While both Quotation and Estimator roles involve cost assessment, a Quotation provides a fixed price for a specific project, whereas an Estimator prepares preliminary cost estimates to guide decision-making and bidding processes. The Quotation is final and specific, while the Estimator's work is more variable and preparatory.
