Best Online Business Bank Accounts
Why Ecommerce Sellers Are Moving to Online Banks
Online business banks have captured a significant share of the small business market by eliminating the fee structures and technology limitations that frustrate ecommerce sellers at traditional banks. The typical traditional bank charges $15 to $30 per month in maintenance fees, limits free transactions to 200 to 500 per month, charges $25 to $50 for wire transfers, and runs on legacy technology platforms that make simple tasks like creating sub-accounts or generating custom reports unnecessarily difficult.
Online banks eliminate most of these pain points. No monthly fees mean your bank account costs nothing during slow months. Unlimited transactions mean you never pay per-transaction fees regardless of volume. Modern technology platforms mean you get real-time notifications, virtual cards, team permissions, and clean dashboards built for how digital businesses actually operate. The trade-off is straightforward: you give up branch access and cash deposit capabilities in exchange for lower costs and better technology.
For ecommerce sellers who receive all revenue electronically through payment processors and pay suppliers, vendors, and employees through ACH and wire transfers, the branch access trade-off is often irrelevant. If you never deposit cash and never need in-person banking services, an online bank provides strictly better banking at lower cost.
Mercury: Best Overall Online Business Bank
Mercury has established itself as the preferred business bank for startups, ecommerce sellers, and digital businesses. The platform combines fee-free banking with a feature set that rivals or exceeds what traditional banks offer at premium pricing tiers.
Account basics: $0 monthly fee, no minimum balance, unlimited transactions, FDIC insured up to $5 million through partner bank sweep network. Mercury operates through its partner banks, Choice Financial Group and Column N.A., both FDIC-member institutions.
Transfers and wires: Unlimited free ACH transfers, up to 20 free domestic wires per month, and international wire transfers at competitive rates. Standard ACH transfers settle in one to three business days, and same-day ACH is available for an additional fee. The free domestic wire allotment is a significant advantage over traditional banks that charge $25 to $30 per wire.
Cards and spending: Physical and virtual Visa debit cards with no issuance fees. Virtual cards can be created instantly for specific purposes, which is valuable for managing advertising spend across Google Ads, Facebook, and other platforms. You can set spending limits on individual cards and deactivate them instantly if compromised. Mercury also offers a corporate credit card through Mercury IO for qualifying businesses.
Team access: Granular role-based permissions let you give team members access to specific accounts and functions without exposing your full banking relationship. You can create view-only access for bookkeepers, transaction-level access for operations staff, and full administrative access for business partners.
Integrations: Direct connections to QuickBooks, Xero, Netsuite, Plaid, and over 100 other platforms through Mercury's API. The QuickBooks integration is reliable and transactions typically appear within one business day. Mercury also offers webhook notifications for real-time transaction alerts that can trigger automations in other systems.
Treasury management: Mercury Treasury automatically sweeps balances across a network of partner banks to provide up to $5 million in FDIC coverage. For businesses holding significant cash, this feature provides peace of mind that exceeds the standard $250,000 FDIC limit at a single bank.
Best for: Ecommerce sellers, startups, and digital businesses that want a full-featured banking platform with zero fees. Mercury is particularly strong for businesses that need virtual cards, team access controls, and robust accounting integrations. Read the complete Mercury review for a detailed analysis.
Bluevine: Best for Earning Interest
Bluevine stands out by paying interest on your business checking balance, which is a feature that most business checking accounts, both traditional and online, do not offer. The current rate of 2.0% APY applies to balances up to $250,000 when you meet qualifying activity thresholds.
Account basics: $0 monthly fee, no minimum balance, unlimited transactions, FDIC insured up to $3 million through partner bank network. To earn the 2.0% APY, you need either $500 in monthly debit card spending or $2,500 in monthly deposits, both easy thresholds for any active business to meet.
Interest earnings example: A business maintaining an average checking balance of $50,000 earns roughly $1,000 per year at 2.0% APY. That same $50,000 in a Chase Business Complete Checking account earns effectively nothing. Over three years, the Bluevine interest earnings total $3,000, which is real money generated with zero effort.
Line of credit: Bluevine offers a business line of credit directly through the banking platform. Qualifying businesses can access credit lines up to $250,000 with rates starting at competitive levels. Having your line of credit integrated into your banking platform simplifies cash management, as you can draw and repay from the same dashboard where you manage your checking account. This complements other business financing options.
Bill pay and invoicing: Bluevine includes built-in bill payment and invoicing tools. You can schedule vendor payments, set up recurring payments, and send invoices directly from your banking dashboard. While these tools are not as full-featured as dedicated accounting software, they cover basic needs for smaller businesses.
Integrations: QuickBooks Online, Xero, and Plaid connections for accounting automation. The integration set is smaller than Mercury's but covers the essential tools that most small businesses use.
Best for: Businesses that maintain significant checking balances and want those balances to generate returns. Bluevine is ideal for sellers who keep cash reserves in their checking account for inventory purchasing, tax payments, or seasonal buying. The interest earnings offset or exceed the cost of other business services.
Relay: Best for Financial Organization
Relay's defining feature is unlimited free sub-accounts, each with its own account number. This organizational capability allows you to implement profit-first accounting, separate funds by purpose, and maintain clear visibility into how your business cash is allocated without manual spreadsheet tracking.
Account basics: $0 monthly fee on the free plan, no minimum balance, unlimited transactions. The Pro plan at $30 per month adds features like automated profit-first distributions, advanced reporting, and priority support. Most small businesses operate comfortably on the free plan.
Sub-account structure: Create as many checking and savings accounts as you need at no additional cost. A typical ecommerce seller might create accounts for: operating expenses, tax reserves, inventory purchasing, advertising budget, payroll, owner distributions, and emergency fund. When revenue deposits arrive, you distribute funds across these accounts either manually or through automated rules on the Pro plan.
Profit-first automation: Relay's Pro plan includes automated percentage-based distribution rules. You can set rules like: 50% to operating expenses, 25% to owner pay, 15% to taxes, 10% to profit. When deposits arrive, funds are automatically moved to the appropriate sub-accounts. This automation makes profit-first accounting practical without requiring manual transfers after every deposit.
Team access: Create team member logins with permissions scoped to specific accounts. Your bookkeeper can see all accounts for reconciliation while your operations manager only sees the operating expenses account. Card spending limits and approval workflows add additional control layers.
Integrations: QuickBooks Online, Xero, Gusto payroll, and Plaid. Each sub-account can be connected independently to your accounting software, making categorization and reconciliation straightforward.
Best for: Ecommerce sellers who want detailed financial organization, profit-first accounting implementation, or clear separation of funds for different business purposes. Relay is particularly strong for businesses with multiple team members who need access to specific financial functions.
Novo: Best for Simplicity
Novo keeps business banking simple. No fees, no complexity, no learning curve. The account does what a checking account should do, receive deposits, make payments, and integrate with your accounting tools, without requiring configuration or management attention.
Account basics: $0 monthly fee, no minimum balance, unlimited transactions, FDIC insured up to $250,000. Novo operates through Middlesex Federal Savings, an FDIC-member institution.
Business perks: Novo's integration marketplace offers discounts and free access to business tools that can save hundreds of dollars per year. Partners include Stripe, Shopify, HubSpot, Gusto, and others. The specific offers change over time, but the partnership discounts can provide meaningful savings on tools you are already using or planning to adopt.
Invoicing: Built-in invoicing lets you create and send professional invoices directly from your Novo dashboard. Customers can pay invoices by card or ACH, and payments deposit directly into your Novo account. This feature is useful for B2B ecommerce sellers and service providers who invoice clients rather than processing transactions through a shopping cart.
Reserves: Novo's reserve feature lets you set aside money for specific purposes within your main account. While less flexible than Relay's full sub-accounts, reserves provide a simple way to earmark funds for taxes, inventory, or other planned expenses without opening additional accounts.
Best for: Solopreneurs, freelancers, and early-stage ecommerce sellers who want a straightforward business checking account without complexity. Novo is the right choice when you need a bank account that works reliably and does not require ongoing management attention.
How Online Banks Compare on Key Features
Monthly fees: All four charge $0. No winner or loser here.
Interest on checking: Bluevine at 2.0% APY is the clear leader. Mercury, Relay, and Novo do not pay interest on checking balances, though Mercury's Treasury product generates yield for larger balances.
Sub-accounts: Relay offers unlimited free sub-accounts with individual account numbers. Mercury offers multiple accounts on higher tiers. Novo and Bluevine are primarily single-account products with reservation features.
Virtual cards: Mercury offers the strongest virtual card capabilities with instant creation, per-card spending limits, and team assignment. Relay offers virtual cards on its Pro plan. Novo and Bluevine offer standard debit cards but limited virtual card functionality.
FDIC coverage: Mercury provides up to $5 million through its sweep network. Bluevine provides up to $3 million. Relay and Novo provide the standard $250,000. For businesses holding large balances, the extended FDIC coverage at Mercury and Bluevine is a significant safety advantage.

Limitations of Online Business Banks
No cash deposits: None of these banks accept cash deposits at branches because they have no branches. Some offer workarounds through retail deposit networks, but these typically charge fees and have daily limits. If your business handles significant cash, you need a traditional bank account for cash deposits.
No in-person service: Complex banking needs like notarized documents, official bank checks, medallion signature guarantees, and safe deposit boxes require branch access. Online banks handle these needs through mail or partner arrangements, but the process is slower and less convenient.
Limited lending products: Online banks are expanding their lending capabilities, but traditional banks still offer broader business loan options, stronger SBA lending programs, and relationship-based pricing that rewards long-term customers. If business lending is a priority, maintaining a traditional banking relationship alongside your online account provides the best access to capital.
Newer institutions: All four online banks are significantly younger than traditional banks. Mercury launched in 2019, Relay in 2018, Novo in 2018, and Bluevine in 2013. While all operate through FDIC-member partner banks, some business owners prefer the stability perception of institutions that have operated for decades or centuries.
