Paid Priority Support

With the Paid Priority Support power tool, you can restrict your clients from creating High priority tickets, unless they pay a fee.
When a client sets the priority to High, the ticket is created, but the priority is set to Medium.  They are then redirected to a page in the client area asking them to pay to upgrade to a High priority ticket. If they choose not to pay, the ticket stays at Medium.

Clients can also (optionally) upgrade any ticket at any time to High priority from within the Client Area.

Set Up

From the PowerTools dashboard, click on the Paid Priority Support tile:

Ensure the Tool is switched on and click Save:

Options

Upgrade Prompt: The message displayed to the client when asked to upgrade the ticket.
Upgrade Cost: The cost in your default currency to charge for the upgrade.
Invoice Description: The line item for the upgrade invoice.  The ticket number will replace the placeholder %tid%
Upgrade Sidebar: Option to display an upgrade message in the primary sidebar in the client area to give the option for the client to upgrade any ticket to High Priority
Sidebar Prompt: The message to be displayed in the sidebar for the upgrade.
Ticket Content: When a ticket is upgraded, this is the content of the new response that is added to the ticket. 

Workflow

When a user creates a new ticket, if they select the option of High Priority, the ticket will automatically be downgraded to Medium.

The client will then be redirected to the Upgrade screen. If they select Low or Medium instead, then no redirect occurs and the ticket is created as normal.

The client can click Cancel if they choose not to pay or click on Upgrade which will then generate an invoice:

Once the invoice is paid, the ticket priority is changed to High and an update to the ticket is added:

Optional Upgrade

You can (optionallly) display a prompt in the sidebar when a client views a non-High Priority ticket. The Upgrade link takes them to the same upgrade screen as above.
