Here is the breakdown of fees & charges for Magento Mobile.
One-time Setup Fee: $799
This is to setup your account and launch your app in the iTunes marketplace
Recurring Maintenance Fee: $699 (or pay $69/month)
Magento submits your native app and maintains/supports your application code in the iTunes marketplace. This recurring fee must be paid upfront in addition to the setup fee.
Resubmission fee: $99 per resubmission
This a rare fee and it only pertains to any changes you make to the fields under the “Submission” tab after you’ve already submitted an app. Any changes you make to any of the other tabs, including “Design”, “Content”, etc. do not require a submission. We charge this fee because any change you make to the items under “submission” are core to your app itself and they must be approved by the iTunes App Store—an operational process that Magento Manages for you.
Additional Features: To Be Determined
In the future, Magento may release enhanced features that require additional investment. This might include advanced shopping options or unique ways to communicate with your users.
