Wen Transfering a Domain, it must show on the Invoice/Order/Details that is a "Domain Transfer", it may cause confuse to the client (it make me confuse not showing anywehere its a domain transfer).
Possible fix, just add a new language variable (Transfer) to be added before the service name if its a transfer.
For exemple, if the service is called "Domain .com" in the cart, order details and invoice, will show "Transfer Domain .com - mytestdomain.com (16/04/2014 - 16/04/2015)"
To be better, Blesta Should separate complitly the "Services" and "Domains" because Domains dosent work the same way as services do.
