There are 3 types of admins you can have in your system, as depicted in this article.
Each admin is billed according to the highest admin level that that admin was during the 30 day payment cycle.
I think an example explains it best:
Let’s say your billing cycle is on the first of every month. Let’s say you have a SUPER admin called Taylor in your system. As part of some changes in your organization on the 10th of the month you make Taylor an ASSISTANT admin. At that point, you will see that Taylor is pending ASSISTANT until they log in again. Once Taylor logs in the system will log them out and log them in again with their new abilities.
Since Taylor was a SUPER admin for part of the payment cycle, you would be charged according to the SUPER admin level they were at regardless of the fact that they are now an ASSISTANT admin. The following payment cycle, Taylor will be billed as an ASSISTANT admin only. They will stay at this rate until another change is made.
We thought it made sense to allow you to change an admin level at any given moment and not only at the beginning of a cycle. However, we will always bill the highest level of admin access that any given admin was during the payment cycle.
Another variable: If you upgrade Taylor the next month (next payment cycle) back to a SUPER admin, even if it is on the 29th of the month you will be charged for their higher admin level for that payment cycle as well.
Generally, it more sensible to upgrade admins as close as possible to the beginning of the payment cycle and to downgrade them as close as possible to the end of the payment cycle, so they will enjoy the extended abilities for as long as possible, and you will get the most bang for your buck.
To edit admin access for your project, click “Settings” and then “Admin Management” to change the admin levels. There’s SUPER admins, ASSISTANT admins, and VIEW ONLY admins. If you have multiple projects in your organization, you have the flexibility to give access to only one project, a selection of projects, or all projects.
Note: You must be a SUPER admin to adjust another admin’s level of access.
