Having a store item bought to you by someone else

As the title says, how can I get someone (a client, who has no unity3d installed) to pay for a store item and have it available on my account? Hints/ideas?

Invoice them, get the money and then buy it yourself.

Sometimes, as in my case, that person handles your finances and has all the security on their computer. My case is similar to MaDDox. I have the money and give it to my partner and he purchases the items for me. However, he is a business person and does not have Unity on his computer.

It would just make things 10x easier (and quicker!) if he could just buy it himself. Anyways, I’ll try to get him to paypal-transfer me the money.
