Is it possible to add additional accounts to my current one that will be attached to the same bank account. The others are DBAs of the first one. Does this work in QBO?

Yes, @fallline, it's possible as long as it's a separate subscription. I'll go over some details and get you going.

You'll need to add a separate QuickBooks Online (QBO) company using the same bank account. However, it's advisable to register the new business under an LLC or S-Corp. I also suggest seeking guidance from an accountant for further advice. You can find an accountant by visiting this link: Find an Accountant.

Refer to this article for the process of adding a new company: Create or add another company file to QuickBooks Online.

For future reference, here's an article that can help you manage your accounts in QuickBooks: Merge duplicate accounts, customers, and vendors in QuickBooks Online.

Never hesitate to ask additional questions as you get your accounts added. This process can be crucial, so I want you to feel fully supported.
