Hi there, @accountdept-staf, 

You won't be charged for an additional standard user since this is a feature that comes along with your subscription. It'll only count toward the allowable user limit below: 

• Billable users: 5
• Accountant users: 2

For more details, check out this article: How Many Users Can I Set Up?. 

The available user types in the program are Master admin, Company admin, Standard, Time tracking only, and Reports only. There are different permissions for each one of them. 

Also, I recommend going to the Manage Users page. From there, you can edit the user access rights, view their activities, or delete them. 

I'll be around to help if there's anything else you need. Keep safe always.
