Specific billing logic governs the automation for many of your business's most important tasks, including ordering, payments, and provisioning.
The Products/Services tab in the Client Profile lets you view and manage client services.
If you enable cancellation requests, clients can request cancellation or termination of their services from within the Client Area.
The system is unexpectedly terminating services (for example, hosting accounts).
Cancel a service for a specific client immediately in the Admin Area. After you cancel a service, WHMCS will not generate further invoices.
Schedule a service to terminate at the end of the current billing period. When you do this, the system will cancel any unpaid invoices.
