Any way to prevent or automatically handle Pending Upgrade Order Cancelled?

[cloudmate]

We often create upgrades as Admin. In some cases the following month's invoice is created for the product prior to the client paying the upgrade invoice, which results in the upgrade being reversed and the upgrade invoice cancelled. We don't want to have the upgrade cancelled automatically in this scenario. We'd want the upgrade to remain and the new invoice to include the quantities from the upgrade. Is there a way to handle this? If this can't be done we'd at least want to prevent the Pending Upgrade Order Cancelled email template from being sent to the client (just sent to the Admin).

Since a renewal invoice is generated using the pre-upgrade pricing, the upgrade invoice becomes invalid once the renewal invoice is generated. So it is not possible to not cancel the invoice or to generate the renewal invoice using the upgraded prices if the upgrade invoice has not been paid yet. You can disable the email template to disable the email completely.

Thanks @WHMCS Sachin, we do want the email sent to admin so we can handle when this case happens. We just don't want it sent to the client.
