It’s simple. There are two ways we can design a top-notch product together – Time & Materials Based or Scope Based.The Time & Materials model is used if there is no complete vision of the final product, or if it is ongoing process and impossible to divide it into several smaller stages. We will bill by actual hours worked, as well as cost of materials necessary to complete your project.The Scope Based (also known as Project-Based) model is perfect for small and medium scope projects, where requirements, specifications, and schedules can be clearly defined before the start of the project development. You will pay a pre-determined flat fee for the entirety of the project(s).
