Renew Your Site License
A site license may be renewed within 90 days of expiration. If a site license expires, you can no longer renew it, and if you decide to continue to use a site license for ChemDoodle, you must purchase it new.
A discount is provided to those that renew their site license BEFORE it expires, so make sure to take advantage of this! A site license renewal will extend the current site license by 12 months, so if you renew 2 months in advance, your site license will expire 14 months from the renewal.
