The challenge is measurement. For sales people, it's easier to measure the individual sales, hence you can have commission based on individual performance. For developers it is much harder to measure individual performance. We have implemented commission for developers based on overall sales number. Based on pre-announced targets, developers can get 1x, 2x, 3x salary as a bonus/commission at the end of the year. No caps.
