Time and Materials (T&M) is a business engagement model commonly used in professional services and engineering industries. T&M is based on the idea that clients pay for the amount of time required to complete a project as well as the materials/products used. This model allows clients to have more control over the costs associated with their project by suggesting changes in scope or implementing cost-saving measures along the way. T&M provides the flexibility that certain projects may need, allowing the client to pay only for what they use rather than budgeting for a set number of hours ahead of time. By taking into account the changing needs of their project, T&M gives companies the power to make sure they get exactly what they’re paying for— quality products delivered on time.
