What Is a Cost-Plus Contract?

When embarking on a complex project or service engagement, selecting the right type of contract significantly contributes to the project's overall success. One contract type offering flexibility on costs when the total is unknown is the cost-plus contract. It is commonly used in government projects, construction, and even consulting services. In this article, we’ll explore what a cost-plus contract is, how it works, its advantages and drawbacks, and when it’s typically used.

Definition of a Cost-Plus Contract

A cost-plus contract, also known as a cost-reimbursement contract, is an agreement where the client pays the service provider for their actual expenses incurred in completing the project, along with an additional fee to cover overhead and profit. The service provider is reimbursed for direct expenses, including labor, materials, and other associated costs, and receives an agreed-upon percentage or a fixed fee for their services.

Cost-plus contracts are often used for projects where the scope of work is uncertain or subject to change. They can also be used for projects that are complex or require specialized expertise. 

Key Features of a Cost-Plus Contract

A cost-plus contract has several distinct features that make it suitable for projects with uncertain or evolving scopes. They are defined by their flexibility, cost reimbursement structure, contractor fee provisions, and emphasis on transparency and collaboration. Here are the key features of a cost-plus contract in more detail:

1. Reimbursement of Costs:

The number one hallmark of a cost-plus contract is where the client reimburses the service provider for all allowable costs incurred during the project.

2. Fee Structure:

A cost-plus contract typically comes with a term outlining the fee structure. The service provider receives a fee in addition to the reimbursed costs. The fee can be fixed, a percentage of costs, or based on performance.

3. Flexibility:

The cost-plus contracts are often used when the project scope is uncertain or subject to change. This type of agreement grants the contracting parties flexibility on the project scope and price as project requirements or market conditions evolve. 

4. Shared Risk:

In a cost-plus agreement, the client and service provider share the risk of cost overruns or unforeseen challenges to the project. 

5. Potential for Cost Overruns:

Without proper cost control, cost-plus contracts can lead to higher than expected costs. See the next section on fee structures for insights on how some organizations may choose to mitigate the issue.

Typical Terms of a Cost-Plus Contract

Cost-plus contracts, while offering flexibility, typically include specific terms to outline the contractual relationship between the parties. It contains several terms that outline the responsibilities, payments, and expectations of the service provider and the client. These terms define how costs will be managed, how the service provider will be compensated, and how the project will be executed. Here are some common terms:

1. Scope of Work

Although cost-plus contracts are often used when the exact scope of work is not fully defined, a general description of the project and desired outcomes must be included. This section details the overall objectives, deliverables, and any specific milestones the service provider must meet. The scope may also include any known constraints, expected quality standards, and the roles of each party involved.

2. Cost Definitions

Direct Costs: These are costs that are directly attributable to the project. Examples include labor, materials, and equipment used specifically for the project.

Indirect Costs (Overhead): These are general operating costs that are not directly tied to a specific part of the project but are necessary to the service provider’s operations, such as administrative expenses, office space, or utilities.

Other Allowable Costs: The contract may specify other costs that can be reimbursed, such as travel expenses, subservice provider fees, or equipment rentals.

3. Reimbursement Terms

Cost Reimbursement: The client agrees to reimburse the service provider for actual costs incurred during the project, based on documented expenses. The service provider is required to submit detailed invoices and receipts for these costs.

Audit Rights: Many cost-plus contracts include provisions for the client to audit the service provider’s records and verify the costs. This ensures transparency and safeguards the client against inflated expenses or mismanagement.

4. Fee Structure

Fixed Fee: The service provider receives a predetermined fee, which remains constant regardless of the final project costs. This provides some financial certainty for both parties.

Percentage Fee: In some cases, the service provider’s fee is a percentage of the total project costs. This can incentivize service providers to increase the overall cost, so these contracts are less common or come with oversight mechanisms.

Incentive Fee: The service provider may be eligible for an additional incentive fee based on certain performance criteria, such as completing the project ahead of schedule or under budget. To mitigate the potential for cost overruns, some organizations use incentive fees for the service provider to perform efficiently. For example, a Cost Plus Incentive Fee (CPIF) structure offers a bonus for meeting or exceeding project goals, such as completing the work under budget or ahead of schedule.

Award Fee: In this variation, the service provider can earn an award fee based on subjective evaluation criteria related to performance, quality, or innovation.

5. Payment Terms

Progress Payments: Payments are typically made as the project progresses, based on milestones or periodic (monthly, quarterly) invoices submitted by the service provider. The service provider is reimbursed for incurred costs along with the agreed-upon fee or profit.

Retention Clause: In some contracts, the client may withhold a percentage of each payment (e.g., 10%) until the project is fully completed and accepted. This ensures that the service provider remains incentivized to finish the project satisfactorily.

6. Project Timeline and Completion

This section outlines an estimated timeline for the project’s completion. This includes major deadlines, delivery of critical milestones, and any contingencies for delays. Since the project scope may change over time, the contract should include provisions for adjusting the timeline if the scope of work or costs increase unexpectedly.

7. Change Management

This section specifies how change orders (modifications to the original scope) will be handled. This includes how changes are requested, evaluated, and authorized. Change orders often lead to cost adjustments and timelines, so a well-defined process ensures that both parties agree to changes in advance.

8. Service Provider Responsibilities

The service provider’s duties include overseeing the project’s execution, hiring subservice providers if necessary, procuring materials, and ensuring the work complies with industry standards and regulations.

Quality Control: The contract may include requirements for quality assurance, specifying performance standards or benchmarks that the service provider must meet.

Risk Management: The service provider may be required to implement risk management practices to mitigate unforeseen challenges, such as delays, cost overruns, or safety issues.

9. Client Responsibilities

Timely Payments: The client is responsible for making payments to the service provider according to the terms agreed upon in the contract. Payment delays could result in project delays.

Approvals and Decisions: The client may need to provide timely decisions, approvals, or clarifications regarding changes to the project. A delay in providing necessary input may impact the project timeline or costs.

10. Termination Clause

The section outlines conditions under which either party can terminate the agreement, including termination for convenience (by the client without specific cause) or termination for default (due to failure to meet contractual obligations by either party).

This section will also specify how outstanding costs will be handled in the event of early termination, including compensation for work already performed and materials already purchased.

11. Dispute Resolution

This section details how disputes between the service provider and the client will be resolved, such as through mediation, arbitration, or litigation. Some contracts may specify that disputes must be settled out of court.

12. Liability and Insurance

The section typically outlines the service provider’s insurance requirements, such as liability coverage for accidents or damages during the project. This ensures that the service provider is adequately insured against risks.

Limitation of Liability: It may also define the limits of liability for both parties, specifying what damages can or cannot be claimed in case of project failures, accidents, or delays.

13. Intellectual Property

This section clarifies the ownership rights for any intellectual property created during the project and may grant licenses for using intellectual property developed under the contract.

14. Force Majeure

The section defines events beyond either party's control, such as natural disasters or acts of war, that may excuse contractual non-performance.

Remember that these are general terms; specific cost-plus contracts may include additional provisions specific to the unique project requirements and the parties involved. It is advisable to consult with your in-house legal team when drafting such an agreement.

Types of Cost-Plus Contracts

There are several variations of cost-plus contracts. As previously mentioned, the type depends on how the service provider’s fee is determined. The four most common types are explained below. Consult with your in-house legal team about the contract that best fits your project. 

1. Cost-Plus Fixed Fee (CPFF):

In this arrangement, the service provider is reimbursed for all project costs plus a fixed fee, regardless of the project’s final cost. This fee doesn’t change even if the project’s actual costs go up or down.

2. Cost-Plus Percentage of Cost (CPPC):

Under this model, the service provider's fee is calculated as a percentage of the total project costs. This method can incentivize the service provider to increase costs, so it’s used less frequently.

3. Cost-Plus Incentive Fee (CPIF):

In this variation, the service provider is reimbursed for costs, but the final fee is adjusted based on whether the service provider meets certain performance goals (e.g., completing the project under budget or on schedule).

4. Cost-Plus Award Fee (CPAF):

This structure adds an award fee that is subjectively determined based on the service provider's performance, cost reimbursement, and a fixed fee.

Where Is a Cost-Plus Contract Used?

Cost-plus contracts are most commonly used in projects where estimating costs upfront is challenging. Here are some real-world scenarios where a cost-plus contract might be the best suited:

1. Large-Scale Construction Projects:

A cost-plus contract allows for flexibility for extensive, multi-phase construction projects where the full scope of work may not be known in advance.

2. Government and Public Sector Projects:

Cost-plus contracts are often used in public works projects, particularly when the scope is uncertain or when the project demands high-quality results that can’t be compromised by cost-saving measures.

Defense Contracts: Due to the complexity and classified nature of many defense projects, cost-plus contracts are often used to manage risks and ensure transparency in pricing. 

Research and Development: Government-funded research projects can have unpredictable outcomes. A cost-plus contract allows for adjustments in funding as the project progresses.

3. Research and Development (R&D):

R&D projects frequently involve unforeseen challenges, making it difficult to define costs upfront. In medical research, clinical trials and drug development can involve unforeseen costs and delays. A cost-plus contract provides flexibility in funding.

4. Technology & IT Services:

Software Development: Developing complex software systems can involve iterative processes and evolving requirements. A cost-plus contract ensures that the client isn't penalized for changes made during development.

IT Consulting: When the exact scope of IT consulting services is unclear, a cost-plus contract provides flexibility to address unforeseen issues or additional requirements.

Advantages of Using a Cost-Plus Contract

Cost-plus contracts come with several benefits that make them an attractive option in certain scenarios:

Flexibility:

Cost-plus contracts can be more flexible than fixed-price contracts, as they allow for changes in the scope of work or when the cost is difficult to predict in advance.

Risk Mitigation for the Service Provider:

In a cost-plus contract, the service provider takes on less financial risk compared to a fixed-price contract. Since the client covers all costs, the service provider is less likely to face losses if the project runs over budget.

Client Control Over Quality:

Because the service provider isn’t focused on cutting costs to protect their margin, the client often has more influence over the quality of materials and craftsmanship. The service provider is incentivized to deliver the best results rather than the cheapest.

Collaboration:

The nature of cost-plus contracts fosters a collaborative environment between the client and service provider, as both parties can collaborate to adjust project needs and costs throughout the project's progression.

Drawbacks of Using a Cost-Plus Contract

There are also several disadvantages to using cost-plus contracts, most of them revolve around cost, including:

Increased Cost:

Cost-plus contracts can be more expensive than fixed-price contracts, as the service provider is reimbursed for all of their allowable costs.

Reduced Incentive for Cost Control:

Because the service provider is reimbursed for all their allowable costs, they are less incentivized to control costs.

Potential for Cost Overruns:

Cost-plus contracts can be subject to cost overruns, as the service provider may have an incentive to inflate their costs.

Potential for Disputes:

Given the complex nature of cost-plus contracts, disputes can arise over what constitutes a reimbursable expense, especially when dealing with indirect costs or overhead.

The takeaway is that cost-plus contracts can be well-suited for projects where the scope of work is uncertain or subject to change, but they can also be more expensive and subject to cost overruns. It is essential to carefully consider the advantages and disadvantages of this type of agreement before deciding whether to use it.
