[Dragon Ball Z] Who is Frieza selling planets to and what are they offering in trade?

At first the idea of him just selling planets makes sense if he's eliminating the entire population, but to whom is he selling them? Also what is he getting in exchange? Currency doesn't seem like a likely candidate so what is he getting in exchange for a planet?

Maybe he's selling lordship to a planet. Say you wanna run a planet with lots of illegal activities, but you can't take over a planet yourself. So you go to Frieza, he gives you the space and takes a rather large portion of profits from illegal activities. Similar to mob loans.
