What is a key characteristic of a sales commission structure?

A sales commission structure is primarily characterized by providing compensation based on the performance of the salesperson, which is directly related to the sales they generate. This structure incentivizes salespeople to increase their efforts in selling, as the more they sell, the more commission they earn. This model aligns the interests of the salesperson with those of the company, encouraging productivity and a focus on results.

The other options represent different compensation methods that do not rely on the performance outcome tied to sales figures. For instance, a fixed fee for every sale completed locks in compensation regardless of the overall sales performance, while a salary paid regardless of performance does not have a direct correlation to sales achievements. Lastly, bonuses given at the end of the fiscal year may reward performance but are typically not part of the ongoing commission structure that is dynamic and directly proportional to sales activity.
