You can choose to show the Budget for the project as either a single fixed number, or as a low/high range. Initially, we highly recommend that you use the Range option, as it provides a higher degree of error, and many of your customers will likely be OK with a range during the initial design process.
The Fixed number is calculated by adding up the value of all the icons and associated products you've added to the project. Each product includes materials and labor cost and sell information.
The Range is calculated by starting with the Fixed number, then calculating a low range and a high range based on values that you manually enter.
