Incentivizing Sales People - Multiple Scenario Planning with Comparison Visuals

Structuring commission plans for sales people can be difficult to get right. There are plenty of ways to do it, so what is best? In my opinion, it is better to make the commission rate a function of gross profit generated (if this is possible to calculate for your situation) rather than revenue sold. If revenue sold is the only thing trackable, that is fine and the model will still work.
