Fixed Price Model

A fixed price assumes that the specifications of your product are unchangeable. This doesn't preclude the possibility of changing the specs while the project is still in progress. Just keep in mind that any suggested changes will require additional implementation costs and an analysis of the potential effects they may have on the remaining portions of the project. It's possible that some functionality has already been built in accordance with the previous specifications if the changes are made late in the project.

  • Working efficiently on projects that have clear, stable, and established requirements
  • The cost of developing an app is fixed and discussed before the project's completion.
  • Only pre-discussed "milestones" of the project are charged, and we require payment once the project is completed.

Fixed Price Model Contract Structure

Fixed-price contracts operate best when the project's cost can be predicted with confidence in advance.

The Price engagement model has several advantages, including:

  • Fixed budget and timeline.
  • The vendor accepts full responsibility for the product's quality.
  • The customer is not required to monitor the development process. In general, involvement is required only when the project's next stage is accepted. At the same time, the customer only interacts with the designated project manager, who supervises the project stages and delivery timelines.
  • Fixed development, project scope is complete.
  • Clients have very little risk, and there are no additional costs.

The following are some disadvantages of the fixed-price model:

  • Difficulty in changing the specifications after the project has begun.
  • The customer is typically not-familiar with the project's developers.
  • Less control over the project for the client.
  • Expenses for additional changes will apply.
  • The planning stage takes time.


For projects lasting 1-2 months (i.e., small mobile applications or proofs of concept), the fixed price model is preferable. The chance of requirements changing in this circumstance is low, and the project may simply be managed using the waterfall process.
