What the Mercury Visa Is

The Mercury Visa is a business credit card issued by Mercury, a financial technology company focused on serving small businesses and startups. It's designed for business owners who want a card tied to their company's bank account, with spending controls and real-time visibility into expenses. The card comes with no annual fee and no foreign transaction fees, which sets it apart from many competing business cards.

Mercury positions the card as part of a broader banking platform—you get the card alongside a business checking account, not as a standalone product. This means you'll need to open a Mercury business account to get the card. The card itself is a Visa, so it works anywhere Visa is accepted, but the real value proposition is the integration with Mercury's dashboard, where you can see all your spending in one place.

The card is available to sole proprietors, LLCs, S-corps, and C-corps. You'll need an Employer Identification Number (EIN) or Social Security Number (SSN) to open an account, and Mercury will run a credit check as part of the process.

Key Takeaways

  • Mercury Visa requires you to open a Mercury business checking account first—the card is not sold separately from the banking platform.
  • There is no annual fee and no foreign transaction fees, which can save money if your business makes international purchases.
  • The card integrates with Mercury's dashboard, letting you see spending, set limits per employee, and freeze cards when ready from your phone.
  • Mercury runs a credit check and verifies your business identity before approval, so the process takes a few business days rather than minutes.
  • You can issue multiple cards to employees and set spending limits on each one, making it useful for managing team expenses.

How to Open a Mercury Account and Get the Card

Start by going to Mercury's website and clicking the button to open a business account. You'll provide your business name, your legal name, your address, and your EIN or SSN. Mercury will ask what type of business you run and how long you've been operating. This information helps them assess risk and determine whether to move forward.

Next, Mercury will run a credit check and verify your identity. This typically takes a few minutes to a few hours. You may be asked to upload documents—a photo ID, a recent bank statement, or proof of your business address. If Mercury needs more information, they'll email you directly. Once verification is complete, your account opens and you can fund it when ready from another bank account.

Your Mercury Visa card ships to the address you provided during signup. Standard shipping takes 5 to 7 business days. Once it arrives, you'll set up it through the Mercury app or website. You can also request a virtual card number when ready after account approval, which you can use for online purchases before the physical card arrives.

Spending Controls and Employee Cards

One of Mercury's main selling points is the ability to issue cards to employees and control what each person can spend. From the Mercury dashboard, you can create a new card for a team member, set a monthly spending limit, restrict the card to certain merchant categories (like software or travel), and freeze or cancel the card when ready if needed.

Each employee card is tied to your main Mercury account, so all spending flows through your business checking account. You can see every transaction in real time, tag expenses by project or department, and export reports for accounting. This level of control is useful if you want to give team members purchasing power without the risk of overspending or fraud.

You can also set daily spending limits, weekly limits, or monthly limits depending on your business needs. If an employee tries to spend beyond their limit, the transaction will be declined. You receive notifications for every card transaction, so you stay aware of company spending as it happens.

Fees and Rewards

Mercury Visa charges no annual fee, which is a significant advantage over many business credit cards. There are also no foreign transaction fees, so if your business buys from international vendors or pays suppliers overseas, you won't pay a percentage markup on those purchases.

The card does not offer cash back or travel rewards. Mercury's focus is on spending visibility and control rather than rewards programs. If earning rewards on business purchases is important to your decision, you may want to compare Mercury against cards like the Chase Ink Business Preferred or the American Express Business Gold, both of which offer points or cash back.

Mercury does charge standard fees for things like wire transfers, ACH transfers, and check printing through the Mercury platform, but these are separate from the card itself. The card itself has no hidden fees—you pay what you spend, nothing more.

How Mercury Visa Differs From Traditional Business Cards

A traditional business credit card from a bank like Chase or American Express is a credit product—you receive a bill at the end of the month and pay interest if you carry a balance. Mercury Visa works differently. It's a debit card tied directly to your Mercury checking account, so money comes out of your account when ready when you swipe or use it online. You cannot carry a balance or build credit history with it.

This matters for two reasons. First, you cannot spend money you don't have, which eliminates the risk of debt but also means you need cash in your Mercury account to use the card. Second, Mercury does not report card activity to the credit bureaus, so using the card won't help you build or improve your business credit score. If building business credit is a goal, a traditional credit card is a better choice.

Mercury's strength is real-time visibility and control. You see spending when ready, can freeze cards in seconds, and can set limits that actually prevent overspending. Traditional cards give you a bill at the end of the month with no way to stop a purchase before it posts. For businesses that prioritize expense management over credit building, Mercury is often the better fit.

What Happens During the Signup Process

Mercury's signup process is faster than a traditional bank but slower than some fintech competitors. You'll complete the initial process in about 10 minutes. Mercury then verifies your identity and business information, which usually takes 1 to 2 business days. If they need additional documents, they'll contact you by email.

Once your account is approved, you can fund it when ready and start using a virtual card number for online purchases. Your physical card ships within 5 to 7 business days. You don't need to wait for the physical card to arrive to start using Mercury—the virtual card works right away for e-commerce, subscriptions, and other online payments.

If Mercury cannot verify your information or has concerns about your business, they may decline your process. This is rare, but it can happen if you have a very new business, poor personal credit, or if Mercury cannot confirm your business identity. If you're declined, Mercury will tell you why and you can reach out to their support team to discuss options.

Security and Fraud Protection

Mercury Visa includes standard fraud protection—if someone uses your card number without permission, you can report it and Mercury will investigate. Because the card is tied to your Mercury account, you can also freeze it when ready from the app, which stops any further charges when ready.

For employee cards, you have additional control. If you suspect an employee's card has been compromised, you can freeze or cancel it from your dashboard without waiting for a phone call or email. You can also see the exact transaction that triggered your concern, which helps you determine whether it was fraud or a legitimate purchase.

Mercury uses encryption and multi-factor authentication to protect your account login. You can enable two-factor authentication on your account, which requires a code from your phone or email before anyone can access your account. This is especially important if multiple people have access to your Mercury account.

Frequently Asked Questions

Can I use Mercury Visa for personal expenses?

No. Mercury Visa is a business card tied to a business checking account. Using it for personal expenses can violate your business structure and create tax and accounting problems. Keep business and personal spending separate.

What if I don't have an EIN?

You can use your Social Security Number instead. Mercury accepts both. If you're a sole proprietor without an EIN, your SSN is sufficient to open an account and get a card.

Can I transfer my existing business checking account to Mercury?

No. Mercury is a separate banking platform. You'll need to open a new Mercury account and transfer funds from your existing bank if you want to use Mercury. Some businesses keep both accounts open—one at their traditional bank and one at Mercury.

Does Mercury Visa help build business credit?

No. Because Mercury Visa is a debit card, not a credit card, it does not report to business credit bureaus. If building business credit is important, you'll need a traditional business credit card instead.

What happens if I close my Mercury account?

Your Mercury Visa card will stop working. Any pending transactions may still process, but new charges will be declined. You'll need to withdraw any remaining funds from your Mercury checking account before closing it.
