If developing software was the same as building a house…

Software Development Models Explained: Outsourcing vs Outstaffing, Fixed Price vs Time & Material

Do you agree that in order to achieve an effective result in business, each process must be managed by authorized professionals in a particular field? But at the same time, maintaining a highly specialized team of professionals to carry out each process is not a “cheap” decision. If you and your company are interested in minimizing the risks and costs of production processes that do not constitute the main direction but are related to the latter this article will be useful to you.

As we know, choosing a software development company is easy. If you have done it a few times already. If you are a first-timer or even a second-timer – it is a hell of a challenge. And when you are finally almost sure that this is the company you want to cooperate with, they ask you: “Which software development model do you prefer, outsourcing vs outstaffing, “Fixed Price”or ”Time & Material”?”. Here we go again, the things become dizzying.

To make your life a tiny bit easier, I am here with a concise comparison of the essential software development models. So, let me show you what is the difference between outsourcing and outstaffing and between the “Fixed Price” approach and the ”Time & Material” approach. To make it crystal clear, I will use the example of a house.

Outsourcing vs Outstaffing

This question most certainly will throw you off if you have little to no experience with software development agencies: “Outsourcing or outstaffing”? The two models are similar, both stand for offshore software development, and both offer dedicated developers. How do you tell them apart? How do you make the rights choice?


Let’s start with outsourcing software development – a more complex approach. Imagine that you have no in-house development team, no technical specialists in your company, but you need to develop a software product. If it is only one project, which will be completed and closed in a few months, does it make sense to recruit in-house developers? Most likely, even if you decide to invest in hiring, onboarding, training, and then, offboarding, professional engineers will not be willing to start working with you full-time for such a short period of time. In this case, the more rational choice is to outsource your project to an external team of developers – an outsourcing provider.

Outsourcing means giving your software product idea to a remote development team and them giving you a final product. The outsourcing software development team composition depends on your project requirements – it may or may not involve business analytics or UI/UX designers, but it must involve software engineers, QA specialists, and a Project Manager. If you partner up with outsourcing companies, you are free to choose whether you want to monitor the project closely or you fully trust a PM with it. 

The House Example

For example, you want to build a house, but you do not want to build it yourself. You hire a construction team, tell them your wishes or show blueprints if you have any, and leave them to it. Building the house is their job now. You can visit the construction site daily or weekly, or you may even come back a year later when it is entirely done. Once they finish, you shake on it, finish all the payments and documents, and tell the goodbyes. Now, the house is all yours.

Pros of Outsourcing

  • Convenience

You can focus only on core functions and concentrate on key directions, assigning others to secondary tasks.

  • No management effort

The performance of important functions is outsourced to contractors. Therefore, the required corporate result is achieved via external efforts.

  • Cost reduction

Since certain business responsibilities are assigned to a partner, the company has no need to pay its own employees for the same services and saves money.

Cons of Outsourcing

  • Less control over the quality

To entrust the performance of certain functions to a partner means disrupting the corporate unity of the company. If the contractor does not bring the desired result, the company can face risks and losses.

So What?

The clear advantages of outsourcing prevail over the disadvantages. This tendency ensures the growing popularity of outsourcing all over the world. The main idea behind outsourcing is to reduce gross costs and give you the chance to manage the company’s resources more effectively. However, the main benefit is the opportunity to use someone else’s highly-specialized expertise and information accumulated through years. 


The circumstances when you would require outstaffing services are different. To engage in outstaffing, you must have an in-house development team. Imagine that you have a team of developers, designers, testers, PMs, whom you have hired permanently and who work full-time with you. What if at some point you have some urgent development needs, and the team has no time or resources to manage them? You can hire another full-time specialist if the increased scope of work is going to persist. If the increase in workload is a temporary issue, you should engage in outstaffing instead.

Outstaffing equals hiring a remote full-time or part-time specialist, who will act as a temporary member of your in-house team. This model lets you hire basically any software development specialists or a couple of them – depending on your project needs. Outstaffing, however, requires project management to be ensured on your side.

The House Example

Imagine that you have decided to build a house yourself, and your friends or relatives agreed to help you. The work on it is long underway, but at some point, you realize that you have nobody who knows how to deal with wood. You go to a local construction company and sign an agreement with a carpenter, who will now work hand-in-hand with your development team. After their job is done, you end the cooperation and proceed to do what you have to.

Pros of Outstaffing

  • Simplicity

Outstaffing greatly simplifies personnel management: vacations, sick leaves, salary payments, compliance with social guarantees — all these bureaucratic issues remain in the area of responsibility of the outstaffer company.

  • Less hiring effort

An employer does not waste time looking for a candidate because the outstaffing company itself selects a suitable specialist for them.

  • Cost reduction

Cons of Outstaffing

  • The need to have an in-house team

You still should have to have an in-house team to rely on. While you make use of outstaffing services to ease the workload, you should have in-house employees to keep the company’s strategy in the right direction. 

So What?

Undoubtedly, the main benefit of outstaffing is the optimization of the economic model of a company, along with cost reduction. Outstaffing significantly reduces costs, minimizes the expenses of your company related to non-core business processes. In addition, this model allows you to get rid of the costs of financial and resource maintenance of employees.

Fixed Price vs Time & Material

Supermarkets have fixed prices for everything they have in stock. Banks have fixed commissions. Service providers like barbershops or gyms also offer a price that you know beforehand. And that works perfectly fine. When you start a software project, you would also expect to know its price in advance. You would want to compare the prices of different vendors and to know which budget you need to cover. 

So, you go to a software vendor and ask something like “How much would it cost to build a website?”. If the vendor is honest with you and respects your business, you will not get an answer immediately. There’s a good reason for that: websites may be quite different, and the word “website” does not tell much about the things you have on your mind. Sadly, a note that “it’s an e-shop” will not help much here either. If at this point, you get a simple answer about the price, you definitely want to think twice before partnering up with this vendor.

At KeenEthics, for the time being, we have never had two identical projects. Obviously, most of them have had something in common. For example, you would need a login feature for most web-applications. But even login flow might have quite a lot of differences. Do you need social login? If so, which social networks should be supported? Do you need password recovery? 

There are two models that will help you decide on project pricing – Fixed Price approach and Time & Material approach.

Fixed Price

The Fixed Price approach lets you know the project price beforehand. You negotiate and confirm the price, and this is how much you will pay once you receive the final product. A conscientious software vendor would try to figure out all your requirements. Here, you will have to answer multiple questions starting with the overall business idea and finishing with minor login details. The UX-expert might try to prepare mockups of the final product, which you will be expected to critique. All the information will be documented, detailed, and decomposed into actual tasks. Only after that, the software engineers will estimate the time needed to complete each objective. Based on this estimation, the actual price will be calculated. Obviously, this takes quite some time. For larger projects, it might take months to finalize and document all the requirements, which increases the end price of the project.

However convenient it sounded, this approach is quite risky. In most cases, following this approach still will not give you a 100% accurate estimate. As a rule, the estimation process is conducted with the help of previous experience and intuition, which still leaves some room for deviations. Deviations produce risks. And risks also make their way into the final price. One side is always losing. Either the price is too high and you end up overpaying, or the price estimate is too low and the software development company is left underpaid. The latter case bears an important risk to you as well – as soon as the software development company starts going beyond the budget, they may compromise quality in the pursuit of ending the project sooner to reduce expenses. 

The Fixed Price approach is sometimes employed in outsourcing but almost never used in outstaffing.

The House Example

You negotiate the price of the house with your construction team. They review all the requests and blueprints, ask you about everything in the smallest details, and tell you the final price of the house, which includes labor costs, costs of materials, and costs of equipment. Now you know the final price, so you can start planning your budget and collecting the necessary amount of money. When you are shown the completed house, you have to pay the negotiated price, and it is not important if the currency rates changed, the work was finished much sooner than expected, or the resources appeared to be quite cheaper than expected. Also, if you want to implement some slight changes, you have to sign a separate contract and negotiate a different price because these changes were not covered in the previous one.

“Time & Material” Approach

The Fixed Price approach has a simple and flexible alternative – “Time & Material”. Prior to the project start, the team gives rough estimates, and if confirmed, they proceed to development. Each specialist is assigned a certain hourly rate. The cost of the project is counted as the rates of each specialist multiplied by the number of hours spent. Sometimes, it may also include the costs of necessary resources, such as Jira or some technology license. “Time & Material” approach also takes into account the number of hours spent working overtime or during the weekend. This model is much fairer than the other one because the development team is paid as much as they have worked.  It also enables the development process to start much faster and gives the customer a high flexibility to change requirements on the go.

This model, however, requires trustworthy relationships between the client and the development team. If you have no confidence in the development team and you are not sure that they will tell you the truth, you risk losing money. It happens that developers record more hours than they actually spent working. Unfortunately, it is something you cannot prevent. The most you can do to protect your budget from somebody’s greediness is to communicate closely with developers, to be open with them, and to keep the healthy atmosphere in the team.

“Time & Material” model is equally used in both outsourcing and outstaffing. 

The House Example

You hire a construction team to build your house, they look at blueprints and tell you the approximate cost of your project. You agree that they keep track of all the resources they use and of the number of hours they spend working. Another important point to discuss is how and when you make payments. You do not know exactly how much the house will cost, so you probably should start collecting a bit more money than was estimated. When the house is being built, you can introduce changes to requirements freely. For instance, you want the porch to be made out of wood, not bricks. Each month or after the house completion, depending on the initial agreement, you meet with the team and review their cost records. If there are no questions, you proceed with the payment. Yet, you better make sure that the team is a trustworthy one, or they still some materials from you.
