Found vs Mercury: Pick the Right Bank for Your LLC

Key Takeaways

• Found wins for sole proprietors because it calculates real-time tax estimates and auto-saves percentages from every deposit.
• Mercury scores higher for multi-member LLCs and startups that need to manage $250,000+ in cash across different team roles.
• You can skip the $15 monthly fee on Found Plus if you don't need automated expense categorization or custom rules.
• Both platforms are fintechs, meaning your funds are held by partner banks like Evolve Bank & Trust or Choice Financial Group to ensure FDIC coverage.

On a recent r/smallbusiness thread, a consultant asked if they should ditch their traditional Chase account for an online option that actually helps with bookkeeping. They were stuck between Found and Mercury, two heavyweights that look similar but serve completely different masters.

Relay currently leads our internal rankings with an 8.2 score, but for these two, the gap is narrow: Found sits at a 7.8 while Mercury holds a 7.5. The difference comes down to whether you're a one-person army or a scaling team that needs to park $50,000 in idle cash.

Does your business have a heartbeat or a payroll?

Found is built for the person who hates their accountant.

If you're a solo graphic designer or an HVAC contractor, you likely struggle with the self-employment tax. Gov/businesses/small-businesses-self-employed/self-employment-tax-social-security-and-medicare-taxes) requires you to pay both the employer and employee halves of Social Security and Medicare. Found handles this by looking at your income and setting aside a percentage in a sub-account automatically.

Mercury doesn't do this. Mercury is built for the founder who just raised a seed round or the e-commerce business doing $2 million in revenue. It excels at moving large sums of money. While Found limits your ability to send domestic wires without a paid plan, Mercury offers them for free. If you frequently pay vendors $10,000 via wire, Mercury is the obvious tool.

Which one handles the 'envelope method' better?

Solo owners love sub-accounts. You want one bucket for taxes, one for profit, and one for operating expenses. Found lets you create these pockets, but its true strength is the automation between them. You can tell the app to move 25% of every incoming invoice to your tax pocket. This prevents the common April nightmare of a $12,000 tax bill with zero dollars in the bank.

Mercury approach is more professional but less automated for taxes.

It allows you to open up to 15 checking accounts with unique account numbers. This is perfect if you run multiple brands under one LLC or need to separate your marketing spend from your inventory capital. However, it won't calculate your tax liability for you. You have to know what to move and when to move it.

For those managing significant reserves, the Federal Reserve rate environment makes idle cash a liability. Mercury offers a Treasury product for accounts with higher balances, allowing you to earn yield on money that would otherwise sit flat. Found is far more basic here. It wants to be your bookkeeping assistant, not your investment platform.

Can you actually get your money out?

This is where the rubber meets the road for a local service business. Imagine a solo landscaper who needs to pull $400 in cash to pay a day laborer or buy supplies from a seller who doesn't take cards. Found provides access to a massive network of ATMs and even allows cash deposits at retailers like Walgreens or Walmart.

Mercury is almost entirely digital. While they issue great cards, they aren't designed for the business owner who touches physical cash. If your business involves a cash register or high-frequency ATM withdrawals, Mercury will feel like a cage. It's built for the "soft life" CEO who manages everything from a MacBook.

Before you apply

• Check your last 3 months of wire transfer volume
• Confirm your LLC filing status with the state
• Download your current 1099 or schedule C
• Verify if you need physical cash deposit access

On the application

• Use your formal EIN instead of your SSN
• List your specific industry, not 'consulting'
• Set up your first two sub-accounts immediately

After you're approved

• Link your primary payment processor like Square
• Set your automated tax withholding percentage
• Order your physical debit card for the mail

For the solo pro, Found is the better choice because it replaces a $30/month bookkeeping tool. For the 5-person agency, Mercury wins on wire costs and user permissions.
