How do I hand over a development store after successfully testing it?

First, go to stores in the Partner Dashboard. Second, click on Transfer Store Ownership to select the development store you want to transfer. Then open the Transfer Store Ownership Dialogue Box to add your client as your staff member. Then click Transfer Store on the store's page in your Partner Dashboard under the Managed tab. The new owner will receive an email inviting them to create an account and select a plan. Until they accept it, the store status will show "paused."
