Invoicing
Estimate
A non-binding written quote of the cost of a job, sent before work begins.
Definition
An estimate gives the customer an expected price range based on scope, materials, and labor. It is not a legal commitment to a final price — that's a quote. Many trades convert approved estimates directly into invoices once the job is complete.
