business Plus math works

The card is structurally net positive for businesses:

• Spending $50,000 or less a year (the 2x cap matches the typical small-business profile)
• Wanting flexibility to float occasional large purchases at 0% APR
• Building Membership Rewards points for future travel redemptions
• Operating domestic-only (the 2.7% foreign transaction fee makes the card a poor choice for international spending)

For this profile, the card produces $300-1,200 a year in net rewards value with no annual fee.

When the Blue Business Plus does not work

For businesses spending heavily in 4x or 5x categories on the Business Gold or Business Platinum, the 2x cap leaves real value on the table. The Business Gold’s 4x on top-2-of-6 categories (up to $150k) produces 600,000 points at the cap, versus the Blue Business Plus 100,000 points at its $50k cap. Above $50k in spend, the higher-fee Business Gold typically wins on net even after the $375 fee.

Should you keep Blue Business Plus during payoff?

No annual fee means no carrying cost. Three rules during payoff:

1. Pay extra on the Blue Business Plus only if its APR is your highest among business cards.
2. Stop using the card for new purchases while you carry a balance past the intro period. The grace period is forfeited and new purchases accrue interest from day one at the variable APR.
3. Keep the account open even after the balance is cleared. Closing reduces business credit line and hurts utilization on remaining business cards.

Frequently asked questions

What is the APR on the Amex Blue Business Plus?

The variable Purchase APR is 18.49-26.49% as of May 13, 2026, per American Express pricing. The rate is set at application based on the business credit profile and prime rate at the time, then floats with the prime rate published by the Federal Reserve. New applicants receive a 0% intro APR on purchases for the first 12 months from account opening. The post-intro rate appears on each monthly statement under “Purchase APR.”

Does the Blue Business Plus have an annual fee?

No. The Blue Business Plus is $0 annual fee, which is the structural differentiator versus the Business Gold ($375) and Business Platinum ($695). The trade-off is a lower rewards ceiling (2x capped at $50k of annual spend) versus the higher-tier cards. For businesses with under $50k in annual card spend and no need for the premium credits on the higher-tier cards, the no-fee Blue Business Plus produces the cleanest math.

How does the 12-month 0% intro APR work?

The 0% intro applies to purchases made during the first 12 months from account opening. New applicants pay 0% in interest on any carried purchase balance during this window, as long as the minimum payment is made on time each cycle. After month 12, any remaining purchase balance reverts to the standard variable purchase APR (18.49-26.49%). The 0% promo applies to purchases only; balance transfers accrue at the standard purchase APR plus transfer fee.

Can I do a balance transfer to the Blue Business Plus?

The card accepts balance transfers in principle (it is a revolving credit card with a preset credit limit), but Amex does not advertise a 0% intro APR balance transfer promo for the Blue Business Plus. Balance transfers accrue at the standard purchase APR (18.49-26.49%) plus a typical 3% transfer fee. To consolidate business debt at 0% APR, look at the Chase Ink Business cards or Capital One Spark Cash Plus, which run 0% transfer offers.

What is the minimum payment on the Blue Business Plus?

Per the Cardmember Agreement, the minimum payment is roughly 1% of the new balance plus billed interest and fees, with a $40 floor. Paying only the minimum on a $10,000 balance at 22.49% APR keeps you in debt for over 19 years and costs more than $14,800 in interest. The disclosed time-to-payoff appears on every statement under the CARD Act minimum-payment warning box (TILA Regulation Z).
