The use of a cost-plus contract can have drawbacks. Since a contractor must justify the reasons why the expenses are related to a project, this may require additional efforts to manage and track all related expenses. For disorganized contractors, a cost-plus contract could really create some problems. A cost-plus contract, also known as a cost-plus contract, is a contract by which a contractor is paid for all eligible expenses, plus an additional payment to enable a gain.  Cost reimbursement contracts are contrary to fixed-price contracts, in which a negotiated amount is paid to the contractor regardless of the costs incurred. Cost-plus is often used for research and development because the risk can be controlled by the contract agent. Governments generally prefer cost-plus contracts because they can choose the most qualified contractors instead of the lowest bidder. costs plus percentage of marginal overhead and profit costs: on this basis, the contractor is not encouraged to complete the work quickly or at the lowest cost; The more time the contractor spends and takes, the greater the benefits. In the case of a cost-plus contract, the contractor receives all the expenses of a project, plus an agreed profit, generally defined as a percentage of the total cost of the contract, or a fixed fee.
Since the allocation of costs plus is primarily for research and development, it is expected that the percentage of cost-plus contracts in a contract will be correlated to the percentage of research in a given program. However, several programs, such as the Lockheed Martin F-35 Lightning II, the UGM-133 Trident II, the CVN-68 and the CVN-21, are moving away from this model by continuing to use cost-plus contracting on a large scale, although the programs are gradually moving beyond the state of research and development.  Cost-plus contracts can be divided into four categories. They allow reimbursement of costs and an additional benefit: cost-plus contracts are also used in research and development, where a larger company can outsource research and development activities to a small company, such as a pharmaceutical company. B large size, which goes to the laboratory of a small biotechnology company. The U.S. government also uses cost-plus contracts with military defense companies that develop new technologies for national defense. The total cost was $20 million, including direct labour costs, equipment costs and project overheads. The necessary documents such as invoices, working hours for a project, labour costs have been made available to the contractor. As a result, the total income of the contractors will be equal to $20 million – 20% – $4 million – $0.5 million – $4.5 million.
Finally, a final drawback, this time for owners: cost-plus contracts can create a kind of conflict of interest for contractors, which can result in higher prices for homeowners. Think about it: cost-plus. The higher the cost of the project, the more “More” the contractor can charge. As a result, there is little incentive to keep costs low unless there is a spending cap. A cost-plus contract is an agreement to reimburse the costs incurred as well as a given profit, usually indicated as a percentage of the total contract price. This type of contract is mainly used in the construction sector, where the buyer assumes some of the risk, but also offers a degree of flexibility for the contractor. In this case, the contracting party expects the contractor to meet its commitments and commits to paying an additional profit to enable the contractor to make additional profits once completed. Cost-plus contracts are important in the construction industry, where the contractor is reimbursed for the number of expenses he made for the contract and a fixed percentage of contract costs as a contractual benefit.
