An order receiver, when requested to make an estimate of a product, makes an estimate and calculates a delivery time while designing the product, and notifies them to a purchaser. A purchaser (3) requests an order receiver (5) an estimate of a product. The order receiver (5) prepares a 3-D profile sketch (V) from the three-side drawings of the product. The 3-D profile sketch (V) is divided into a plurality of components for a proper working. Development drawings for respective components are produced. Material costs, blanking costs are calculated from the development drawings. Bending processes are determined from respective development drawings. Bending hours and bending costs are calculated from the bending processes. Then, the components are assembled into a product. A welding cost, painting cost and an assembling cost are calculated from the product. A delivery time and an estimate are notified to the purchaser based on the costs and times to thereby shorten a lead time in producing the product.
