Cost Plus is a type of contract where the contractor gets paid for all their actual costs (like materials and labor), plus an additional agreed-upon amount for profit. This is different from fixed-price contracts because the final cost isn't set at the beginning. It's often used in construction, government work, or projects where the exact costs are hard to predict. Other names for this include "cost-plus-fee," "cost reimbursement," or "time and materials plus profit." This approach helps protect contractors when project costs are uncertain while giving clients transparency into all expenses.
