How do written quotes differ from binding estimates?

Answer 1

A written quote may be either a binding or a non-binding estimate. "Non-binding estimate" means that the service provider will give an estimate of cost to the client in advance of work being done, and this estimate can be adjusted based on the nature of the task (for example, the actual length of time it took to complete the task, or the actual cost of the materials necessary). A binding estimate is also given by a service provider to a client in advance of work being done, but cannot be adjusted after the service provider has completed the work. A binding estimate requires that service provider and client agree on a fixed price in advance of the work being done.
