Pre-orders for print books:
Any title with a future on-sale date or publication date in Ingram metadata will show up as a pre-order through Aerio.
If you are providing on on-sale date, it is important that this reflects the date your title will be available to ship to consumers.

If your ebook has already been uploaded and you need to change the "Publication Date," go to the title's "Book Dashboard" under "My Inventory" and then choose "Retail"
