What To Look For In A Small Business Bank Account

Not every small business bank is alike, and what works for one business may not work for another. Overall, the best business bank accounts have the following features. 

  • Low Fees and Flexible Requirements: You’ll want a bank that features low monthly maintenance fees, minimum balance requirements, ATM fees, and overdraft charges, or ideally, none at all.
  • Plenty of Account Features and Services: It’s not enough to just have a business bank account. Instead, look out for the features and services that will make managing your money easier, including instant check deposit, bill payment services, transfer services, and more. 
  • High-Yield Savings Account or Interest-Bearing Checking Account: The better rates your small business bank offers, the more money you’ll earn on your cash reserves. 
  • Unlimited Transactions: In general, you want a bank account that allows you to make deposits, withdrawals, payments, or transfers as frequently as you need—without imposing additional fees. 
  • Quality Customer Service: Should you run into any issues concerning your finances, you’ll need to know the customer service team is professional, easily accessible, and willing to help. 
  • Introductory Bonus Offers: Some banks will offer a cash bonus for opening a business checking account. If possible, seek out the best banking offer.

They’re the single most active SBA 7(a) lender in the country, having approved $369,181,900 in small business 258 7(a) loans.

Both business banking accounts come with unlimited ATM fee reimbursements and zero transaction fees for the first 50-200 transactions per month. Opening an online business checking account requires no credit check and can be done entirely remotely.

Celtic Bank 

Celtic Bank is an entirely online bank. Small business owners can also access money market accounts, savings accounts, and CDs. 

Celtic Bank offers a large variety of business loans and other business financing solutions – including business credit cards. Because they’re a bank, though, qualifying can be difficult and time-consuming. 

Many of the small businesses Celtic Bank works with include healthcare companies, hotels, C-stores, gas stations, car washes, and more. 


Novo is an entirely online business banking platform. It offers some of the best business bank accounts for LLCs and other small businesses. These include free checking accounts and integration tools.

Business banking accounts feature no monthly maintenance fees or minimum balance requirements. There are also no ACH transfer fees, incoming wire fees, or transaction fees. Plus, Novo guarantees unlimited ATM fee reimbursement. 

Perhaps the biggest perk to banking with Novo is its rich integrations with tech tools like Slack, Wise, Xero, Stripe, Shopify, and QuickBooks. These integrations allow small business owners to track invoices, send invoices, accept payments, organize transactions, integrate their workflow, and more. If you find yourself sharing financial details with your team or accountant frequently, then this could be a game changer.
