I'm happy to guide you on managing user permissions in QuickBooks Online (QBO).
To begin with, are you trying to customize the user permission? If so, please know that QuickBooks Online has a feature wherein you can manage User roles and access rights.
Here are the key roles:
Primary Admin: This user has access to every part of the QuickBooks account and can manage all users and admin tasks.
Company Admin: Similar to the primary admin, they can’t edit or remove the primary admin’s access.
Standard All Access: Users in this role can access everything related to customers, sales, vendors, purchases, and more. They can also manage payroll if it’s enabled.
In-House Accountant: This role provides access to bookkeeping and accounting tools, financial reports, and other features, excluding payroll and user management.
