To make your new app available for pre-order:
- From the homepage, click My Apps, select the app, and select Pricing and Availability in the left column. You’ll see the Pre-Orders section if your app has never been published on the App Store.
- Select Make available for pre-order, choose a date to release your app for download, then click Save in the upper-right corner. The release date must be at least two days in the future, but no more than 90 days in the future.
- Submit your app for review.
- Once your app is approved and you’re ready to make it available for pre-order, return to Pricing and Availability, confirm the date your app will be released for download, and click Release as Pre-Order in the upper-right corner.
In addition to offering apps for pre-orders, Apple will report pre-orders as part of the Sales and Trends section of iTunes Connect. Apple has also included an FAQ with further information about the pre-order process.
