License Transfer

Greetings

I would like to know how can I buy and transfer a license. I have a client and I'm using metronic to build their project. I have my own to use it, but I need to buy one more, to transfer to them so they can use it at will, so if they register anywhere with metronic you guys know the client and no one else can use it..

I include the cost of metronic license in the development..

BTW excelent work you are doing with this templates..

Thanks..
