How can we improve WHMCS?

Currently, WHMCS allows setting up free trials, but at the end of the trial period the service is automatically terminated and not renewable.

I propose enhancing this functionality so that:

- At the end of the trial period, if the client has not cancelled, WHMCS should automatically invoice and charge the client for the regular product price.
- The service should continue seamlessly into the paid billing cycle instead of being terminated.
- If the client cancels during the trial, the service should terminate as it does today, with no charges applied.

Why this would be valuable:

This is the standard free-trial-to-paid model used in SaaS and hosting industries.
- It reduces friction for clients by avoiding interruptions and re-orders.
- It ensures providers don’t lose potential paying customers due to unnecessary termination of services.
