Highways only bills for seats that are in use. For example, let’s assume your company has 100 Intercom Users. When the Pipedrive by Highways App is installed, all 100 users potentially have access to the Pipedrive App. If, however, only 5 users install the Highways App, you will only be billed for 5 seats.
In other words, Highways only bills for seats that are actively using an App, not the total number of Intercom Users that potentially have access to the App.
Important: By default, Intercom permits any user in a workspace to which an app is installed to the access that App. This is controlled by Intercom, not Highways.
