Amex Blue Business Plus Review: Best 2% Flat-Rate Card

Ditch the complex bonus categories and spreadsheets for a single card that treats every dollar the same. If you are tired of wondering if a purchase counts as 'travel' or 'office supplies,' the American Express Blue Business Plus is the simplest way to keep your cash flow moving toward a free vacation. It is built for the business owner who wants high-tier rewards without the high-tier annual fee overhead.

What it actually is

The American Express Blue Business Plus is a credit card for small business owners that offers a flat-rate Membership Rewards point structure. Unlike 'charge cards' that require payment in full, this is a standard credit card with a defined credit limit and an Expanded Buying Power feature that allows for flexible spending.

Fees & Pricing

According to the American Express official fee schedule, the primary appeal is the lack of a yearly overhead cost for the privilege of carrying the card.

Fee Type	Cost	Source
Annual Fee	$0	American Express
Foreign Transaction Fee	2.7%	American Express
Intro APR	0% on purchases for 12 months	American Express
Regular APR	18.49% - 26.49% (Variable)	American Express

Features that matter

• Universal 2x Rewards: Earn 2 Membership Rewards points per dollar on the first $50,000 in purchases each year. After that, it drops to 1x. This is perfect for paying your Google Business Profile ads or SBA loan-funded inventory.
• Expanded Buying Power: Amex allows you to spend beyond your credit limit. While not a 'no-limit' card, it adjusts based on your payment history and financial profile.
• Zero-Percent Runway: The 12-month 0% intro APR on purchases acts like a low-interest bridge loan for new equipment or stocking up before a busy season.
• Transfer Partners: Unlike cash-back cards, these points can be moved to airlines like Delta or hotel chains, often yielding more than 1 cent per point in value.

Where it falls short

• The $50k Ceiling: If your business spends $20,000 a month on inventory, you will hit the 2x rewards cap by early March. After that, you are earning a meager 1%, which is subpar.
• International Friction: Taking this card on an international trade show trip is a mistake. The 2.7% foreign transaction fee effectively wipes out the value of the 2x points you’re earning.
• Customer Support Gaps: While Amex ranks high in J.D. Power studies, verified Trustpilot reviews (averaging 1.6/5 stars as of late 2023) frequently cite long hold times and automated responses for disputed business charges.

Phase 1: Before You Apply

• Check your credit score; typically requires 670+ for approval.
• Review last year's spending to see if you exceed $50k.
• Confirm you have no international vendor payments planned.
• Compare against the 'Blue Business Cash' if you prefer dollars.

Phase 2: Setting Up for Success

• Create an Amex online account to monitor Expanded Buying Power.
• Download the Amex Business App for real-time purchase alerts.
• Connect your card to QuickBooks or Xero for auto-reconciliation.
• Order free employee cards to centralize all team spending.

Phase 3: Maximizing the Points

• Use the card for the first $50,000 of general spend.
• Switch to a secondary card once you hit the cap.
• Check 'Amex Offers' monthly for specific vendor statement credits.
• Link your Membership Rewards to a high-value airline partner.

Who it's best for

This is the ultimate tool for a solo consultant or a 3-person service business (like a local HVAC or landscaping crew) that spends between $2,000 and $4,000 a month. It provides a simple, high-yield way to turn everyday bills into travel rewards without a $500 annual fee hanging over your head.

Alternatives to consider

• Chase Ink Business Cash: Better if you spend heavily on internet, cable, and phone services (5% back).
• Capital One Spark Miles: A better choice if you spend way over $50k/year and want unlimited 2x miles.
• Amex Business Platinum: For the high-roller who needs premium airport lounges and has a massive travel budget.
