# The Best Business Bank Accounts for Startups in 2026

> A fee-by-fee comparison of Mercury, Relay, Bluevine, Novo, Found, and Rho to help founders pick a business bank account without getting surprised by the fine print.

Published: 2026-09-17 · By: The Finance Desk

Opening a business bank account used to mean walking into a branch of whichever bank held your personal checking. In 2026 that default has quietly disappeared. Most startups and solo founders now open with a fintech that partners with an FDIC-insured bank behind the scenes, and the differences between those fintechs are not cosmetic. They show up in wire fees, savings yield, how many sub-accounts you get, and whether the account talks to QuickBooks or Xero without a workaround.

We compared six accounts that repeatedly come up in founder recommendations: [Mercury](https://mercury.com/?utm_source=guides.reviews&utm_medium=referral&utm_campaign=best_list), [Relay](https://relayfi.com/?utm_source=guides.reviews&utm_medium=referral&utm_campaign=best_list), [Bluevine](https://www.bluevine.com/?utm_source=guides.reviews&utm_medium=referral&utm_campaign=best_list), [Novo](https://www.novo.co/?utm_source=guides.reviews&utm_medium=referral&utm_campaign=best_list), [Found](https://found.com/?utm_source=guides.reviews&utm_medium=referral&utm_campaign=best_list), and [Rho](https://www.rho.co/?utm_source=guides.reviews&utm_medium=referral&utm_campaign=best_list). None of them charge a mandatory monthly fee for their base tier, which makes the real comparison about what you get once you outgrow that tier, and about the fees that only show up when you actually use the account.

## Mercury

Mercury is the account most venture-backed startups open first, largely because it was built for exactly that: incorporated companies that need clean bookkeeping, virtual cards for a growing team, and an API to wire the account into internal tools. The free tier has no monthly fee, no minimum balance, and no charge for domestic wires or ACH, with FDIC coverage extended to $5 million through its multi-bank sweep network rather than the standard $250,000. Mercury Plus runs $29.90 a month and adds ACH-debit invoicing and unlimited 1099 filings, while Mercury Pro at $299 a month adds a dedicated relationship manager and NetSuite categorization. The tradeoff is that Mercury is not a bank itself, and treasury features (with yield up to roughly 3.67%) only unlock once a balance crosses $250,000, so very early-stage accounts earn nothing on idle cash.

## Relay

Relay is built around the Profit First cash management method, so its core feature is not a single account but up to 20 checking sub-accounts you can use to automatically bucket revenue, taxes, and payroll. The Starter plan is free but charges $5 for an outgoing domestic wire, a fee that disappears on the $30-a-month Grow plan and the $90-a-month Scale plan (discounted from $120). Savings APY scales with plan, from 1.11% on Starter up to 3.00% on Scale, and FDIC coverage runs up to $3 million through Thread Bank. Relay's QuickBooks and Xero integrations sync on a 24-hour cycle, which is fast enough for most small teams but worth knowing if you need same-day reconciliation.

## Bluevine

Bluevine is the strongest choice for founders who want their operating cash to actually earn something. The Standard plan is free and pays 1.3% APY on balances up to $250,000 if you meet monthly activity requirements, and the $95-a-month Premier plan raises that to 3.0% APY on the full balance with no cap. There is no charge for incoming wires, ACH, or in-network ATM use, and the Plus tier at $30 a month sits between the two. The catch is that the higher APY tiers are only worth the monthly fee once your average balance is large enough that the extra yield outweighs the subscription, so Bluevine rewards startups holding real cash reserves more than pre-revenue ones.

## Novo

Novo is aimed squarely at freelancers and very small businesses that want simplicity over sophistication. There is no monthly fee at any tier, no minimum balance, and ATM fees are refunded up to $7 a month worldwide. Built-in invoicing lets you accept ACH, Venmo, PayPal, Stripe, or Square payments without a separate tool, and it connects natively to QuickBooks, Shopify, Wise, and Zapier. Because Novo partners with Middlesex Federal Savings rather than a multi-bank sweep network, FDIC coverage tops out at the standard $250,000, and there is no interest-bearing option at all, which makes it a poor fit once a business is holding significant cash.

## Found

Found is less a bank account than a full back office for a solo self-employed worker: it estimates and sets aside quarterly taxes automatically, tracks write-offs, and lets you invoice clients and pay contractors from the same app. The base account is free with no monthly or overdraft fees; Found Plus ($35/month or $315/year) and Found Pro ($80/month or $720/year) add deeper tax tools and reporting. The tradeoff is that Found is built for a single owner, not a team, and its fit gets noticeably tighter the moment you add a business partner, hire an employee, or need the account to sync cleanly with external accounting software.

## Rho

Rho skips subscription pricing entirely and instead charges only for specific transactions, mainly a $15 SWIFT fee and a 1% conversion fee on international wires; domestic ACH and wires are free. It bundles checking, treasury, bill pay, corporate cards, and approval workflows in one system, and its Business Savings account carries FDIC coverage up to $75 million, far beyond what any competitor here offers. Rho is explicitly not available to sole proprietors or unincorporated businesses, and it makes the most sense for venture-backed companies with a finance function already processing real invoice volume, not first-time founders opening their first account.

## At a glance

| Account | Monthly fee (top tier) | Free plan wires | Savings APY | FDIC coverage | Best for |
|---|---|---|---|---|---|
| Mercury | $0 / $29.90 / $299 | Domestic wires free | Up to ~3.67% (Treasury, $250k+ only) | Up to $5M | Incorporated startups needing an API |
| Relay | $0 / $30 / $90 | $5 on Starter, free above | 1.11% to 3.00% | Up to $3M | Teams using Profit First budgeting |
| Bluevine | $0 / $30 / $95 | Incoming free; outgoing may charge | Up to 3.0% (Premier, no cap) | $250K | Founders who want yield on cash |
| Novo | $0 | Included | None | $250K | Freelancers wanting simplicity |
| Found | $0 / $35 / $80 | Free ACH | None | $250K | Solo self-employed workers |
| Rho | $0 (transaction fees only) | Domestic free | Available via Treasury | Up to $75M | Funded startups with a finance team |

## How to choose

If you have just incorporated and expect to raise or spend investor money, Mercury's free tier and API access are the default for a reason. If you are bootstrapping and want your account to enforce a savings discipline, Relay's sub-accounts do that automatically. If your business is sitting on a real cash cushion and you want that money working, Bluevine's Premier APY beats what a traditional bank will offer on a checking balance. Solo freelancers who want to skip separate invoicing and tax software altogether are better served by Novo or Found, and Found specifically if quarterly tax withholding is the biggest pain point. Rho only makes sense once you have transaction volume and a finance person who will use its approval workflows; opening it as a first account is overkill.

## Verdict

There is no single best business bank account, but the differentiators are clear once you know what to price in. Wire fees and APY tiers matter most as your balance grows; FDIC sweep coverage matters most if you plan to hold seed or Series A cash in the account rather than a separate money market fund; and built-in invoicing or tax tools matter most for a solo operator who would otherwise be paying for two or three extra pieces of software. We would open Mercury as a first account for most incorporated startups, and layer in Bluevine or Relay once cash balances are large enough that yield and sub-accounts start to pay for themselves.

## Frequently asked questions

### Is Mercury or Relay an actual bank?

No. Both are financial technology companies that partner with FDIC-insured banks to hold deposits. Mercury works with a network of partner banks to extend coverage up to $5 million, while Relay partners with Thread Bank for coverage up to $3 million. Your deposits are insured through the partner bank, not the fintech itself.

### Which of these accounts pays the highest interest on cash?

Bluevine's Premier plan, at $95 a month, pays up to 3.0% APY on the entire checking balance with no cap. Relay's Scale plan matches that 3.0% rate but only on its separate savings sub-accounts, not on checking. Mercury's yield is highest in absolute terms but is restricted to its Treasury product, which requires a $250,000 minimum balance.

### Do I need an LLC or corporation to open one of these accounts?

Mercury, Relay, Bluevine, and Rho require a registered business entity, such as an LLC or corporation. Novo and Found are more flexible and will open accounts for sole proprietors operating under their own name, which is why they tend to suit freelancers who have not formally incorporated.

### Are there hidden fees I should watch for with these accounts?

The most common surprise fees are outgoing wire charges on free tiers (Relay charges $5 on Starter) and currency conversion fees on international payments, which run about 1% at both Mercury and Rho. Read the fee schedule for outgoing wires and foreign currency specifically, since domestic ACH is free almost everywhere but wires and international transfers are where these accounts differentiate.
