Capital One Spark Business Unlimited Checking

Best for: Established Businesses

Branches: 900 in eight states and D.C.

Account terms:

Why it’s a winner: Unlimited free transactions and a very high free cash ­deposit limit make this a good choice for businesses that take in and pay out a lot of money.

Caveats: The minimum balance required is high. Also, the account is meant for businesses that deposit less than $40,000 a month. If you deposit more, you’ll be moved to another account.
