Hi Justin. Thanks for your business (although you posted this question from an account that doesn’t have any purchases associated with it).
You can go to My Account and edit your account’s details to be the new owner’s details (name, email address, etc), or you can have them purchase their own license. If you want to consider going that route, please email us at support @ the events calendar.com from the account you purchased through and provide details about your client so we can thoroughly research this and handle it privately via email.
Thank you.
