Fixed-Cost contracts can be paid once a job is complete or in separate installments through milestones. Clients and freelancers should discuss the use of milestones during the interview process, including the number of milestones depending on the length of the project and the budget for each milestone. 

Milestones can only be created by the client and cannot be altered by the freelancer.
