I am trying to print a script on the invoices.php, to do this I used: add_hook('ClientAreaPageViewInvoice', 1, function ($vars) { add_hook('ClientAreaFooterOutput', 1, function ($vars) { return '<script> console.log("It is a invoice" );</script>'; }); }); But I want to do different things if is Renewal or New Order Invoices. I couldn't find a variable with debug.

I want to offer an email hosting only, where the customer pays by email account. I configured the prices, but which Payment Type do I use? Free, One Time or Recurring? If I put it free to start it will generate the monthly charge?
