Amai PreOrder Manager + Notify

Asides from a display thing with a ribbon explaining the button/functionality, the app works great. It requires a proper installation from Spur-IT, which will be performed in a timely manner and the rest is history. You can make it as functional as you need, creating tags for platform and inventory management sorting. The pool of pre-orders will also be stored at an app level, so you will always have a backup just in case. Support has been always on point, attending inquiries and issues promptly. Would definitely recommend this app.
