How to Open a Business Checking Account: A Complete Guide

Opening a business checking account is one of the first, most crucial steps to setting up your business for long-term success. It’s not just about having somewhere for your business’s cash to sit; a business checking account can offer helpful financial tools from cash flow management to corporate credit cards, merchant services, and more.

The process of opening a business checking account doesn’t have to be complicated. In this guide, we’ll break down what a business checking account really is, why it matters, and how to open one without getting lost in complicated paperwork.

What is a Business Checking Account and Why Do You Need One?

A business checking account, like a personal checking account, is used to house and easily access your company's cash for day-to-day use. While a savings account is designed to earn interest on idle capital, checking accounts are primarily for everyday transactions and can include tools to help you manage spending, automate payments, organize finances, and more.

Whether your business is brand-new or well-established, a business checking account is essential for managing finances confidently.

Importance for Entrepreneurs and Small Businesses

If you’re a sole proprietor or running a lean team of just a few people, a business checking account can offer a lot of help in getting your company moving.

For sole proprietorships, a business checking account will separate your business finances from the personal. The effect of which can ease any overlap, improving the clarity of books and tax prep, helping you minimize risk of inaccurate expense reporting or liability complications.

Business checking accounts can additionally help small business owners grow their business with tools like expense tracking, automated payments (e.g., payroll), ACH and wire transfers, merchant services, and more. Additional services are dependent on the platform you choose, and can include credit cards and debit cards, cash and mobile deposits, loans, and online banking services.

For small business owners and sole proprietors, business checking accounts translate into smoother operations: you don't have to worry about mixing payments with your personal account, you can often process larger invoices with higher transfer limits, and demonstrate professionalism when dealing with clients.

What You Need to Open a Business Checking Account Online

Depending on your type of business and what business checking account you are applying for, you'll need to consider different requirements when opening a business checking account. Generally, you will be expected to provide the following:

Personal Contact Details (name, phone, email) of the business owner(s)

Business Entity Information

Business Name (legal name as registered with the state)
Business Address (physical or mailing address)
Type of Business (sole proprietorship, partnership, LLC, corporation, etc.)
Registration Certificate (dependent on state, showing your business is officially registered with the state)

Frequently Asked Questions

Can you open a business bank account without an SSN?

In some cases, yes. To do so, you’ll typically need to provide government-issued identification (like a Social Security Number (SSN) or passport). For U.S.-based businesses, most banks will require either an SSN or an Employer Identification Number (EIN), depending on your business structure. Some financial platforms, including Slash, allow you to open an account using an EIN rather than SSN, which can be especially useful for international founders.

What’s the difference between a business checking account and a business savings account?

A business savings account is typically used to store excess cash that will accrue interest for your business. A business checking account lets you handle daily business operations with tools to manage cash flow, payroll, business spending, and more.

Do I need a business account for each LLC?

Separate accounts for each LLC is best practice, though not required. If you have multiple LLCs and bank accounts, platforms such as Slash offer multi-entity support that will help you manage each entity in one dashboard.
