Rates and fees verified directly from each company's own site as of October 4, 2026. Subject to change; confirm current terms before applying.

Here's the reasoning and the trade-offs behind each number.

Card-by-card verdicts

Rho

Ideal for: Startups that want their corporate card cashback tied to the rest of their banking relationship, and that are comfortable keeping a meaningful balance at Rho to qualify for the higher rate.

Our take: Rho's standard rate (1.25% on Daily Terms, 1% on Monthly Terms, terms apply) is lower than Mercury's flat 1.5% if you don't qualify for Platinum. Platinum gets you up to 2% on Daily Terms or up to 1.75% on Monthly Terms (terms apply), but it requires routing payroll and revenue through Rho and holding the majority of your company's assets there. That's a real concentration decision, not a free upgrade.

The $1M annual cap on eligible spend and the 12-month redemption window (after which unredeemed cashback is forfeited, terms apply) are both worth knowing before you plan around the rate.

Pros:

• No personal guarantee, no personal credit check

• $0 annual, subscription, or per-card fees

• Physical, virtual, and vendor cards on the Mastercard World Elite Business network

• Cashback rate scales up (not down) the more of your banking you consolidate at Rho

Cons:

• Platinum's top rate requires routing payroll and revenue through Rho and keeping most company assets there

• Monthly Terms requires a $25,000 balance at Rho ($75,000 combined with linked accounts), subject to underwriting

• Cashback is capped at $1M in eligible spend per calendar year and unredeemed cashback expires after 12 months

• Standard (non-Platinum) rate is lower than Mercury's flat 1.5%

Rho is the only one of these six cards that ties its cashback to a broader banking relationship instead of a single-purpose rewards program. Moving your payroll, revenue, and banking to Rho is the tradeoff for a rate and a relationship that scale together, instead of adding a separate rewards card on top of a bank account held elsewhere.

Ramp

Ideal for: Startups that want strong default spend controls and expense automation and are willing to apply without knowing the cashback rate in advance.

Our take: Ramp doesn't publish a cashback percentage or range on its card page or pricing page as of this writing. That's not unusual for Ramp specifically, but it means you can't comparison-shop the rate the way you can with Rho, Mercury, or Airwallex before you apply.

Pros:

• No personal guarantee or personal credit check required

• Strong reputation for built-in spend controls and automation (qualitative, not a figure we can cite)

Cons:

• Cashback rate is not published anywhere on Ramp's own site

• Minimum balance or revenue requirement to qualify is not published

• Annual fee is not stated on the card or pricing pages

Brex

Ideal for: Venture-funded startups or higher-revenue companies that spend heavily in categories Brex rewards at a multiplier, like rideshare, travel, and software.

Our take: Brex's rewards aren't a flat rate. You earn more in a handful of categories (up to 7x on rideshare) and fall back to 1x on everything else, so your effective rate depends heavily on your spend mix.

Pros:

• No personal guarantee required

• Multiplier rewards can beat a flat rate if your spend concentrates in the rewarded categories

• Mastercard network, accepted in 210+ countries

Cons:

• Falls back to 1x on most general spend outside the bonus categories

• Requires a $50,000 minimum cash balance (if funded) or $500,000+ in annual revenue to qualify for daily payment terms

• Annual fee status is not stated on the current card product page

Mercury

Ideal for: Startups that already bank with Mercury and want a simple, flat cashback rate with no tiers to track.

Our take: 1.5% flat, unlimited, and unconditional is the simplest rate of the six: no spend minimums, no merchant restrictions, no promotional end date. It beats Rho's and Brex's standard rates, and once you account for Airwallex's real spend minimums, it's the most straightforward flat rate on this list even though it isn't the highest headline number.

Pros:

• Flat 1.5% cashback on all spending, no categories or tiers

• No annual fee

• No personal guarantee

Cons:

• Starts on daily repayment terms; 30-day terms require a $15,000 balance

• Rate is fixed, so there's no path to a higher tier the way Rho or Brex offer

Airwallex

Ideal for: Startups with meaningful US-merchant spend who want a simple promotional rate and no FX fees, and who can read past the headline number to the terms behind it.

Our take: Airwallex advertises “2% cashback on every purchase, with no cap” on its cards page, but the promotional terms linked from that same page describe a materially different benefit: up to 1.5% on USD transactions of $25 or more at US merchants only, and only if you spend at least $2,000 on the card that month. The promotion is scheduled to run through December 31, 2026, and Airwallex can extend, shorten, or end it early.

The lack of foreign transaction fees is still a genuine advantage for companies paying vendors or contractors abroad, and there's no minimum balance requirement to get the card itself.

Pros:

• Up to 1.5% cashback on qualifying US-merchant transactions (promotional, see terms; scheduled through at least December 31, 2026)

• No monthly fee, no setup fee, no minimum balance requirement to hold the card

• No foreign transaction fees, conversions at the interbank rate

Cons:

• The advertised “2%, no cap” headline doesn't match the linked promotional terms, which cap the real rate at up to 1.5% and require a $2,000 monthly minimum spend

• Company cards are virtual-only; only employee cards come in physical form

• Visa network, not Mastercard, which matters only if your vendors have a network preference

BILL Spend & Expense

Ideal for: Startups that want budgeting and expense-management software bundled with the card itself, rather than a high cashback rate.

Our take: BILL doesn't publish a cashback percentage, just a qualitative “earn rewards” statement, so this isn't the card to pick for the rate. The wide credit-line range ($1,000 to $5M) suggests it serves a broad range of company sizes, but approval and the actual line you get are individual.

Pros:

• No per-user subscription fee

• Wide credit-line range to grow into

• Budgeting tools built into the same product

Cons:

• No published cashback rate or range

• Personal guarantee requirement isn't stated either way on the product page

• Card network isn't disclosed on the product page

How corporate cards work

Corporate charge card vs. business credit card

A corporate charge card is issued based on your company's financials, not your personal credit. You don't sign a personal guarantee, and the issuer doesn't pull your personal credit report. A traditional business credit card from a bank almost always requires both, which is why those cards show up under your personal credit history and a missed payment can follow you personally.

Corporate cards from Ramp, Brex, Mercury, Airwallex, BILL, and Rho are not revolving credit either. The balance is expected to be paid off on a set schedule (daily or monthly, depending on the issuer and your terms), not carried.

Virtual cards are instant; some lock to one vendor

Ramp, Brex, Mercury, Airwallex, BILL, and Rho all issue virtual cards instantly, so you can set up a new recurring payment or a one-off vendor charge without waiting on plastic. Several, including Rho, also support vendor-specific cards, meaning you can issue a card locked to a single vendor or spend category so a subscription or a contractor payment can't be used anywhere else.

Spend limits live at the card level, not in a policy document

Ramp, Brex, Mercury, Airwallex, BILL, and Rho each let an admin set limits by employee, department, or card type, and most let you freeze or cancel a card instantly if an employee leaves or a card number is compromised. This is the main practical advantage corporate cards have over handing out a shared company credit card: the limits live at the card level, not just in a policy document.

Accounting sync is standard; how deep it goes varies by issuer

Corporate cards generally sync transactions to your accounting software automatically, cutting down on the manual receipt-matching that comes with a traditional card program.

How deep that sync goes (categorization, receipt capture, close-the-books automation) varies by vendor, and it's worth testing against your own accounting workflow before you commit.

Methodology

Every Rho cashback, fee, and eligibility figure comes directly from rho.co/product/corporate-cards, read on October 4, 2026.

Here's how that sourcing worked in practice: every competitor figure is sourced directly from that company's own website, its card product page, pricing page, or published support documentation, also read on October 4, 2026, with the specific URL and date cited in our internal fact-check record.

None of the figures for Ramp, Brex, Mercury, Airwallex, or BILL Spend & Expense come from a third-party review site, forum, or comparison article. Where a vendor hasn't published a number, this comparison says “not published” rather than estimating it.

This comparison is published by Rho, a company that issues a corporate card. Every figure above is traceable to a primary source and a date, so you can verify any of it yourself rather than take our word for it.

How to apply

Ramp, Brex, Mercury, Airwallex, BILL, and Rho each have their own application flow on the issuer's own site.

For Rho specifically, you'll need a US-incorporated business with an EIN. Monthly Terms eligibility depends on holding $25,000 at Rho, or $75,000 combined with linked external accounts, subject to underwriting. Businesses that don't meet the Monthly Terms balance apply on Daily Terms instead.

Start an application for Rho's corporate card to move forward, or to talk with a Rho expert about which terms your business qualifies for first.
