Thanks for checking in with us, ChinaUser.

The option to grant partial access when adding an accountant is unavailable in QuickBooks Online (QBO). This user doesn't count towards any current user limit since they are under the Company admin user type.

For more details about this one, check out this article: Managing accountant users in QuickBooks Online. 

The only way to give a user either a full or limited access (without admin privileges) is to add them as a Standard user. Just refer to this article for the steps and details: Add, delete, or change user access.

Feel free to reply to this post if you need a hand with entering sales transactions or any QBO related. I'll be here to ensure your success. Take care always.
