Mercury Eligibility Requirements

The Mercury card is only open to US businesses that have an Employer Identification Number (EIN). But Mercury will not accept applications from a sole proprietorship or trust (even those with an EIN), and neither will it accept applications from companies in the money services, adult entertainment, marijuana, or internet gambling industries.

To open an account, you must submit details about your business, including a copy of its formation documents. Personal details, such as your SSN and ownership interest in the company, will also be required. There is no minimum balance requirement for a standard account. Sign-up is free. 

Moreover, no personal credit check is made, nor is your personal credit score taken into account.

If your company can maintain $250,000 or more in deposits, it will have access to Mercury Treasury, an automated cash management account that puts surplus cash balances into money market funds for improved yield and security. Mercury Treasury accounts can earn up to 2.6% interest.

Mercury IO Mastercard Fees & Features

The Mercury IO Corporate Card, like many business cards, is a charge card rather than a credit card. The card balance must be paid off in full every month. However, you can take advantage of a repayment moratorium that puts your due date up to 23 days after the close of each billing period. The amount that can be charged is determined by your Mercury account balance. 

Benefits include a free FICO score, the ability to issue unlimited virtual cards and set custom spend limits, 1.5% cash back, Treasury accounts with high APY for high balances, zero liability protection, and access to capital and venture debt investors. Mercury also offers numerous perks, including a wealth of discounts and promotional offers from a range of partnerships with business software companies, including Google Workspace integration. 

The IO card requires opening a Mercury checking account, which gives access to a suite of banking, accounting, and administrative services. Mercury is not a traditional bank, but in collaboration with The First Bank and Trust Company, offers FDIC-insured checking and savings accounts.

Since IO is a Mastercard, it will be accepted in the 210 countries and jurisdictions where the card network giant has a presence. 

There are also Mercury Credit Card apps for both iOS and Android

How Does Mercury Compare?

The Mercury card may be good enough for venture capital-backed businesses, but your company may not fit that bill. For mid-sized companies outside the VC ecosystem, the Rho card may be better. 

Like the Mercury card, the Rho card is a charge card with nice cash back rewards and no annual fee. What it does have, however, is top-of-the-line repayment options. Despite being a charge card, you will have up to 60 days to pay off an account balance. And a range of digital tools that allows you to tailor services for optimum efficiency and results. 

However, unlike the Mercury, signing up for the Rho card requires your company to maintain a minimum bank account balance of $50,000 ( $100,000 if your company is international) or spend $5,000 or more a month through corporate credit cards.
