Estimate Outline is a business term referring to the process of systematically and accurately estimating the cost of goods, services, or projects. This process involves breaking down each component of the estimate into individual items and parameters so that the cost can be measured and itemized. By breaking the project down into distinct components, it allows for the development of a detailed budget that can be referenced throughout the life cycle of the project. With an Estimate Outline, businesses have greater control over their projects from start to finish, ensuring accuracy in both time and money.
