The Best Business Expense Cards in 2026

How We Evaluated These Cards

Choosing a business expense card is less about the rewards rate on the sticker and more about what you actually qualify for, and what it costs once fees, minimum balances, and repayment terms are factored in. We compared six cards and platforms across four criteria: underwriting requirements (does it need a personal credit check or guarantee), total cost (subscription fees, card fees, and payment fees, not just headline cash back), spend controls and accounting integrations, and who realistically gets approved. Every card below has published, verifiable pricing and eligibility terms as of August 2026.

Ramp

Ramp is a free corporate charge card paired with expense management software, and businesses must pay the full statement balance each period since there is no revolving credit. There is no card fee and no monthly fee, and cash back runs up to 1.5 percent, though Ramp told NerdWallet in 2026 that actual rates now vary by customer between 0 and 1.5 percent rather than a single published rate. To qualify you need at least $25,000 in a US business bank account; there is no personal credit check and no personal guarantee, and sole proprietors are not eligible, while corporations, LLCs, limited partnerships, and nonprofits are. The optional Ramp Plus tier adds AI driven approval workflows and ERP integrations for a per-user fee. The tradeoff is support: NerdWallet found Ramp leans heavily on automated help rather than live agents.

Brex

Brex is a charge card built for funded startups, with credit limits that scale to your cash balance and revenue rather than a founder's personal credit score. Pricing has three published tiers: Essentials is free and includes global card acceptance and basic accounting integrations, Premium is $12 per user per month and adds custom approval chains and multi-entity support, and Enterprise is custom priced. Eligibility is tiered by how much cash and revenue you have: funded startups need roughly $50,000 in cash for monthly payment terms, while unfunded companies generally need more than $500,000 in annual revenue to qualify at all. The biggest 2026 development is ownership: Capital One completed its acquisition of Brex in April 2026 for $5.15 billion, roughly half cash and half stock, a steep discount to Brex's 2022 valuation of $12.3 billion. Brex's own CEO stayed on, and the card continues to operate under the Brex brand.

BILL Spend and Expense (formerly Divvy)

BILL Spend and Expense, the product formerly branded Divvy, is free software bundled with physical and virtual cards, monetized through interchange rather than subscription fees. There is no published minimum revenue or time in business; BILL says approval is based on a multi-input review of cash flow and financial health, and the application involves only a soft credit check on the business and its authorized signer, not a hard pull. Credit lines are advertised from $1,000 up to as much as $15 million depending on approval, with no security deposit or personal guarantee required under BILL's own published terms. The catch is transparency: because BILL does not publish a numeric eligibility threshold, you cannot self-assess before applying, and some independent reviewers report the pre-approval flow now asks for the owner's personal credit score, which complicates BILL's no-personal-guarantee claim in practice.

Mercury IO

Mercury IO is a charge card tied directly to a Mercury business bank account, and your credit limit is a function of your account balance rather than your credit history. Mercury explicitly states it runs no credit check during signup and that using IO has zero impact on personal credit. Rewards are a flat, automatic 1.5 percent cash back with no points program to manage. There is no annual fee, though non-USD purchases carry a foreign transaction fee of up to 3 percent. Keeping at least $15,000 across your Mercury accounts unlocks monthly repayment terms instead of the default daily repayment cycle new customers start on. The requirement to open and fund a Mercury bank account first is the main limitation if you already bank elsewhere.

Expensify Card

The Expensify Card is a debit style card that draws directly from your own business bank account rather than extending credit, which means there is no credit check, no personal guarantee, and no minimum balance requirement at all. Cash back starts at 1 percent and rises to 2 percent once a company's total card spend passes $250,000 in a month, and putting at least half your spend on the card earns 50 percent off the underlying Expensify software subscription. Card issuance is limited to businesses registered in the US, UK, or a handful of EU countries, so it will not work for every international team. It is the simplest card here to get approved for, since there is genuinely no underwriting step to clear.

American Express Blue Business Cash

Unlike the five products above, Blue Business Cash is a conventional revolving credit card, underwritten the traditional way with a personal credit check on the business owner. There is no annual fee, and it earns a flat 2 percent cash back on all purchases up to $50,000 per calendar year, then 1 percent after that, paid automatically as statement credits rather than points you have to redeem. New cardholders get a 0 percent introductory APR on purchases for 12 months, after which the variable rate runs from 18.49 percent to 26.49 percent. Amex welcome offers rotate frequently, so confirm the live offer on americanexpress.com before applying rather than relying on a figure quoted elsewhere.

How to Choose

If you are pre-revenue or newly formed with cash in the bank but no business credit history, Ramp or Mercury IO are the two that will approve you fastest, since both skip the credit check entirely and key off your bank balance instead. If you have raised a funding round and are scaling headcount, Brex's tiered underwriting was built for exactly that stage, though the Capital One acquisition is worth watching for any changes to terms over the next year. If you would rather not tie a card to a specific bank relationship, BILL Spend and Expense keeps the software free and does not require you to move your banking there first. Sole proprietors and freelancers who cannot get approved for any of the charge card products because they lack a qualifying business entity are usually better served by the Expensify Card, or by a traditional card like Blue Business Cash if they have solid personal credit and want simple flat-rate rewards.

Verdict

For most startups with money in the bank and no interest in a credit check, Ramp is the safest default: it is free, the underwriting is transparent, and the software is genuinely useful on its own. Funded companies planning to scale headcount should look at Brex, with the caveat that a first-year Capital One customer might want to watch for policy changes after the acquisition. Anyone who wants to keep banking and card provider separate should give BILL Spend and Expense a serious look before assuming a fintech charge card is the only free option.
