Buy resource manager under different licence



I'm looking for some advice on what I should do in this situation. The forum I look after(system admin/keep online) are looking to get the resource manager add-on to which I will be customizing. But the current licence holder is flying back from PAX east and we will be unable to get hold of him until after the sale.

I have a personal xenforo licence which is current, so is it possible to buy the resource manager add-on under my account and use it on the forums that I manage(I do not have access to the licence account)?

Thank Rob.
