Can I set up two customer groups within one company

Why do you need to do that? What kind of business do you run?  

Hi there, s.sorenson@mac.c.

Thank you for joining our community. I can confirm things about setting up customers in QuickBooks Online.

Yes, you can use customer types for grouping customers into different segments (see screenshot below). This article will show you the process and how to run a report: Set up and assign customer types in QuickBooks Online.

If you have duplicate customers, you can also merge their profiles. I've attached a link you can visit to view the detailed steps in QuickBooks: Add and manage customers in QuickBooks Online.

Let us know if you still have more questions about managing customer profiles by leaving a reply. We'll be right here to help. Take care, and have a great day.
