Annual charges?

We’re using a Premium account with annual payment, so I can’t see what costs we incurred so far. The account payment is setup for 15 users. We typically have 8-12 users per month. I have invited 26 users, 24 who have responded.

How am I getting charged? For 8-12 actual users? For 15 users? Or for 24 invited potential users?

Thanks
Bob
