Time and Materials vs Fixed Price vs Scope Based Model

Fixed-price contracts tend to work best when costs are well-known in advance. On the other hand, Time-and-Materials gives full freedom to change product requirements on the go. The buyer doesn’t have to bother about defining rock-solid application documentation before their contract commences. It is convenient to sustain long-lasting projects, rapidly shift priorities, react to market challenges or opportunities, and so on. Therefore, the buyer is at a larger risk compared to the fixed price model. By the time the project is finished, the final bill can be literally anything.

What is a Fixed Price Model

Time-consuming planning — it takes long brainstorm sessions and evaluation calls to analyze all possible issues and predict correct outcomes. The more complex is the project, the more difficult it is to get started since new details always come up. The quick feedback can promptly inform you on further iterations that are needed. With such a cycle, you end up designing what you actually need.

The Advantages of Fixed Price Contracts

With this model, the customer plays a greater role in the development of the software solution and carries all risks related to the scope of work. The level of responsibility that the client carries for the whole development process with time & materials is much higher than with fixed-price or milestone projects. The customer gets set up with a team and is billed for the actual time spent on development.

Another difference between time and materials vs fixed price models is in the degree of customer involvement in the development process. In this model, a client and development team define milestones iteratively, i.e. the next one is discussed and planned after the previous one is completed. A client approves the deliverables at the end of each milestone and makes the relevant payment only after that. An outsourcing company calculates the amount of money to be charged based on the number of hours developers spent to achieve a milestone goal. Unlike with fixed-price contracts, new ideas in the T&M model may be easily incorporated at any time.

Important decisions have to be made throughout the development process, so a client must be involved all the time. I have already made a point that it makes little sense to prepare upfront full-detail requirements. Instead, as requirements are being produced and refined, they are also prioritised to make sure that more important functionality will be implemented before the more trivial ones. With this in mind, here’s why I believe clients would be much better off with T&M contracts versus fixed price.

The development team can also start working straight away, even if they don’t know all of the project details yet. Before choosing a fixed-time contract you need to schedule a meeting with the development team first, during which you will discuss all of the project specifications. These must be crystal clear to both you and the developer, so you need to plan down to the finest details. Otherwise, it might be that the final product isn’t exactly what you hoped it would. Fewer interactions between a customer and a vendor during a software development process may result in misunderstandings.

Key Fixed Price features are:

While this may be normal, it also can disrupt the agreed-upon schedule and budget and reduce the seller’s planned profit. Since your employees get paid for the actual result rather than for hours spent in the office, they will do their best to implement a quality product within the time period allowed. The detailed estimate shows a precise sum that is to be paid for the project implementation. Nevertheless, it still contains both minimum and maximum columns. The first one is composed by the developers and shows a number of hours needed for coding of each option.

In order to avoid penalties, a development company that works by Fixed Price is interested to deliver the project on time, sometimes even at the expense of quality. As for the cost estimates — developers, working on a Fixed Price base always put additional costs to the budget to ensure themselves from contingencies. Once all the details are agreed and both the parties sign a fixed price contract, software development process begins. Since many clients are not IT specialists, their understanding of the development process may be rudimentary or misconceived. The education phase enlightens them regarding the subtleties of fixed price contract project management. At this point, the sales managers act as consultants who shed light on the hidden pitfalls that may be encountered.

  • If a feature requires more time, the execution will be more expensive.
  • Thanks to the usage of the Agile method, it is possible to make instant changes within a project when they are needed.
  • In the fixed price model, the development team provides the product owner with the full time and resource estimation, as well as a full report on risks with possible buffer costs.
  • The allocation process, of overhead against products, is always arbitrary.
  • For bigger changes this is justifiable, but for small adjustments the overhead on the formal flow makes the work much more expensive.

A Fixed-Price model allows you to leave all of the work to the developers until the product is ready. A fixed price is a non-negotiable sum charged for a product, service or piece of work. Projects with a set of predetermined features that definitely won’t need to be changed in the fixed price vs time and material future. A fixed price, which means there won’t be any additional expenses out of nowhere. Constant communication with developers and full involvement in the workflow . Even though it may seem like a plus for some, most customers find daily reports, planning and meeting tiring.

Part of that budget will also be spent on change management overhead, as opposed to delivering additional business value through software. When a project is really small and with easily-determinable requirements, both contracts will do the work, but a fixed price may be a better fit here. Also, to limit the risk of changing requirements, the software house usually charges a premium for the uncertainty . In time and material, there’s no reason for this overhead. In fact, with a time and material contract, you are more flexible in terms of budget management.

What is a Fixed Price Model

Firm fixed-price contracts tend to be best suited for straightforward projects in which costs are well known in advance. One example would be the delivery of 100 gaskets in two weeks. There are usually other sections such liability, terms for terminations of contracts, delivery, payment terms etc. One of the Fixed Price project risks is a chance to be overcharged if you give an unclear formulation of requirements. Usually, the team gets in touch with the client once a day during the daily meetings.

On the other hand, the lack of communication can drag the project on. With proper planning, however, time and materials is the most viable model for long-term projects. Moreover, when the project is indefinite and it is impossible to accurately estimate the time and materials required, both parties will proceed to consider using the T&M contract. In this case, where things are still ambiguous, a fixed-price contract is not recommended as actual costs can significantly exceed the agreed-upon contract, and also the client’s budget. A fixed price model is usually chosen by public and not-for-profit organizations for small and medium size projects. Under the T&M pricing model, this delta if available can be spent to implement some extra nice-to-have features and tasty delights.

Time and Materials vs Fixed Price Contracts – What to Keep in Mind

These discussions are also dynamic and happen throughout the project — hence, there is less pressure at the initial stages. You spend less time and resources on getting the paperwork done right before starting. There is less chance of miscommunication about a feature. Since you get frequent updates, you can fix mistakes quickly. This saves you precious time that you can use to take care of your core business. Things like communication challenges, changes in the software environment, new studies, legal requirements and market changes can give you a headache.

On the other hand, if the project can be completed faster, the product owner saves the budget. Adaptability to changing workloads — a development team and business owner can agree to spend more or fewer hours on a particular feature, instead of blindly following the anticipated schedule. This allows prioritizing quality over quantity and delivering the best results, instead of short-term patches. No micromanagement — fixed price allows a business owner to bypass constant monitoring and fully outsource the project. When you have a precise estimate with all outlined details and end outcomes, you don’t have to constantly check up on the cost changes.

Why we work on the Time and Materials basis

If a vendor is falling behind a delivery schedule, the team can be ramped up, or development speed increased in other ways, if necessary, to meet the delivery deadlines. 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. The most prominent alternative to fixed price is the Time & Material, or simply T&M, type of contract. I will assume that the differences between the two are obvious and won’t bore you with explanations on what they are.

These details enable the project owner to know exactly what they’re paying for and where the project stands. Time and material pricing is a method of billing the project owner based on hourly labor costs and the price of materials used. Usually, hourly rates, costs for using equipment, markups for any subcontractors, and materials are agreed upon ahead of time.

Fixed-price contracts presuppose a solid understanding of requirements, the case when the project scope is documented in a specification, UI/UX design estimation documents, and acceptance criteria. Time and materials doesn’t provide the same level of clarity. At the very beginning, both parties have a vision on their next step and an idea of the result — but the exact strategy and cost can fluctuate. Time and materials model is based on time efficiency — each task is estimated individually and the entire project is analyzed on an hourly basis as well. However, it requires smooth constant communication, otherwise, the tasks can get dragged on.

Once the project is underway, monitor the work against the schedule and budget. Include deliverables that are well known and perhaps repeated; an example would be the delivery of ten reams of computer paper each week. Because FP-EPAs allow for adjustments to the contract price, they’re often suited for contracts that extend for multiple years. To minimize the risk of misunderstanding, all parties should explicitly identify the criteria under which an adjustment is allowed.

A fixed-cost approach can be either the best or worst choice for the freelancer. While the price is often a deciding factor to choose the vendor, most customers have budgetary concerns.

When a business owner and development team try to estimate the project’s progress early on, crucial details get overlooked — and it might have disastrous consequences for the end product. Let’s take a look at the model’s main cons and their implications. Time and materials pricing might be the way to go for projects where the scope of work isn’t precise. By agreeing upfront on hourly rates, the owner is paying for the work completed and materials used.
