Your Thinkbox Customer Portal account will be created automatically after you purchase your first Usage Based Licensing product, and it will be tied directly to this Thinkbox Store account. Your Customer Portal will allow you to monitor your usage based licensing.
Note that render time from two separate Customer Portal accounts can not be combined. If you or your company already have an existing Customer Portal, and you would like to tie a new Store account to it, please contact Thinkbox Support and we will create your Store account for you.
