One decision on sales force compensation relates to the proportion of fixed vs. variable (per performance) pay.
The fixed part of the compensation comes in the form of a salary (does not depend on the sales performance). The variable part can have multiple forms, with the most common one being the commission (where the sales person receives some % of the sales revenue generated).
What are some factors to consider when deciding how much of the sales agent's compensation should come in the form of a salary and how much should be in the form of commissions?
