Feature Add-On

An add-on is an additional flat fee that can be included with a price plan. Add-ons for a price plan can be selected when subscribing a customer to that plan, and only the ones included in the subscription end up on the customer’s invoice. For example, add-ons can be used to let customers pay for prioritized phone support as part of their subscription.

Add-ons are charged at the end of the billing cycle (or at the beginning with upfront billing) and are included in all invoices as separate line items. Add-ons can be charged at a frequency of once per billing cycle, or once per subscription (see the screenshot below).
