Digital Publishing Suite is available in both a Professional Edition and an Enterprise Edition. Pricing for the Professional Edition is based on a monthly Platform fee--which lets publishers access the Digital Publishing Suite and create apps for all of their titles and publications--as well as a small Service Fee for each publication downloaded by a reader. The Enterprise Edition is a custom, multiyear platform agreement that includes access to APIs for integrating back-end publishing services such as subscription management, print fulfillment, and e-commerce.
