Why Sla Based Contracts Are Better Than Time & Material Model

The main advantage of T&M model is flexibility and opportunity to adjust requirements to business trends, replace features and shift focuses. Creating detailed documentation is not something you can do overnight. The software company that signed a fixed price contract must thoroughly think about every possible aspect of the project. If a time and material contract is beginning to look more appealing to you then this is good news. You’re on the first step to making your life a whole lot easier next time you need to have a piece of software created.

What is a Time And Material Model

Sprints are short, easily manageable, and more effective when it comes to monitoring the whole development process. Also, in Agile, testers and developers collaborate very closely as error fixing happens immediately after bugs are detected. Often, the major part of communication happens on the signing contract stages when partners negotiate all the ins and out of a project. Once it’s done, you should define tasks and assignees within each activity, due dates and milestones.

Each sprint begins with the analysis and creating the so-called sprint backlog, which is a list of features or scenarios that need to be completed during the sprint. Do you think about building a reliable product with the smallest risk and reasonable budget at the same time? In this article you will find the answer on how to achieve this goal. On the one hand, it allows you to market a relevant product that will meet users’ demands. On the other hand, it may result in exceeding the time frame and overfunding. Unlike the Waterfall method, where the client reviews the product only at the end, in the Agile methodology, it is okay to fix bugs or change the initial concept halfway to the final result.

To make it clear, the difference between the client and the software house can be illustrated when compared to a soccer game. When you sign the contract with fixed price you both play on opposite teams — the agency tries to do just as much as needed to make a product with certain features. You, on the other hand, require the best possible quality within agreed budget. Yours and the agency’s priorities are completely different, so it’s not that easy to build a valuable product . 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.

The T&m Contract In Software Development

When everything is planned and nicely documented, management is much easier. Thus, a product owner doesn’t have to actively participate in the development process. All the decisions have been made, so the rest in the team’s hands. 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.

  • Let us first take a look at what a typical fixed price project is and what preparations you’d need to make before you can start.
  • This is a good model for all projects where the specifications of the project / product are clear and well predictable with all aspects of estimati…
  • We believe that potential non-payment for two weeks of work is less risky than incorrect evaluation of an innovative product.
  • Under TM contract, the customer will pay only for real project work.
  • What this means is that the company will allow you to make a number of changes and be more liberal with the adjustments in cost to the plan that they make rather than handing out massive fees.

We’d rather not set a rigid total price because valuing new digital products is very difficult due to their innovatory nature, specific requirements and unpredictability. Thus, the valuation process includes estimations which are only predictions for feature creation time. In fixed price model the contract budget is always just an estimation. This means that agencies add extra budget to mitigate possible risks and make their project affordable. This financial cushion could range from 20% to 100% of the real value.

Well-planned timeframes, work schedules, and costs are set out in terms of a contract and decrease the probability of conflicts between the parties. You are not required to actively participate in the development process, so you can focus on important aspects of your business. Besides, in the beginning, you would have set stringent performance goals that are measurable every step of the way as the development process progresses.

Time And Material Vs Fixed Price: What To Choose For Your Project?

How to know that an IT contractor isn’t going to build a product that will meet your business needs. The client is actually paying not for the amount of work but for the man-hours it takes to deliver a product and push it to the market. So there’s a risk for the client to get stuck with a dishonest vendor who will inflate the time it takes to deliver the project into infinity. Either you have total control over the timeline, or you make adjustments in a flexible development process. Only in the latter case, you need to know that the final release date is hard to plan from the start.

What is a Time And Material Model

The client has the freedom to change the specifications of the project, or to add new components, as it is understood that such changes will incur more time on the project, and hence a higher invoice. The disadvantages come if you bill too many hours and exceed the client’s budget. This can cause friction if the budget runs out before the contract is completed.

The main task is to obtain feedback for the formation of hypotheses for further development. It presupposes billing clients for actual work scope based on hourly rates of labor. Customers are charged for the amount of hours spent on a specific project, plus costs of materials.


Planning and preparation for such a project might even take more time than the development process itself. With time and material model, you can start working on your project in a matter of a couple of weeks, and with a good development partner at your side, you’ll be seeing tangible results within a month. With a fixed price you’ll be getting regular reports on the progress upon achieving predetermined milestones. However, you will not be able to intervene in the development directly or make any real changes to the process. With a time and material model, though, you can get as much control and agency in the project as you want.

However, you rarely expect a price upfront for fixing a car after an accident, or for legal services to draw up a proprietary contract without a raft of ‘if ‘clauses. Less so should we expect to give a fixed price for building software, which is neither repetitive nor straightforward? An agile approach to software delivery was invented for this exact reason that it is so difficult to plan out software delivery from A to Z. Initial outsourcing agreements were traditionally built upon a fixed price model, though nowadays there is another abundantly used business model, namely time-and-material. One of the best things about fixed price is that it is rather transparent; you know exactly what you sign up for and where your money goes. No hidden catches, no charges, no surprises – everything just goes according to plan.

However, a fixed price contract can be an issue when you and the client do not come to a detailed agreement on what the work will include. You may be asked to put in many more hours of work without compensation, or the client may feel that he has overpaid for a minimal amount of work, if the contract does not include specifics. This is a fine way of controlling development costs by specifying the number of hours for which you are willing to pay. Once it’s all set and done, you will settle on the IT team that fits your scope and requirements, and the team will start the development process according to the workflow.

Advantages Of A Fixed Price Approach

T&M also requires regular communication between your team and the developers, so you’ll be spending a lot of time in meetings. Please get in touch with us if you are having difficulty selecting the appropriate model for your project. A fixed price contract defines the service to be provided very specifically, and then sets a single price for the project, regardless of how much time and expense your company incurs. Time-and-materials, on the other hand, bills the client for the hours spent on the project, as well as expenses you incur.

What is a Time And Material Model

If the price for their service seems too good to be true, you probably won’t get the results you need. If you want to meet rising client’s expectations and make your business develop constantly, then you need to take product engineering services into consideration. We at IT Master sincerely hope that these recommendations will assist you in this challenging task of coming to the right agreement with your vendor. Very often it is important to choose a Product Owner among the vendor’s team. This member is the one who cares about following the customer’s vision of the product and keeps an eye on the priorities being respected.

The Risk Is Too High

One doesn’t overpay for the risks which may not occur, but in case they take place, contrary to FP, it’s the customer who bears additional costs. With the basics out of the way, which model suits your project better? That would depend on several factors you should consider to make the right choice. Here’s our checklist for choosing between time and material vs fixed price.

Of course, we’ll stick to your budget and help you with estimating it. A Time and Material contract might be a preferable option for bigger or longer-term projects. It provides product development freedom and control while also assisting you in staying under budget. However, since there is no exact end price or deadline date, you must keep track of the expenses and the project’s progress.

A delay can make it impossible for the user to buy an item or make a sports bet, for example. Don’t have a dedicated person that could be actively involved in the project. On top of that, Adam regularly receives informationon how much he needs to pay for the agreed development period.

Time & Material

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. For the organization to have the opportunity to exist in the future, it is necessary to recognize the business prospects. Only after determining the possibilities of the business, as well as the directions and methods of its evolution, one can talk about specific strategies for growth and competition. To be able not only to assess the prospects of business correctly but also its ability to reach these goals, it is necessary to ensure or initially lay the maximum transparency and manageability. As a result, it will lead to real justification of decision-making.

No Flexibility In Reaction To Changes

The money is usually one lump sum, and you’ll get what you pay for. Dynamic work scope is one of the key features within larger projects. There can be a general goal that should be achieved, however knowing how it’ll be reached is not that important beforehand.

If you opt for the fixed cost contract, you and your software development outsource partner have to agree on the cost of the project before the process even starts. While in times and material contracts, the cost of your app development might change as the project goes on. This price arrangement provides both parties with consistency, which may be advantageous for startups or small businesses with a flexible budget. They pay the agreed-upon amount and don’t have to worry about anything else.

The first planning step provides a clear path for the development team to follow. The client does not need to have as much control over what is going on and may concentrate on other business operations. The project’s early launch will help a large number of entrepreneurs. They should also make Fixed price vs time and material choices while the development process is still in progress. This allows them to adapt to the requirements and pains of their target audience, which may change at any time. When you bill by the hour with expenses, you will be paid for your time, regardless of how long the project takes.

Sure, this solution allows you to access files, but it’s also so annoying it makes you want to shut the laptop down and grab a cup of calming tea. SAF relies on Activity result mechanics, so you can connect it with Activity Result API and enjoy a clean, well-organized code. When you want to download data for the app, you probably use the API RESTful interface. This method works well when the app doesn’t need permanent access to new information.

Everyone knows that the best ideas come to mind when you assume the role of the end-user. It’s easier to test the features and find a way to make everything work better. You can change the initial requirements or project priorities, improve some elements on the go and simply add new ideas to the backlog without renegotiating the contract and wasting your time.

Your direct competitors already have got a stronger position in the market and may react dramatically fast to change their products to outcompete you. The possibility to alter quickly and adapt to market trends, fix bugs and add features is a substantial advantage TM gives. There is a possibility of making changes during product development. There’s nothing perfect in this world, and the fixed price has its flaws too. This model would not be a good choice for a long-term project whose specs are not clearly defined. You negotiate the price and from that point on you know where the project is going.
