Best way to publish the custom functionality to sell in a market


I am creating a workflow which contains more than one task. Lets say the workflow is related to SharePoint (Office 365) and there will be many feature like Retrieve site details, update a record, upload a file… etc. everything is a separate action/activity where user can call it from their main workflow.

Hope you got my point, so what is the best practice to give my work to them? Currently I have separate xaml file for each action but not sure if there is a better way to give my work to other person.
