Whatever functionality that you like Alexa to help you with, we will develop it for you.
When your skill is ready to be deployed, you can choose to make it public ( available for all users in the amazon store ), or you can choose it to be private ( use it alone and won’t be featured in the amazon store ).
If you choose to deploy your skill as public, you choose if it will be available for your users for free or to charge money by either:
Selling real products to the users inside your skill.
Providing monthly subscriptions.
Selling consumable content that can be bought repeatedly.
Making your users buy the skill from the start only once and they can access the content forever.
