How do the main US corporate cards compare?

“Corporate card” can mean either a credit/charge card or a company-funded card—and those aren’t interchangeable. Here’s a practical comparison of the main options for U.S. businesses:

Quick take: For expense controls and automation, compare Ramp, Brex, and BILL Divvy. For points and travel benefits, look at Brex or Amex Corporate. For international spending from held balances, consider Airwallex—but treat it as a different product category from a credit card.

Before choosing, check three things: how the card is funded and repaid, what the rewards are actually worth to your business, and whether the software costs extra. Approval requirements, credit limits, and terms vary, so the best fit depends on your company’s finances and spending pattern.

The main options split into fintech spend-management cards (Ramp, Brex, BILL Divvy) and traditional Amex or bank cards. The fintech cards generally have no fees and no personal guarantee but require cash on hand. Amex cards carry annual fees and richer perks.

Ramp

• It has no annual fee on its base tier. It has a $0 annual fee and a $0 foreign transaction fee.
• Eligibility is based on the business. The Ramp Corporate Card only requires your corporation to have $25,000 in any U.S. business bank account to qualify, and there's no personal credit check or personal guarantee.
• Rewards are the weak point. One August 2026 report says Ramp's cashback is now a variable 0–1.5% set per business rather than a flat published rate, and Ramp added a $0.59 fee on standard ACH payments. Older comparisons still cite a flat 1.5%, so check your own rate.
• Its paid tier, Plus, is $15/user/month, plus a platform fee based on team size.

Brex

• Brex is the usual pick for venture-backed startups. Its base tier has no fee, and Premium is $12/user/month.
• Rewards are points by category. The sources differ on the top multiplier, with 7x on rideshare, 4x on travel, 3x on restaurants, 2x on software subscriptions, 1x on everything else.
• Qualifying is harder. One comparison says Brex requires a minimum $50K in cash reserves to qualify. Another notes Brex wants startups to have equity investments or at least $50,000.

American Express corporate and business cards

• These carry real fees. The Business Platinum Card carries an $895 annual fee and earns Membership Rewards points with multipliers on flights booked directly with airlines and prepaid hotels booked through Amex Travel.
• Amex is the most likely of the group to require a personal guarantee. Amex typically requires a personal guarantee and strong credit.
• Its strength is perks and travel value, not lower cost. Amex offers the option to either let your employees keep and use their own points or to send all points to a single bucket owned and operated by the company.

BILL Divvy

• It is a lower-cost alternative. One guide says it suits budget-focused teams with lower cash requirements.

Capital One Spark Cash Plus (charge card)

• It is a higher-fee, higher-reward option. A March 2026 NerdWallet listing shows an annual fee $150 and rewards rate 2%-5% cashback, with the caveat that it requires excellent credit.

Rough guide to choosing

• Pre-revenue or small teams that want simplicity and no personal guarantee: Ramp.
• Funded startups with heavy travel and software spend: Brex.
• Established companies that want premium travel perks and accept fees and a personal guarantee: Amex.
• Companies that need cheaper spend controls with lower cash requirements: BILL Divvy.

Most of these comparisons come from fintech vendors or affiliate-driven sites, and the terms (rates, minimum balances, fees) have been changing in 2026. Confirm current terms directly with each issuer before choosing.

The U.S. corporate card market has evolved significantly, shifting from traditional credit-based products to comprehensive "spend management" platforms. When comparing them, the decision often comes down to your company's size, funding stage, and whether you prioritize deep expense automation or global financial features.

Market Overview: The Main Players

The landscape is generally split between modern fintech platforms (built for automation and control) and traditional issuers (known for travel perks and established credit infrastructure).

• Modern Spend Management Platforms: Companies like Ramp, Brex, Rho, and Airwallex have become the standard for high-growth companies and SMBs. They offer integrated software to automate receipt collection, accounting syncs, and granular spend controls.
• Traditional Issuers: American Express remains the benchmark for executive travel benefits, robust global acceptance, and traditional corporate credit programs.

Key Comparison Factors

1. Ramp vs. Brex: The High-Growth Leaders

Both platforms offer unlimited virtual cards, real-time spend visibility, and automated receipt matching, but they serve slightly different profiles.

• Ramp: Generally favored by businesses focused on cost control and operational efficiency. It is highly regarded for its automation tools, ease of use for accounting teams, and "spend-less" philosophy.
• Brex: Positioned as a global financial platform for venture-backed startups and businesses with international operations. It offers deep travel booking integrations and has significant capabilities for businesses scaling across borders.
  • Note: As of 2026, Brex is operating under new ownership following its acquisition by Capital One; users should verify current platform directions and support.

2. Integrated Platforms (Rho, Airwallex)

Some providers go beyond just cards by bundling banking, bill pay, and treasury services into one dashboard.

• Rho: Focuses on unifying your entire "finance stack"—banking, cards, and accounts payable—into one place to reduce the need for multiple tool integrations.
• Airwallex: A strong contender for businesses with significant international needs, offering multi-currency cards and global expense management that minimizes foreign transaction markups.

Corporate vs. Business Credit Cards

It is important to ensure you are choosing the right category for your company's stage.

How to Choose

1. Define your goal: Are you looking to earn maximum travel rewards (Amex) or reduce manual bookkeeping time (Ramp/Rho)?
2. Evaluate your structure: If you are a venture-backed startup with global employees, a platform like Brex may fit better. If you are a domestic SMB focused on cutting costs, Ramp is frequently cited as a top choice.
3. Check integrations: Before committing, ensure the card program integrates directly with your existing ERP or accounting software (e.g., NetSuite, QuickBooks) to avoid manual data entry.

For U.S. companies comparing corporate cards, the main differences are less about the plastic and more about how the credit line works, rewards, and the expense-management platform. Based on the available current product information:

Quick take: Ramp stands out for a free core spend-management setup; Brex for category-based rewards and international reach; and BILL Divvy for budget-linked cards and rewards that can improve with frequent repayment. ¹⁵⁶¹²

Before choosing, compare the actual approved limit, repayment cadence, reward redemption value, foreign-transaction costs, and which controls or integrations are included in the free tier. Rewards multipliers are not directly comparable—points, cashback, and redemption options can have different real-world values. Eligibility and terms vary, so verify current cardholder agreements and pricing with each provider.
