What Mercury Credit Card Offers
Mercury is a business credit card issued by WebBank, designed for small business owners and freelancers who want cash back on everyday spending. The card offers 1.5% cash back on all purchases with no category restrictions, no annual fee, and no foreign transaction fees. There is no sign-up bonus, and the card reports to business credit bureaus rather than personal credit bureaus.
The card is marketed as a simpler alternative to category-based business cards — you do not have to track which purchases fall into bonus categories or worry about rotating categories. Every dollar spent earns the same rate. Mercury also bundles the card with a business checking account and accounting software integration, though you can hold the card without using those products.
Key Takeaways
- Mercury earns 1.5% cash back on all purchases with no bonus categories, annual fee, or foreign transaction fees.
- The card builds business credit history separately from your personal credit, which can help you access business loans later.
- Cash back is deposited monthly into your Mercury business checking account, and you cannot transfer it elsewhere.
- Mercury requires a business checking account to hold the card, which has a $0 monthly fee but requires a minimum deposit to open.
- The card is best for business owners who spend under $50,000 per year and prefer simplicity over category bonuses.
How the Cash Back Works
Mercury pays 1.5% cash back on every purchase, with no caps or limits. The cash back posts monthly to your Mercury business checking account automatically — you cannot redirect it to another bank or take it as a statement credit. If you close your Mercury checking account, you lose access to the card.
The 1.5% rate is lower than what category-focused cards offer in their bonus categories. For example, a card that pays 3% on office supplies and internet will beat Mercury if those categories make up a large share of your spending. Mercury wins when your spending is scattered across many categories and you value simplicity over optimization.
Business Credit Reporting and Building History
Mercury reports card activity to Dun & Bradstreet, Equifax Business, and Experian Business — the three business credit bureaus. This means the card builds your business credit profile separately from your personal credit score. A stronger business credit history can lower interest rates on future business loans and lines of credit.
The card does not report to personal credit bureaus, so it will not help or hurt your personal credit score. This is useful if you want to keep business and personal finances separate, but it also means the card offers no personal credit-building benefit if you are a sole proprietor.
Fees and Costs
Mercury charges no annual fee and no foreign transaction fees. There are no fees for late payments, over-limit transactions, or balance transfers — because the card does not support balance transfers. You pay interest only if you carry a balance month to month.
The Mercury business checking account itself has no monthly fee, but you must maintain a minimum deposit to open it. That minimum varies and changes over time; check Mercury's current terms before opening. If you close the checking account, your credit card is also closed, so you cannot separate the two products.
Approval Requirements and Credit Limits
Mercury reviews both your personal credit and your business financials during underwriting. The card typically requires a personal credit score of 650 or higher, though Mercury does not publish a hard minimum. You will need to provide business tax returns, bank statements, or other proof of business income.
Credit limits start low — often $1,000 to $5,000 — and increase based on your payment history and business revenue. There is no way to request a higher limit upfront. If you need a higher limit when ready, Mercury may not be the right fit.
When Mercury Makes Sense for Your Business
Mercury works best for businesses with straightforward, scattered spending across many categories. If your business spends heavily in one or two categories — such as advertising or software subscriptions — a card with higher bonus rates in those categories will earn more cash back.
Mercury also suits business owners who want to build business credit without mixing personal and business finances. The separate business credit reporting and required checking account create a clear boundary between the two. However, if you already have a business bank account elsewhere and do not want to switch, the Mercury card may feel like an unnecessary tie-in.
The card is less useful for high-spending businesses. At 1.5% cash back, a business that spends $100,000 per year earns $1,500 in cash back. A category-focused card paying 2% to 5% in bonus categories could earn $2,000 to $5,000 on the same spending, depending on how much falls into bonus categories.
Mercury Compared to Other Business Cards
The Chase Ink Business Unlimited also offers flat-rate cash back — 1.5% on all purchases — with no annual fee and no foreign transaction fees. The key difference is that Chase reports to personal credit bureaus, not business bureaus, so it builds personal credit instead of business credit. Chase also has higher credit limits and faster approval for established businesses.
The American Express Business Blue offers 1% cash back on most purchases, with 3% on internet, cable, and phone services. Amex has no annual fee and no foreign transaction fees. If your business spends heavily on utilities or communications, Amex may earn more. Amex also reports to personal credit bureaus.
The Capital One Spark Cash also offers flat-rate cash back — 2% on the first $25,000 in purchases per year, then 1% after that — with a $95 annual fee. For businesses spending under $25,000 per year, the Spark's 2% rate beats Mercury's 1.5%, even after accounting for the annual fee. For higher spending, Mercury's no-fee structure wins.
Frequently Asked Questions
Can I use Mercury without opening a checking account?
No. Mercury requires you to hold a business checking account to hold the credit card. If you close the checking account, the card closes automatically. You cannot transfer the cash back to another bank — it deposits only to your Mercury account.
Does Mercury report to personal credit bureaus?
No. Mercury reports only to business credit bureaus: Dun & Bradstreet, Equifax Business, and Experian Business. The card does not appear on your personal credit report and does not affect your personal credit score.
What is the credit limit, and can I request a higher one?
Mercury typically starts with limits between $1,000 and $5,000. You cannot request a higher limit upfront. Limits increase based on your payment history and business revenue over time. If you need a higher limit when ready, you may need a different card.
How long does it take to earn cash back?
Cash back posts monthly to your Mercury checking account. There is no waiting period or redemption step — it appears automatically as a deposit each month.
Is Mercury a good card for building business credit as a sole proprietor?
Yes, if you want business credit separate from personal credit. Mercury reports to business bureaus, which helps you build a business credit profile. However, if you are a sole proprietor and do not plan to take out business loans, the business credit benefit may not matter to you.
