Integrations with top accounting, payments, and ecommerce platforms provide seamless connectivity. Generous API access empowers you to customize workflows and reporting.

For US-based startups looking to separate business finances from personal with a digital-first business bank account, Mercury checks all the boxes.

Mercury Overview:

Founded by Immad Akhund in 2019, Mercury aims to cut the red tape and clunky rules and processes at legacy banks. Its Founder was frustrated with the existing banking options when running his startup Heyzap (acquired in 2016 for $45M). They’ve built a digital-first bank that caters to the needs of startups and small businesses. While they aren’t technically a bank (they partner with established banks), Mercury has everything that an eCommerce startup needs to run effectively. It’s quick and easy to apply. It wont nickel and dime you on fees - its core banking products are all free. Its dashboards are clean and modern. And it has great integrations with our recommended accounting tools. With Mercury, “things just work” as one founder said. It’s become the go-to bank for startups. Over 40% of the most recent YC batch bank with Mercury.

Why we like Mercury 👍:

Fast and easy application & approval process

Mercury’s application process is entirely online and very easy. They advertise a 10-minute application process. It took us about 30 minutes, but we’re slow, and had to hunt down our articles of incorporation. Applications are typically approved in 1-2 business days (it took our business 2 days for approval). Getting your bank account up and running should be easy, and it is with Mercury. Get your bank account quickly and focus on the other things that will actually make your business better - product and marketing.  

No fees

Unlike other banks, Mercury won’t nickel and dime you with fees. The core product - it’s online banking platform - has no monthly fees and no transaction fees. This is huge. Additionally, there is no minimum opening deposit requirement and no minimum balance requirement. You can withdraw cash through the Allpoint ATM network, and there are no fees for out-of-network ATMs (although they won't reimburse fees those ATMs might charge). Additionally, Mercury has no overdraft fees, and it doesn’t charge to send or receive checks. It also offers free domestic and international wire transfers (although a 1% currency exchange fee will be applied to non-USD transfers). Free international transfers make it easy to pay overseas merchants and will save you a ton of money.

Banking Nuts & Bolts

Mercury is great at the nuts and bolts of banking - sending and receiving money, tracking transactions, monitoring spending etc. Its dashboard is clean and easy to use, and they have a banking app (that actually works) for when you’re away from your computer. Adding users is straightforward and you can add as many as you need. Paying vendors and employees can be done through ACH, wires, checks, and foreign exchange (all without fees). It offers two access levels to permission users: one for full access (sending and receiving payments), and one for bookkeepers with view only access to transaction histories and statements. They also offer credit and debit cards that are easy to issue to employees with set spending limits, and they also make it easy to create virtual debit and credit cards. The Mercury Credit card offers 1.5% cash back, but we recommend using the Capital One Spark Cash Plus card offering 2% cash back (read our guide on business credit cards).  

High FDIC insurance amounts

With the collapse of Silicon Valley bank, FDIC insurance should be top of mind for all startups including those in eCommerce. While Mercury isn’t a G-SIB, and it isn’t even technically a bank, it uses a cash sweep program with partner banks to distribute deposits among its partner banks, so that deposits of up to $5M are FDIC insured. This is the highest FDIC insurance amount of any bank we reviewed. Typical FDIC insurance tops out at $250k. Sleep easier at night knowing that your cash is secured by FDIC insurance.


Mercury has great integrations with our recommended accounting tools (Xero and Quickbooks) that make the bank reconciliation process easier. In addition to their accounting integrations, Mercury has seamless integrations with eCommerce payment processors like Shopify, Amazon, Paypal, Stripe, and Venmo. It also has a NetSuite integration for those that use it. It’s also easy to integrate with external bank accounts with Plaid. In addition, Mercury has an API with read-write access so that you can integrate with more tools and easily create internal dashboards and automations.  

Treasury Product

While Mercury offers low interest rates on savings accounts (see ‘what we don’t like’ below), Mercury offers a Treasury product with much higher interest rates. The Treasury Product works by putting your idle cash in short term U.S. government backed securities. For amounts from $500k to $2M you will earn 4.97% Net Yield as of this writing. The yield is net of a 0.5% fee Mercury charges for the treasury product (one of the only fees they charge). You need to have at least $500,000 to qualify for the treasury product, so the bar is not low, but for those that qualify, it’s a great feature.

What we don’t like about Mercury 👎:

Low savings interest rate

Mercury’s savings account offers a measly 0.001% APR on your cash in the savings account. If you have over $500k, you can use their treasury product and earn much better interest, but for those below that you are stuck at the low rate. However, if you have less than $500k in your business bank account, we don’t think it's worth it to try to optimize for more basis points of savings account interest. The national average for savings account interest is only 0.37% according to the FDIC.  

Limited support

Some customers have complained of the limited live support with Mercury. Since Mercury is an online-first company you won't have a local bank branch that you can stop in to chat with a banker. To get help, Mercury offers live phone support from 6a to 5:30p PST from Monday to Friday. We’ve also found their email support very responsive, but if you’re looking for a personal connection with your business bank, you might want to look elsewhere. The personal relationship with your local banker might help in securing business financing.

Mercury pricing 💰:

Mercury is free to use. They don’t charge any monthly or annual fees or transaction fees. They make money by earning interest on your deposits. As we mention in the ‘what we don’t like’ section, they have a measly 0.001% interest rate on savings accounts, and they reinvest the deposits in assets that yield more than that and pocket the spread. This is how most banks make money, but others will also charge fees for their services (like money wires). We love that Mercury doesn’t charge those fees.
