The problem is always the same with commissions, anywhere: kickbacks ("retro-commission" in french). It does definitely happen in the software industry. You find someone responsible for acquisitions and you tell them: "Look man, if you buy 200 licences of this I'll get a commission and I'll give you under the table a kickback of 25% of my commission". You're a fool if you think this doesn't happen and there are some very famous names in this industry where sales people are known to behave this way. The good move is to completely suppress them but the problem is that your competitors may be employing sales people using shaddy practices so you'll, sadly, all too often not be competing on merits.
