Key factsFree corporate cards compared: Ramp, Brex, Mercury, and BILL

- Brex's Essentials tier is $0 and Premium costs $12 per user per month, rated 4.7 across 1,647 reviews.
- Mercury offers free Business Banking and Treasury, rated 4.6 across 143 reviews, and replaces a company's bank.

Corporate cards are free, and unlike most free software, the reason is simple enough to state in one sentence: the card issuer earns interchange every time you spend, so the spend management software is a customer acquisition cost.
Everything else in this article follows from that. It explains why the free tiers are unusually complete rather than crippled, why the vendors care so much about your card becoming the default, and where the arrangement stops working in your favour.
This compares business products. It is not financial advice, and the decision to take on any credit facility is one to discuss with your accountant.
The ratings
Aggregated by Toolradar across G2, Capterra, TrustRadius and PeerSpot. 4,072 reviews across three products.
| Product | Aggregated rating | Reviews |
|---|---|---|
| Ramp | 4.7 | 2,282 |
| Brex | 4.7 | 1,647 |
| Mercury | 4.6 | 143 |
BILL Spend & Expense, formerly Divvy, is not in the directory and carries no aggregated rating here.
Ramp and Brex are tied at 4.7 on samples of 2,282 and 1,647, which is about as close as two competitors get. Mercury's 4.6 across 143 is encouraging on a much thinner sample, and Mercury is a different kind of product anyway, as below.
There is no bad option in this table, which is genuinely unusual and worth saying rather than manufacturing a ranking.

What "free" is paying for
Interchange is roughly one to three percent of every card transaction, paid by the merchant's bank and split among the parties in the payment chain. A company putting $200,000 a month through a card generates meaningful revenue for whoever issued it.
That has four consequences you should be able to predict.
The free tier is complete, not crippled. Ramp and Brex both give away the whole core product, because a limited version would slow down the thing they actually want, which is card adoption.
Everything is designed to make the card the default. Virtual cards for every subscription, one-click issuing, automated receipt capture. All good features, all pointing the same direction.
Features that do not drive spend sit behind the paid tier. Procurement workflows, complex approval chains and deeper integrations are what Ramp's $15 and Brex's $12 buy, and none of them make you spend more on the card.
Low spend is a weak fit. None of these publishes a minimum, and none of them is a charity. A five-person company with modest card volume is not the customer this economic model was built for, and should read the terms rather than assume free is unconditional.
Ramp
Ramp is the strongest all-round free product in this category and the one to try first for a US-based company.
The free tier includes the cards, the expense management, the receipt matching and the spend analytics. The feature people actually talk about is the one that finds money rather than saving time: it flags duplicate SaaS subscriptions across the company and alerts you when a recurring vendor raises its price.
Plus is $15 per user per month, checked 15 August 2026, and adds procurement and deeper controls.
4.7 across 2,282 reviews, the largest sample here.
Brex
Brex covers the same ground with international as the differentiator: multi-currency spend, entities in several jurisdictions, and local reimbursements across a long list of countries.
Essentials is $0, Premium is $12 per user per month, checked 24 August 2026, undercutting Ramp's paid tier by $3.
4.7 across 1,647 reviews. If your team is in one country, this and Ramp are close enough that either choice is defensible. If your team is not, Brex is the answer and the ratings are irrelevant to why.
Mercury
Mercury is not primarily a corporate card. It is business banking, and the card comes with the account.
That distinction is the whole point. Ramp and Brex sit on top of your existing banking; Mercury replaces it. For a startup that has not yet chosen a bank, getting the account, the card and the spend controls in one place removes a whole integration.
Business Banking is $0 and Treasury is $0, checked 25 August 2026. The $240 figure in its pricing record is the personal product and not what a company would buy.
4.6 across 143 reviews, a good score on a small sample.
BILL Spend & Expense
Formerly Divvy, this is the budget-first option: you allocate a budget to a team, issue virtual cards against it, and the card simply declines past the limit.
That is a meaningfully different control philosophy. Ramp and Brex are excellent at telling you what was spent and flagging what should not have been. BILL prevents it at the point of sale, which removes the conversation entirely.

Where this arrangement stops being good for you
Free corporate cards are a genuinely good deal, and there are three places where the incentives diverge from yours.
Credit limits are set by the issuer, using your cash balance and revenue. They can move. A card programme that comfortably covers your spending can tighten at the exact moment your business changes, which is the moment you would least like it to.
Consolidating spend concentrates a dependency. Every subscription on one card, all controls in one vendor's dashboard, means a service outage or an account issue touches everything at once. Keeping one backup payment method outside the programme costs nothing and is worth doing.
Rewards are a discount on spending, not a saving. These programmes advertise cashback on categories they would like you to use, and a percentage back on money you should not have spent is still money you should not have spent. Ramp's own duplicate-subscription detection is worth more than any rewards rate in the category, and it points the other way.
Choosing
US company, straightforward spend: Ramp, free.
International team or multiple entities: Brex, free.
Pre-bank startup: Mercury, and get the account and card together.
Budget enforcement before the money leaves: BILL Spend & Expense.
The scores will not decide this for you and should not. Two of these products are tied at 4.7 on thousands of reviews, which tells you the category works. What decides it is where your team is, whether you have a bank, and whether you want to catch overspending or prevent it.
Charge card or credit card, and why it matters
The products in this article are not all the same financial instrument, and the difference decides whether you can use them at all.
Ramp and Brex issue charge cards. The balance is paid in full from your bank account on a cycle, typically daily or monthly. There is no revolving credit, no interest, and no minimum payment. The limit is set against your cash and revenue rather than a credit score, which is why a two-year-old company with money in the bank can get a large limit where a traditional bank would have declined it.
The consequence is that these cards do not finance anything. They are a spending and control system, not a source of working capital. A company relying on thirty days of float between paying a supplier and being paid by a customer will not get it here.
Mercury's card sits on your own deposits, which is the same non-credit shape by a different route.
That is worth understanding before the free tier tempts you into consolidating everything. The traditional corporate card you are replacing may have been doing two jobs, and only one of them is being replaced.
What to check before you switch everything over
Three practical items, all of which cost an hour now and a great deal later.
Where the accounting integration ends. Every product here syncs to the common accounting platforms, and the sync covers transactions rather than judgment. Someone still codes the ambiguous ones. Ask to see the integration on your chart of accounts, not on a demo one.
How virtual cards behave at renewal. Locking a subscription to a single-vendor virtual card is the best feature in this category and the one that causes the most incidents, because a card that declines an unexpected price rise also declines a service you needed. Decide deliberately which subscriptions get hard limits.
Who can issue a card. The default in most of these products is more permissive than finance teams expect. Set that policy in week one, while there are five cards, rather than in month nine when there are ninety.
