Time-and-Materials Model

Definition of Time and Materials

A time and material (T&M) contract assumes charging clients for actual work scope based on hourly labor rates. Customers are charged for the number of hours spent on a specific project, plus material costs. The main focus of the T&M model is its flexibility and ability to change requirements, replace features, and involve clients in order to get the exact product.

Time-and-materials

The advantages and disadvantages of the Time-and-Materials.

The advantages

  • Flexibility: Following project workflow, unit-price contracts allow businesses to change the volume of work, revise materials or designs, shift the focus, or change features. 
  • Dynamic work scope: There may be a general goal that should be achieved, but the outsourcing team can create various methods to obtain it. For startups and mid-sized businesses, it is often preferable to make decisions while developing a strategy and building custom software. This method is closely based on Agile Methodology.
  • Better timing:  By avoiding the fixed-price bidding process, vendors can save time and get started right away. Furthermore, blended rates allow you to see how much time the team devotes to each feature and commit, motivating it to work.

The disadvantages

  • Out-of-budget potential: The main disadvantage of a T&M contract is a lack of budgeting control. The total cost may exceed the budgeted amount.
  • High involvement needed: You must be actively involved to ensure that the team delivers on time and within the approved scope. (This one can be both a benefit or drawback of Time-and-Materials contracts)

Fixed-Price Model

Definition of Fixed Price

A fixed-price agreement is a one-time payment contract in which a service provider is responsible for completing the project within the agreed-upon budget. It can be a good option when the requirements, specifications, and rates are highly predictable. To ensure appropriate final results, a client should have a clear vision of the product and share it with developers.

 Fixed price

The advantages and disadvantages of the Fixed-Price.

The advantages 

  • Predictability is a high priority of any entrepreneur. Company strategy typically necessitates the transfer of clear deadlines and figures to the budget. Exact figures can be obtained by planning expenses for 1-3 months in advance. 
  • Transparency: There will be no surprises to have this benefit because the fixed-price contract has already defined specified requirements, a fixed budget, and pre-arranged deadlines from the beginning. Interaction between project managers and outsourcing developers on a regular basis ensures scope compliance and protects margins.
  • Straightforward management: Payments to service providers are typically based on a percentage of work completed. In addition, expectations are transparent and predictable, so such workflow in the fixed-price contract requires little involvement.

The Disadvantages

  • Lack of flexibility:  As a customer, vendors are responsible for any emergent changes that you initiated or that are outside the vendor’s scope of competence.
  • Less accountability has both advantages and disadvantages, depending on the circumstances. Regular reports and interactions between the client and team are not part of such an approach. Because all of the management is done by outsourced team members, you don’t need to set aside time for deep project involvement. However, this does not imply that vendors will be unaware of the workflow.
