A cost-plus contract is a type of contract where the buyer agrees to reimburse the seller for the actual costs of
the work plus a fee, which can be fixed, percentage, incentive, or award based. This type of contract has the
highest risk for the buyer because the buyer has no control over the cost or quantity of the work and the seller
has little incentive to control the costs or complete the work efficiently. The seller may inflate the costs or
prolong the work to increase the fee. The buyer may end up paying much more than the estimated budget or
the market value of the work. References = CompTIA Project+ PK0-005 Certification Study Guide, Chapter 9:
