What if I add or remove users?

You can add new users using "Invite users" option in the Account dropdown. 

In the Invite users popup window just add emails of the users you want to invite and press "Apply changes". Every invited user will change your current billing and your bills (either monthly or yearly) will be changed accordingly. In the end of the current month we will send you a link to the invoice with the amount of newly added users.

If you remove users, we will update the invoice in the end of your current billing cycle (either month of year).
