Time and Materials vs Fixed Price: Which Pricing Model is Better?

You've finally settled on the right software developer and it's time to set up a contract. You don't want a pricing model that will force you to renegotiate late, so you want to get it right the first time.

Let's break down two popular software project pricing models to help you make an informed decision.

Understanding Time and Materials and Fixed Price Contracts

In the world of project management, particularly in construction projects, understanding the different types of contracts is crucial. Two of the most common contract types are Time and Materials (T&M) contracts and Fixed Price contracts. Each has its unique characteristics and is suited to different project needs.

Definition and Purpose of Contracts

A contract is a legally binding agreement between two or more parties that outlines the terms and conditions of a project or service. In the context of construction projects, contracts play a crucial role in ensuring that all parties involved are aware of their responsibilities, obligations, and expectations.

Time and Materials Contracts: These contracts are designed to provide flexibility. They allow for adjustments in the scope of work as the project progresses. You pay for the actual cost of labor hours and material costs, which means you only pay for the work that is actually done. This type of contract is particularly useful in projects where the scope is not well-defined from the outset or is expected to change.

Fixed Price Contracts: On the other hand, fixed price contracts are all about predictability. You agree on a specific rate for the entire project, regardless of the actual cost incurred. This means that the contractor takes on the risk of any cost overruns. Fixed price contracts are ideal for projects with a well-defined scope and where the client wants to have a clear budget from the start.

By understanding these two types of contracts, you can better anticipate costs and choose the one that aligns with your project needs and risk tolerance.

Time and Materials vs. Fixed Price: What’s the Difference?

Let’s start by defining these terms:

Time and Materials Contract: This is where you pay for labor and expertise on an hourly basis. Time and material contracts allow for flexible pricing based on actual hours worked and materials used, benefiting both contractors and project owners, especially in projects with unpredictable scopes. You take care of their time and the cost of the materials they use to get the job done.

Fixed Price Contract: Here, you agree on a specific rate that you’ll pay for the entire process. You’re therefore to only pay that set rate, regardless of the time and resources it took to get the job done.

Many people are used to the fixed price model. It’s simply a set-and-forget model where you agree on a price and expect the job to be delivered. It may work for other services where the outcome is specific and predictable. You can easily budget for it.

However, the software development field is different. You may need quick changes to the software, which may differ from what you’d agreed on the fixed contract. That’s why today’s entrepreneurs are considering the time and materials (T&M) model.

Pros of Fixed Price Software Development Contracts

1. You work with a specific budget

As the name suggests, the price here is fixed. You just need to set aside a certain amount for the job and give specific instructions. If you've decided to spend a certain amount in 3 months, you can budget for that and confidently use your other finances on other areas of your business.

2. It's predictable

Assuming everything goes well, you can know what to expect in regards to financial costs. You simply give specifications, a deadline, and an amount. After that, you wait for the product to be delivered.

3. Minimal project management requirements

Everything is defined in the contract. Therefore, you spend little to no time managing the fixed price project. You just wait until it's done so that you can check to see if it was delivered according to your specifications.

Cons of Fixed Price Contracts

1. It's too rigid

The software market is dynamic. You can't always assume that everything will work out in a specific way. In fact, you may not know the exact needs of your users yet. A lot can change in 3-4 months. Some of these changes may force you to add features that were not included in the initial contract.

This will then require fresh negotiations, negating the set-and-go arrangement you expected and increasing the budget and time required to get the job done. If negotiations and paperwork take too long, your project can be delayed significantly.

2. Preparation and execution can take a long time

With a fixed price contract, you have a fixed scope, fixed budget and fixed time.

You'll need to take a long time studying the market and predicting what may work for your users. This may require a few sittings with your team, the development team and probably a few consultants. The contract needs to be thoroughly detailed so that the developers do not get out of scope.

Additionally, the developer needs to be okay with your budget and scope. In case they're not okay with it, you may need to get back to the table again.

3. There are significant risks involved

Even the best laid plans can fail. It doesn't matter how meticulous your plan is. Something crucial may change. And this can mess up everything, forcing you back to the drawing board.

There are many risk factors here. Things like communication challenges, changes in the software environment, new studies, legal requirements and market changes can give you a headache.

And remember that you will have to pay for each new change that was not covered in the contract.

Advantages of Time and Materials Contracts

1. Ultimate flexibility

This model is very flexible. Generally, you won’t come across issues when making changes, since you’re only paying for the work that’s actually been done according to your hourly rates. However, incorporating a clause for maximum labor hours can help in managing budget constraints and anticipating costs.

You can easily modify the scope of work, request for addition or removal of features, and use flexible (agile) software development methodologies.

2. Maximize the value of time

You don't have to spend too much time drafting specifications. You can start with the idea and keep developing it with the team overtime. This helps you to deliver the MVP to users faster and get feedback on its value.

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. It helps you not to overdesign or overpay your developer for things that don't work with your users.

4. Get better value for money

You’re in business, so you want to make sure that every dime you spend brings in value, right? The time and materials contract will help you test things faster with users. You can then focus on features that bring in the highest returns to your business. Additionally, these contracts often require separate fixed hourly rates for each labor category, ensuring transparency in billing.

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. These contracts also define specified fixed hourly rates for labor performed by contractors, encompassing wages, overhead, general and administrative expenses, and profit.

You can verify the time logged by the developer so that you’re not overcharged. And as you keep testing and optimizing useful features, you may end up spending less money than a developer would have quoted for a fixed price agreement.

Disadvantages of Time and Materials Pricing Models

1. Your budget is not specific

This can be good if you end up going below your expected budget. However, should it take longer to implement some features, you may end up spending more than you had planned.

2. Heavy involvement

You will need to stay involved with the process. To optimize performance, you may need to use project management and time tracking software. You'll have to keep making decisions as you test every iteration. You therefore have to be ready for involvement in your project.

The Verdict: Which Pricing Contract is Better?

So, what should you choose for your software project?

It may be so tempting to go for the fixed price model. It looks like it will save you a few bucks. You'll have a specific deadline and scope of work. However, you can never ignore the fact that software projects change quickly, and a significant change can cause a disaster.

A time and materials contract makes more sense in software development work. Here, you get the ultimate flexibility and speed that you really need. You can get started with a project right away and keep testing and optimizing it. You can focus your energy on what works best. You're not just waiting on a deadline (that may need to be extended anyway).
