Hi. I am trying to activate a Privacy setup to restrict access for our other users to our management accounts. Can anyone assist ?

Yes, QuickBooks Online (QBO) Plus has that ability, @Mody. I'm here to share some insights about those available authorizations and how you can arrange them for your five users. 

You can set different access rights to your five users. I'd suggest using the "Standard user" type since they can work with customers, sales, suppliers, and expenses. Here's the summary of its available features in the program: 

• All access (customers, sales, vendors, and purchases)
• Limited (customers and sales)
• Limited (vendors and purchases)
• Limited (customers, sales, plus vendors and purchases)
• None (submit time sheets only)

For more details on what this user type "can" and "can't" do, see this article's Standard user section: User Types In QBO. 

When you're ready, you can add your five users to QBO and assign their appropriate permissions. I'll guide you how. 

1. Go to Settings (⚙) at the upper right and select Manage Users under Your Company. 
2. Click Add user.
3. Choose Standard user and click Next. 
4. Select the appropriate access rights. 
5. Click Next. 
6. Modify the user settings and select Next. 
7. Enter their contact info.
8. Tap Save. Repeat the process for the other four users. 

The screenshot below shows you the last five steps. 

Once done, the users will get emails and have them accept the invitations. For the detailed steps, let them follow this article: Adding, Deleting, Or Changing User Access. Then, have them go to Step 2 under the Add a QuickBooks Online user section. 

Aside from Standard users, you can add them as company admins, Reports only, and Time tracking only. Just go back to the Manage Users tab to perform this activity. On this page, you can also edit their access rights, view their activities, and delete them (see the screenshot below).
