Cost-plus

A cost-plus contract is a type of contract where a contractor is reimbursed for all its allowed expenses (costs) up to a certain point, plus an additional payment (profit). This profit is often a percentage of the costs, a fixed fee, or some other agreed-upon formula. These contracts are frequently utilized when the scope of work, materials required, or project timeline is difficult to accurately define at the outset. They transfer some of the risk from the contractor to the project owner. The primary aim is to cover the contractor's expenses, ensuring fair compensation while allowing for flexibility in project execution. It's essential to carefully define 'allowable costs' in the contract to avoid disputes.
