A "small business checking account" is a type of bank account.

Most bank accounts fall into one of two categories:

• Checking accounts are for money that you need to spend. You can take money out by writing checks, or by withdrawing money from an ATM.
• Savings accounts are for saving money. You can earn more interest for the money that's in a savings account. You can take your money out of savings, but the bank may have restrictions on how often you can move money in and out of savings.

Banks offer "small business checking accounts" to businesses. These accounts have different rules than personal bank accounts.
