Need to keep DBA for my accountant

Thank you for posting in the Community, @ind_solutions.

When a company's operating name differs from its legal, registered name, it employs a doing business as (DBA).

 We can keep "Doing Business as" to your accountant by heading to the Accounts and Settings.

Here’s how to change your business info in QuickBooks Online. 

1. Go to Settings ⚙, then Account and settings.
2. Select Company.
3. Select any item you want to update. More fields will appear when you select an area, and the question mark for each field will tell you what it’s for. See the sections below for more info on some items.
4. Select Save and Done to finish.

The following article contains more information about this: Change company name, address, email address, EIN, and privacy settings.

Optionally, manage your user roles and access to a specific task in this article: User roles and access rights in QuickBooks Online.

That should get you started in the right direction today. If you have any further questions about managing invoices emailed to customers, please leave a comment below. I'd be delighted to assist you. Have a wonderful day.
