I just opened a quickbooks small business checking and I'm ordering checks..what is the bank name for my checks??

Welcome to the Community, lake.

The bank name for the checks is Green Dot Bank. It's a partnership with QuickBooks Online. Green Dot is a payment platform that you can use when sending money using the Green Dot app. Once your customers pay you using this app, the payment will be deposited into your Green Dot bank account. 

Additionally, I'll be leaving these articles to help you in the future :

• Record and make bank deposits in QuickBooks Online
• Bank connectivity

Should you need additional assistance in your checks in the QuickBooks Online, feel free to include them in the comments below. Stay safe!
