Fixed-Price vs Time & Material which to pick for your project?

Implementation of this new feature has to be negotiated independently. With fixed-price projects, the paperwork and approval of new features takes much longer and can potentially stall the whole development process. Getting started with T&M, fixed price, or dedicated teams can be pretty daunting at first, but not with this guide within your reach. It starts by understanding what is the difference between fixed price and T&M projects, or dedicated teams, and discerning whether any of them matches your business goals. Alternatively, you can talk to us, and our experts will suggest the best approach.

Customers should choose a pricing model based on the type of project they have. If they have a clear understanding of their project and a limited budget, then a fixed-price model should be used. Clients should avoid including lots of functionality in this case and instead focus only on core features. If the project is quite flexible and requirements change frequently, then the time & materials model should be applied. When the parties have a long-term and trusting relationship, they can work according to the milestone model.

At ScienceSoft, we also apply this model for PoCs and MVPs as it allows businesses to field-test software concepts or check a new vendor’s experience in action with minimized budget risks. If the estimate is too large, the contractor loses the project to a lower bidder. Adding to the difficulty, the contractor’s costs can change between the estimate and the completion of work.

The Disadvantages of T&M Contracts

Here are some construction project management templates to help you save time. Considering the foregoing t&m vs fixed price model comparison, it is essential to weigh all the strengths and weaknesses of each contract type and how they can fit in your project. Each type of functionality will cost a different amount as different amounts of time were spent to develop them. The customer has to pay the total amount approved for each milestone. This type of contract is applied when there’s no set scope of work and when a lot of flexibility is required. The client must be willing to get really involved in the project since their approval and vision is an important part of development.

  • To be safe, always hold at least one in-person meeting for in-depth guidance.
  • Suddenly it turns out that many things could be implemented differently, the requirements were not so clear or we have some new ideas from customers and users.
  • If you are looking for a software house that will be responsive to your goals and pains – you should leave us a message and tell us about your newest project.

Materials include the necessary supplies, along with the costs of transporting them to the job site, as well as incidental services, such as cleanup work. While there are many similarities between the two contract types, a cost-plus contract separates profit from all other expenses. An agreed-on fee is either a fixed amount or based on a percentage of the project’s total cost. Contractors who use a T&M contract mark up costs of materials and other expenses to earn their profits.

It is worth to remember, that this contract includes project management, communication with the development team and other work that is required to develop and implement the product. Time and materials contracts are best when the scope of the job or its duration cannot be determined before work begins, as is sometimes the case in construction projects. When renovating an old building, for example, removing walls may uncover rot or other damage not visible before the job started.

This contract usually works better for longer-term projects that span several years. So that’s the main difference between those two models – fixed price and time & material approach. I recommend the fixed price contract for small- and mid-sized fully outsourced projects that don’t exceed 1-3 months of duration.

Time and Materials may not be ideal if the clients do not want to be a part of the team. It necessitates their presence and, in many cases, active involvement. Payments to the service provider are mainly based on a percentage of work performed. Such workflow requires little involvement since expectations are transparent and predictable. The product is well-tested and brought to near-perfection thanks to multiple iterations, resulting in high-quality software.

What is a fixed price model?

After the meeting, they start planning the second sprint with an eye on the milestones and the backlog. This way the vendor enriches the original specification with the new features at every sprint, which makes our product more flexible and satisfies the market needs. Minimum Viable Product is an application that can solve the specific business goal, although it may not work smoothly or have the pretty user interface. For example, we are often asked to develop MVPs to prove a particular idea or hypothesis.

Other options are periodic billing — perhaps weekly or monthly — or a lump sum at completion of the project. A time and materials contract is similar to a cost-plus contract in many ways, but not in the way it handles profit. Profit comes from the markup of costs in a T&M contract, whereas profit is a separate fee in a cost-plus contract. A T&M contract may also include a “not-to-exceed” clause, which sets a ceiling for the maximum number of labor hours should the project grow.

To possible received financial incentives fees for superior work. As the name suggests, a fixed-price contract is an agreement in which the cost is unaffected by the usage of resources or the amount of time spent on the project. It’s a straightforward setup that reduces paperwork and negotiating time. Therefore, the fixed-price contract is the inverse of the T&M contract.

The transparency of work in the Time & Materials model simplifies budgeting for individual stages. With T&M, savings of up to 10-30% of the budget are possible. The client manages the project budget using the Time & Materials approach. Furthermore, this paradigm causes additional control throughout the project. Depending on the internal goals, the client can adjust the number and makeup of the team, the work plan, the format, and the frequency of reporting. With such an approach, you can better track the development process, contact the developers more often.

Disadvantages of the fixed-price contract

However, almost in every project, there are changes that either inflate the initial scope of work or drastically change the product that is being developed. In this case, the development team has to spend extra effort and hence it costs extra; however, the client continues to rely on the initially agreed amount. Actually, it just seems that way and it does not really benefit the investor. It’s not necessarily a con of a time and material agreement, but rather a thing to watch out for.

The average outcome to expect in either model comes as a package with the service provider. It’s also worth noting that all the other risks involved in the development are typically in your hands, given that both models give you greater flexibility and control. For some projects, a fixed-price contract, where the total cost is determined from the start, may make more sense; for others, an open-ended T&M contract may be better suited.

Time and Materials Contract vs. Guaranteed Maximum Price (GMP) Contract

And since profit is separated from costs, the contractor makes money regardless of unexpected expenses along the way. To guard against expenses getting out of hand, a project owner may require the cost-plus contract to include a cap on the final price. If, for example, a contractor estimates a project will cost approximately $100,000, the project owner may allot a maximum of another $10,000. If the contract also stipulates a fixed $20,000 profit, the most money that can change hands is $130,000. The profit part of a cost-plus contract — the “plus” — can be calculated a few different ways. In a cost-plus fixed-fee contract, the contractor is paid a set, negotiated fee regardless of the final cost of the project.

Materials costs could rise, laborers could drop out of the workforce, new regulations could be imposed. That’s why some contractors propose a time and materials contract. A fixed-price contract, also referred to as a lump-sum contract, determines the exact price of a project before it begins. A T&M contract may be used when it’s difficult to accurately determine that final figure because the exact scope or duration of the project is unclear. Rather than establishing a fixed price for the entire project, a contractor sets fixed prices for labor rates and job materials, which are marked up to include a profit for the contractor. A very important part of construction project management is time and cost estimates.

You want to build a complex software solution where the development process can take months or even years. Importantly, both parties agree on what materials will be used and on the hourly rate. So, even if the project takes much longer or much less time than anticipated, both parties can rest assured that they will be reimbursed and receive the work carried out or expected. As described above, long planning is required to estimate the most accurate price for the software that will be developed. But that can be a potential drawback when it comes to short deadlines. And still, we might not avoid some communication misunderstandings while the project is ongoing.
