The Create an Invoice Item task will generate a line item to charge a user upon the occurrence of the trigger event. It is usually paired with the “Generate an Invoice From Earlier Tasks” task so that both the line item is created, and the invoice is generated and sent to the user.

Note that if an existing script returns a value, it will take precedence over this workflow.

An example of this task in use is to set up a monthly invoice for a membership purchased by a user. The user would submit a request for membership, and a subscription would then be set up to invoice a set amount monthly for a specified time period.
