In the product quotation input screen 1001, these pieces of information are displayed in a selectable manner in a pull-down menu, and the person in charge of the wholesaler inputs the information by appropriately selecting it using the input device of the wholesaler terminal 2.

Further, in the present embodiment, the unit price of the product, the content of the additional item and the amount thereof are input as the information indicating the content of the estimate. The person in charge of the wholesaler uses the input device of the wholesaler terminal 2 to input the product unit price and additional items such as construction to be carried out on the wholesaler side and the amount thereof. If there are no additional items, only the product unit price is entered.

When the wholesaler terminal 2 receives the product quotation information composed of each information input by the person in charge of the wholesaler (S104) and then detects the click of the send button on the product quotation input screen 1001, the product quotation information. Is transmitted to the estimation system 1 (S105).

When the quotation system 1 receives the commodity quotation information transmitted from the wholesaler terminal 2 (S203), the quotation system 1 generates each piece of information to be stored in the commodity quotation DB 163 by using the commodity quotation information and the wholesaler ID of the wholesaler who is the transmission source thereof. Then, this is registered in the product quotation DB 163 (S204).

Information is accumulated in the product quotation DB 163 by repeatedly executing the above-described product quotation registration processing by each wholesaler. The information thus accumulated will be provided to each contractor through the following product quotation provision process.

(2) Product Quotation Providing Process FIG. 9 is a flowchart showing the procedure of the product quotation providing process executed by the quotation system 1 and the contractor terminal 3.
A contractor who wants to browse the product quotation instructs the contractor terminal 3 to access the quotation system 1. The contractor terminal 3 that has received this instruction transmits a product quotation browsing request to the quotation system 1 as shown in FIG. 9 (S301).

When the quotation system 1 receives the product quotation browsing request from the construction shop terminal 3 (S401), the quotation system 1 transmits search input screen information for inputting information necessary for searching for the commodity quotation to the construction shop terminal 3 ( S402). When receiving the search input screen information (S302), the work shop terminal 3 displays the search input screen on the display screen using the search input screen information (S303).

In the case of the present embodiment, the search condition related to the product content is a search condition including items such as a category to which the product belongs, a manufacturer of the product, and a product name of the product. Similar to the case of the product quotation input screen 1001, the search input screen 2001 displays these categories, manufacturers, and product names so that they can be selected from pull-down menus. The person in charge of the work shop sets the search condition indicating the desired product by appropriately selecting using the input device of the work shop terminal 3.

Further, the search condition regarding the attribute of the wholesaler is a search condition including items such as an area to which the wholesaler belongs, a type of the wholesaler, and a form of the wholesaler. In the case of the search input screen 2001, each information item is displayed in a pull-down menu so that these items can be selected. The person in charge of the work shop uses the input device of the work shop terminal 3 to select the attribute of the desired wholesaler. At this time, the person in charge of the construction company inputs the area to which he/she belongs or the area that is the same as or near the area to which the client of the renovation work belongs, or inputs the desired type and form. Note that the attributes of this wholesaler may be entered arbitrarily, and the items may be entered only for the items that the person in charge of the construction company determines to be necessary, and may not be entered for all items.

Further, the search input screen 2001 is provided with a check box for selecting an attribute that is common to the contractor on the search side. When the person in charge of the work shop checks the check box using the input device of the work shop terminal 3, the attributes common to the work shop are selected even if each attribute is not input. Is regarded as In that case, the estimation system 1 refers to the construction shop attribute DB 162 to identify the attribute of the construction shop, and it is determined that the same attribute as the attribute of the wholesaler is selected.

The contract shop terminal 3 receives the search condition information composed of each information input by the person in charge of the contract shop (S304), and then, when it detects the click of the send button on the search input screen 2001, the search condition.

When the quotation system 1 receives the search condition information transmitted from the work shop terminal 3 (S403), the quotation system 1 refers to the wholesaler attribute DB 161 and the product quotation DB 163, and quotes the product matching the search condition included in the search condition information. Whether or not there is is determined (S404). In addition, when the search condition regarding the attribute of the wholesaler is not included in the search condition information, the presence or absence of the product estimate is determined only by the product estimate DB 163.

When it is determined in step S404 that there is a product quotation that matches the search condition (YES in S404), the quotation system 1 extracts information regarding the product quotation from the product quotation DB 163 (S405), and uses the extracted information. Search result information is generated (S406). On the other hand, when it is determined that there is no product quotation that matches the search condition (NO in S404), the quotation system 1 generates search result information including a message indicating that there is no corresponding product quotation (S406).

Next, the estimation system 1 transmits the search result screen information for outputting the search result information generated as described above to the work shop terminal 3 (S407). Here, when the search result information includes a plurality of product quotations, the search result screen information is generated so that the product quotations are displayed in descending order of employment. In that case, the quotation system 1 refers to the adoption history DB 164 to calculate the number of times the product quotation has been adopted, and generates the search result screen information so that the product quotation is displayed in descending order of the number of times.

When receiving the search result screen information transmitted from the quotation system 1 (S306), the work shop terminal 3 displays the search result screen on the display screen using the search result screen information (S307).
