The 5 Best Small Business Banks in Oklahoma

These banks offer small businesses no or low-cost business checking accounts designed to simplify operations and boost efficiency. From powerful integrations that save hours on monthly bookkeeping to tailored lending options that support growth, these institutions are built to empower your business.

1. North One

Interested in digital-first banking? North One takes your financial management entirely online, offering an intuitive mobile and online platform that’s perfect for modern entrepreneurs, freelancers and startups. Their flagship offering is their business interest checking, which offers up to 3% APY on your balance — that’s 38x the national average.

North One acts as a virtual financial command center. Their platform comes packed with features like an envelope budgeting system and team banking capabilities that let you control who has access to what. Plus, it plays nicely with all your favorite business tools: whether you’re a QuickBooks enthusiast or a Xero user, North One’s numerous integrations have you covered.

When it comes to checking accounts, North One keeps it refreshingly simple with two options:

  • Standard: This plan is a fee-free option with all the essentials: 2.5% APY, 1.5% same-day ACH payments, free digital bill payments, $1 physical checks and free incoming domestic wire transfers. You’ll also get a monthly allowance of one free cash deposit and two ATM withdrawals — perfect for businesses with modest cash handling needs.
  • Plus: This $20/month plan is the next tier up. It offers 3% APY and eliminates fees on same-day ACH payments and incoming domestic wire transfers while tripling your ATM withdrawal limit to six and boosting your free cash deposits to three per month. Plus members also get their own personal support team, including an onboarding assistant to get you started and a dedicated customer success manager to keep things running smoothly.

Just remember: North One’s banking options are almost entirely online. If you’re the type who likes face-to-face banking relationships, their digital-first solutions might not be your cup of tea. But if you’re ready to try something new, North One offers low fees, powerful financial tools and stellar customer service.

2. BancFirst

If you’re looking for a more traditional bank with a range of services, BancFirst might be a good option for you. As Oklahoma’s largest state-chartered bank since 1889, it operates 104 branches across 60 communities and has over 250 ATMs, including interactive teller machines (ITMs) for face-to-face banking. Recognized for its stability, BancFirst has ranked among the nation’s safest banks for 18 consecutive years and earned a spot on Forbes’ list of America’s Best Banks for 2024.

BancFirst provides online banking with real-time account access, fund transfers, bill payments, and strong security measures. Its Business Essentials Checking Account is ideal for small businesses and non-profits with low transaction volumes. The account allows up to 200 free monthly transactions, with a $0.40 fee for each additional transaction and a $15 charge for a third account. It includes a free business debit card, payroll services, and remote deposit capture.

BancFirst is also Oklahoma’s top SBA lender, offering SBA 7(a) loans up to $5 million and SBA 504 loans up to $12.5 million. These loans cover working capital, acquisitions, and real estate purchases. For larger businesses, BancFirst provides commercial loans, including working capital lines, term loans, energy loans, and agribusiness loans that support Oklahoma’s agricultural sector.

Additional services include point-of-sale terminals, mobile processing, and e-commerce integrations. BancFirst also offers business credit cards with flexible payment options, rewards, and fraud protection. However, the bank does not provide business savings accounts, so businesses seeking to earn interest on excess funds will need another option. While BancFirst’s services are comprehensive, they may not be tailored to very small or niche businesses outside its core industries. Still, its strong reputation and wide range of offerings make it a solid choice for Oklahoma businesses.

3. Bank of Oklahoma

Bank of Oklahoma (BOK) is a regional financial institution with over 100 years of experience serving businesses and consumers. Headquartered in Tulsa, it operates more than 50 branches, primarily in Tulsa and Oklahoma City.

BOK’s business checking options cater to different needs. The Business Access account is a simple, low-cost option with no monthly service fee, unlimited transactions, and free online and mobile banking. However, it charges fees for paper statements ($2 per month) and cash deposits exceeding $3,000 per month. The Business Advantage account is geared toward businesses with complex cash flow needs, offering free incoming domestic and international wires. It has a $30 monthly service fee, which can be waived by maintaining a $15,000 minimum balance.

They offer Business Savings and Business Investor Fund accounts for businesses looking to grow their savings. The Business Savings account has a $2 monthly fee, waived with a $300 average balance.

To support cash flow, BOK offers Exchange, a platform for managing payments and transfers, along with business credit cards featuring cashback on purchases like dining and office supplies. However, there are potential drawbacks, including fees for paper statements and cash deposits beyond the monthly limits. Businesses may also face challenges meeting balance requirements to waive fees. Despite these limitations, BOK remains a strong option for small businesses, especially those in Tulsa and Oklahoma City.

4. Oklahoma’s Credit Union

Oklahoma’s Credit Union (OKCU) is a local financial cooperative headquartered in Oklahoma City, Oklahoma. Established in 1954, OKCU has served Oklahomans for over 70 years. The credit union operates five branches across Oklahoma, and account holders have access to a network of ATMs and 24/7 digital banking tools. 

Membership in Oklahoma’s Credit Union is open to individuals who live, work, worship, or attend school in the Oklahoma counties of Cleveland, Canadian, Oklahoma, Grady, Logan, Lincoln, McClain or Pottawatomie. Employees of any Oklahoma state agency that does not have its own credit union are also eligible to join.

OKCU offers a range of simple but straightforward business banking products. Their business checking accounts include Free Business Checking, which requires a $100 opening deposit—but there’s no monthly fee or minimum account balance. Business+ and Nonprofit Checking both have a $500 minimum opening deposit and account balance to waive a $10 monthly fee, and earn interest over $10,000. 

Business savings accounts are also available, including a standard Business Savings Account and a Money Market Savings Account, both offering tiered interest rates where higher balances yield increased earnings. Additionally, OKCU provides Business Certificates with flexible terms ranging from 6 to 60 months, guaranteed rates, and no risk to the principal balance. A certificate laddering strategy is also available to help businesses maximize returns while maintaining liquidity. For businesses that require financing, OKCU offers several loan options, including commercial real estate loans, rental property loans, commercial auto loans and SBA loans. 

While OKCU offers a range of services, there may be some limitations in terms of specialized offerings or industry-specific financial products. Nonetheless, Oklahoma’s Credit Union remains a reliable credit union for those who want localized, member-focused banking.
