Difference Between Fixed Price And Time & Material Contracts

As the name suggests, this model is a fixed-price contract where the software development team must deliver the project within a predefined sum which is agreed by both the parties. The planning stage is shorter compared to a fixed price project as a software specification doesn’t need to be as detailed, so you can start the active work on software development earlier. Fixed Price model assumes that the total budget on the project is approved before development starts and remains unchanged. Also, before development starts the exact deadline must be approved. The risks for late execution of works will be borne by the contractor. On the one hand, this model may seem convenient for you, as a customer, as you know how much time and money the project development requires before the work starts.

However, the same can be achieved with a T&M contract when working towards a milestone in a release or delivery plan. After all, a T&M contract often only defines the daily rate and total budget with sufficient flexibility in budget burn rate while working towards delivery goals. DCI’s Time and Materials pricing model is inherently adaptive with combined judgment on project changes which strengthens the development effort.

Fixed-Price Contract T&M Contract Project Requirements Determined at the start of a project. Labor rates and cost of materials are determined at the start of the project, but the full cost is determined at the end. Larger projects whose requirements are hard to pin down at the outset of a project. Based on the costs of time and materials for the duration of the project; may include a not-to-exceed-clause to keep costs in check.

At Orangesoft, we can help you identify your pain points and write a detailed project specification, and then, we develop cost and time estimates based on those specifications. A fixed-price incentive contract specifies a target cost, a target profit, a price ceiling , and a profit adjustment formula. The price ceiling is the maximum that may be paid to the contractor, except for any adjustment under other contract clauses. When the contractor completes performance, the parties negotiate the final cost, and the final price is established by applying the formula.


Some time back we needed some new electrical outlets installed in our house. It was a straightforward well-defined job and we got fixed-price quotes from two electricians and picked the one who gave us the lower price and could complete the job within a week. The electrician delivered as promised and left behind a satisfied customer.

We called a couple of general contractors, one of whom gave us a rough estimate but would only do the project on a time and materials (T&M) basis due to the inherent uncertainty in the scope.

In this type of pricing, a client knows exactly what piece of functionality is being developed and what results to expect at the end of each milestone.

Which Contract Type Should You Choose?

Expressly provides that the award amount and the award-fee determination methodology are unilateral decisions made solely at the discretion of the Government. Because performance incentives present complex problems in contract administration, the contracting officer should negotiate them in full coordination with Government engineering and pricing specialists. Performance tests and/or assessments of work performance are generally essential in order to determine the degree of attainment of performance targets. Therefore, the contract must be as specific as possible in establishing test criteria and performance standards . A cost-sharing contract may be used when the contractor agrees to absorb a portion of the costs, in the expectation of substantial compensating benefits. A cost contract is a cost-reimbursement contract in which the contractor receives no fee.

T&M-based development goes in hand with continuous testing to verify the implementation of requested changes and new features, so software gets honed to perfection throughout multiple project iterations. Together with a vendor, you agree on a project roadmap and set related milestones, but the scope of work remains dynamic and can be changed as you see fit. You can make informed decisions on the next steps of development, drawing on the outcomes of the previous ones (end-user feedback) and the analysis of the latest market tendencies.

Basic agreements may be used with negotiated fixed-price or cost-reimbursement contracts. A definite-quantity contract provides for delivery of a definite quantity of specific supplies or services for a fixed period, with deliveries or performance to be scheduled at designated locations upon order. This approach also may apply to other acquisitions, if the use of both cost and technical performance incentives is desirable and administratively practical. Most incentive contracts include only cost incentives, which take the form of a profit or fee adjustment formula and are intended to motivate the contractor to effectively manage costs.

With NetSuite, you go live in a predictable timeframe — smart, stepped implementations begin with sales and span the entire customer lifecycle, so there’s continuity from sales to services to support. The service provider has completed similar projects for other customers. If you are wondering which of these cooperation models would be best for you then you’re in the right place. In this article, we will take a look at the three aforementioned contract types and how they work. A basic ordering agreement shall not state or imply any agreement by the Government to place future contracts or orders with the contractor or be used in any manner to restrict competition. Each basic agreement shall be reviewed annually before the anniversary of its effective date and revised as necessary to conform to the requirements of this regulation.

The hourly labor rates are agreed upon by a client and a contractor beforehand. As for the payment intervals, they are also flexible and negotiated in advance. But profitability depends on many factors — including the way a service provider contracts with its customers.


When it comes to payment plans for IT projects, there are two prevalent methods. How do they differ and is the correct choice always obvious? Discover the difference between Fixed Price and Time & Material. The only projects that can benefit from the Fixed Price model are ones that are small and relatively simple – in some cases, that could be a Minimum Viable Product. If you’re able to develop accurate requirements and know that the project isn’t going to require any changes in the near future, this model is for you. You might be worried that leaving the budget flexible will mean that the costs of your project will rise uncontrollably.

Project Management Contract Types

Business Why is it better to launch the basic product than to improve it endlessly. Fixed price contract is great for Minimum Viable Product development and other small projects, especially if the deadline matters. Time and material offers more flexibility with respect to development and gives more control over the project development. Complicated and long term projects with cross functional teams. Even after years of experience in software development, we can’t name all possible scenarios evolved with the dynamically changing technology environment and very specific nature of the software development. There are increased chances that the project will cost more than expected since changes are inevitable when building a software product.

Each agency head shall provide mechanisms for sharing proven incentive strategies for the acquisition of different types of products and services among contracting and program management officials. A ceiling price shall be negotiated for the contract at a level that reflects a reasonable sharing of risk by the contractor. The established ceiling price may be adjusted only if required by the operation of contract clauses providing for equitable adjustment or other revision of the contract price under stated circumstances. Discuss the Government resources necessary to properly plan for, award, and administer the contract type selected (e.g., resources needed and the additional risks to the Government if adequate resources are not provided). Selecting the contract type is generally a matter for negotiation and requires the exercise of sound judgment.

A letter contract is a written preliminary contractual instrument that authorizes the contractor to begin immediately manufacturing supplies or performing services. The contract shall specify separate fixed hourly rates that include wages, overhead, general and administrative expenses, and profit for each category of labor (see 16.601). If the contract is for nonpersonal services and related supplies and covers estimated requirements that exceed a specific Government activity’s internal capability to produce or perform, use the clause with its Alternate I. Except as provided for in paragraphs and of this section, the ordering period of a task-order contract for advisory and assistance services, including all options or modifications, normally may not exceed 5 years.

Each division, subsidiary, or affiliate of the contractor under a common control. Transferred between divisions, subsidiaries, or affiliates of the contractor under a common control. Involves a partial small business set-aside, use the clause with its Alternate IV.

In simpler words, the time and material contract is an hourly rate or a pay-as-you-go model. The payment frequency and the ways to pay for labor are subject of negotiation. Software development is more complex than that, as you can imagine; it can involve departments and teams or solo developers. It is important to keep pricing models simple, and these two are the most common and straightforward. The pricing structure of the fixed price business model is pretty much straight.

The customer and development team can spend a substantial amount of time planning out the product development roadmap in detail. This process can be a potential drawback when it comes to short deadlines as it can be time-consuming. As previously mentioned, if the project requirements change during the development process, the client would be additionally charged. Some say that Fixed Price contracts are good for the waterfall development methodology.
