Choosing the wrong one can mean missing out on cashback, higher interest on idle cash, or the specific integrations that make your bookkeeping effortless.

Why Free Business Banks Are the Standard in 2026
Five years ago, a “free” business checking account usually came with strings—minimum balances, transaction limits, or hidden fees. In 2026, the landscape has shifted dramatically. Mercury, Relay, and Novo have proven that you can offer a full‑featured business bank account with zero monthly fees, no minimum balance, and robust integrations—and still turn a profit through interchange revenue and premium add‑ons. For online entrepreneurs, this means you can separate business and personal finances (see our full guide) without paying a dime.
But “free” isn’t the only consideration. The real differentiators are in the details: how many free ACH transfers you get, whether you earn interest on deposits, how well the bank plays with QuickBooks or Xero, and whether you can create multiple accounts for budgeting. This guide digs into all of that.
See how Mercury, Relay, and Novo stack up against Chase, Bank of America, and others.

If you've ever wished you could have separate “envelopes” for different business purposes, Relay is your answer.
Relay + Profit First: A Match Made in Banking Heaven

Compare Novo's built‑in invoicing to standalone tools like FreshBooks and Bonsai.
Head‑to‑Head: Fees, Limits, Integrations, and More
Let's drill down into the categories that matter most for online businesses.
Transaction Limits and ACH/Wire Fees
All three banks offer unlimited free ACH transfers—a huge win for paying contractors or receiving client payments. For wires: Mercury charges $5 outgoing, Relay charges $5, and Novo charges $0 for domestic wires (though Novo's wire limits are lower: $5,000/day for outgoing). If you frequently send wires, Novo's zero‑fee model is appealing, but Mercury's higher limits ($50K/day) are better for larger businesses.
Interest on Deposits
Winner: Mercury (via Mercury Treasury). You can sweep excess cash into a government money market fund earning ~4.5%+ APY with next‑day liquidity. Relay and Novo do not pay interest on checking balances, though Relay has hinted at an interest‑bearing savings product coming in 2026. For businesses holding significant cash reserves, Mercury's Treasury product alone can justify the choice.
Integrations with Accounting Software
All three connect to QuickBooks Online and Xero, but the quality varies. Mercury offers real‑time, automatic sync that requires zero manual intervention once set up. Relay also provides auto‑sync and is particularly good for accountants because of the multi‑account structure. Novo requires manual sync—you'll need to export transactions and import them, which is fine for low‑volume freelancers but becomes a chore at scale. If you rely on clean, automated books, Mercury or Relay are superior.
Cashback and Rewards
Winner: Mercury. The Mercury IO card is a corporate charge card (not a debit card) that earns 1.5% cashback on all spend, with no annual fee and no personal guarantee for eligible businesses. Relay and Novo offer standard debit cards with no cashback. If you spend $3,000+/month on business expenses, the IO card's cashback can add up to hundreds per year. See our Best Business Credit Cards 2026 for alternatives.
FDIC Insurance and Safety
All three are FDIC insured, but Mercury and Relay use sweep networks to extend coverage: Mercury up to $5M, Relay up to $3M. Novo provides standard $250K coverage. For businesses holding more than $250K in cash, Mercury or Relay offer significantly more protection.
Which Bank for Your Business Type?
Based on hundreds of user reviews and our own testing, here's the straightforward recommendation matrix:
Top pick: Novo – Simple, built‑in invoicing, and no wire fees. If you want interest on savings, consider Mercury. If you need multiple accounts for budgeting, Relay.
Top pick: Mercury – API integrations, Treasury interest, and the IO card. Relay is a good alternative if you prefer Profit First.
Top pick: Mercury – Deep Stripe and Shopify integrations, plus high transaction limits. Relay works well if you want to separate sales tax reserves.
Top pick: Relay – Multiple accounts let you manage client retainers, contractor payments, and owner draws separately. Mercury is a close second if you value automation over account segmentation.
Important: Cash Deposits Not Supported
None of these three banks accept cash deposits. If your business handles physical cash, you'll need a traditional bank like Chase or Bank of America. See our Chase vs Mercury comparison.
How to Open an Account in 2026
Opening an account with any of the three is straightforward and takes 10–15 minutes. You'll need:
- Your EIN (or SSN if sole proprietor)
- Business formation documents (if LLC or Corporation)
- Personal ID (driver's license or passport)
- Business website or description of your business
All three banks perform a soft credit pull on the business owner (no impact on personal credit). Approval is usually instant, though some applications go to manual review (1–2 business days). For a step‑by‑step walkthrough, see our How to Open a Business Bank Account in 2026 guide.
Frequently Asked Questions
Yes, all three have no monthly fees and no minimum balance requirements. They make money primarily from interchange fees (when you swipe your debit card) and from optional premium services (like Mercury Treasury or Relay's paid plans for advanced features). There's no hidden catch—just be aware of wire fees and international transaction fees where applicable.
Absolutely. Many online business owners use Mercury for day‑to‑day operations and Relay for Profit First budgeting, or Novo for client invoicing while keeping Mercury for interest. There's no rule against having multiple business checking accounts, and it can be a smart way to get the best of all worlds.
Mercury's mobile app is the most polished, with a clean design and full feature parity with the web app. Novo's app is also excellent and very user‑friendly. Relay's app is functional but lags behind the web experience; it's best used primarily on desktop.
Mercury offers the IO card, a corporate charge card with 1.5% cashback. It's not a traditional credit card (no APR, must pay in full monthly) but functions similarly for spending. Relay and Novo do not offer credit products. See our best business credit cards guide for alternatives.
Mercury supports non‑US founders through their partnership with Stripe Atlas (Delaware C‑Corp required). Relay and Novo currently require a US‑based business with a US address and EIN. For international entrepreneurs, Wise Business is often a better starting point.
Novo is the most welcoming to brand‑new businesses and side hustles. Mercury and Relay also accept new businesses but may ask for a business website or plan. If you're just starting, read our Finance Foundations for Online Earners to get set up correctly.
