Final answer:
A license can receive an extra bonus for completing a difficult sale from a service contract or a warranty.
Step-by-step explanation:
A license can receive an extra bonus for completing a difficult sale from the service contract or the warranty. In a service contract, the buyer pays an extra amount and the seller agrees to fix anything specified in the contract that goes wrong for a set time period. On the other hand, a warranty is a promise to fix or replace the good for a certain period of time.
