Where does the robux go? Keep it simple and clear!
Imagine GroupA create a game called GameA and sell a product called ProductA for 10 robux where does the 7 robux go?
A. The group owner
B. Anyone who have access to edit game
When a group game sells a dev product or a gamepass, the robux revenue becomes group funds. Users with a role that has permission to give funds (most likely only the owner) is able to give it to themselves or other users in that group.
