When Publishing an App for Apple you must ensure you have a Developer account that is the same name of the app, or the name of the owner of the app. For example if you are publishing an App called "Joe's Pizza" then the Apple developer account needs to be in the name of "Joe's Pizza" Alternatively you can have the developer account in the name of the owner of Joe's Pizza - for example Joe Smith.
Each one of your apps has to have its own developer account. To enroll in the Apple Developer Account click here:
After you have setup your developer account, you will need to add our team as an admin so that we can submit the app for you. Please add: firstname.lastname@example.org.
For Android Apps you are able to publish all of your Apps into 1 Developer Account.
