If you are on a Business subscription, and you would like to upgrade the number of user licenses on your account, you may do so by going to the Billing page.
Simply click "Business" and use the arrow buttons to select the total number of user licenses you would like to have on the account.
If you are on a monthly billing schedule, the new user total will be reflected on the following month's invoice.
If you are on a yearly billing schedule, you will receive an invoice for the additional amount of users for the remainder of the year. The following year's invoice will then reflect the new total.
If you have any questions, feel free to reach out to our help center.
