Thank you for posting here in the Community, @dsmart.
Let me share with you some points about the two QuickBooks Online plans and their maximum number of users.
For QuickBooks Plus, you're allowed to add up to 5 users for free and buy additional user seats up to 20. But there is no available customization of permissions for this plan.
While for QuickBooks Advanced, you can add up to 25 users for free until July 31, 2019. And the other good thing is that this plan allows you to grant new different user rights, like access to sales transactions only, expense transactions only, sales reports only, expense reports only, and so on.
Feel free to check this page for the plan comparison: Compare Plus with Advanced.
Please leave a comment below for your other concerns. The QuickBooks Community team is always here to help.
