If you are a web developer and have purchased the Pro plugin on behalf of a client, the Freemius platform that we use has the capability for you to transfer billing to the client.
To transfer the subscription to your client, first login to https://fullworks.net/account/ ( all Freemius distributed products, not just those provided by Fullworks can be managed here )
Navigate to Renewals and Billings – select the plan and select ‘Cancel Auto-Renew’.
Then ( with the plugin still active on your website – do not deactivate ) navigate to Websites and find the website and click on the plugin and expand and click on ‘Transfer Billing to Client’.
An email with a direct purchase link will be sent to your client so they can associate their billing with the plugin while keeping the license and management on your end. You will get a notification when this will happen.
