Before membership orders can be created, you must have a release and packages need to be created for members. Depending on how you configure the release, the packages may be customized by members, then those packages go through an order batching process to create the orders. If customers need to select their products as part of creating a membership, then a release needs to be created and published. 

Release types

There are two types of releases, based on the tier types provided by Bloom Commerce. Traditional and Allocation releases. What the video below to learn more about creating and configuring releases.
