I have QB online Essentials. What exactly can a "billableuser" see on QB and do on QB?

Welcome back to the QuickBooks Community, cindynicks1221. 

I'm here to share additional details about how users work in QuickBooks Online.

Billable user role that counts toward your user limits are the Primary admin, Company admin and Standard User. You can give each user certain permissions to do specific tasks. You can also choose what they can see and do within different areas of QuickBooks, such as customers and sales or vendors and purchases.

To create users:

1. Go to the Gear icon, then Manage Users.
2. Press Add User.
3. Select the User Type you want to create.
4. Enter your User's name and email address, then hit Save.
5. Your User will quickly get an email. It'll have your business's name and a link that includes Ready to get started? Let's go! Have your User press the link to finish the process of getting connected to your account.

For more information about the types of users, you can check out this article: User types in QuickBooks Online. This also includes the limitations of each user.
